              PROSPECTUS AND PROXY STATEMENT - _______, 1996 

        Acquisition of the assets of Calvert U.S. Government Fund 
           By and in exchange for shares of Calvert Income Fund 
    4550 Montgomery Avenue, Bethesda, Maryland 20814 - (800) 368-2745 

         This Prospectus and Proxy Statement relates to the proposed  
transfer of all the assets and the assumption of certain identified  
liabilities of the Calvert U.S. Government Fund ("Government Fund") to  
the Calvert Income Fund ("Income Fund") (collectively, "the Funds") in  
exchange for like shares of Income Fund. Following the transfer, Income  
Fund shares will be distributed to shareholders of Government Fund in  
liquidation of Government Fund, and Government Fund will be dissolved.  
As a result of the proposed transaction, each shareholder of Government  
Fund will receive that number of like Income Fund shares equal in value  
at the date of the exchange to the value of such shareholder's shares of  
Government Fund. The transaction will occur if shareholders vote in  
favor of the proposed transfer. 

         Income Fund is a series of The Calvert Fund ("Calvert"), which  
is an open-end management investment company. The net assets of Income  
Fund were $43,402,592 as of September 30, 1995. Its investment objective  
is to maximize long-term income, to the extent consistent with prudent  
investment management and preservation of capital, primarily through  
investment in investment grade bonds and other income producing  
securities. Income Fund is non-diversified. Debt securities may be  
long-term, intermediate-term, short-term, or any combination thereof,  
depending on the Advisor's evaluation of current and anticipated trends. 

         Government Fund is also a series of Calvert, with assets of  
$9,472,160 as of September 30, 1995. Its investment objective is to seek  
to provide high current income consistent with safety of principal by  
investing in a professionally managed portfolio consisting primarily of  
U.S. Government-backed obligations. There is no limitation on the  
maturity of obligations in which Government Fund may invest. 

         Income Fund and Government Fund both have a 3.75% maximum sales  
charge for Class A Shares. The sales charge is added to the purchase  
price of shares, but will not be applied to shares issued in the  
reorganization (see "Purchase Procedures"). Class C Shares have a level  
load charged as higher expenses rather than a front-end sales charge.  
Both funds have distribution plans that permit them to pay certain  
expenses associated with the distribution of their shares. Calvert Asset  
Management Company, Inc. ("Advisor") is the investment advisor for both  
Income Fund and Government Fund. 

         This Prospectus and Proxy Statement, which should be retained  
for future reference, sets forth concisely the information about Income  
Fund that a prospective investor should know before investing. This  
Prospectus and Proxy Statement is accompanied by the Prospectus of  
Income Fund dated January 31, 1995 as revised September 30, 1995 and is  
incorporated herein by reference. A Statement of Additional Information  
dated January 31, 1995 and revised September 30, 1995 containing  
additional information has been filed with the Securities and Exchange  
Commission and is incorporated by reference into this Prospectus and  
Proxy Statement. A copy of the Statement may be obtained without charge  
by writing Income Fund at 4550 Montgomery Avenue, Suite 1000N, Bethesda,  
Maryland 20814, or by calling (800) 368-2748. 

THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES  
AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION, NOR HAS THE  
SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION  
PASSED ON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY  
REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE. 

SHARES OF THE FUND ARE NOT DEPOSITS OR OBLIGATIONS OF, OR GUARANTEED OR  
ENDORSED BY, ANY BANK, AND ARE NOT FEDERALLY INSURED BY THE FDIC, THE  
FEDERAL RESERVE BOARD, OR ANY OTHER AGENCY.

                                 SUMMARY 

         Reasons for the Reorganization. The Board of Trustees of The  
Calvert Fund (the "Trustees") have been considering the problems  
inherent in the small size of the Government Fund, and have concluded  
that by combining the Government Fund into the larger Income Fund, the  
assets could be more efficiently managed in an effort to reduce expenses  
and enhance returns. The Income Fund has more than four times the net  
assets of Government Fund. At fiscal year-end, on September 30, 1995,  
Income Fund had net assets of $43,402,592, compared to $9,472,160 for  
Government Fund. 

         In evaluating the benefits of the proposed transaction, the  
Board of Trustees considered the effect of the loss of a portion of the  
capital loss carryforwards that might be available to Government Fund.  
It has been determined that the benefits of the proposed reorganization  
outweigh the uncertain potential detriment resulting from possible  
constraints in the use of capital loss carryforwards. See "Information  
about the Reorganization." 

         Proposed Transaction. The Trustees have authorized Calvert, on  
behalf of the funds, to enter into an Agreement and Plan of  
Reorganization (the "Agreement" or "Plan") providing for the transfer of  
all the assets and liabilities of Government Fund to Income Fund in  
exchange for like shares of Income Fund. Following the transfer, Income  
Fund shares will be distributed to shareholders of Government Fund in  
liquidation of Government Fund, and Government Fund will be dissolved.  
As a result of the proposed transaction, each shareholder of Government  
Fund will receive that number of full and fractional Income Fund shares  
equal in class and value at the date of the exchange to the class and  
value of such shareholder's shares of Government Fund. For the reasons  
stated above, the Trustees, including the independent Trustees, have  
concluded that the reorganization would be in the best interests of the  
shareholders of Government Fund and recommend shareholder approval. 

         Tax Consequences. The Plan is conditioned upon receipt by  
Government Fund of an opinion of counsel that no gain or loss will be  
recognized by Government Fund or Government Fund shareholders as a  
result of the reorganization. The tax basis of Income Fund shares  
received by a shareholder will be the same as the tax basis of the  
shareholder's Government Fund shares. In addition, the tax basis of  
Government Fund assets in the hands of Income Fund as a result of the  
reorganization will be the same as the tax basis of such assets in the  
hands of Government Fund prior to the reorganization. See "Information  
about the Reorganization." 

         Investment Policies. Shareholders should consider the  
differences in investment policies between Government Fund and Income  
Fund. While both Funds seek income, the Government Fund pursues high  
current income, and the Income Fund seeks to maximize long-term income.  
Thus, the focus of each investment portfolio is different. Government  
Fund invests primarily in U.S. Government obligations. Income Fund  
purchases corporate bonds and other income-producing securities,  
including U.S. Government obligations. See "Comparison of Investment  
Policies." 

         Advisory Fees, Distribution Fees and Expense Ratios. Income  
Fund pays the Advisor a fee computed on average daily net assets at an  
annual rate of 0.70%. Government Fund pays the Advisor a fee computed on  
average daily net assets at an annual rate of 0.60%.  Total Fund Operation
Expenses, however, are less for Income Fund and are not expected to increase 
significantly (see "ProForma" on the next page).

The example, which is hypothetical, should not be considered a  
representation of past or future expenses. Actual expenses and return  
may be higher or lower than those shown. 

Explanation of Table: The purpose of the table is to assist you in  
understanding the various costs and expenses that an investor in the  
Funds may bear directly (shareholder transaction costs) or indirectly  
(annual fund operating expenses). 

      A. Shareholder Transaction Costs are charges you pay when you buy  
or sell shares of a Fund. 

      B. Annual Fund Operating Expenses. Management Fees are paid by the  
Funds to Calvert Asset Management Company, Inc. ("Investment Advisor")  
for managing the Funds' investments and business affairs. The Funds  
incur Other Expenses for maintaining shareholder records, furnishing  
shareholder statements and reports, and other services. Management Fees  
and Other Expenses have already been reflected in the Funds' share price  
and are not charged directly to individual shareholder accounts. If  
Management had not reimbursed or waived fees, the current Other Expenses  
and Total Fund Operating Expenses for Class A Shares of Income Fund  
would have been 0.31% and 1.26%, respectively. For Class C shares, the  
current Other Expenses and Total Fund Operating Expenses for Class A  
Shares of Income Fund would have been 1.77% and 3.37%, respectively. If  
Management had not reimbursed or waived fees, the current Other Expenses  
and Total Fund Operating Expenses for Class A shares of Government Fund  
would have been 0.80% and 1.62%, respectively. For Class C shares, the  
current Other Expenses and Total Fund Operating Expenses for Class A  
Shares of Income Fund would have been 1.93% and 3.53%, respectively. 

      The Fund's Rule 12b-1 fees include an asset-based sales charge.  
Thus, long-term shareholders in the Fund may pay more in total sales  
charges than the economic equivalent of the maximum front-end sales  
charge permitted by rules of the National Association of Securities  
Dealers, Inc. 

         Under the terms of their Distribution Plans, the Funds are  
permitted to pay annually a percentage of their average daily net assets  
for certain expenses associated with the distribution of their shares.  
The maximum percentage allowed by contract is 0.50% and .90% for Class  
A and C Shares of the Income Fund, respectively, and 0.25% and 1.00% for  
Class A and C Shares of the Government Fund, respectively. Although the  
Income Fund's maximum annual Rule 12b-1 fee for Class A Shares is 0.50%,  
the Income Fund currently charges 0.25%. Amounts paid by the funds to  
the underwriter/distributor, Calvert Distributors, Inc. ("CDI"), under  
the Class A Distribution Plan are used to pay to dealers and others,  
including CDI salespersons who service accounts, service fees at an  
annual rate of up to 0.25% of the average daily net asset value of Class  
A shares, and to pay CDI for its marketing and distribution expenses,  
including, but not limited to, preparation of advertising and sales  
literature and the printing and mailing of prospectuses to prospective  
investors. During the fiscal year ended September 30, 1995, Class A  
Distribution Plan expenses for the Income and Government Funds were  
0.15% and 0.23%, respectively. Amounts paid by the funds under the Class  
C Distribution Plan are currently used by CDI to pay dealers and other  
selling firms dealer-paid quarterly compensation at an annual rate of up  
to 0.75%, plus a service fee of up to 0.25%, of the average daily net  
asset value of each share sold by such others. For the fiscal year ended  
September 30, 1995, Class C Distribution Plan expenses were .90% and  
1.00% for the Income and Government Funds, respectively. 

FINANCIAL HIGHLIGHTS 

The following  tables provide information  about the financial history  
of each Fund's Class A and C shares. They express the information in  
terms of a single share outstanding for the respective Fund throughout  
each period. The tables have been audited by those independent  
accountants whose reports are included in the respective Annual Reports  
to Shareholders of the Funds. The tables should be read in conjunction  
with the financial statements and their related notes. The current  
Annual Reports to Shareholders are incorporated by reference into the  
Statement of Additional Information.

         The total return figures shown above include the effect of the  
maximum sales charge of 3.75% for Class A Shares, changes in share  
price, and reinvestment of dividends and distributions. Total return is  
based on historical earnings and asset value fluctuations and is not  
intended to indicate future performance. No adjustments are made to  
reflect any income taxes payable by shareholders. 

         Purchases. Class A Shares of both Government Fund and Income  
Fund are sold on a continuous basis at net asset value plus the  
appropriate sales charge which is subject to reduction by right of  
accumulation, group purchase, and letter of intent. Employee purchases  
and certain plans qualified under the Internal Revenue Code may purchase  
shares with no sales charge, and all Fund shareholders may reinvest  
dividends without paying a sales charge. Class A Shares issued in the  
reorganization will not be assessed any sales charge. Class C Shares do  
not have a front-end sales charge.

*For new investments (new purchases but not exchanges) of $1 million or  
more a broker-dealer will have the choice of being paid a finder's fee  
by CDI in one of the following methods: (1) CDI may pay broker-dealers,  
on a monthly basis for 12 months, an annual rate of 0.30%. Payments will  
be made monthly at the rate of 0.025% of the amount of the investment,  
less redemptions; or (2) CDI may pay broker-dealers 0.25% of the amount  
of the purchase; however, CDI reserves the right to recoup any portion  
of the amount paid to the dealer if the investor redeems some or all of  
the shares from the fund(s) within thirteen months of the time of  
purchase. 

         The minimum initial investment in each fund is $2,000 and the  
minimum subsequent investment is $250 (except in the case of certain  
retirement plans). 

         Exchange Privileges. Shareholders of both Government Fund and  
Income Fund may exchange fund shares for shares of a variety of other  
Calvert Group funds. Each such exchange represents a sale of fund  
shares, which may produce a gain or loss for tax purposes. Shares are  
exchanged into the same class. There is no additional charge for  
exchanges. Calvert Group discourages frequent exchanges and may prohibit  
additional purchases of shares by persons who have previously been  
advised that their frequent use of the exchange privilege is  
inconsistent with the orderly management of the investment portfolio.  
Government Fund and Income Fund reserve the right to modify or eliminate  
this exchange privilege with 60 days' written notice. 

         Distribution Procedures. Both Government Fund and Income Fund  
distribute dividends monthly and pay out their net realized capital  
gains (if any) once each year. Shareholders of both funds may reinvest  
distributions. Your existing election in Government Fund with respect to  
dividends and/or capital gains will be continued with respect to the  
shares of Income Fund you acquire in connection with the reorganization  
unless you notify the Fund of a new election. 

         Redemption Procedures. At any time and in any amount, shares of  
Government Fund and Income Fund may be redeemed by submitting a written  
request by mail. All written orders for redemption, and all accompanying  
certificates, must be signed by the shareholder and may be required to  
be signature guaranteed by a commercial bank, savings association, trust  
company or member firm of any national securities exchange. Further  
documentation may be required from corporations, fiduciaries, pension  
plans and institutional investors. 

         Shares may also be redeemed by telephone or through brokers.  
Both funds impose a charge of $5.00 for wire transfers of less than  
$1,000. Government Fund and Income Fund may, after 30 days' notice,  
close accounts if the value of shares in the account is reduced by  
redemptions to less than $1,000, and the investor fails to purchase  
sufficient additional shares. 

COMPARISON OF INVESTMENT POLICIES 

         As noted in the "Summary" above, the investment policies of the  
two funds are different. While both Funds seek income, the  
Government Fund invests only in U.S. Government-backed obligations to  
produce high current income. Examples of U.S. Government-backed  
obligations include mortgage pass-through certificates, such as GNMAs;  
direct obligations of the United States Treasury, such as U.S. Treasury  
bills, notes, and bonds; obligations issued or guaranteed by the U.S.  
Government, its agencies or its instrumentalities; collateralized  
mortgage obligations; and U.S. Government-backed obligations subject to  
repurchase agreements. Income Fund can purchase not only U.S.  
Government-backed obligations, but also corporate obligations, foreign  
securities, and other income-producing securities. 

         In seeking to maximize long-term income, Income Fund invests  
80% of its assets in corporate obligations and other fixed-income  
securities. At least 65% of its assets at the date of investment are  
rated within the four highest grades established by Moody's Investor  
Services, Inc. ("Moody's"), or by Standard & Poor's Corporation ("S&P")  
(grades AAA/Aaa through Baa/BBB). The remaining 35% of assets may consist  
of other debt securities, including bonds rated below Baa/BBB. With  
lower rated bonds, there is a greater possibility that an adverse change  
in the financial condition of the issuer may affect its ability to pay  
principal and interest. In addition, to the extent Income Fund holds  
such bonds, it may be negatively affected by adverse economic  
developments, increased volatility or a lack of liquidity.
 
         Income Fund may also purchase obligations issued or guaranteed  
as to principal by the U.S. Government or its agencies or  
instrumentalities; certificates of deposit, time deposits, and bankers'  
acceptances of U.S. banks and their branches located outside of the U.S.  
and of U.S. branches of foreign banks, provided that the bank has total  
assets of at least one billion dollars or the equivalent in other  
currencies; commercial paper which at the date of investment is rated  
Prime-2 or better by Moody's, A-2 or better by S&P, or, if not rated, is  
of comparable quality as determined by the Advisor; and any of the above  
securities subject to repurchase agreements with recognized securities  
dealers and banks. Up to 20% of Income Fund's total assets may consist  
of other debt securities, including securities convertible into or  
carrying warrants to purchase common stock or other equity securities  
and income-producing preferred and common stocks. 

         Income Fund is a nondiversified fund. There may be risks  
associated with nondiversification. Specifically, since a relatively  
high percentage of the assets may be invested in the obligations of a  
limited number of issuers, the value of the shares may be more  
susceptible to any single economic, political, or regulatory event than  
the shares of a diversified fund. 

         Income Fund may invest in options and futures to increase or  
decrease its exposure to changing security prices, interest rates,  
currency exchange rates, or other factors that affect security value.  
These techniques may involve derivative transactions such as buying and  
selling options and futures contracts and leveraged notes, entering into  
currency exchange contracts, or swap agreements, and purchasing indexed  
securities. Income Fund can use these practices either as substitution  
or as protection against an adverse move in its portfolio to adjust the  
risk and return characteristics. If the Advisor judges market conditions  
incorrectly or employs a strategy that does not correlate well with  
Income Fund's investments, or if the counterparty to the transaction  
does not perform as promised, these techniques could result in a loss.  
These techniques may increase the volatility of the portfolio and may  
involve a small investment of cash relative to the magnitude of the risk  
assumed. 

INFORMATION ABOUT THE REORGANIZATION 

         Plan of Reorganization. The proposed Agreement and Plan of  
Reorganization (the "Agreement" or "Plan") provides that Income Fund  
will acquire all the assets and liabilities of Government Fund in  
exchange for shares of Income Fund on the Closing Date (as defined in  
Section 2(b) of the Plan). A copy of the Plan is attached as Exhibit A  
to this Proxy Statement. The number of full and fractional Income Fund  
shares to be issued to shareholders of Government Fund will equal the  
value of the shares of Government Fund outstanding immediately prior to  
the reorganization. Portfolio securities of Government Fund and Income  
Fund will be valued in accordance with the valuation practices of Income  
Fund which are described on page 15 of the Income Fund prospectus and on  
page 13 of its Statement of Additional Information. At the time of the  
reorganization, Income Fund will assume and pay all of Government Fund's  
obligations and liabilities. The reorganization will be accounted for by  
the method of accounting for tax-free reorganizations of investment  
companies, sometimes referred to as the "pooling without restatement"  
method. Any reimbursement due from the Advisor to Government Fund under  
the expense limitation provision will be paid at, or prior to, the  
closing. 

         As soon as practicable after the Closing Date, Government Fund  
will liquidate and distribute pro rata to its shareholders of record as  
of the close of business on the Closing Date the full and fractional  
shares of Income Fund at an aggregate net asset value equal to the value  
of the shareholder's investment in Government Fund next determined after  
the effective time of the transaction. This method of valuation is also  
consistent with interpretations of Rule 22c-1 under the Investment  
Company Act of 1940 by the Securities and Exchange Commission's Division  
of Investment Management. Such liquidation and distribution will be  
accomplished by the establishment of accounts on the share records of  
Income Fund in the name of such Government Fund shareholders, each  
representing the respective pro rata number of full and fractional  
shares of Income Fund due the shareholder. Certificates representing  
shares of Government Fund at the Closing Date will represent the shares  
of Income Fund distributed to the recordholder thereof as a result of  
the liquidation of Government Fund. New certificates for Income Fund  
shares will be issued only upon written request, and only upon tender of  
Government Fund certificates. 

         The consummation of the Plan is subject to the conditions set  
forth in the Agreement. The Plan may be terminated and the  
reorganization abandoned at any time before or after approval by  
Government Fund shareholders, prior to the Closing Date by mutual  
consent of Government Fund and Income Fund, or by either if any  
condition set forth in the Plan has not been fulfilled or is waived by  
the party entitled to its benefits. In accordance with the Plan,  
Government Fund and Income Fund will each be responsible for payment of  
expenses incurred in connection with the reorganization. 

         Description of Income Fund Shares. Full and fractional shares  
of Income Fund will be issued to Government Fund shareholders per class  
in accordance with the procedures under the Plan as described above.  
Each share will be fully paid and nonassessable when issued and  
transferable without restrictions and will have no preemptive or  
conversion rights. 

         Federal Income Tax Consequences. The Plan is a tax-free  
reorganization pursuant to Section 368(a)(1)(C) of the Internal Revenue Code.  
The Plan is conditioned upon the issuance of an opinion by outside  
counsel to the Fund, to the effect that, on the basis of the existing  
provisions of the Internal Revenue Code of 1986, current administrative  
rules and court decisions, for federal income tax purposes: (1) No gain  
or loss will be recognized by Government Fund or Income Fund upon the  
transfer of Government Fund assets to, and the assumption of its  
liabilities by, Income Fund in exchange for Income Fund shares (Section  
1032(a)); (2) no gain or loss will be recognized by shareholders of  
Government Fund upon the exchange of Government Fund shares for Income  
Fund shares (Section 361(a)); (3) the basis and holding period immediately  
after the reorganization for Income Fund shares received by each  
Government Fund shareholder pursuant to the reorganization will be the  
same as the basis and holding period of Government Fund shares held  
immediately prior to the exchange (Section 354, 356); and (4) the basis and  
holding period immediately after the reorganization of Government Fund  
assets acquired by Income Fund will be the same as the basis and holding  
period of such assets of Government Fund immediately prior to the  
reorganization (Section 362(b), 1223(2)). 

         Opinions of counsel are not binding on the Internal Revenue  
Service or the courts. If the reorganization is consummated but does not  
qualify as a tax-free reorganization under the Internal Revenue Code,  
the consequences described above would not be applicable. Shareholders  
of Government Fund should consult their tax advisors regarding the  
effect, if any, of the proposed reorganization in light of their  
individual circumstances. Since the foregoing discussion relates only to  
the federal income tax consequences of the reorganization, shareholders  
of the Government Fund should also consult their tax advisors as to the  
state and local tax consequences, if any, of the reorganization.

         Other Tax Consequences.  Many states do not tax income received
from U.S. Government obligations.  Because of the diversity of Income Fund 
investments, however, the percentage of income a shareholder receives from
U.S. Government obligations may be less than that of Government Fund.  

         Effect of the Reorganization on Capital Loss Carryforwards. The  
following tables provide comparative information regarding realized  
capital gains and losses and net unrealized appreciation or depreciation  
of portfolio securities of Income Fund and Government Fund as of  
September 30, 1995, and the capital loss carryforwards of each at the  
end of its last fiscal year. 

Income Fund 

         Capital Loss Carryforward at 9/30/95                  $174,409 
         Realized gains (losses) 10/1/94 - 9/30/95            ($197,657) 
         Net unrealized appreciation at 9/30/95                $703,207 

Government Fund 

         Capital Loss Carryforward at 9/30/95                  $424,163 
         Realized gains (losses) 10/1/94 - 9/30/95            ($117,178) 
         Net unrealized appreciation at 9/30/95                $113,449 

         If the reorganization does not occur, Government Fund's capital  
loss carryforwards should be available to offset any net realized  
capital gains of Government Fund through 2002 and 2003. It is  
anticipated that no distributions of net realized capital gains would be  
made by Government Fund until the capital loss carryforwards expire or  
are offset by net realized capital gains. 

         If the reorganization is consummated, Income Fund will be  
constrained in the extent to which it can use the capital loss  
carryforwards of Government Fund because of limitations imposed by the  
Internal Revenue Code on the occurrence of an ownership change. Income  
Fund should be able to use in each year a capital loss carryforward in  
an amount equal to the value of Government Fund on the date of the  
reorganization multiplied by a long-term tax-exempt rate calculated by  
the Internal Revenue Service. If the amount of such a loss is not used  
in one year, it may be added to the amount available for use in the next  
year. For 1995, the amount of capital loss carryforward that may be used  
under the formula will be further reduced to reflect the number of days  
remaining in the year following the date of the reorganization. 

         It appears that the anticipated benefits outweigh the uncertain  
potential detriment resulting from the partial loss of capital loss  
carryforwards, and the differing consequences of federal and various  
other income taxation on a distribution received by each shareholder  
whose tax liabilities (if any) are determined by the net effect of a  
multitude of considerations that are individual to the shareholder.  
Government Fund shareholders who need information as to state and local  
tax consequences, if any, should consult their tax advisors. 

         Capitalization. The following table shows the capitalization of  
Government Fund and Income Fund as of September 30, 1995, and on a pro  
forma basis as of that date of the proposed acquisition of assets at net  
asset value: 

                                    Government       Income        Pro Forma  
Combined* 
Net Assets                          $9,472,160       $43,402,592   $52,874,752 
Net Asset Value 
Per Share, Class A                  $14.61           $16.82        $16.82 
Net Asset Value 
Per Share, Class C                  $14.49           $16.56        $16.56 
Shares Outstanding 
Class A                             618,647          2,534,815     3,072,177 
Shares Outstanding 
Class C                             30,048           46,243        72,535 

         *The Pro Forma combined net assets does not reflect  
adjustments with respect to distributions prior to the  
reorganization. Total Income Fund Class A shares issued pro  
forma to Government Fund shareholders would be 537,362 and  
26,292 for Class C. For each Class A share of Government Fund  
shares owned, shareholders of Government Fund would receive pro  
forma approximately 0.875 Class A shares of Income Fund. For  
each Class C share of Government Fund shares owned,  
shareholders of Government Fund would receive pro forma  
approximately 0.868 Class C shares of Income Fund. The actual  
exchange ratio will be determined based on the relative net  
asset value per share on the acquisition date. 

 COMPARATIVE INFORMATION ON SHAREHOLDER RIGHTS 

         Both funds are series of the same open-end management  
 investment company that is organized as a Massachusetts trust, and as  
 such share a common Declaration of Trust and Bylaws. After the merger,

 properly brought before the meeting, the persons named in the  
 accompanying form of proxy will vote thereon in accordance with their  
 judgment. 

 VOTING INFORMATION 

         Proxies from the shareholders of Government Fund are being

revoked at any time before the meeting or during the meeting by oral or  
written notice to William M. Tartikoff, Esq., Secretary, 4550  
Montgomery Avenue, Suite 1000N, Bethesda, Maryland 20814. Unless  
revoked, all valid proxies will be voted in accordance with the  
specification thereon or, in the absence of specification, for approval  
of the Plan. Approval of the Plan will require the affirmative vote of

Government Fund entitled to vote at the meeting. 

         Proxies are solicited by mail. Additional solicitations may be  
 made by telephone, computer communications, facsimile or other such  
 means, or by personal contact by officers or employees of Calvert Group  
 and its affiliates or by proxy soliciting firms retained for this  
 purpose. Government Fund and Income Fund will each bear their  
 appropriate share of solicitation costs. 

         Shareholders of Government Fund of record at the close of

 of and to vote at the Special Meeting or any adjournment thereof. The  
 holders of a majority of the shares of Government Fund outstanding at  
 the close of business on the record date present in person or  
 represented by proxy will constitute a quorum for the meeting; however,  
 as noted above, the affirmative vote of the holders of at least a  
 majority of the shares outstanding at the close of business on the

                   AGREEMENT AND PLAN OF REORGANIZATION 

         This AGREEMENT AND PLAN OF REORGANIZATION, dated as of December 19,  
1995 is between Calvert U.S. Government Fund (Government Fund) and  
Calvert Income Fund (Income Fund). Government Fund and Income Fund are  
both series of The Calvert Fund (Calvert). 

         In consideration of the mutual promises contained in this  
Agreement, the parties agree as follows: 

1.       SHAREHOLDER APPROVAL 

         Approval by Shareholders. A meeting of the shareholders of  
Government Fund shall be called and held for the purpose of acting on  
and authorizing the transactions contemplated in this Agreement and Plan  
of Reorganization (the Agreement or Plan). Income Fund shall furnish to  
Government Fund such data and information as shall be reasonably  
requested by Government Fund for inclusion in the information to be  
furnished to its shareholders in connection with the meeting. 

2.       REORGANIZATION 

         (a) Plan of Reorganization. Government Fund will convey,  
transfer, and deliver to Income Fund all of the then-existing assets of  
Government Fund at the closing provided for in Section 2(b) of this  
Agreement (the Closing). In consideration thereof, Income Fund agrees at  
the Closing: 

                  (i) to assume and pay, to the extent that they exist on  
or after the Effective Time of the Reorganization (as defined in Section  
2(b)), all of Government Fund's obligations and liabilities, whether  
absolute, accrued, contingent, or otherwise; and 

                  (ii) to deliver to Government Fund in exchange for the  
assets the number of full and fractional shares of common stock of  
Income Fund (Income Fund Shares) to be determined as follows: In  
accordance with Section 3 of this Agreement, the number of shares shall  
be determined by dividing the per share net asset value of Government  
Fund Shares (rounded to the nearest mill) by the net asset value per  
share of Income Fund (rounded to the nearest mill) and multiplying the  
quotient by the number of outstanding shares of Government Fund as of  
the close of business on the closing date. It is expressly agreed that  
there will be no sales charge to Government Fund, or to any of the  
shareholders of Government Fund upon distribution of Income Fund Shares  
to them. 

         (b) Closing and Effective Time of the Reorganization. The  
Closing shall occur at the Effective Time of the Reorganization, which  
shall be either 

                  (i) the later of receipt of all necessary regulatory  
approvals and the final adjournment of the meeting of shareholders of  
Government Fund at which the Plan will be considered, or 

                  (ii) such later date as the parties may mutually agree. 

3.       VALUATION OF NET ASSETS 

         (a) The value of Government Fund's net assets to be transferred  
to Income Fund under this Agreement shall be computed as of the close of  
business on the business day immediately preceding the Closing Date  
(hereinafter the Valuation Date) using the valuation procedures as set  
forth in Income Fund's prospectus. 

         (b) The net asset value per share of Income Fund Shares for  
purposes of Section 2 of this Agreement shall be determined as of the  
close of business on the Valuation Date by Income Fund's Controller  
using the same valuation procedures as set forth in Income Fund's  
prospectus. 

         (c) A copy of the computation showing in reasonable detail the  
valuation of Government Fund's net assets to be transferred to Income  
Fund pursuant to paragraph 2 of this Agreement, certified by the  
Controller of Government Fund, shall be furnished by Government Fund to  
Income Fund at the Closing. A copy of the computation showing in  
reasonable detail the determination of the net asset value per share of  
Income Fund Shares pursuant to paragraph 2 of this Agreement, certified  
by the Controller of Income Fund, shall be furnished by Income Fund to  
Government Fund at the Closing. 

4.       LIQUIDATION AND DISSOLUTION 

         (a) As soon as practicable after the Closing Date, Government  
Fund will distribute pro rata to the Government Fund shareholders of  
record as of the close of business on the Closing Date the shares of  
Income Fund received by Government Fund pursuant to this Section. Such  
liquidation and distribution will be accompanied by the establishment of  
Shareholder accounts on the share records of Income Fund in the names of  
each such shareholder of Government Fund, representing the respective  
pro rata number of full shares and fractional interests in shares of  
Income Fund due to each. No such shareholder accounts shall be  
established by Income Fund or its transfer agent for Income Fund except  
pursuant to written instructions from Government Fund, and Government  
Fund agrees to provide on the Closing Date instructions to transfer to a  
shareholder account for each former Government Fund shareholder a pro  
rata share of the number of shares of Income Fund received pursuant to  
Section 2(a) of this Agreement. 

         (b) Promptly after the distribution described in Section 4(a)  
above, appropriate notification will be mailed by Income Fund or its  
transfer agent to each shareholder of Government Fund receiving such  
distribution of shares of Income Fund informing such shareholder of the  
number of such shares distributed to such shareholder and confirming the  
registration thereof in such shareholder's name. 

         (c) Following the Closing Date and until surrendered, each  
outstanding share certificate representing shares of Government Fund  
shall be deemed for all purposes to evidence ownership of shares of  
Income Fund that the holder is entitled to receive in exchange for the  
certificate. The shares of Income Fund that the holder is entitled to  
receive with respect to Government Fund's share certificates not yet  
surrendered will be held by Income Fund's transfer agent on behalf of  
the shareholder, but may not be transferred or redeemed until surrender  
of Government Fund's share certificates in proper form for transfer to  
Income Fund's transfer agent or, in lieu thereof, the posting of a lost  
certificate bond or other surety instrument deemed acceptable to Income  
Fund's transfer agent. All of Income Fund's distributions attributable  
to the shares represented by the share certificates of Government Fund  
retained by shareholders will be paid to the shareholder in cash or  
invested in additional shares of Income Fund at the net asset value in  
effect on the respective payment dates in accordance with instructions  
previously given by the shareholder to Government Fund's transfer agent.  
Share certificates representing holdings of shares of Income Fund shall  
not be issued unless requested by the shareholder and, if such a request  
is made, share certificates of Income Fund will be issued only for full  
shares of Income Fund and any fractional interests in shares shall be  
credited in the shareholder's account with Income Fund. 

         (d) As promptly as is practicable after the liquidation of  
Government Fund, and in no event later than 12 months from the date of  
this Agreement, Government Fund shall be terminated pursuant to the  
provisions of the Plan and The Calvert Fund's Declaration of Trust. 

         (e) Immediately after the Closing Date, the share transfer  
books of Government Fund shall be closed and no transfer of shares shall  
thereafter be made on those books. 

5.       TRUST and BY-LAWS 

         (a) Declaration of Trust. The Declaration of Trust of Calvert,  
which governs its series Income Fund, as in effect immediately prior to  
the Effective Time of the Reorganization shall continue to be the  
Declaration of Trust until amended as provided by law. 

         (b) By-laws. The By-laws of Calvert, which govern its series  
Income Fund, in effect at the Effective Time of the Reorganization shall

         (c) Opinion of Counsel. Income Fund shall have received the

actual or constructive) of Income Fund Shares to its shareholders in  
exchange for their shares of beneficial interest of Government Fund; 

                  (ii) the shareholders of Government Fund who receive  
Income Fund Shares pursuant to the Reorganization will not recognize any  
gain or loss upon the exchange (whether actual or constructive) of their  
shares of capital stock of Government Fund for Income Fund Shares

received) pursuant to the Reorganization; 

                  (iii) the basis of Income Fund Shares received by  
Government Fund's shareholders will be the same as the basis of the  
shares of capital stock of Government Fund surrendered in the exchange;  
and 

                  (iv) the basis of Government Fund assets acquired by  
Income Fund will be the same as the basis of such assets to Government  
Fund immediately prior to the Reorganization.

         AND REPRESENTATIONS

material covenant of Income Fund contained in this Agreement is not

Item 15. Indemnification 

         Registrant's Declaration of Trust, which Declaration is Exhibit  
1 of the Initial Registration Statement dated August 1, 1986, provides,  
in summary, that officers, trustees, employees, and agents shall be  
indemnified by Registrant against liabilities and expenses incurred by  
such persons in connection with actions, suits, or proceedings arising  
out of their offices or duties of employment, except that no  
indemnification can be made to such a person if he has been adjudged  
liable of willful misfeasance, bad faith, gross negligence, or reckless  
disregard of his duties. In the absence of such an adjudication, the  
determination of eligibility for indemnification shall be made by  
independent counsel in a written opinion or by the vote of a majority of  
a quorum of trustees who are neither "interested persons" of Registrant,  
as that term is defined in Section 2(a)(19) of the Investment Company  
Act of 1940, nor parties to the proceeding. 

         Registrant's Declaration of Trust also provides that Registrant  
may purchase and maintain liability insurance on behalf of any officer,  
trustee, employee or agent against any liabilities arising from such  
status. In this regard, Registrant maintains a Directors & Officers  
(Partners) Liability Insurance Policy with Chubb Group of Insurance  
Companies, 15 Mountain View Road, Warren, New Jersey 07061, providing  
Registrant with $5 million in directors and officers liability coverage,  
plus $3 million in excess directors and officers liability coverage for  
the independent trustees/directors only. Registrant also maintains an $8  
million Investment Company Blanket Bond issued by ICI Mutual Insurance  
Company, P.O. Box 730, Burlington, Vermont, 05402.

                  The Calvert Fund 

Ladies and Gentlemen: 

         As counsel to The Calvert Fund (the "Trust"), it is my opinion,  
based upon an examination of the Trust's Declaration of Trust and  
By-Laws and such other original or photostatic copies of Trust records,  
certificates of public officials, documents, papers, statutes, and  
authorities as I deemed necessary to form the basis of this opinion,  
that the securities being registered by this Registration Statement  
will, when sold, be legally issued, fully paid and non-assessable. 

         Consent is hereby given to file this opinion of counsel with  
the Securities and Exchange Commission as an Exhibit to this  
Registration Statement. 


                                                     Sincerely,

Re:      Acquisition of Assets of Calvert U.S. Government Fund  

Ladies and Gentlemen: 

         You have asked for our opinion as to certain tax 
consequences of the proposed acquisition of assets of Calvert 
U.S. Government Fund ("Selling Fund"), a series of 
The Calvert Fund, a Massachusetts business trust (the 
"Company"), by Calvert Calvert Income Fund ("Acquiring Fund"),
also a series of the Company, in exchange for 
voting shares of Acquiring Fund (the "Reorganization"). 

         In rendering our opinion, we have reviewed and relied upon 
the draft Prospectus/Proxy Statement dated December 13, 1995 and 
the Agreement and Plan of Reorganization (the "Agreement") 
dated as of December 19, 1995.  We have relied, without 
independent verification, upon the factual statements made 
therein, and assume that there will be no change in material 
facts disclosed therein between the date of this letter and the 
date of closing of the Reorganization.  We further assume that 
the Reorganization will be carried out in accordance with the 
Agreement.  We have also relied upon the following 
representations, each of which has been made to us by officers of 
the Company on behalf of Acquiring Fund or of Selling Fund: 

                  The Reorganization will be consummated substantially 
as described in the Agreement. 

                  Acquiring Fund will acquire from Selling Fund at least 
90% of the fair market value of the net assets and at least 70% 
of the fair market value of the gross assets held by Selling Fund 
immediately prior to the Reorganization.  For purposes of this 
representation, assets of Selling Fund used to pay reorganization 

<PAGE>

Calvert U.S. Government Fund
Calvert Income Fund

Page 2 


expenses, cash retained to pay liabilities, and redemptions and 
distributions (except for regular and normal distributions) made 
by Selling Fund immediately preceding the transfer which are part 
of the plan of reorganization, will be considered as assets held 
by Selling Fund immediately prior to the transfer. 

                  To the best of the knowledge of management of Selling 
Fund, there is no plan or intention on the part of the 
shareholders of Selling Fund to sell, exchange, or otherwise 
dispose of a number of Acquiring Fund shares received in the 
Reorganization that would reduce the former Selling Fund 
shareholders' ownership of Acquiring Fund shares to a number of 
shares having a value, as of the date of the Reorganization 
(the "Closing Date"), of less than 50 percent of the value of all 
of the formerly outstanding shares of Selling Fund as of the same 
date.  For purposes of this representation, Selling Fund shares 
exchanged for cash or other property will be treated as 
outstanding Selling Fund shares on the Closing Date.  There are 
no dissenters' rights in the Reorganization, and no cash will 
be exchanged for Selling Fund shares in lieu of fractional shares 
of Acquiring Fund.  Moreover, shares of Selling Fund and shares 
of Acquiring Fund held by Selling Fund shareholders and otherwise 
sold, redeemed, or disposed of prior or subsequent to the 
Reorganization will be considered in making this 
representation, except for shares of Selling Fund or Acquiring 
Fund redeemed in the ordinary course of business of Selling Fund 
or Acquiring Fund in accordance with the requirements of section 
22(e) of the Investment Company Act of 1940. 

                  Selling Fund has not redeemed and will not redeem the 
shares of any of its shareholders in connection with the 
Reorganization except to the extent necessary to comply with 
its legal obligation to redeem its shares. 

                  The management of Acquiring Fund has no plan or 
intention to redeem or reacquire any of the Acquiring Fund shares 
to be received by Selling Fund shareholders in connection with 
the Reorganization, except to the extent necessary to comply 
with its legal obligation to redeem its shares. 

                  The management of Acquiring Fund has no plan or 
intention to sell or dispose of any of the assets of Selling Fund 
which will be acquired by Acquiring Fund in the Reorganization, 
except for dispositions made in the ordinary course of business,

and to the extent necessary to enable Acquiring Fund to comply 
with its legal obligation to redeem its shares. 

                  Following the Reorganization, Acquiring Fund will 
continue the historic business of Selling Fund in a substantially 
unchanged manner as part of the regulated investment company 
business of Acquiring Fund, or will use a significant portion of 
Selling Fund's historic business assets in a business. 

                  There is no intercorporate indebtedness between 
Acquiring Fund and Selling Fund. 

                  Acquiring Fund does not own, directly or indirectly, 
and has not owned in the last five years, directly or indirectly, 
any shares of Selling Fund.  Acquiring Fund will not acquire any 
shares of Selling Fund prior to the Closing Date. 

                  Acquiring Fund will not make any payment of cash or of 
property other than shares to Selling Fund or to any shareholder 
of Selling Fund in connection with the Reorganization. 

                  Pursuant to the Agreement, the shareholders of Selling 
Fund will receive solely Acquiring Fund voting shares in exchange 
for their voting shares of Selling Fund. 

                  The fair market value of the Acquiring Fund shares to 
be received by the Selling Fund shareholders will be 
approximately equal to the fair market value of the Selling Fund 
shares surrendered in exchange therefor. 

                  Subsequent to the transfer of Selling Fund's assets to 
Acquiring Fund pursuant to the Agreement, Selling Fund will 
distribute the shares of Acquiring Fund, together with other 
assets it may have, in final liquidation as expeditiously as 
possible. 

                  Selling Fund is not under the jurisdiction of a court 
in a Title 11 or similar case within the meaning of 
Section 368(a)(3)(A) of the Internal Revenue Code of 1986, as amended 
(the "Code"). 

                  Selling Fund is treated as a corporation for federal 
income tax purposes and at all times in its existence has 
qualified as a regulated investment company, as defined in Section 851 
of the Code.

                  Acquiring Fund is treated as a corporation for federal 
income tax purposes and at all times in its existence has 
qualified as a regulated investment company, as defined in Section 851 
of the Code. 

                  The sum of the liabilities of Selling Fund to be 
assumed by Acquiring Fund and the expenses of the 
Reorganization does not exceed twenty percent of the fair 
market value of the assets of Selling Fund. 

                  The foregoing representations are true on the date of 
this letter and will be true on the date of closing of the 
Reorganization. 

         Based on and subject to the foregoing, and our examination 
of the legal authority we have deemed to be relevant, it is our 
opinion that for federal income tax purposes: 

           The acquisition by Acquiring Fund of substantially all 
of the assets of Selling Fund solely in exchange for voting 
shares of Acquiring Fund followed by the distribution by Selling 
Fund of said Acquiring Fund shares to the shareholders of Selling 
Fund in exchange for their Selling Fund shares will constitute a 
reorganization within the meaning of Section 368(a)(1)(C) of the Code, 
and Acquiring Fund and Selling Fund will each be "a party to a 
reorganization" within the meaning of Section 368(b) of the Code. 

           No gain or loss will be recognized to Selling Fund upon 
the transfer of substantially all of its assets to Acquiring Fund 
solely in exchange for Acquiring Fund voting shares and 
assumption by Acquiring Fund of certain identified liabilities of 
Selling Fund, or upon the distribution of such Acquiring Fund 
voting shares to the shareholders of Selling Fund in exchange for 
all of their Selling Fund shares.   

           No gain or loss will be recognized by Acquiring Fund 
upon the receipt of the assets of Selling Fund (including any 
cash retained initially by Selling Fund to pay liabilities but 
later transferred) solely in exchange for Acquiring Fund voting 
shares and assumption by Acquiring Fund of certain identified 
liabilities of Selling Fund.   

           The basis of the assets of Selling Fund acquired by 
Acquiring Fund will be the same as the basis of those assets in 
the hands of Selling Fund immediately prior to the transfer, and

the holding period of the assets of Selling Fund in the hands of 
Acquiring Fund will include the period during which those assets 
were held by Selling Fund.   

           The shareholders of Selling Fund will recognize no gain 
or loss upon the exchange of all of their Selling Fund shares 
solely for Acquiring Fund voting shares.  Gain, if any, will be 
realized by Selling Fund shareholders who in exchange for their 
Selling Fund shares receive other property or money in addition 
to Acquiring Fund shares, and will be recognized, but not in 
excess of the amount of cash and the value of such other property 
received.  If the exchange has the effect of the distribution of 
a dividend, then the amount of gain recognized that is not in 
excess of the ratable share of undistributed earnings and profits 
of Selling Fund will be treated as a dividend.   

           The basis of the Acquiring Fund voting shares to be 
received by the Selling Fund shareholders will be the same as the 
basis of the Selling Fund shares surrendered in exchange 
therefor.  

           The holding period of the Acquiring Fund voting shares 
to be received by the Selling Fund shareholders will include the 
period during which the Selling Fund shares surrendered in 
exchange therefor were held, provided the Selling Fund shares 
were held as a capital asset on the date of the exchange. 

         This opinion letter is delivered to you in satisfaction of 
the requirements of sections 8.D. and 9.D. of the Agreement.  We hereby 
consent to the filing of this opinion as an exhibit to the 
Registration Statement on Form N-14 and to use of our name and 
any reference to our firm in the Registration Statement or in the

THE CALVERT FUND 
Calvert U. S. Government Fund 
Calvert Income Fund 
4550 Montgomery Avenue, Bethesda, Maryland 20814 

INVESTMENT OBJECTIVES 

Calvert U.S.  Government  Fund seeks to provide high current  income  consistent
with safety of  principal by investing  in a  professionally  managed  portfolio
consisting  primarily  of  U.S.  Government-backed   obligations.  There  is  no
limitation on the maturity of obligations in which Calvert U.S.  Government Fund
may invest.

Calvert Income Fund seeks to maximize long-term income, to the extent consistent
with  prudent  investment  management  and  preservation  of  capital,   through
investment in bonds and other income  producing  securities of investment  grade
quality.

Each Fund offers two classes of shares,  each with different  expense levels and
sales  charges.  You may  choose to  purchase  (i) Class A shares,  with a sales
charge imposed at the time you purchase the shares  ("front-end  sales charge");
or (ii) Class C shares  which  impose  neither a  front-end  sales  charge nor a
contingent  deferred sales charge.  Class C shares are not available through all
dealers.  Class C shares have a higher  level of  expenses  than Class A shares,
including  higher Rule 12b-1 fees. These  alternatives  permit you to choose the
method of purchasing  shares that is most  beneficial  to you,  depending on the
amount of the  purchase,  the length of time you expect to hold the shares,  and
other circumstances. See "Alternative Sales Options" for further details.

TO OPEN AN ACCOUNT 

Call your  broker,  or complete  and return the  enclosed  Account  Application.
Minimum investment is $2,000 per Fund.

A. Shareholder Transaction Costs are charges you pay when you buy or sell shares
of the Fund.  See "Reduced Sales Charges" at Exhibit A to see if you qualify for
possible  reductions  in the sales charge.  If you request a wire  redemption of
less than $1,000, you will be charged a $5 wire fee.

B.  Annual  Fund  Operating  Expenses.  Management  Fees are paid by the Fund to
Calvert Asset Management Company, Inc.  ("Investment  Advisor") for managing the
Funds'  investments  and business  affairs.  The Funds incur Other  Expenses for
maintaining shareholder records,  furnishing shareholder statements and reports,
and  other  services.  Management  Fees and Other  Expenses  have  already  been
reflected in the Funds' share price and are not charged  directly to  individual
shareholder  accounts.  Please  refer to  "Management  of the Fund" for  further
information.

The Fund's Rule 12b-1 fees include an  asset-based  sales  charge.  Thus,  it is
possible  that  long-term  shareholders  in the Fund may pay more in total sales
charges  than the  economic  equivalent  of the maximum  front-end  sales charge
permitted by rules of the National Association of Securities Dealers, Inc.

C.  Example of  Expenses.  The  example,  which is  hypothetical,  should not be
considered a  representation  of past or future  expenses.  Actual  expenses and
return may be higher or lower than those shown.

INVESTMENT OBJECTIVES AND POLICIES 

Calvert  U.S.  Government  Fund  invests  primarily  in  U.S.  Government-backed
obligations.

Calvert U.S.  Government  Fund seeks to provide high current  income  consistent
with safety of  principal by investing  in a  professionally  managed  portfolio
consisting primarily of U.S. Government-backed obligations. There is no limit on
the maturity of securities in which Calvert U.S. Government Fund may invest.

Under normal  circumstances,  this Fund attempts to invest 100% of its assets in
U.S. Government-backed obligations which include:

(1)  Mortgage  pass-through  certificates  issued  by  the  Government  National
Mortgage Association (known as "GNMAs" or "Ginnie Maes");

(2) Direct  obligations  of the United  States  Treasury  which  consist of U.S.
Treasury  bills (having  maturities of one year or less),  U.S.  Treasury  notes
(having  maturities  of one to ten years)  and U.S.  Treasury  bonds  (generally
having maturities greater than ten years);

(3)  Obligations  issued or  guaranteed  by the United  States  Government,  its
agencies,  or its  instrumentalities  which are supported by: (a) the full faith
and credit of the U.S.  Government  (for example,  GNMAs);  (b) the right of the
issuer to borrow an amount  limited  to a  specific  line of credit for the U.S.
Government  (for  example,   obligations  of  the  Federal   National   Mortgage
Association,  known as  "Fannie  Maes");  and (c) the  credit  of the  agency or
instrumentality  (for  example,  obligations  of the Federal Home Loan  Mortgage
Corporation, known as "Freddie Macs");

(4) Securities  collateralized  by the  mortgage-related  obligations  described
above ("collateralized mortgage obligations" or "CMOs"); and

(5) U.S.  Government-backed  obligations  subject to repurchase  agreements with
recognized securities dealers and banks.

The Advisor  anticipates  that a  substantial  portion of the  Government-backed
obligations in Calvert U.S.  Government  Fund's  portfolio will consist of GNMAs
although there is no set percentage that must be invested in GNMAs.

Calvert  Income  Fund  invests in  corporate  bonds.  80% of its assets  must be
invested in bonds of investment grade quality.

Calvert Income Fund seeks to maximize long-term income, to the extent consistent
with  prudent  investment  management  and  preservation  of capital,  primarily
through  investment  in  investment  grade  bonds  and  other   income-producing
securities. Debt securities may be long-term, intermediate-term,  short-term, or
any combination  thereof,  depending on the Advisor's  evaluation of current and
anticipated  market  patterns  and trends.  The Advisor  expects that the Fund's
average weighted maturity will range between 5 and 20 years.

Calvert Income Fund invests 80% of its assets in corporate  obligations which at
the date of investment are rated within the four highest  grades  established by
Moody's Investors Services, Inc. (Aaa, Aa, A, or Baa), or by Standard and Poor's
Corporation (AAA, AA, A, or BBB), or if not rated, are of comparable  quality as
determined  by the Advisor.  Though still  investment  grade,  securities  rated
BBB/Baa possess certain speculative  elements and are generally more susceptible
to changing  market  conditions.  All fixed  income  instruments  are subject to
interest-rate  risk;  that is, when  market  interest  rates  rise,  the current
principal value of a bond will decline.

The  remaining  20% of the  Fund's  total  assets  may  consist  of  other  debt
securities (see below)  including bonds rated below BBB or Baa  ("non-investment
grade  securities,"  commonly  known as "junk  bonds").  With lower rated bonds,
there is a greater possibility that an adverse change in the financial condition
of the issuer may affect its ability to pay principal and interest. In addition,
to the extent the Fund holds any such bonds,  it may be  negatively  affected by
adverse economic developments,  increased volatility or a lack of liquidity. See
the Statement of Additional Information, "Non-Investment Grade Debt Securities,"
and bond ratings.

Calvert  Income Fund may also  purchase  obligations  issued or guaranteed as to
principal  by  the  U.S.  Government  or  its  agencies  or   instrumentalities;
certificates of deposit,  time deposits,  and bankers' acceptances of U.S. banks
and their branches  located outside of the U.S. and of U.S.  branches of foreign
banks,  provided that the bank has total assets of at least one billion  dollars
or the  equivalent in other  currencies;  commercial  paper which at the date of
investment  is rated  Prime-2 or better by Moody's,  A-2 or better by Standard &
Poor's, or, if not rated, is of comparable quality as determined by the Advisor;
and any of the above securities subject to repurchase agreements with recognized
securities  dealers and banks. Up to 20% of the value of the Fund's total assets
may consist of other debt securities (including  securities  convertible into or
carrying  warrants to purchase  common  stock or other  equity  securities)  and
income-producing preferred and common stocks.

GNMA Certificates 

GNMA  Certificates,   or  GNMAs,  are  mortgage-backed  securities  representing
ownership of mortgage or  construction  loans that are issued by lenders such as
mortgage  bankers,  commercial  banks and savings and loan  associations and are
either  insured by the  Federal  Housing  Administration  or  guaranteed  by the
Veterans Housing  Administration.  The GNMA may be secured by a single mortgage,
such as a large  multi-family  housing  development,  or, more  typically,  by a
"pool" or group of single-family housing mortgages.

Once  approved by GNMA,  the timely  payment of interest  and  principal on each
mortgage  is  guaranteed  by GNMA and backed by the full faith and credit of the
U.S. Government.  GNMAs differ from bonds in that principal is paid back monthly
by the borrower  over the term of the loan rather than returned in a lump sum at
maturity.  GNMAs are called "pass-through"  securities because both interest and
principal payments  (including  prepayments) are passed through to the holder of
the GNMA.  Upon  receipt,  principal  payments will be reinvested by the Fund in
additional  securities at the then  prevailing  interest rate. The amount of any
premium that may be paid upon purchase of a GNMA is not guaranteed.  The Advisor
will attempt, through careful evaluation of available GNMA issues and prevailing
market conditions, to invest in GNMAs which provide a high income return but are
not subject to substantial risk of loss of principal.  Accordingly,  the Advisor
may forgo the  opportunity  to invest in  certain  issues of GNMAs  which  would
provide a high  current  income yield if the Advisor  believes  that such issues
would be subject to a risk of prepayment or loss of principal over the long-term
that would outweigh the short-term increment in yield.

Collateralized Mortgage Obligations 

Collateralized  mortgage  obligations  ("CMOs")  are bonds which are the general
obligations  of the bond issuer.  CMOs may be issued by  governmental  entities,
such  as  the  Federal  Home  Loan   Mortgage   Corporation   (FHLMC),   and  by
non-governmental  entities,  such as banks  and  other  mortgage  lenders.  CMOs
generally are secured by collateral consisting of individual mortgages or a pool
of  mortgages.  CMOs are not  direct  obligations  of the  Government.  However,
Calvert  U.S.  Government  Fund will  purchase  only  those  CMOs which are U.S.
Government-backed   obligations   (those  that  are  secured  by   mortgages  or
mortgage-related  obligations  which  are  issued  or  guaranteed  by  the  U.S.
Government, its agencies or its instrumentalities).

FNMA and FHLMC Certificates 

Each Fund may invest in pass-through certificates issued by the Federal National
Mortgage  Association  ("FNMA")  and  Federal  Home  Loan  Mortgage  Corporation
("FHLMC").  Unlike GNMAs,  which are  typically  interests in pools of mortgages
insured  or  guaranteed  by  government  agencies,  FNMA and FHLMC  certificates
represent undivided interests in pools of conventional mortgage loans.

Financial Futures, Options, and Other Investment Techniques 

Each Fund can use various  techniques  to increase or decrease  its  exposure to
changing security prices,  interest rates, or other factors that affect security
values. These techniques may involve derivative  transactions such as buying and
selling options and futures contracts and leveraged notes (U.S.  Government Fund
only),  entering into swap agreements,  and purchasing indexed  securities.  The
Fund can use these practices either as substitution or as protection  against an
adverse   move  in  the  Fund's   portfolio   to  adjust  the  risk  and  return
characteristics of the Fund's portfolio. If the Advisor judges market conditions
incorrectly  or employs a strategy that does not correlate  well with the Fund's
investments,  or if the  counterparty  to the  transaction  does not  perform as
promised, these techniques could result in a loss. These techniques may increase
the volatility of a fund and may involve a small  investment of cash relative to
the magnitude of the risk assumed. Any instruments determined to be illiquid are
subject to the Fund's 10% restriction on illiquid securities.  See the Statement
of Additional Information for more detail about these strategies.

Each Fund may enter into repurchase  agreements and may purchase securities on a
forward or when-issued basis.

In a  repurchase  agreement,  the Fund buys a security  subject to the right and
obligation to sell it back at a higher price.  These  transactions must be fully
secured at all times, but they involve some credit risk to the Fund if the other
party  defaults  on its  obligation  and the Fund is delayed or  prevented  from
liquidating the collateral.

Purchasing  obligations  for future  delivery  or on a  "when-issued"  basis may
increase the Fund's overall  investment  exposure and involves a risk of loss if
the  value  of the  securities  declines  prior  to  the  settlement  date.  The
transactions are fully secured at all times.

Foreign Investments 

Calvert  Income Fund may invest up to 20% of its assets in securities of foreign
issuers,  provided such securities are denominated in U.S.  dollars and trade on
domestic securities exchanges or over-the-counter securities markets. Securities
of foreign  issuers may offer  greater  potential  for capital  appreciation  or
income than the securities of domestic issuers and may involve  investment risks
that are greater than those inherent in the securities of domestic issuers. Such
differences   might   possibly   result  from  future   political  and  economic
developments,  disparities  in  economic  systems,  and  imposition  of  foreign
governmental restrictions. There may also be less publicly available information
about a foreign  issuer than about a domestic  issuer;  foreign  issuers are not
generally  subject to uniform  auditing,  accounting and reporting  requirements
comparable to those applicable to domestic issuers.

Other Policies 

Calvert  Income Fund has the  authority to invest in restricted  securities  and
covered call options, and international money market instruments, and may borrow
money from banks as a temporary measure for extraordinary or emergency purposes.
However,  it does not hold,  and in the coming year it does not plan to acquire,
more  than 5% of the  value of its  assets  in  these  types  of  securities  or
practices.  An  explanation  of such  investment  policies  is set  forth in the
Statement of Additional Information.

Each Fund may lend its  portfolio  securities  to  member  firms of the New York
Stock Exchange and commercial  banks with assets of $1 billion or more, but only
if the value of the securities  loaned from a Fund will not exceed  one-third of
the Fund's assets.

The Funds have adopted certain  fundamental  investment  restrictions  which are
discussed  in  detail  in  the  Statement  of  Additional  Information.   Unless
specifically   noted   otherwise,   the  investment   objective,   policies  and
restrictions  of the  Funds  are  fundamental  and  may not be  changed  without
shareholder approval.

Although  U.S.  Government-backed  obligations  in each Fund's  portfolio may be
guaranteed by the  Government,  a Fund's net asset value per share and yield are
not guaranteed and will change in response to market conditions. There can be no
assurance that any Fund will be successful in meeting its investment objective.

YIELD AND TOTAL RETURN 

The Funds may advertise yield and total return for each class. 

Yield measures the current  investment  performance  for each class of the Fund,
that is, the rate of income on its  portfolio  investments  divided by the share
price.  Yield  is  computed  by  annualizing  the  result  of  dividing  the net
investment  income per share over a 30-day period by the maximum  offering price
per share on the last day of that  period.  Yields are  calculated  according to
accounting methods that are standardized for all stock and bond funds.

Both yield and total return are based on historical results and are not intended
to indicate future performance.

Total return is calculated  separately for each class.  It includes not only the
effect of income  dividends but also any change in net asset value, or principal
amount,  during the stated period. The total return of a class shows its overall
change in value, including changes in share price and assuming all of the class'
dividends and capital gain  distributions  are  reinvested.  A cumulative  total
return reflects the class'  performance over a stated period of time. An average
annual total return  reflects the  hypothetical  annual  compounded  return that
would have produced the same cumulative total return if the performance had been
constant over the entire period.  Because  average annual returns tend to smooth
out variations in the returns,  you should  recognize that they are not the same
as actual year-by-year  results. Both types of total return usually will include
the effect of paying the front-end sales charge,  in the case of Class A shares.
Of course,  total  returns  will be higher if sales  charges  are not taken into
account.  Quotations of "overall  return" do not reflect  deduction of the sales
charge.  You should  consider  overall  return figures only if you qualify for a
reduced sales  charge,  or for purposes of comparison  with  comparable  figures
which also do not reflect sales charges,  such as mutual fund averages  compiled
by Lipper  Analytical  Services,  Inc.  Further  information  about  the  Fund's
performance  is contained  in its Annual  Report to  Shareholders,  which may be
obtained without charge.

MANAGEMENT OF THE FUND 

The Trust's Board of Trustees  supervises the Trust's activities and reviews its
contracts with companies that provide it with services
 .
Calvert U.S.  Government  Fund and Calvert Income Fund are series of The Calvert
Fund (the  "Trust"),  an  open-end  diversified  management  investment  company
organized as a Massachusetts  business trust on March 15, 1982. The other series
of the Fund are  Calvert  Strategic  Growth  Fund and  Calvert  Short-Term  U.S.
Government Fund.

The Trust is not  required  to hold  annual  shareholder  meetings,  but special
meetings may be called for certain purposes such as electing Trustees,  changing
fundamental policies, or approving a management contract. As a shareholder,  you
receive one vote for each share of a Fund you own.  For matters  affecting  only
one Fund,  only  shares of that Fund are  entitled  to vote.  Matters  affecting
classes differently,  such as Distribution Plans, will be voted on separately by
the affected class(es).

Portfolio Managers 

Investment  selections  for the Funds are made by Colleen M. Denzler and Stephen
N. Van Order.  Ms.  Denzler has been with the Calvert Group since 1986,  and has
been a member of the Portfolio Investment  Department since January 1987. She is
a member of the  Institute of Chartered  Financial  Analysts and the  Washington
Society of Investment  Analysts.  Mr. Van Order joined  Calvert Group in October
1992 as the head of the trading desk. He oversees the day-to-day investments and
operations of the  department and  participates  in setting market and portfolio
strategy. Previously, Mr. Van Order was Director of Long Term Funding at Federal
National  Mortgage  Association  (Fannie Mae). In his former  capacity,  Mr. Van
Order was  responsible  for Fannie Mae's long term borrowing  programs,  hedging
programs and debt marketing program.

Calvert  Group  is  one  of  the  largest  investment  management  firms  in the
Washington, D.C. area.

Calvert Group,  Ltd., parent of the Funds' investment  advisor,  transfer agent,
and  distributor,  is a subsidiary  of Acacia Mutual Life  Insurance  Company of
Washington, D.C. Calvert Group is one of the largest investment management firms
in the  Washington,  D.C. area.  Calvert Group,  Ltd. and its  subsidiaries  are
located at 4550 Montgomery Avenue, Suite 1000N, Bethesda,  Maryland 20814. As of
December 31, 1994,  Calvert Group managed and  administered  assets in excess of
$4.2 billion and more than 200,000 shareholder and depositor accounts.

Calvert Asset Management serves as Advisor to the Funds. 

Calvert Asset Management Company,  Inc. (the "Advisor") is the Funds' investment
advisor.  The  Advisor  provides  the  Funds  with  investment  supervision  and
management;  administrative  services and office space;  furnishes executive and
other personnel to the Funds; and pays the salaries and fees of all Trustees who
are  affiliated  persons of the  Advisor.  The  Advisor  may also assume and pay
certain advertising and promotional expenses of the Funds and reserves the right
to compensate  broker-dealers  in return for their promotional or administrative
services.  The  Advisor  has  agreed to limit the  Funds'  expenses  to the most
restrictive state limitation in effect.

The Advisor receives a fee based on a percentage of each Fund's assets. 

For its services  during the fiscal year ended  September 30, 1994,  the Advisor
was  entitled  pursuant to the  Investment  Advisory  Agreement,  to receive the
following  investment  advisory  fees as a percentage  of the Funds'  respective
average  daily net assets:  Calvert U.S.  Government  Fund,  0.60%;  and Calvert
Income Fund, 0.70%.

Calvert Distributors, Inc. serves as underwriter to market the Fund's shares. 

Effective  March 1,  1995,  Calvert  Distributors,  Inc.  ("CDI")  is the Fund's
principal  underwriter  and  distributor.  Under the  terms of its  underwriting
agreement  with the Fund, CDI markets and  distributes  the Fund's shares and is
responsible  for  payment of  commissions  and service  fees to  broker-dealers,
banks,  and financial  services  firms,  preparation  of  advertising  and sales
literature,  and printing and mailing of prospectuses to prospective  investors.
Prior  to  March 1,  1995,  Calvert  Securities  Corporation  was the  principal
underwriter.

The transfer agent keeps your account records. 

Calvert Shareholder Services,  Inc. is the Funds' transfer,  dividend disbursing
and shareholder servicing agent.

Alternative Sales Options 

Each Fund offers two classes of shares: 

Class A Shares - Front End Load Option 

Class A shares are sold with a front-end  sales  charge at the time of purchase.
Class A shares are not subject to a sales charge when they are redeemed.

Class C shares - Level Load Option 

Class C shares  are sold  without  a sales  charge  at the time of  purchase  or
redemption.

Class C shares have higher expenses 

Each Fund bears some of the costs of selling its shares under Distribution Plans
adopted  with  respect to its Class A and Class C shares  pursuant to Rule 12b-1
under the 1940 Act.  Payments under the Class A Distribution Plan are limited to
a maximum of 0.50%  annually  of the  average  daily net asset  value of Class A
shares  for  Calvert  Income  Fund  (0.25%  for U.S.  Government).  The  Class C
Distribution Plan provides for the payment of an annual  distribution fee to CDI
of up to 0.75%,  plus a service fee of up to 0.25%,  for a total of 1.00% of the
average daily net assets attributable to their respective classes.

Considerations for deciding which class of shares to buy 

Income  distributions  for Class A shares will probably be higher than those for
Class C shares, as a result of the distribution  expenses  described above. (See
also "Total  Return.") You should  consider  Class A shares if you qualify for a
reduced sales charge under Class A or if you plan to hold the shares for several
years.

Class A Shares 

Class A shares are offered at net asset value plus a front-end  sales  charge as
follows:

*For new  investments  (new purchases but not exchanges) of $1 million or more a
broker-dealer will have the choice of being paid a finder's fee by CDI in one of
the following methods: (1) CDI may pay broker-dealer,  on a monthly basis for 12
months,  an annual rate of 0.30%.  Payments  will be made monthly at the rate of
0.025% of the amount of the  investment,  less  redemptions;  or (2) CDI may pay
broker-dealers  0.25% of the amount of the purchase;  however,  CDI reserves the
right to recoup any  portion of the  amount  paid to the dealer if the  investor
redeems  some or all of the shares from the Fund within  thirteen  months of the
time of purchase.
</TABLE>


Sales charges on Class A shares may be reduced or  eliminated in certain  cases.
See Exhibit A to this prospectus.

The sales charge is paid to CDI,  which in turn  normally  reallows a portion to
your  broker-dealer.  Upon  written  notice to  dealers  with whom it has dealer
agreements,  CDI may reallow up to the full applicable sales charge.  Dealers to
whom  substantially  the entire sales  charge is  reallowed  may be deemed to be
underwriters under the Securities Act of 1933.

In addition to any sales charge reallowance or finder's fee, your broker-dealer,
or other  financial  service firm through which your account is held,  currently
will be paid  periodic  service  fees at an  annual  rate of up to  0.25% of the
average  daily net asset value of Class A shares held in accounts  maintained by
that firm.

Class A Distribution Plan 

Each Fund has  adopted a  Distribution  Plan with  respect to its Class A shares
(the "Class A  Distribution  Plan"),  which  provides  for payments at a maximum
annual rate of 0.25% of the  average  daily net asset value of Class A shares of
U.S.  Government Fund (0.50% of Calvert Income Fund), to pay expenses associated
with the distribution and servicing of Class A shares.  Amounts paid by the Fund
to CDI  under  the  Class A  Distribution  Plan are used to pay to  dealers  and
others,  including CDI  salespersons  who service  accounts,  service fees at an
annual  rate of up to 0.25% of the  average  daily  net  asset  value of Class A
shares, and to pay CDI for its marketing and distribution  expenses,  including,
but not limited to,  preparation  of  advertising  and sales  literature and the
printing and mailing of prospectuses to prospective investors. During the fiscal
year ended September 30, 1994, Class A Distribution Plan expenses for the Income
and U.S. Government Funds were 0.06% and 0.09%, respectively.

Each of the  Distribution  Plans  may be  terminated  at any time by vote of the
Independent  Trustees or by vote of a majority of the outstanding  voting shares
of the respective class.

Class C Shares 

Class C shares are not available through all dealers. Class C shares are offered
at net asset value,  without a front-end  sales charge or a contingent  deferred
sales charge. Class C expenses are higher than those of Class A.

Class C Distribution Plan 

Each Fund has  adopted a  Distribution  Plan with  respect to its Class C shares
(the "Class C Distribution Plan"), which provides for payments at an annual rate
of up to 1.00% of the average  daily net asset  value of Class C shares,  to pay
expenses of the  distribution  and servicing of Class C shares.  Amounts paid by
the Fund under the Class C  Distribution  Plan are currently  used by CDI to pay
dealers and other selling firms dealer-paid quarterly  compensation at an annual
rate of up to 0.75%,  plus a service  fee, as  described  above  under  "Class A
Distribution Plan," of up to 0.25%, of the average daily net asset value of each
share sold by such others. For the fiscal year ended September 30, 1994, Class C
Distribution  Plan  expenses  were  1.00%  and  1.00%  for the  Income  and U.S.
Government Funds, respectively.

Arrangements with Broker-Dealers and Others 

CDI  may  also  pay  additional  concessions,   including  non-cash  promotional
incentives,  such as  merchandise  or trips,  to  dealers  employing  registered
representatives who have sold or are expected to sell a minimum dollar amount of
shares of the Fund and/or  shares of other Funds  underwritten  by CDI.  CDI may
make  expense  reimbursements  for  special  training  of a dealer's  registered
representatives,  advertising  or equipment,  or to defray the expenses of sales
contests.  Eligible marketing and distribution  expenses may be paid pursuant to
the Fund's Rule 12b-1 Distribution Plan.

Dealers or others may receive  different  levels of  compensation  depending  on
which class of shares they sell.  Payments  pursuant to a Distribution  Plan are
included in the operating expenses of the class.

NET ASSET VALUE 

Net asset  value  per share  ("NAV)"  refers to the worth of one  share.  NAV is
computed  by adding the value of all  portfolio  holdings,  plus  other  assets,
deducting  liabilities  and then  dividing  the  result by the  number of shares
outstanding.  The NAVs of each class will vary daily based on the market  values
of the Funds' respective investments.

Portfolio  securities  and other assets are valued  based on market  quotations,
except that securities  maturing within 60 days are valued at amortized cost. If
quotations are not  available,  securities are valued by a method that the Board
of Trustees believes accurately reflects fair value.

The NAV for each Fund is  calculated  at the close of the Fund's  business  day,
which  coincides  with the closing of the regular  session of the New York Stock
Exchange  (normally 4:00 p.m.  Eastern time). The Fund is open for business each
day the New York Stock  Exchange is open.  All  purchases of Fund shares will be
confirmed and credited to your account in full and fractional shares (rounded to
the nearest 1/1000 of a share).

WHEN YOUR ACCOUNT WILL BE CREDITED 

Before you buy shares,  please read the following  information to make sure your
investment is accepted and credited properly.

Your purchase will be processed at the next offering price based on the next net
asset  value  calculated  after your order is  received  and  accepted.  If your
purchase is received by 4:00 p.m. Eastern time, your account will be credited on
the day of receipt.  If your purchase is received after 4:00 p.m.  Eastern time,
it will be credited the next business  day. All  purchases  must be made in U.S.
dollars and checks must be drawn on U.S.  banks.  No cash will be accepted.  The
Fund  reserves  the right to suspend the offering of shares for a period of time
or to reject any specific  purchase  order.  If your check does not clear,  your
purchase will be cancelled and you will be charged a $10 fee plus costs incurred
by the Fund.  When you purchase by check or with Calvert Money  Controller,  the
Fund can hold payment on redemptions  until it is reasonably  satisfied that the
investment is collected  (normally 10 business  days).  To avoid this collection
period, you can wire federal funds from your bank, which may charge you a fee.

Certain financial institutions or broker-dealers which have entered into a sales
agreement with the Distributor may enter confirmed  purchase orders on behalf of
customers by phone,  with payment to follow within a number of days of the order
as specified by the program.  If payment is not received in the time  specified,
the financial institution could be held liable for resulting fees or losses.

EXCHANGES 

You may exchange shares of the Fund for shares of other Calvert Group Funds. 

If your investment goals change, the Calvert Group Family of Funds has a variety
of investment  alternatives  that includes  common stock funds,  tax-exempt  and
corporate  bond funds,  and money  market  funds.  The  exchange  privilege is a
convenient way to buy shares in other Calvert Group Funds in order to respond to
changes  in your  goals or in market  conditions.  However,  to protect a Fund's
performance and to minimize costs,  Calvert Group discourages frequent exchanges
and may prohibit  additional  purchases of Fund shares by persons engaged in too
many  short-term  trades.  Before you make an exchange from a Fund or Portfolio,
please note the following:

Call your broker or a Calvert  representative  for  information and a prospectus
for any of Calvert's other Funds  registered in your state.  Read the prospectus
of the  Fund  or  Portfolio  into  which  you  want  to  exchange  for  relevant
information, including class offerings.

Shares of a particular class of the Fund may be exchanged only for shares of the
same class of another  Calvert Fund,  except that any class may be exchanged for
Class A shares of any Calvert money market fund.

Each  exchange  represents  the sale of shares of one Fund and the  purchase  of
shares of another.  Therefore,  you could  realize a taxable gain or loss on the
transaction.

Complete  and sign an  application  for an  account  in that Fund or  Portfolio,
taking  care to  register  your  new  account  in the  same  name  and  taxpayer
identification number as your existing Calvert account(s). Exchange instructions
may then be given by telephone if telephone redemptions have been authorized and
the shares are not in certificate form.

Shares on which you have already paid a sales charge at Calvert Group and shares
acquired by  reinvestment  of dividends or  distributions  may be exchanged into
another Fund at no additional charge.

Shareholders (and those managing  multiple  accounts) who make two purchases and
two  exchange  redemptions  of shares of the same  Portfolio  during any 6-month
period  will be given  written  notice that they may be  prohibited  from making
additional  investments.  This  policy  does not  prohibit  a  shareholder  from
redeeming  shares of the Fund,  and does not apply to trades  solely among money
market funds.

The Fund reserves the right to terminate or modify the exchange  privilege  with
60 days' written notice.

OTHER CALVERT GROUP SERVICES 

Calvert Information Network 

24 hour yield and prices  

Calvert  Group  has a  round-the-clock  telephone  service  that  lets  existing
customers use a push button phone to obtain prices, yields and account balances.
Complete  instructions  for  this  service  may be  found  on the  back  of each
statement.

Calvert Money Controller 

Calvert Money Controller  eliminates the delay of mailing a check or the expense
of wiring funds. You can request this free service on your application.

This service allows you to authorize  electronic  transfers of money to purchase
or sell shares.  You use Calvert Money Controller like an "electronic  check" to
move money ($50 to $300,000)  between  your bank account and your Calvert  Group
account with one phone call.  Allow one or two business  days after the call for
the  transfer to take place;  for money  recently  invested,  allow normal check
clearing time (up to 10 business  days) before  redemption  proceeds are sent to
your bank.

You may also arrange systematic monthly or quarterly  investments  (minimum $50)
into your Calvert Group account.  After you give us proper  authorization,  your
bank account will be debited to purchase Fund shares.  A debit entry will appear
on your bank statement.  Share  purchases made through Calvert Money  Controller
will be  subject  to the  applicable  sales  charge.  If you would  like to make
arrangements for systematic  monthly or quarterly  redemptions from your Calvert
Group  account,  call  your  broker  or  Calvert  Group  for a Money  Controller
Application.

Telephone Transactions 

Calvert may record all telephone calls. 

If you have  telephone  transaction  privileges,  you may purchase,  redeem,  or
exchange shares,  wire funds and use Calvert Money Controller by telephone.  You
automatically  have telephone  privileges unless you elect otherwise.  The Fund,
the transfer agent and their  affiliates are not liable for acting in good faith
on  telephone  instructions  relating  to your  account,  so long as they follow
reasonable procedures to determine that the telephone  instructions are genuine.
Such  procedures  may include  recording the telephone  calls and requiring some
form of personal  identification.  You should  verify the  accuracy of telephone
transactions immediately upon receipt of your confirmation statement.

Optional Services 

Complete  the  "Option"  sections  of the  application  for the  easiest  way to
establish services.

The easiest way to establish  optional services on your Calvert Group account is
to select the options you desire when you complete your account application.  If
you wish to add other options later,  you may have to provide us with additional
information and a signature guarantee. Please call Calvert Investor Relations at
800-368-2745 for further assistance. For our mutual protection, we may require a
signature  guarantee  on  certain  written  transaction  requests.  A  signature
guarantee verifies the authenticity of your signature,  and may be obtained from
any  bank,   savings  and  loan  association,   credit  union,   trust  company,
broker-dealer firm or member of a domestic stock exchange. A signature guarantee
cannot be provided by a notary public.

Householding of General Mailings 

You can help in an effort to reduce Fund  expenses  and save paper and trees for
the environment.

If you have multiple accounts with Calvert, you may receive combined mailings of
some  shareholder  information,  such as semi-annual and annual reports.  Please
contact Calvert Investor  Relations at 800-368-2745 to receive additional copies
of information.

Special Services and Charges 

The Fund pays for  shareholder  services but not for special  services  that are
required by a few shareholders, such as a request for a historical transcript of
an  account.  You  may be  required  to pay a  research  fee for  these  special
services.

If you are purchasing  shares of the Fund through a program of services  offered
by a  broker-dealer  or  financial  institution,  you  should  read the  program
materials in conjunction with this Prospectus.  Certain features may be modified
in  these  programs,   and   administrative   charges  may  be  imposed  by  the
broker-dealer or financial institution for the services rendered.

Tax-Saving Retirement Plans 

Contact Calvert Group for complete  information  kits discussing the plans,  and
their benefits, provisions and fees.

Calvert Group can set up your new account under one of several tax-deferred
plans. These plans let you invest for retirement and shelter your
investment income from current taxes. Minimums may differ from those listed
in the chart on page _____. Also, reduced sales charges may apply. See
"Exhibit A - Reduced Sales Charges."

Individual retirement accounts (IRAs): available to anyone who has earned
income. You may also be able to make investments in the name of your
spouse, if your spouse has no earned income. Qualified Profit-Sharing and
Money-Purchase Plans (including 401(k) Plans): available to self-employed
people and their partners, or to corporations and their employees.

Simplified Employee Pension Plan (SEP-IRA): available to self-employed people
and their partners, or to corporations.  Salary reduction pension plans (SAR-SEP
IRAs) are also available to employers with 25 or fewer employees.

403(b)(7)  Custodial  Accounts:   available  to  employees  of  most  non-profit
organizations and public schools and universities.

SELLING YOUR SHARES 

You may redeem all or a portion of your shares on any business  day. Your shares
will be redeemed at the next net asset value  calculated  after your  redemption
request is received and accepted.  See the chart below for specific requirements
necessary to make sure your redemption request is acceptable.  Remember that the
Fund may hold payment on the  redemption  of your shares until it is  reasonably
satisfied that  investments  made by check or by Calvert Money  Controller  have
been collected (normally up to 10 business days).

Redemption Requirements To Remember 

To ensure  acceptance of your redemption  request,  please follow the procedures
described here and below.

Once your shares are redeemed,  the proceeds will normally be sent to you on the
next business day, but if making  immediate  payment could adversely  affect the
Fund,  it may take up to seven (7) days.  Calvert Money  Controller  redemptions
generally will be credited to your bank account on the first or second  business
day after your phone call.  When the New York Stock  Exchange is closed (or when
trading is  restricted)  for any  reason  other  than its  customary  weekend or
holiday  closings,  or under any  emergency  circumstances  as determined by the
Securities  and  Exchange  Commission,  redemptions  may be suspended or payment
dates postponed.

Minimum account balance is $1,000 per Fund. 

Please  maintain a balance  in your  account  of at least  $1,000 per Fund,  per
class.  If, due to redemptions,  the account falls below $1,000,  or you fail to
invest at least  $1,000,  your account may be closed and the proceeds  mailed to
you at the address of record. You will be given notice that your account will be
closed after 30 days unless you make an  additional  investment to increase your
account balance to the $1,000 minimum.

regular  checks for a fixed  amount sent to you on the 15th of each month simply
by sending a letter with all the information, including your account number, and
the dollar  amount ($100  minimum).  If you would like a regular check mailed to
another person or place, your letter must be signature-guaranteed.

Through your Broker 

If your  account  is held in your  broker's  name  ("street  name"),  you should
contact your broker directly to transfer, exchange or redeem shares.

DIVIDENDS, CAPITAL GAINS AND TAXES 

Each year, the Funds distribute substantially all of their net investment income
and capital gains to shareholders.

Dividends  from the Funds' net  investment  income  are  declared  and paid on a
monthly  basis.  Net  investment  income  consists of the interest  income,  net
short-term   capital  gains,  if  any,  and  dividends   declared  and  paid  on
investments,  less expenses.  Distributions of the Funds' net short-term capital
gains  (treated as dividends for tax  purposes)  and its net  long-term  capital
gains, if any, are normally declared and paid by the Fund once a year;  however,
the Fund does not  anticipate  making any such  distributions  unless  available
capital  loss  carryovers   have  been  used  or  have  expired.   Dividend  and
distribution payments will vary between classes; dividend payments are generally
anticipated to be higher for Class A shares.

Dividend and Distribution Payment Options. 

Dividends  and  any  distributions  are  automatically  reinvested  in the  same
Portfolio  at net asset  value (no sales  charge),  unless you elect to have the
dividends of $10 or more paid in cash (by check or by Calvert Money Controller).
Dividends and  distributions  may be  automatically  invested in an  identically
registered  account with the same account number in any other Calvert Group Fund
at net asset value.  If reinvested in the same Fund account,  new shares will be
purchased at net asset value on the reinvestment date, which is generally 1 to 3
days prior to the payment date. You must notify the Fund in writing prior to the
record  date to change  your  payment  options.  If you elect to have  dividends
and/or  distributions  paid in cash, and the U.S.  Postal Service cannot deliver
the  check,  or if it remains  uncashed  for six  months,  it, as well as future
dividends and distributions, will be reinvested in additional shares.

"Buying a Dividend" 

At the time of purchase,  the share price of the Fund may reflect  undistributed
income,  capital gains or unrealized  appreciation of securities.  Any income or
capital gains from these amounts  which are later  distributed  to you are fully
taxable.  On the  record  date for a  distribution,  the Fund's  share  value is
reduced by the amount of the  distribution.  If you buy shares  just  before the
record date ("buying a dividend") you will pay the full price for the shares and
then receive a portion of the price back as a taxable distribution.

Federal Taxes 

In January,  the Funds will mail you Form  1099-DIV  indicating  the federal tax
status of  dividends  and capital  gain  distributions  paid to you by the Funds
during the past year. Generally,  dividends and distributions are taxable in the
year they are paid. However, any dividends and distributions paid in January but
declared  during  the three  months  prior  are  taxable  in the year  declared.
Dividends and  distributions  are taxable to you  regardless of whether they are
taken in cash or reinvested.  Dividends, including short-term capital gains, are
taxable as ordinary  income.  Distributions  from  long-term  capital  gains are
taxable as long-term  capital gains,  regardless of how long you have owned Fund
shares.

You may realize a capital gain or loss when you sell or exchange shares. 

If you sell or  exchange  your Fund  shares  you will have a short or  long-term
capital  gain or loss,  depending  on how long you owned the  shares  which were
sold. In January, the Funds will mail you Form 1099-B indicating the date of and
proceeds  from all  sales,  including  exchanges.  You should  keep your  annual
year-end  account  statements  to  determine  the cost  (basis) of the shares to
report on your tax returns.

Other Tax Information 

In addition to federal taxes, you may be subject to state or local taxes on your
investment,  depending  on the laws in your area.  You will be  notified  to the
extent, if any, that dividends  reflect interest  received from U.S.  government
securities. Such dividends may be exempt from certain state income taxes.

Taxpayer Identification Number 

If we do not have your correct Social Security or Taxpayer Identification Number
("TIN") and a signed certified application or Form W-9, Federal law requires the
Funds to withhold 31% of your  dividends and certain  redemptions.  In addition,
you may be subject to a fine. You will also be prohibited  from opening  another
account by exchange.  If this TIN  information  is not  received  within 60 days
after your account is  established,  your account may be redeemed at the current
NAV on the date of  redemption.  The Funds  reserve  the right to reject any new
account or any purchase order for failure to supply a certified TIN.

EXHIBIT A 

REDUCED SALES CHARGES (CLASS A ONLY) 

You may  qualify for a reduced  sales  charge  through  several  purchase  plans
available. You must notify the Fund at the time of purchase to take advantage of
the reduced sales charge.

Right of Accumulation. The sales charge is calculated by taking into account not
only the dollar amount of a new purchase of shares,  but also the higher of cost
or current  value of shares  previously  purchased  in Calvert  Group Funds that
impose sales charges.  This  automatically  applies to your account for each new
purchase.

Letter of Intent.  If you plan to  purchase  $50,000 or more of Fund shares over
the next 13  months,  your  sales  charge  may be  reduced  through a "Letter of
Intent." You pay the lower sales charge  applicable to the total amount you plan
to invest over the 13-month  period,  excluding any money market fund purchases.
Part of your  shares  will be held in  escrow,  so that if you do not invest the
amount  indicated,  you will  have to pay the  sales  charge  applicable  to the
smaller  investment  actually made. For more  information,  see the Statement of
Additional Information.

Group  Purchases.  If you are a member of a qualified  group,  you may  purchase
shares of the Fund at the reduced sales charge  applicable to the group taken as
a whole.  The sales  charge is  calculated  by taking into  account not only the
dollar amount of the shares you purchase, but also the higher of cost or current
value of shares previously purchased and currently held by other members of your
group.

A  "qualified  group" is one which (i) has been in  existence  for more than six
months,  (ii) has a purpose other than acquiring Fund shares at a discount,  and
(iii)  satisfies  uniform  criteria  which enable CDI and dealers  offering Fund
shares to realize  economies of scale in distributing  such shares.  A qualified
group must have more than 10  members,  must be  available  to arrange for group
meetings  between  representatives  of CDI or  dealers  distributing  the Fund's
shares,  must agree to include sales and other materials  related to the Fund in
its  publications  and  mailings  to  members  at  reduced  or no cost to CDI or
dealers,  and  must  seek  to  arrange  for  payroll  deduction  or  other  bulk
transmission of investments to the Fund.

Pension plans may not qualify  participants for group purchases;  however,  such
plans may qualify for reduced  sales  charges  under a separate  provision  (see
below). Members of a group are not eligible for a Letter of Intent.

Retirement Plans Under Section 457, Section 403(b)(7),  or Section 401(k). There
is no sales  charge on shares  purchased  for the benefit of a  retirement  plan
under Section 457 of the Internal Revenue Code of 1986, as amended ("Code"),  or
for a plan  qualifying  under  Section  403(b)(7) of the Code if, at the time of
purchase, Calvert Group has been notified in writing that the 403(b)(7) plan has
at least 200 eligible employees. Furthermore, there is no sales charge on shares
purchased for the benefit of a retirement plan  qualifying  under Section 401(k)
of the Code if, at the time of such purchase,  the 401(k) plan administrator has
notified  Calvert  Group in  writing  that a) its  401(k)  plan has at least 200
eligible  employees;  or b) the cost or current  value of shares the plan has in
Calvert Group of Funds (except money market funds) is at least $1 million.

Neither the Fund,  nor CDI, nor any affiliate  thereof will  reimburse a plan or
participant  for any  sales  charges  paid  prior  to  receipt  of such  written
communication and confirmation by Calvert Group. Plan administrators should send
requests  for the  waiver of sales  charges  based on the above  conditions  to:
Calvert Group Retirement Plans, 4550 Montgomery Avenue,  Suite 1000N,  Bethesda,
Maryland 20814.

Other  Circumstances.  There is no sales charge on shares of any fund (portfolio
or series) of the Calvert Group of Funds sold to (i) current and retired members
of the Board of  Trustees/Directors  of the  Calvert  Group of  Funds,  (and the
Advisory  Council  of the  Calvert  Social  Investment  Fund);  (ii)  directors,
officers  and  employees  of the  Advisor,  Distributor,  and  their  affiliated
companies;  (iii) directors,  officers and registered representatives of brokers
distributing  the Fund's shares;  and immediate family members of persons listed
in (i), (ii), and (iii), above; (iv) dealers,  brokers, or registered investment
advisors that have entered into an agreement with CDI providing specifically for
the use of shares of the Fund  (Portfolio  or Series) in  particular  investment
programs or products  (where such  program or product  already has a fee charged
therein)  made  available to the clients of such dealer,  broker,  or registered
investment advisor;  and (v) trust departments of banks or savings  institutions
for trust clients of such bank or savings institution.

Established  Accounts.  Shares of Calvert  Income  Fund may be sold at net asset
value to accounts opened on or before January 12, 1987.

Dividends and Capital Gain Distributions from other Calvert Group Funds. You may
prearrange to have your  dividends and capital gain  distributions  from another
Calvert Group Fund automatically  invested in another account with no additional
sales charge.  Dividends and distributions from Calvert Group money market funds
used to purchase shares of the Fund will not be subject to the applicable  sales
charge, effective April 1, 1995.

Reinstatement  Privilege.  If you redeem  Fund  shares  and then  within 30 days
decide to reinvest  in the same Fund,  you may do so at the net asset value next
computed after the reinvestment  order is received,  without a sales charge. You
may use the  reinstatement  privilege  only once. The Fund reserves the right to
modify or eliminate this privilege.

Redemptions  From Other Mutual Funds. You may purchase shares of the above funds
at net asset  value,  without  sales  charge,  to the extent  that the  purchase
represents proceeds from a redemption (within the previous 60 days) of shares of
another  mutual  fund.  When  making a purchase  at net asset  value  under this
provision,  the Fund or Portfolio  must receive one of the  following  with your
direct purchase order: (i) the redemption check representing the proceeds of the
shares redeemed,  endorsed to the order of the Fund or Portfolio, or (ii) a copy
of the  confirmation  from the other fund,  showing the redemption  transaction.
Standard  back office  procedures  should be followed for wire order  purchases.
Purchases  with  redemptions  from money  market funds are not eligible for this
privilege.  This provision is effective  through March 15, 1995 only, but may be
extended at the discretion of the Distributor.

THE CALVERT FUND 
CALVERT INCOME FUND 
4550 Montgomery Avenue, Bethesda, Maryland 20814 

INVESTMENT  OBJECTIVE Calvert Income Fund seeks to maximize long-term income, to
the extent  consistent with prudent  investment  management and  preservation of
capital, through investment in bonds and other income producing securities.

The Fund offers two classes of shares,  each with  different  expense levels and
sales  charges.  You may  choose to  purchase  (i) Class A shares,  with a sales
charge imposed at the time you purchase the shares  ("front-end  sales charge");
or (ii) Class C shares  which  impose  neither a  front-end  sales  charge nor a
contingent  deferred sales charge.  Class C shares are not available through all
dealers.  Class C shares have a higher  level of  expenses  than Class A shares,
including  higher Rule 12b-1 fees. These  alternatives  permit you to choose the
method of purchasing  shares that is most  beneficial  to you,  depending on the
amount of the  purchase,  the length of time you expect to hold the shares,  and
other circumstances. See "Alternative Sales Options" for further details.

TO OPEN AN ACCOUNT Call your broker, or complete and return the enclosed Account
Application. Minimum investment is $2,000.

Explanation of Table: The purpose of the table is to assist you in understanding
the various  costs and expenses  that an investor in the Fund may bear  directly
(shareholder transaction costs) or indirectly (annual fund operating expenses).

A. Shareholder Transaction Costs are charges you pay when you buy or sell shares
of the Fund.  See "Reduced Sales Charges" at Exhibit A to see if you qualify for
possible  reductions  in the sales charge.  If you request a wire  redemption of
less than $1,000, you will be charged a $5 wire fee.

B.  Annual  Fund  Operating  Expenses.  Management  Fees are paid by the Fund to
Calvert Asset Management Company, Inc.  ("Investment  Advisor") for managing the
Fund's  investments  and business  affairs.  The Fund incurs Other  Expenses for
maintaining shareholder records,  furnishing shareholder statements and reports,
and  other  services.  Management  Fees and Other  Expenses  have  already  been
reflected in the Fund's share price and are not charged  directly to  individual
shareholder  accounts.  Please  refer to  "Management  of the Fund" for  further
information.

The Fund's Rule 12b-1 fees include an  asset-based  sales  charge.  Thus,  it is
possible  that  long-term  shareholders  in the Fund may pay more in total sales
charges  than the  economic  equivalent  of the maximum  front-end  sales charge
permitted by rules of the National Association of Securities Dealers, Inc.

C.  Example of  Expenses.  The  example,  which is  hypothetical,  should not be
considered a  representation  of past or future  expenses.  Actual  expenses and
return may be higher or lower than those shown.

================================================================================

INVESTMENT OBJECTIVE AND POLICIES 

Calvert  Income Fund  invests in a variety of  fixed-income  securities,  65% of
which must be of investment grade quality.

Calvert Income Fund seeks to maximize long-term income, to the extent consistent
with  prudent  investment  management  and  preservation  of capital,  primarily
through  investment  in  investment  grade  bonds  and  other   income-producing
securities.  The  Fund is  nondiversified.  Debt  securities  may be  long-term,
intermediate-term,  short-term,  or any  combination  thereof,  depending on the
Advisor's evaluation of current and anticipated market patterns and trends.

Calvert Income Fund invests 80% of its assets in corporate obligations and other
fixed-income  securities.  At least 65% of its assets at the date of  investment
are rated  within the four  highest  grades  established  by  Moody's  Investors
Services, Inc. (Aaa, Aa, A, or Baa), or by Standard and Poor's Corporation (AAA,
AA, A, or BBB), or if not rated, are of comparable  quality as determined by the
Advisor. Though still investment grade, securities rated BBB/Baa possess certain
speculative  elements and are  generally  more  susceptible  to changing  market
conditions. All fixed income instruments are subject to interest-rate risk; that
is, when market interest rates rise, the current  principal value of a bond will
decline.

The  remaining  35% of the  Fund's  total  assets  may  consist  of  other  debt
securities (see below)  including bonds rated below BBB or Baa  ("non-investment
grade  securities,"  commonly  known as "junk  bonds").  With lower rated bonds,
there is a greater possibility that an adverse change in the financial condition
of the issuer may affect its ability to pay principal and interest. In addition,
to the extent the Fund holds any such bonds,  it may be  negatively  affected by
adverse economic developments,  increased volatility or a lack of liquidity. See
the Statement of Additional Information, "Non-Investment Grade Debt Securities,"
and bond ratings.

Calvert  Income Fund may also  purchase  obligations  issued or guaranteed as to
principal  by  the  U.S.  Government  or  its  agencies  or   instrumentalities;
certificates of deposit,  time deposits,  and bankers' acceptances of U.S. banks
and their branches  located outside of the U.S. and of U.S.  branches of foreign
banks,  provided that the bank has total assets of at least one billion  dollars
or the  equivalent in other  currencies;  commercial  paper which at the date of
investment  is rated  Prime-2 or better by Moody's,  A-2 or better by Standard &
Poor's, or, if not rated, is of comparable quality as determined by the Advisor;
and any of the above securities subject to repurchase agreements with recognized
securities  dealers and banks. Up to 20% of the value of the Fund's total assets
may consist of other debt securities (including  securities  convertible into or
carrying  warrants to purchase  common  stock or other  equity  securities)  and
income-producing preferred and common stocks.

GNMA Certificates 

GNMA  Certificates,   or  GNMAs,  are  mortgage-backed  securities  representing
ownership of mortgage or  construction  loans that are issued by lenders such as
mortgage  bankers,  commercial  banks and savings and loan  associations and are
either  insured by the  Federal  Housing  Administration  or  guaranteed  by the
Veterans Housing  Administration.  The GNMA may be secured by a single mortgage,
such as a large  multi-family  housing  development,  or, more  typically,  by a
"pool" or group of single-family housing mortgages.

Once  approved by GNMA,  the timely  payment of interest  and  principal on each
mortgage  is  guaranteed  by GNMA and backed by the full faith and credit of the
U.S. Government.  GNMAs differ from bonds in that principal is paid back monthly
by the borrower  over the term of the loan rather than returned in a lump sum at
maturity.  GNMAs are called "pass-through"  securities because both interest and
principal payments  (including  prepayments) are passed through to the holder of
the GNMA.  Upon  receipt,  principal  payments will be reinvested by the Fund in
additional  securities at the then  prevailing  interest rate. The amount of any
premium that may be paid upon purchase of a GNMA is not guaranteed.  The Advisor
will attempt, through careful evaluation of available GNMA issues and prevailing
market conditions, to invest in GNMAs which provide a high income return but are
not subject to substantial risk of loss of principal.  Accordingly,  the Advisor
may forgo the  opportunity  to invest in  certain  issues of GNMAs  which  would
provide a high  current  income yield if the Advisor  believes  that such issues
would be subject to a risk of prepayment or loss of principal over the long-term
that would outweigh the short-term increment in yield.

Collateralized Mortgage Obligations 

Collateralized  mortgage  obligations  ("CMOs")  are bonds which are the general
obligations  of the bond issuer.  CMOs may be issued by  governmental  entities,
such  as  the  Federal  Home  Loan   Mortgage   Corporation   (FHLMC),   and  by
non-governmental  entities,  such as banks  and  other  mortgage  lenders.  CMOs
generally are secured by collateral consisting of individual mortgages or a pool
of mortgages. CMOs are not direct obligations of the Government.

FNMA and FHLMC Certificates 

Each Fund may invest in pass-through certificates issued by the Federal National
Mortgage  Association  ("FNMA")  and  Federal  Home  Loan  Mortgage  Corporation
("FHLMC").  Unlike GNMAs,  which are  typically  interests in pools of mortgages
insured  or  guaranteed  by  government  agencies,  FNMA and FHLMC  certificates
represent undivided interests in pools of conventional mortgage loans.

Nondiversified 

There may be risks associated with the Fund being nondiversified. Specificially,
since a relatively  high percentage of the assets of the Fund may be invested in
the  obligations of a limited number of issuers,  the value of the shares of the
Fund may be more  susceptible  to any single  economic,  political or regulatory
event than the shares of a diversified fund would be.

Financial Futures, Options, and Other Investment Techniques 

The Fund can use various  techniques  to increase  or decrease  its  exposure to
changing  security  prices,  interest  rates,  currency  exchange rates or other
factors that affect security  values.  These  techniques may involve  derivative
transactions  such as buying and  selling  options  and  futures  contracts  and
leveraged notes, entering into currency exchange contracts,  or swap agreements,
and purchasing  indexed  securities.  The Fund can use these practices either as
substitution or as protection against an adverse move in the Fund's portfolio to
adjust  the risk and return  characteristics  of the  Fund's  portfolio.  If the
Advisor judges market conditions incorrectly or employs a strategy that does not
correlate  well  with the  Fund's  investments,  or if the  counterparty  to the
transaction  does not perform as promised,  these  techniques  could result in a
loss. These techniques may increase the volatility of the Fund and may involve a
small  investment of cash  relative to the  magnitude of the risk  assumed.  Any
instruments  determined to be illiquid are subject to the Fund's 15% restriction
on illiquid  securities.  See the Statement of Additional  Information  for more
detail about these strategies.

The Fund may enter into repurchase  agreements and may purchase  securities on a
forward or when-issued basis.

In a  repurchase  agreement,  the Fund buys a security  subject to the right and
obligation to sell it back at a higher price.  These  transactions must be fully
secured at all times, but they involve some credit risk to the Fund if the other
party  defaults  on its  obligation  and the Fund is delayed or  prevented  from
liquidating the collateral.

Purchasing  obligations  for future  delivery  or on a  "when-issued"  basis may
increase the Fund's overall  investment  exposure and involves a risk of loss if
the  value  of the  securities  declines  prior  to  the  settlement  date.  The
transactions are fully secured at all times.

Foreign Investments 

The Fund may invest up to 20% of its assets in  securities  of foreign  issuers,
and hedge its foreign securities  holdings against  anticipated adverse moves in
foreign  currency  exchange  rates.  The Fund  may use  either  the spot  (cash)
markets,   forward   contracts,   or  currency  financial  futures  and  options
transactions.  It is impossible to forecast with precision the foreign  currency
values,  and the Fund could incur a loss on such  currency  transactions  if the
market moves against the position it has taken.  Securities  of foreign  issuers
may  offer  greater  potential  for  capital  appreciation  or  income  than the
securities of domestic issuers and may involve investment risks that are greater
than those  inherent in the  securities of domestic  issuers.  Such  differences
might  possibly  result  from  future   political  and  economic   developments,
disparities  in  economic  systems,   and  imposition  of  foreign  governmental
restrictions.  There may also be less  publicly  available  information  about a
foreign issuer than about a domestic  issuer;  foreign issuers are not generally
subject to uniform auditing, accounting and reporting requirements comparable to
those applicable to domestic issuers.

Other Policies 

The Fund may borrow money from banks as a temporary measure for extraordinary or
emergency  purposes.  An explanation of this and the policies below is set forth
in the Statement of Additional Information.

The Fund may lend its portfolio securities to member firms of the New York Stock
Exchange and commercial banks with assets of $1 billion or more, but only if the
value of the  securities  loaned  from a Fund will not exceed  one-third  of the
Fund's assets.

The Fund has  adopted  certain  fundamental  investment  restrictions  which are
discussed  in  detail  in  the  Statement  of  Additional  Information.   Unless
specifically   noted   otherwise,   the  investment   objective,   policies  and
restrictions  of the  Fund  are  fundamental  and  may  not be  changed  without
shareholder approval.

Although  U.S.  Government-backed  obligations  in the Fund's  portfolio  may be
guaranteed by the Government, the Fund's net asset value per share and yield are
not guaranteed and will change in response to market conditions. There can be no
assurance that the Fund will be successful in meeting its investment objective.

YIELD AND TOTAL RETURN 

The Fund may advertise yield and total return for each class. 

Yield measures the current  investment  performance  for each class of the Fund,
that is, the rate of income on its  portfolio  investments  divided by the share
price.  Yield  is  computed  by  annualizing  the  result  of  dividing  the net
investment  income per share over a 30-day period by the maximum  offering price
per share on the last day of that  period.  Yields are  calculated  according to
accounting methods that are standardized for all stock and bond funds.

Both yield and total return are based on historical results and are not intended
to indicate future performance.

Total return is calculated  separately for each class.  It includes not only the
effect of income  dividends but also any change in net asset value, or principal
amount,  during the stated period. The total return of a class shows its overall
change in value, including changes in share price and assuming all of the class'
dividends and capital gain  distributions  are  reinvested.  A cumulative  total
return reflects the class'  performance over a stated period of time. An average
annual total return  reflects the  hypothetical  annual  compounded  return that
would have produced the same cumulative total return if the performance had been
constant over the entire period.  Because  average annual returns tend to smooth
out variations in the returns,  you should  recognize that they are not the same
as actual year-by-year  results. Both types of total return usually will include
the effect of paying the front-end sales charge,  in the case of Class A shares.
Of course,  total  returns  will be higher if sales  charges  are not taken into
account.  Quotations of "overall  return" do not reflect  deduction of the sales
charge.  You should  consider  overall  return figures only if you qualify for a
reduced sales  charge,  or for purposes of comparison  with  comparable  figures
which also do not reflect sales charges,  such as mutual fund averages  compiled
by Lipper  Analytical  Services,  Inc.  Further  information  about  the  Fund's
performance  is contained  in its Annual  Report to  Shareholders,  which may be
obtained without charge.

MANAGEMENT OF THE FUND 

The Trust's Board of Trustees  supervises the Trust's activities and reviews its
contracts with companies that provide it with services.

Calvert Income Fund is a series of The Calvert Fund (the  "Trust"),  an open-end
management  investment  company  organized as a Massachusetts  business trust on
March 15, 1982. The other series of the Fund are Calvert  Strategic  Growth Fund
and Calvert U.S. Government Fund.

The Trust is not  required  to hold  annual  shareholder  meetings,  but special
meetings may be called for certain purposes such as electing Trustees,  changing
fundamental policies, or approving a management contract. As a shareholder,  you
receive one vote for each share of the Fund you own. Matters  affecting  classes
differently,  such as  Distribution  Plans,  will be voted on  separately by the
affected class(es).

Portfolio Managers 

Investment  selections for the Fund are made by Colleen M. Denzler,  C.F.A., and
Stephen N. Van Order.  Ms.  Denzler has been with the Calvert  Group since 1986,
and has been a member of the Portfolio Investment Department since January 1987.
She is a  member  of the  Institute  of  Chartered  Financial  Analysts  and the
Washington Society of Investment Analysts. Mr. Van Order joined Calvert Group in
October  1992 as the  head of the  trading  desk.  He  oversees  the  day-to-day
investments and operations of the department and  participates in setting market
and  portfolio  strategy.  Previously,  Mr. Van Order was  Director of Long Term
Funding at Federal  National  Mortgage  Association  (Fannie Mae). In his former
capacity,  Mr. Van Order was  responsible  for Fannie Mae's long term  borrowing
programs,  hedging  programs and debt marketing  program.  Both have managed the
Fund since early 1995.

Calvert  Group  is  one  of  the  largest  investment  management  firms  in the
Washington, D.C. area.

Calvert Group,  Ltd., parent of the Fund's investment  advisor,  transfer agent,
and  distributor,  is a subsidiary  of Acacia Mutual Life  Insurance  Company of
Washington, D.C. Calvert Group is one of the largest investment management firms
in the  Washington,  D.C. area.  Calvert Group,  Ltd. and its  subsidiaries  are
located at 4550 Montgomery Avenue, Suite 1000N, Bethesda,  Maryland 20814. As of
December 31, 1994,  Calvert Group managed and  administered  assets in excess of
$4.2 billion and more than 200,000 shareholder and depositor accounts.

Calvert Asset Management serves as Advisor to the Fund. 

Calvert Asset Management Company,  Inc. (the "Advisor") is the Fund's investment
advisor.  The  Advisor  provides  the  Fund  with  investment   supervision  and
management;  administrative  services and office space;  furnishes executive and
other  personnel to the Fund; and pays the salaries and fees of all Trustees who
are  affiliated  persons of the  Advisor.  The  Advisor  may also assume and pay
certain advertising and promotional  expenses of the Fund and reserves the right
to compensate  broker-dealers  in return for their promotional or administrative
services.  The  Advisor  has  agreed to limit the  Fund's  expenses  to the most
restrictive state limitation in effect.

The Advisor receives a fee based on a percentage of the Fund's assets. 

For its services  during the fiscal year ended  September 30, 1994,  the Advisor
was  entitled  pursuant  to the  Investment  Advisory  Agreement,  to receive an
investment  advisory  fee of 0.70% of the Fund's  respective  average  daily net
assets.

Calvert Distributors, Inc. serves as underwriter to market the Fund's shares. 

Calvert  Distributors,  Inc.  ("CDI") is the Fund's  principal  underwriter  and
distributor.  Under the terms of its  underwriting  agreement with the Fund, CDI
markets and  distributes  the Fund's  shares and is  responsible  for payment of
commissions and service fees to  broker-dealers,  banks, and financial  services
firms, preparation of advertising and sales literature, and printing and mailing
of prospectuses to prospective investors.

The transfer agent keeps your account records. 

Calvert Shareholder Services,  Inc. is the Fund's transfer,  dividend disbursing
and shareholder servicing agent.

Alternative Sales Options 

The Fund offers two classes of shares: 

Class A Shares - Front End Load Option 

Class A shares are sold with a front-end  sales  charge at the time of purchase.
Class A shares are not subject to a sales charge when they are redeemed.

Class C shares - Level Load Option 

Class C shares  are sold  without  a sales  charge  at the time of  purchase  or
redemption.

Class C shares have higher expenses 

The Fund bears some of the costs of selling its shares under  Distribution Plans
adopted  with  respect to its Class A and Class C shares  pursuant to Rule 12b-1
under the 1940 Act.  Payments under the Class A Distribution Plan are limited to
a maximum of 0.50% annually of the average daily net asset value of Class A. The
Class C Distribution Plan provides for the payment of an annual distribution fee
to CDI of up to 0.75%,  plus a service fee of up to 0.25%,  for a total of 1.00%
of the  average  daily net  assets  attributable  to their  respective  classes.

Considerations for deciding which class of shares to buy

Income  distributions  for Class A shares will probably be higher than those for
Class C shares, as a result of the distribution  expenses  described above. (See
also "Total  Return.") You should  consider  Class A shares if you qualify for a
reduced sales charge under Class A or if you plan to hold the shares for several
years.

Class A Shares 

Class A shares are offered at net asset value plus a front-end  sales  charge as
follows:

                                                                 Concession to
                                                  As a % of Net  Dealers as a %
                                   As a % of     Amount Invested   of Amount  
Amount of Investment              Offering Price                   Invested 

- --------------------------------------------------------------------------------
- --------------------------------------------------------------------------------
Less than $50,000                   3.75%             3.90%         3.00% 
$50,000 but less than $100,000      3.00%             3.09%         2.25% 
$100,000 but less than $250,000     2.25%             2.30%         1.75% 
$250,000 but less than $500,000     1.75%             1.78%         1.25% 
$500,000 but less than $1,000,000   1.00%             1.01%         0.80% 
$1,000,000 and over                 0.00%             0.00%         0.25%* 


*For new  investments  (new purchases but not exchanges) of $1 million or more a
broker-dealer will have the choice of being paid a finder's fee by CDI in one of
the following methods:  (1) CDI may pay a broker-dealer,  on a monthly basis for
12 months, an annual rate of 0.30%. Payments will be made monthly at the rate of
0.025% of the amount of the investment,  less redemptions;  or (2) CDI may pay a
broker-dealer  0.25% of the amount of the  purchase;  however,  CDI reserves the
right to recoup any  portion of the  amount  paid to the dealer if the  investor
redeems  some or all of the shares from the Fund within  thirteen  months of the
time of purchase.

Sales charges on Class A shares may be reduced or  eliminated in certain  cases.
See Exhibit A to this prospectus.

The sales charge is paid to CDI,  which in turn  normally  reallows a portion to
your  broker-dealer.  Upon  written  notice to  dealers  with whom it has dealer
agreements,  CDI may reallow up to the full applicable sales charge.  Dealers to
whom 90% or more of the entire  sales  charge is  reallowed  may be deemed to be
underwriters under the Securities Act of 1933.

In addition to any sales charge reallowance or finder's fee, your broker-dealer,
or other  financial  service firm through which your account is held,  currently
will be paid  periodic  service  fees at an  annual  rate of up to  0.25% of the
average  daily net asset value of Class A shares held in accounts  maintained by
that firm.

Class A Distribution Plan 

The Fund has adopted a Distribution Plan with respect to its Class A shares (the
"Class A  Distribution  Plan"),  which provides for payments at a maximum annual
rate of 0.50% of the average  daily net asset value of the Fund's Class A shares
to pay expenses associated with the distribution and servicing.  Amounts paid by
the Fund to CDI under the Class A  Distribution  Plan are used to pay to dealers
and others, including CDI salespersons who service accounts,  service fees at an
annual  rate of up to 0.25% of the  average  daily  net  asset  value of Class A
shares, and to pay CDI for its marketing and distribution  expenses,  including,
but not limited to,  preparation  of  advertising  and sales  literature and the
printing and mailing of prospectuses to prospective investors. During the fiscal
year ended September 30, 1994,  Class A Distribution  Plan expenses for the Fund
were 0.06%.

Each of the  Distribution  Plans  may be  terminated  at any time by vote of the
Independent  Trustees or by vote of a majority of the outstanding  voting shares
of the respective class.

Class C Shares 

Class C shares are not available through all dealers. Class C shares are offered
at net asset value,  without a front-end  sales charge or a contingent  deferred
sales charge. Class C expenses are higher than those of Class A.

Class C Distribution Plan 

The Fund has adopted a Distribution Plan with respect to its Class C shares (the
"Class C Distribution  Plan"),  which provides for payments at an annual rate of
up to 1.00% of the  average  daily  net asset  value of Class C  shares,  to pay
expenses of the  distribution  and servicing of Class C shares.  Amounts paid by
the Fund under the Class C  Distribution  Plan are currently  used by CDI to pay
dealers and other selling firms  quarterly  compensation at an annual rate of up
to 0.75%,  plus a service  fee, as described  above under "Class A  Distribution
Plan," of up to 0.25%,  of the average  daily net asset value of each share sold
by  such  others.  For  the  fiscal  year  ended  September  30,  1994,  Class C
Distribution Plan expenses were 1.00% for the Fund.

Arrangements with Broker-Dealers and Others 

CDI  may  also  pay  additional  concessions,   including  non-cash  promotional
incentives,  such as  merchandise  or trips,  to  dealers  employing  registered
representatives who have sold or are expected to sell a minimum dollar amount of
shares of the Fund and/or  shares of other Funds  underwritten  by CDI.  CDI may
make  expense  reimbursements  for  special  training  of a dealer's  registered
representatives,  advertising  or equipment,  or to defray the expenses of sales
contests.  Eligible marketing and distribution  expenses may be paid pursuant to
the Fund's Rule 12b-1 Distribution Plan.

Dealers or others may receive  different  levels of  compensation  depending  on
which class of shares they sell.  Payments  pursuant to a Distribution  Plan are
included in the operating expenses of the class.

*Please allow  sufficient time for Calvert Group to process your initial request
for this service,  normally 10 business days. The maximum  transaction amount is
$300,000, and your purchase request must be received by 4:00 p.m. Eastern time.

NET ASSET VALUE 

Net asset  value  per share  ("NAV)"  refers to the worth of one  share.  NAV is
computed  by adding the value of all  portfolio  holdings,  plus  other  assets,
deducting  liabilities  and then  dividing  the  result by the  number of shares
outstanding.  The NAVs of each class will vary daily based on the market  values
of the Fund's investments.

Portfolio  securities  and other assets are valued  based on market  quotations,
except that securities  maturing within 60 days are valued at amortized cost. If
quotations are not  available,  securities are valued by a method that the Board
of Trustees believes accurately reflects fair value.

The NAV for the Fund is  calculated  at the close of the  Fund's  business  day,
which  coincides  with the closing of the regular  session of the New York Stock
Exchange  (normally 4:00 p.m.  Eastern time). The Fund is open for business each
day the New York Stock  Exchange is open.  All  purchases of Fund shares will be
confirmed and credited to your account in full and fractional shares (rounded to
the nearest 1/1000 of a share).

WHEN YOUR ACCOUNT WILL BE CREDITED 

Before you buy shares,  please read the following  information to make sure your
investment is accepted and credited properly.

Your purchase will be processed at the next offering price based on the next net
asset  value  calculated  after your order is  received  and  accepted.  If your
purchase is received by 4:00 p.m. Eastern time, your account will be credited on
the day of receipt.  If your purchase is received after 4:00 p.m.  Eastern time,
it will be credited the next business  day. All  purchases  must be made in U.S.
dollars and checks must be drawn on U.S.  banks.  No cash will be accepted.  The
Fund  reserves  the right to suspend the offering of shares for a period of time
or to reject any specific  purchase  order.  If your check does not clear,  your
purchase will be cancelled and you will be charged a $10 fee plus costs incurred
by the Fund.  When you purchase by check or with Calvert Money  Controller,  the
Fund can hold payment on redemptions  until it is reasonably  satisfied that the
investment is collected  (normally 10 business  days).  To avoid this collection
period, you can wire federal funds from your bank, which may charge you a fee.

Certain financial institutions or broker-dealers which have entered into a sales
agreement with the Distributor may enter confirmed  purchase orders on behalf of
customers by phone,  with payment to follow within a number of days of the order
as specified by the program.  If payment is not received in the time  specified,
the financial institution could be held liable for resulting fees or losses.

EXCHANGES 

You may exchange shares of the Fund for shares of other Calvert Group Funds. 

If your investment goals change, the Calvert Group Family of Funds has a variety
of investment  alternatives  that includes  common stock funds,  tax-exempt  and
corporate  bond funds,  and money  market  funds.  The  exchange  privilege is a
convenient way to buy shares in other Calvert Group Funds in order to respond to
changes  in your  goals or in market  conditions.  However,  to protect a Fund's
performance and to minimize costs,  Calvert Group discourages frequent exchanges
and may prohibit  additional  purchases of Fund shares by persons engaged in too
many  short-term  trades.  Before you make an exchange from a Fund or Portfolio,
please note the following:

Call your broker or a Calvert  representative  for  information and a prospectus
for any of Calvert's other Funds  registered in your state.  Read the prospectus
of the  Fund  or  Portfolio  into  which  you  want  to  exchange  for  relevant
information, including class offerings.

Each  exchange  represents  the sale of shares of one Fund and the  purchase  of
shares of another.  Therefore,  you could  realize a taxable gain or loss on the
transaction.

Complete  and sign an  application  for an  account  in that Fund or  Portfolio,
taking  care to  register  your  new  account  in the  same  name  and  taxpayer
identification number as your existing Calvert account(s). Exchange instructions
may then be given by telephone if telephone redemptions have been authorized and
the shares are not in certificate form.

Shares on which you have already paid a sales charge at Calvert Group and shares
acquired by  reinvestment  of dividends or  distributions  may be exchanged into
another Fund at no additional charge.

Shareholders (and those managing  multiple  accounts) who make two purchases and
two  exchange  redemptions  of shares of the same  Portfolio  during any 6-month
period  will be given  written  notice that they may be  prohibited  from making
additional  investments.  This  policy  does not  prohibit  a  shareholder  from
redeeming  shares of the Fund,  and does not apply to trades  solely among money
market funds.

The Fund reserves the right to terminate or modify the exchange  privilege  with
60 days' written notice.

OTHER CALVERT GROUP SERVICES 

Calvert Information Network 

24 hour yield and prices  

Calvert  Group  has a  round-the-clock  telephone  service  that  lets  existing
customers  use a push button phone to obtain  prices,  performance  information,
account balances, and authorize certain transactions.

Calvert Money Controller 

Calvert Money Controller  eliminates the delay of mailing a check or the expense
of wiring funds. You can request this free service on your application.

This service allows you to authorize  electronic  transfers of money to purchase
or sell shares.  You use Calvert Money Controller like an "electronic  check" to
move money ($50 to $300,000)  between  your bank account and your Calvert  Group
account with one phone call.  Allow one or two business  days after the call for
the  transfer to take place;  for money  recently  invested,  allow normal check
clearing time (up to 10 business  days) before  redemption  proceeds are sent to
your bank.

You may also arrange systematic monthly or quarterly  investments  (minimum $50)
into your Calvert Group account.  After you give us proper  authorization,  your
bank account will be debited to purchase Fund shares.  A debit entry will appear
on your bank statement.  Share  purchases made through Calvert Money  Controller
will be  subject  to the  applicable  sales  charge.  If you would  like to make
arrangements for systematic  monthly or quarterly  redemptions from your Calvert
Group  account,  call  your  broker  or  Calvert  Group  for a Money  Controller
Application.

Telephone Transactions 

Calvert may record all telephone calls. 

If you have  telephone  transaction  privileges,  you may purchase,  redeem,  or
exchange shares,  wire funds and use Calvert Money Controller by telephone.  You
automatically  have telephone  privileges unless you elect otherwise.  The Fund,
the transfer agent and their  affiliates are not liable for acting in good faith
on  telephone  instructions  relating  to your  account,  so long as they follow
reasonable procedures to determine that the telephone  instructions are genuine.
Such  procedures  may include  recording the telephone  calls and requiring some
form of personal  identification.  You should  verify the  accuracy of telephone
transactions immediately upon receipt of your confirmation statement.

Optional Services 

Complete  the  "Option"  sections  of the  application  for the  easiest  way to
establish services.

The easiest way to establish  optional services on your Calvert Group account is
to select the options you desire when you complete your account application.  If
you wish to add other options later,  you may have to provide us with additional
information and a signature guarantee. Please call Calvert Investor Relations at
800-368-2745 for further assistance. For our mutual protection, we may require a
signature  guarantee  on  certain  written  transaction  requests.  A  signature
guarantee verifies the authenticity of your signature,  and may be obtained from
any  bank,   savings  and  loan  association,   credit  union,   trust  company,
broker-dealer firm or member of a domestic stock exchange. A signature guarantee
cannot be provided by a notary public.

Householding of General Mailings 

Householding   reduces  Fund   expenses  and  saves  paper  and  trees  for  the
environment.

If you have multiple accounts with Calvert, you may receive combined mailings of
some  shareholder  information,  such as semi-annual and annual reports.  Please
contact Calvert Investor  Relations at 800-368-2745 to receive additional copies
of information.

Special Services and Charges 

The Fund pays for  shareholder  services but not for special  services  that are
required by a few shareholders, such as a request for a historical transcript of
an  account.  You  may be  required  to pay a  research  fee for  these  special
services.

If you are purchasing  shares of the Fund through a program of services  offered
by a  broker-dealer  or  financial  institution,  you  should  read the  program
materials in conjunction with this Prospectus.  Certain features may be modified
in  these  programs,   and   administrative   charges  may  be  imposed  by  the
broker-dealer or financial institution for the services rendered.

Tax-Saving Retirement Plans 

Contact Calvert Group for complete  information  kits discussing the plans,  and
their benefits, provisions and fees.

Calvert  Group can set up your new  account  under one of  several  tax-deferred
plans.  These plans let you invest for  retirement  and shelter your  investment
income from current taxes. Minimums may differ from those listed in the chart on
page _____.  Also,  reduced  sales  charges may apply.  See "Exhibit A - Reduced
Sales Charges."

Individual  retirement  accounts  (IRAs):  available  to anyone  who has  earned
income.  You may also be able to make investments in the name of your spouse, if
your spouse has no earned income.

Qualified  Profit-Sharing  and  Money-Purchase  Plans (including  401(k) Plans):
available to  self-employed  people and their partners,  or to corporations  and
their employees.

Simplified  Employee Pension Plan (SEP-IRA):  available to self-employed  people

SELLING YOUR SHARES 

You may redeem all or a portion of your shares on any business  day. Your shares
will be redeemed at the next net asset value  calculated  after your  redemption
request is received and accepted.  See the chart below for specific requirements
necessary to make sure your redemption request is acceptable.  Remember that the
Fund may hold payment on the  redemption  of your shares until it is  reasonably
satisfied that  investments  made by check or by Calvert Money  Controller  have
been collected (normally up to 10 business days).

Redemption Requirements To Remember 

To ensure  acceptance of your redemption  request,  please follow the procedures
described here and below.

Once your shares are redeemed,  the proceeds will normally be sent to you on the
next business day, but if making  immediate  payment could adversely  affect the
Fund,  it may take up to seven (7) days.  Calvert Money  Controller  redemptions
generally will be credited to your bank account on the first or second  business
day after your phone call.  When the New York Stock  Exchange is closed (or when
trading is  restricted)  for any  reason  other  than its  customary  weekend or
holiday  closings,  or under any  emergency  circumstances  as determined by the
Securities  and  Exchange  Commission,  redemptions  may be suspended or payment
dates postponed.

Minimum account balance is $1,000. 

Please maintain a balance in your account of at least $1,000, per class. If, due
to redemptions,  the account falls below $1,000,  or you fail to invest at least
$1,000, your account may be closed and the proceeds mailed to you at the address
of record.  You will be given  notice that your  account will be closed after 30
days unless you make an additional  investment to increase your account  balance
to the $1,000 minimum.

Through your Broker 

If your  account  is held in your  broker's  name  ("street  name"),  you should
contact your broker directly to transfer, exchange or redeem shares.

DIVIDENDS, CAPITAL GAINS AND TAXES 

Each year, the Fund distributes  substantially  all of its net investment income
and capital gains to shareholders.

Dividends  from the Fund's net  investment  income  are  declared  and paid on a
monthly  basis.  Net  investment  income  consists of the interest  income,  net
short-term   capital  gains,  if  any,  and  dividends   declared  and  paid  on
investments,  less expenses.  Distributions of the Fund's net short-term capital
gains  (treated as dividends for tax  purposes)  and its net  long-term  capital
gains, if any, are normally declared and paid by the Fund once a year;  however,
the Fund does not  anticipate  making any such  distributions  unless  available
capital  loss  carryovers   have  been  used  or  have  expired.   Dividend  and
distribution payments will vary between classes; dividend payments are generally
anticipated to be higher for Class A shares.

Dividend and Distribution Payment Options. 

Dividends  and  any  distributions  are  automatically  reinvested  in the  same
Portfolio  at net asset  value (no sales  charge),  unless you elect to have the
dividends of $10 or more paid in cash (by check or by Calvert Money Controller).
Dividends and  distributions  may be  automatically  invested in an  identically
registered  account with the same account number in any other Calvert Group Fund
at net asset value.  If reinvested in the same Fund account,  new shares will be
purchased at net asset value on the reinvestment date, which is generally 1 to 3
days prior to the payment date. You must notify the Fund in writing prior to the
record  date to change  your  payment  options.  If you elect to have  dividends
and/or  distributions  paid in cash, and the U.S.  Postal Service cannot deliver
the  check,  or if it remains  uncashed  for six  months,  it, as well as future
dividends and distributions, will be reinvested in additional shares.

"Buying a Dividend" 

At the time of purchase,  the share price of the Fund may reflect  undistributed
income,  capital gains or unrealized  appreciation of securities.  Any income or
capital gains from these amounts  which are later  distributed  to you are fully
taxable.  On the  record  date for a  distribution,  the Fund's  share  value is
reduced by the amount of the  distribution.  If you buy shares  just  before the
record date ("buying a dividend") you will pay the full price for the shares and
then receive a portion of the price back as a taxable distribution.

Federal Taxes 

In  January,  the Fund will mail you Form  1099-DIV  indicating  the federal tax
status of  dividends  and  capital  gain  distributions  paid to you by the Fund
during the past year. Generally,  dividends and distributions are taxable in the
year they are paid. However, any dividends and distributions paid in January but
declared  during  the three  months  prior  are  taxable  in the year  declared.
Dividends and  distributions  are taxable to you  regardless of whether they are
taken in cash or reinvested.  Dividends, including short-term capital gains, are
taxable as ordinary  income.  Distributions  from  long-term  capital  gains are
taxable as long-term  capital gains,  regardless of how long you have owned Fund
shares.

You may realize a capital gain or loss when you sell or exchange shares. 

If you sell or  exchange  your Fund  shares  you will have a short or  long-term
capital  gain or loss,  depending  on how long you owned the  shares  which were
sold. In January,  the Fund will mail you Form 1099-B indicating the date of and
proceeds  from all  sales,  including  exchanges.  You should  keep your  annual
year-end  account  statements  to  determine  the cost  (basis) of the shares to
report on your tax returns.

Other Tax Information 

In addition to federal taxes, you may be subject to state or local taxes on your
investment,  depending  on the laws in your area.  You will be  notified  to the
extent, if any, that dividends  reflect interest  received from U.S.  government
securities.  Such  dividends  may be exempt from  certain  state  income  taxes.
Taxpayer Identification Number

If we do not have your correct Social Security or Taxpayer Identification Number
("TIN") and a signed certified application or Form W-9, Federal law requires the
Fund to withhold 31% of your dividends and certain redemptions. In addition, you
may be subject  to a fine.  You will also be  prohibited  from  opening  another
account by exchange.  If this TIN  information  is not  received  within 60 days
after your account is  established,  your account may be redeemed at the current
NAV on the date of  redemption.  The Fund  reserves  the right to reject any new
account or any purchase order for failure to supply a certified TIN.

EXHIBIT A 

REDUCED SALES CHARGES (CLASS A ONLY) 

You may  qualify for a reduced  sales  charge  through  several  purchase  plans
available. You must notify the Fund at the time of purchase to take advantage of
the reduced sales charge.

Right of Accumulation. The sales charge is calculated by taking into account not
only the dollar amount of a new purchase of shares,  but also the higher of cost
or current  value of shares  previously  purchased  in Calvert  Group Funds that
impose sales charges.  This  automatically  applies to your account for each new
purchase.

Letter of Intent.  If you plan to  purchase  $50,000 or more of Fund shares over
the next 13  months,  your  sales  charge  may be  reduced  through a "Letter of
Intent." You pay the lower sales charge  applicable to the total amount you plan
to invest over the 13-month  period,  excluding any money market fund purchases.
Part of your  shares  will be held in  escrow,  so that if you do not invest the
amount  indicated,  you will  have to pay the  sales  charge  applicable  to the
smaller  investment  actually made. For more  information,  see the Statement of
Additional Information.

Group  Purchases.  If you are a member of a qualified  group,  you may  purchase
shares of the Fund at the reduced sales charge  applicable to the group taken as
a whole.  The sales  charge is  calculated  by taking into  account not only the
dollar amount of the shares you purchase, but also the higher of cost or current
value of shares previously purchased and currently held by other members of your
group.

A  "qualified  group" is one which (i) has been in  existence  for more than six
months,  (ii) has a purpose other than acquiring Fund shares at a discount,  and
(iii)  satisfies  uniform  criteria  which enable CDI and dealers  offering Fund
shares to realize  economies of scale in distributing  such shares.  A qualified
group must have more than 10  members,  must be  available  to arrange for group
meetings  between  representatives  of CDI or  dealers  distributing  the Fund's
shares,  must agree to include sales and other materials  related to the Fund in
its  publications  and  mailings  to  members  at  reduced  or no cost to CDI or
dealers,  and  must  seek  to  arrange  for  payroll  deduction  or  other  bulk
transmission of investments to the Fund.

Pension plans may not qualify  participants for group purchases;  however,  such
plans may qualify for reduced  sales  charges  under a separate  provision  (see
below). Members of a group are not eligible for a Letter of Intent.

Retirement Plans Under Section 457, Section 403(b)(7),  or Section 401(k). There
is no sales  charge on shares  purchased  for the benefit of a  retirement  plan
under Section 457 of the Internal Revenue Code of 1986, as amended ("Code"),  or
for a plan  qualifying  under  Section  403(b)(7) of the Code if, at the time of
purchase, Calvert Group has been notified in writing that the 403(b)(7) plan has
at least 200 eligible employees. Furthermore, there is no sales charge on shares
purchased for the benefit of a retirement plan  qualifying  under Section 401(k)
of the Code if, at the time of such purchase,  the 401(k) plan administrator has
notified  Calvert  Group in  writing  that a) its  401(k)  plan has at least 200
eligible  employees;  or b) the cost or current  value of shares the plan has in
Calvert Group of Funds (except money market funds) is at least $1 million.

Neither the Fund,  nor CDI, nor any affiliate  thereof will  reimburse a plan or
participant  for any  sales  charges  paid  prior  to  receipt  of such  written
communication and confirmation by Calvert Group. Plan administrators should send
requests  for the  waiver of sales  charges  based on the above  conditions  to:
Calvert Group Retirement Plans, 4550 Montgomery Avenue,  Suite 1000N,  Bethesda,
Maryland 20814.

Other  Circumstances.  There is no sales charge on shares of any fund (portfolio
or series) of the Calvert Group of Funds sold to (i) current and retired members
of the Board of  Trustees/Directors  of the  Calvert  Group of  Funds,  (and the
Advisory  Council  of the  Calvert  Social  Investment  Fund);  (ii)  directors,
officers  and  employees  of the  Advisor,  Distributor,  and  their  affiliated
companies;  (iii) directors,  officers and registered representatives of brokers
distributing  the Fund's shares;  and immediate family members of persons listed
in (i), (ii), and (iii), above; (iv) dealers,  brokers, or registered investment
advisors that have entered into an agreement with CDI providing specifically for
the use of shares of the Fund  (Portfolio  or Series) in  particular  investment
programs or products  (where such  program or product  already has a fee charged
therein)  made  available to the clients of such dealer,  broker,  or registered
investment advisor;  (v) trust departments of banks or savings  institutions for
trust clients of such bank or savings  institution;  and (vi)  purchases  placed

                       INVESTMENT OBJECTIVES AND POLICIES 

Calvert U.S.  Government  Fund pursues its  objective of providing  high current
income  consistent  with safety of principal  by  investing in a  professionally
managed portfolio  consisting primarily of U.S.  Government-backed  obligations.
There is no  limitation  on the maturity of  obligations  in which  Calvert U.S.
Government Fund may invest.

Calvert Income Fund seeks to maximize  long-term income to the extent consistent
with  prudent  investment  management  and  preservation  of  capital,   through
investment in bonds and other income  producing  securities of investment  grade
quality.  The Fund may  invest in debt  securities  backed by the full faith and
credit of the U.S. Government,  such as Government National Mortgage Association
("GNMA")  certificates,  and may also  invest in other debt  securities  such as
collateralized mortgage obligations.

Each Fund offers investors the opportunity to invest in a professionally managed
securities portfolio which may be more diversified, stable and liquid than might
be obtainable by an investor on an individual basis. There can be, of course, no
assurance that any Fund will be successful in meeting its investment objective.

Collateralized Mortgage Obligations
 
Calvert U.S.  Government  Fund and Calvert  Income Fund may, in pursuit of their
investment   objectives,   invest  in   collateralized   mortgage   obligations.
Collateralized  mortgage  obligations  ("CMOs") are  fully-collateralized  bonds
which are general  obligations  of the issuer of the bonds.  CMOs  generally are
secured by  collateral  consisting  of  mortgages  or a pool of  mortgages.  The
collateral is assigned to the trustee  named in the indenture  pursuant to which
the bonds are  issued.  Payments of  principal  and  interest on the  underlying
mortgages  are not passed  through  directly  to the holder of the CMO;  rather,
payments to the trustee are dedicated to payment of interest on and repayment of
principal  of the CMOs.  This means that the  character of payments of principal
and  interest  is not  passed  through,  so that  payments  to  holders  of CMOs
attributable to interest paid and principal  repaid on the underlying  mortgages
or pool of mortgages do not necessarily constitute income and return of capital,
respectively,  to the CMO  holders.  Also,  because  payments of  principal  and
interest are not passed through,  CMOs secured by the same pool or mortgages may
be, and frequently are,  issued with a variety of classes or series,  which have
different  maturities  and are  retired  sequentially.  CMOs are  designed to be
retired as the  underlying  mortgages are repaid.  In the event of prepayment on
such  mortgages,  the class of CMO first to mature  generally will be paid down.
Thus  there  should be  sufficient  collateral  to secure  the CMOs that  remain
outstanding even if the issuer does not supply additional collateral.  FHLMC has
introduced a CMO which is a general obligation of FHLMC.
This requires FHLMC to use its general funds to make payments on the CMO if
payments from the underlying mortgages are insufficient.

CMOs are not direct obligations of the U.S. Government. However, Calvert U.S.
Government  Fund will purchase only those CMOs which are U.S.  Government-backed
obligations,  in that they are fully  collateralized by mortgages (such as those
insured by the Federal  Housing  Administration  or  guaranteed  by the Veterans
Administration)  or  mortgage-related  obligations  (such as GNMA, FNMA or FHLMC
Certificates)  which are issued or guaranteed  by the United States  Government,
its agencies, or its instrumentalities.

U.S. Government-Backed Obligations
 
Calvert U.S. Government Fund and Calvert Income Fund may, in pursuit of
their investment objectives, invest in Ginnie Maes, Fannie Maes, Freddie
Macs, U.S. Treasury obligations, and other U.S. Government-backed
obligations.

Ginnie Maes. Calvert U.S. Government Fund and Calvert Income Fund may
invest in Ginnie Maes. Ginnie Maes, issued by the Government National
Mortgage Association, are typically interests in pools of mortgage loans
insured by the Federal Housing Administration or guaranteed by the Veterans
Administration. A "pool" or group of such mortgages is assembled and, after
approval from GNMA, is offered to investors through various securities
dealers. GNMA is a U.S. Government corporation within the Department of
Housing and Urban Development. Ginnie Maes are backed by the full faith and
credit of the United States, which means that the U.S. Government
guarantees that interest and principal will be paid when due. Fannie Maes
and Freddie Macs. 

Fannie Maes and Freddie Macs are issued by the Federal National Mortgage
Association ("FNMA") and Federal Home Loan Mortgage Corporation ("FHLMC"),
respectively. Unlike GNMA certificates, which are typically interests in
pools of mortgages insured or guaranteed by government agencies, FNMA and
FHLMC certificates represent undivided interests in pools of conventional
mortgage loans. Both FNMA and FHLMC guarantee timely payment of principal
and interest on their obligations, but this guarantee is not backed by the
full faith and credit of the U.S. Government. FNMA's guarantee is supported
by its ability to borrow from the U.S. Treasury, while FHLMC's guarantee is
backed by reserves set aside to protect holders against losses due to
default.
         
U.S. Treasury Obligations. Direct obligations of the United States Treasury
are backed by the full faith and credit of the United States. They differ
only with respect to their rates of interest, maturities, and times of
issuance. U.S. Treasury obligations consist of: U.S. Treasury bills (having
maturities of one year or less), U.S. Treasury notes (having maturities of
one to ten years ) and U.S. Treasury bonds (generally having maturities
greater than ten years).
         
Other U.S. Government Obligations. Each Fund may invest in other
obligations issued or guaranteed by the U.S. Government, its agencies, or
its instrumentalities. (Certain obligations issued or guaranteed by a U.S.
Government agency or instrumentality may not be backed by the full faith
and credit of the United States.)

Repurchase Agreements
 
         
Each Fund may, in pursuit of its investment objectives, purchase securities
subject to repurchase agreements. Repurchase agreements are transactions in
which a person purchases a security and simultaneously commits to resell
that security to the seller at a mutually agreed upon time and price. The
seller's obligation is secured by the underlying security. The repurchase
price reflects the initial purchase price plus an agreed upon market rate
of interest. While an underlying security may bear a maturity in excess of
one year, the term of the repurchase agreement is always less than one
year. Repurchase agreements not terminable within seven days will be
limited to no more than 10% of each Fund's assets. Repurchase agreements
are short-term money market investments, designed to generate current
income.

Each Fund will only engage in repurchase agreements with recognized
securities dealers and banks determined to present minimal credit risk by
the Advisor.
         
Each Fund will only engage in repurchase agreements reasonably designed to
secure fully during the term of the agreement the seller's obligation to
repurchase the underlying security and will monitor the market value of the
underlying security during the term of the agreement. If the value of the
underlying security declines and is not at least equal to the repurchase
price due to the Fund pursuant to the agreement, the Fund will require the
seller to pledge additional securities or cash to secure the seller's
obligations pursuant to the agreement. If the seller defaults on its
obligation to repurchase and the value of the underlying security declines,
the Fund may incur a loss and may incur expenses in selling the underlying
security.

Non-Investment Grade Debt Securities
 
         
Calvert Income Fund may invest in lower quality debt securities (generally
those rated BB or lower by S&P or Ba or lower by Moody's), subject to the
Fund's investment policy which provides that the Fund may not invest more
than 20% of its assets in securities rated below BBB by either rating
service, or in unrated securities determined by the Advisors to be
comparable to securities rated below BBB by either rating service. These
securities have moderate to poor protection of principal and interest
payments and have speculative characteristics. These securities involve
greater risk of default or price declines due to changes in the issuer's
creditworthiness than investment-grade debt securities. Because the market
for lower-rated securities may be thinner and less active than for
higher-rated securities, there may be market price volatility for these
securities and limited liquidity in the resale market. Market prices for
these securities may decline significantly in periods of general economic
difficulty or rising interest rates. Unrated debt securities may fall into
the lower quality category. Unrated securities usually are not attractive
to as many buyers as rated securities are, which may make them less
marketable.
          
The quality limitation set forth in the Fund's investment policy is
determined immediately after the Fund's acquisition of a given security.
Accordingly, any later change in ratings will not be considered when
determining whether an investment complies with the Fund's investment
policy. When purchasing high-yielding securities, rated or unrated, the
Advisors

prepare their own careful credit analysis to attempt to identify those
issuers whose financial condition is adequate to meet future obligations or
is expected to be adequate in the future. Through portfolio diversification
and credit analysis, investment risk can be reduced, although there can be
no assurance that losses will not occur.

Options and Futures Contracts
          
Covered Options. Calvert U.S. Government Fund may, in pursuit of its
investment objectives, engage in the writing of covered call options and
secured put options against U.S. Government-backed obligations and in a
variety of other investment techniques seeking to hedge against changes in
the general level of interest rates, including the purchase of put and call
options on debt securities and the purchase and sale of interest rate
futures contracts and options on such futures. The Fund will not engage in
such transactions for the purpose of speculation or leverage. Such
investment policies and techniques may involve a greater degree of risk
than those inherent in more conservative investment approaches.

Covered Options on Debt Securities. Calvert U.S. Government Fund may write
"covered options" on debt securities in standard contracts traded on
national securities exchanges and in the over-the-counter market. At
present, exchange-traded options are available only on U.S. Treasury bills,
notes and bonds. The Fund will write such options in order to receive the
premiums from options that expire and to seek net gains from closing
purchase transactions with respect to such options.

The Fund may write only "covered options." This means that, in the case of
call options, so long as each Fund is obligated as the writer of a call
option, it will own the underlying security subject to the option and, in
the case of put options, the Fund will, through its custodian, deposit and
maintain with a securities depository U.S. Treasury obligations with a
market value equal to or greater than the exercise price of the option.

The Fund will not engage in options or futures transactions unless it
receives appropriate regulatory approvals permitting the Fund to engage in
such transactions. The Fund observes the following operating policy, which
may be changed without the approval of a majority of the outstanding
shares: The Fund will not invest in options and futures contracts if as a
result more than 5% of its assets would be so invested or if the aggregate
market value of the futures contracts it holds would exceed 30% of the
market value of its total assets.
        
Calvert Income Fund may, in pursuit of its investment objectives, write
"covered call options" in standard contracts traded on national securities
exchanges or quoted on NASDAQ, provided that: (1) the Fund continues to own
the securities covering each call option until the call option has been
exercised or until the Fund has purchased a closing call to offset its
obligation to deliver securities pursuant to the call option it had
written; and (2) the market value of all securities covering call options
in the Fund does not exceed 20% of the market value of the Fund's total
assets. Calvert Income Fund anticipates that the market value of securities
covering call options will not exceed 5% of assets during the coming year.

Characteristics of Covered Options. When a Fund writes a covered call
option, the Fund gives the purchaser the right to purchase the security at
the call option price at any time during the life of the option. As the
writer of the option, the Fund receives a premium, less a commission, and
in exchange foregoes the opportunity to profit from any increase in the
market value of the security exceeding the call option price. The premium
serves to mitigate the effect of any depreciation in the market value of
the security. Writing covered call options can increase the income of each
Fund and thus reduce declines in the net asset value per share of the Fund
if securities covered by such options decline in value. Exercise of a call
option by the purchaser however will cause the Fund to forego future
appreciation of the securities covered by the option.

When Calvert U.S. Government Fund writes a secured put option, it will gain
a profit in the amount of the premium, less a commission, so long as the
price of the underlying security remains above the exercise price. However,
the Fund remains obligated to purchase the underlying security from the
buyer of the put option (usually in the event the price of the security
falls below the exercise price) at any time during the option period. If
the price of the underlying security falls below the exercise price, the
Fund may realize a loss in the amount of the difference between the
exercise price and the sale price of the security, less the premium
received.

Each Fund purchases securities which may be covered with call options
solely on the basis of considerations consistent with the investment
objectives and policies of the Fund.

Each Fund will  purchase a put or call option  only when  engaging in a "closing
purchase  transaction" that is, the purchase of a put or call option on the same
security with the same exercise  price and  expiration  date as a covered put or
call option the Fund has previously  written.  Of course,  there is no assurance
that the Fund  will be able to  secure a  favorable  price in  effecting  such a
transaction,  and  circumstances  might  require  that  it  hold a  security  it
otherwise might have sold.

Each Fund's  turnover may increase  through the exercise of a call option;  this
will generally occur if the market value of a "covered"  security  increases and
the Fund has not entered into a closing purchase transaction.

Expiration of a put or call option or entry into a closing purchase  transaction
will result in a short-term  capital gain, unless the cost of a closing purchase
transaction  exceeds the premium the Fund received  when it initially  wrote the
option,  in which case a short-term  capital loss will result.  If the purchaser
exercises a put or call  option,  the Fund will  realize a gain or loss from the
sale of the security acquired or sold pursuant to the option, and in determining
the gain or loss the  premium  will be  included  in the  proceeds  of sale.  To
preserve each Fund's status as a regulated investment company under Subchapter M
of the Internal Revenue Code, it is each Fund's policy to limit any gains on put
or call  options and other  securities  held less than three months to less than
30% of each Fund's annual gross income.

Risks  Related to Options  Transactions.  A Fund can close out its  positions in
exchange traded options only on an exchange which provides a secondary market in
such  options.  Although  each Fund  intends  to  acquire  and  write  only such
exchange-traded  options for which an active  secondary market appears to exist,
there can be no  assurance  that  such a market  will  exist for any  particular
option  contract at any  particular  time.  Exchange  markets in options on U.S.
Government  securities  are  relatively  new and it is difficult  to  accurately
predict the extent of trading  interest  that may develop  with  respect to such
options. This might prevent a Fund from closing an options position, which could
impair the Fund's  ability to hedge its  portfolio  effectively.  Also, a Fund's
inability  to close  out a call  position  may  have an  adverse  effect  on its
liquidity because the Fund may be required to hold the securities underlying the
option until the option expires or is exercised.

The  hours  of  trading  for  options  on  U.S.  Government  securities  may not
correspond exactly to the hours of trading for the underlying securities. To the
extent that the options  markets  close  before the U.S.  Government  securities
markets,  significant  movements in rates and prices may occur in the Government
securities markets that cannot be reflected in the options markets.

Interest  Rate Futures  Transactions.  A change in the general level of interest
rates will affect the market  value of debt  securities  in a Fund's  portfolio.
Calvert  U.S.  Government  Fund may  purchase  and sell  interest  rate  futures
contracts ("futures  contracts") as a hedge against changes in interest rates in
accordance  with the  strategies  described  below.  A  futures  contract  is an
agreement  between two parties to buy and sell a security on a future date which
has the effect of  establishing  the current  price for the  security.  Although
futures  contracts by their terms  require  actual  delivery and  acceptance  of
securities,  in most cases the  contracts  are closed out before the  settlement
date without the making or taking of delivery of securities.  Upon purchasing or
selling a futures contract, the Fund deposits initial margin with its custodian,
and thereafter  daily  payments of  maintenance  margin are made to and from the
executing broker. Payments of maintenance margin reflect changes in the value of
the futures  contract,  with each Fund being  obligated to make such payments if
its futures position becomes less valuable and entitled to receive such payments
if its position becomes more valuable.

Futures  contracts  have  been  designed  by  boards  of trade  which  have been
designated  "contract  markets"  by the  Commodity  Futures  Trading  Commission
("CFTC").  As a series of a registered investment company, each Fund is eligible
for exclusion from the CFTC's  definition of "commodity pool operator,"  meaning
that the Fund may invest in futures contracts under specified conditions without
registering with the CFTC. Among these conditions are requirements that the Fund
invest in futures  only for  hedging  purposes  and that the Fund commit no more
than 5% of the fair market  value of its assets to commodity  interest  trading.
Futures  contracts trade on contract  markets in a manner that is similar to the
way a stock trades on a stock exchange,  and the boards of trade,  through their
clearing corporations,  guarantee performance of the contracts. Currently, there
are futures  contracts  based on long-term U.S.  Treasury bonds,  U.S.  Treasury
notes,   three-month  U.S.   Treasury  bills,  and  three-month   domestic  bank
certificates of deposit.

The  purchase  and sale of futures  contracts is for the purpose of hedging each
Fund's holdings of long-term debt  securities.  Futures  contracts based on U.S.
Government  securities  and GNMA  Certificates  historically  have reacted to an
increase  or decrease  in  interest  rates in a manner  similar to the manner in
which  mortgage-related  securities  reacted to the change.  If  interest  rates
increase,  the value of such  securities in the Fund's  portfolio would decline,
but the  value of a short  position  in  futures  contracts  would  increase  at
approximately  the same rate,  thereby  keeping  the net asset value of the Fund
from  declining  as  much as it  otherwise  would  have.  Thus,  if a Fund  owns
long-term securities and interest rates were expected to increase, it might sell
futures contracts rather than sell its holdings of long-term securities.  If, on
the other hand,  the Fund held cash reserves and interest rates were expected to
decline,  the Fund might enter into futures  contracts  for the purchase of U.S.
Government  securities  or GNMA  certificates  and thus  take  advantage  of the
anticipated  risk in the value of long-term  securities  without actually buying
them until the market had stabilized.  At that time, the futures contracts could
be liquidated  and the Fund's cash reserves  could then be used to buy long-term
securities  in the cash market.  The Fund could  accomplish  similar  results by
selling  securities  with long maturities and investing in securities with short
maturities when interest rates are expected to increase or by buying  securities
with long maturities and selling  securities with short maturities when interest
rates are expected to decline.  But by using futures  contracts as an investment
tool to manage risk it might be possible to  accomplish  the same result  easily
and quickly.

Options on Futures  Contracts.  Calvert  U.S.  Government  Fund may purchase and
write  call and put  options  on  futures  contracts  which are traded on a U.S.
exchange or board of trade and enter into closing  transactions  with respect to
such options to terminate an existing position.  An option on a futures contract
gives the  purchaser  the right,  in return for the  premium  paid,  to assume a
position  in a futures  contract a long  position  if the option is a call and a
short position if the option is a put at a specified  exercise price at any time
during the period of the option.  The Fund will pay a premium  for such  options
which it purchases.  In connection  with such options which it writes,  the Fund
will  make  initial  margin  deposits  and make or  receive  maintenance  margin
payments  which  reflect  changes  in the  market  value of such  options.  This
arrangement  is  similar  to  the  margin  arrangements  applicable  to  futures
contracts described above.

Purchase of Put  Options on Futures  Contracts.  The  purchase of put options on
futures  contracts is analogous to the sale of futures  contracts and is used to
protect the Fund's  portfolio of debt  securities  against the risk of declining
prices.

Purchase of Call Options on Futures  Contracts.  The purchase of call options on
futures contracts  represents a means of obtaining  temporary exposure to market
appreciation  at limited  risk.  It is  analogous  to the  purchase of a futures
contract  and is used to protect  against a market  advance when the Fund is not
fully invested.

Writing  Call  Options  on Futures  Contracts.  The  writing of call  options on
futures  contracts  constitutes a partial hedge against  declining prices of the
debt securities which are deliverable upon exercise of the futures contracts. If
the futures  contract price at expiration is below the exercise price,  the Fund
will retain the full amount of the option premium which provides a partial hedge
against  any  decline  that may have  occurred  in the Fund's  holdings  of debt
securities.

Writing Put Options on Futures Contracts.  The writing of put options on futures
contracts is analogous  to the  purchase of futures  contracts.  If an option is
exercised,  the net cost to the Fund of the debt securities  acquired by it will
be reduced by the amount of the option premium  received.  Of course,  if market
prices have  declined,  the Fund's  purchase  price upon exercise may be greater
than the  price at which  the debt  securities  might be  purchased  in the cash
market.

Risks of Options and Futures  Contracts.  If the Fund has sold  futures or takes
options  positions to hedge its portfolio  against decline in the market and the
market later  advances,  the Fund may suffer a loss on the futures  contracts or
options which it would not have experienced if it had not hedged. The success of
a hedging strategy depends on the Advisor's  ability to predict the direction of
interest rates and other  economic  factors.  Correlation  is imperfect  between
movements in the prices of futures or options  contracts and movements in prices
of the  securities  which are the subject of the hedge.  Thus,  the price of the
futures  contract  or  option  may move  more than or less than the price of the
securities  being hedged.  If a Fund used a futures or options contract to hedge
against a decline in the market,  and the market later advances (or vice versa),
the Fund may suffer a greater loss than if it had not hedged. However, the value
of a diversified  portfolio  such as a Fund's will tend to move in the direction
of the market generally.

A Fund can close out its futures positions only on an exchange or board of trade
which provides a secondary market in such futures. Although each Fund intends to
purchase or sell only such futures for which an active  secondary market appears
to  exist,  there can be no  assurance  that  such a market  will  exist for any
particular  futures contract at any particular time. This might prevent the Fund
from closing a futures position, which could require the Fund to make daily cash
payments with respect to its position in the event of adverse  price  movements.
In such  situations,  if the Fund  has  insufficient  cash,  it may have to sell
portfolio  securities to meet daily margin  requirements at a time when it would
be disadvantageous to do so. The inability to close futures or options positions
could have an adverse effect on the Fund's ability to hedge  effectively.  There
is also risk of loss by the Fund of margin  deposits in the event of  bankruptcy
of a broker with whom the Fund has an open  position in a futures  contract.  To
partially  or  completely  offset  losses on  futures  contracts,  the Fund will
normally  hold the  securities  against which the futures  positions  were taken
until the futures  positions  can be closed out, so that the Fund  receives  the
gain (if any) from the portfolio  securities.  This might have an adverse effect
on the Fund's overall liquidity.

Options on futures  transactions bear several risks apart from those inherent in
options  transactions  generally.  A Funds  ability  to  close  out its  options
positions  in futures  contracts  will depend upon  whether an active  secondary
market for such options  develops and is in existence at the time the Fund seeks
to close its position. There can be no assurance that such a market will develop
or exist.  Therefore,  the Fund might be  required  to  exercise  the options to
realize any profit.

Restricted Securities
         
Calvert Income Fund may invest in restricted  (privately  placed) securities and
other  securities  which are not readily  marketable.  Such securities may offer
greater  potential  for  capital  appreciation  or  income  than  non-restricted
securities.  The Fund  may not  invest  in such  securities  if,  at the time of
acquisition,  such investment  would cause the total percentage of restricted or
non-readily marketable securities in the Fund to exceed 10% of its total assets.

Restricted securities may be sold only in privately negotiated transactions,  in
a public  offering  for which a  registration  statement  is in effect under the
Securities Act of 1933 (the "Act") or, where  applicable,  pursuant to Rule 144A
of the Act. If registration is required to effect sales of the security the Fund
may be obligated to bear all or part of the registration expenses and wait until
the appropriate  registration  statement  becomes  effective before it makes the
sale. If adverse market  conditions  develop during such a period,  the Fund may
not be able to obtain as favorable a price as that prevailing when it decided to
sell. The Fund's  investments in restricted  securities are valued at fair value
as determined by the Advisor under the supervision of the Board of Trustees.  In
determining fair value, the market price of comparable  securities,  if any, the
book value per share, and other intrinsic  financial  information  regarding the
issuer and the securities will be taken into  consideration.  If, as a result of
the appreciation in value of restricted  securities or the depreciation in value
of  unrestricted  securities,  either  Fund's  proportion  of such assets should
exceed 10% of the value of its assets,  the Board will take appropriate steps to
protect liquidity.

Loans of Portfolio Securities
 
         
Each Fund may lend the securities  from its portfolio to member firms of the New
York Stock Exchange and commercial  banks with assets of one billion  dollars or
more.  Any such loans must be secured  continuously  in the form of cash or cash
equivalents  such as U.S.  Treasury  bills,  the amount of collateral  must on a
current basis equal or exceed the market value of the loaned securities, and the
Fund must be able to terminate  such loans upon notice,  at any time.  Each Fund
will exercise its right to terminate a securities  loan in order to preserve its
right to vote upon matters of importance  affecting  holders of the  securities.
Each Fund may make loans of its  securities  only if the value of the securities
loaned from the Fund will not exceed one-third of the Fund's assets.

The advantage of such loans is that the Fund continues to receive the equivalent
of the interest earned or dividends paid by the issuer on the loaned  securities
while at the same time  earning  interest on the cash or  equivalent  collateral
which may be  invested  in  accordance  with the  Fund's  investment  objective,
policies and restrictions.

Securities  loans  are  usually  made  to  broker-dealers  and  other  financial
institutions  to facilitate  their  deliveries of such  securities.  As with any
extension of credit there may be risks of delay in recovery and possibly loss of
rights in the loaned  securities  should the  borrower of the loaned  securities
fail financially. However, each Fund will make loans of its portfolio securities
only to those firms the Advisor deems creditworthy and only on such terms as the
Advisor believes should compensate for such risk. On termination of the loan the
borrower is obligated to return the  securities to the Fund; any gain or loss in
the market value of the security  during the loan period will inure to the Fund.
The Fund may pay reasonable custodial fees in connection with the loan.

International Money Market Instruments 
         
Calvert Income Fund may, in pursuit of its investment objective,  invest in U.S.
dollar-denominated  obligations  of  foreign  branches  of U.S.  banks  and U.S.
branches  of foreign  banks.  Such  obligations  are not  insured by the Federal
Deposit Insurance  Corporation.  Foreign and domestic bank reserve  requirements
may differ.  Payment of interest and principal  upon these  obligations  and the
marketability and liquidity of such obligations in the secondary market may also
be  affected  by  governmental  action in the  country of domicile of the branch
(generally  referred to as "sovereign risk").  Examples of governmental  actions
would be the imposition of exchange or currency controls,  interest  limitations
or withholding  taxes on interest income,  seizure of assets, or the declaration
of a moratorium on the payment of principal or interest. In addition,  evidences
of ownership of portfolio  securities  may be held outside of the U.S., and each
Fund may be subject to the risks  associated  with the holding of such  property
overseas.

The  obligations  of foreign  branches  of U.S.  banks and of U.S.  branches  of
foreign banks may be general obligations of the parent bank in addition to being
obligations of the issuing  branch,  or may be limited to being an obligation of
the issuing  branch by the terms of the  specific  obligation  or by  government
action or regulation.  Obligations which are limited to being obligations of the
issuing branch may involve  greater risks than  obligations  which are generally
obligations  of the parent bank in addition to being  obligations of the issuing
branch.

The Fund will carefully  consider these factors in making such  investments  and
will   invest  no  more   than  25%  of  the   value  of  its   assets  in  U.S.
dollar-denominated  obligations  of  foreign  branches  of U.S.  banks  and U.S.
branches of foreign banks.

Bond Ratings
 
Description of Moody's Investors Service Inc.'s/Standard & Poor's bond ratings: 
         
Aaa/AAA: Best quality.  These bonds carry the smallest degree of investment risk
and are generally referred to as "gilt edge." Interest payments are protected by
a large or by an  exceptionally  stable  margin and  principal  is secure.  This
rating indicates an extremely strong capacity to pay principal and interest.

Aa/AA: Bonds rated AA also qualify as high-quality debt obligations. Capacity to
pay principal and interest is very strong, and in the majority of instances they
differ from AAA issues only in small degree.  They are rated lower than the best
bonds because  margins of protection  may not be as large as in Aaa  securities,
fluctuation of protective elements may be of greater amplitude,  or there may be
other elements present which make long-term risks appear somewhat larger than in
Aaa securities.

A/A:  Upper-medium grade  obligations.  Factors giving security to principal and
interest are  considered  adequate,  but elements may be present  which make the
bond somewhat  more  susceptible  to the adverse  effects of  circumstances  and
economic conditions.

Baa/BBB:  Medium  grade  obligations;  adequate  capacity to pay  principal  and
interest. Whereas they normally exhibit adequate protection parameters,  adverse
economic  conditions  or  changing  circumstances  are more  likely to lead to a
weakened  capacity to pay principal and interest for bonds in this category than
for bonds in the A category.

Ba/BB,  B/B,  Caa/CCC,  Ca/CC:  Debt rated in these  categories  is  regarded as
predominantly  speculative  with  respect to capacity to pay  interest and repay
principal.  There may be some large  uncertainties  and major risk  exposure  to
adverse conditions. The higher the degree of speculation, the lower the rating.

C/C: This rating is only for no-interest income bonds. 
         
D:  Debt  in  default;  payment  of  interest  and/or  principal  is in 
arrears. 

Commercial Paper Ratings 
         
Commercial  paper rated A by  Standard & Poor's  Corporation  has the  following
characteristics:  liquidity  ratios  are  adequate  to meet  cash  requirements;
long-term senior debt is rated "A" or better;  the issuer has access to at least
two  additional  channels of  borrowing;  basic  earnings  and cash flow have an
upward  trend with  allowance  made for unusual  circumstances;  typically,  the
issuer's  industry  is well  established  and the issuer  has a strong  position
within  the  industry;  and  the  reliability  and  quality  of  management  are
unquestioned.  The relative strength or weakness of the above factors determines
whether an issuer's commercial paper is rated A-1, A-2, or A-3.

Issuers rated Prime-1 by Moody's Investors Service, Inc., are considered to have
superior  capacity for  repayment of  short-term  promissory  obligations.  Such
repayment capacity will normally be evidenced by the following  characteristics:
leading market positions in well-established industries; high rates of return on
funds employed;  conservative capitalization structure with moderate reliance on
debt and ample asset  protection;  broad  margins in earnings  coverage of fixed
financial charges and high internal cash generation; and well established access
to a range of  financial  markets and assured  sources of  alternate  liquidity.
Issuers  rated  Prime-2  have a strong  capacity  for  repayment  of  short-term
promissory  obligations.  This  will  normally  be  evidenced  by  many  of  the
characteristics cited above but to a lesser degree. Earnings trends and coverage
ratios,  while  sound,  will  be  more  subject  to  variation.   Capitalization
characteristics,  while  still  appropriate,  may be more  affected  by external
conditions. Ample alternate liquidity is maintained.


                            INVESTMENT RESTRICTIONS 

        
The  Calvert  Fund  has  adopted  the  following  investment   restrictions  and
fundamental policies.  These restrictions cannot be changed without the approval
of the holders of a majority of the  outstanding  shares of the Fund. As defined
in the Investment  Company Act of 1940, this means the lesser of the vote of (a)
67% of  the  shares  of  the  Fund  at a  meeting  where  more  than  50% of the
outstanding shares are present in person or by proxy or (b) more than 50% of the
outstanding  shares of the Fund.  Shares have equal rights as to voting,  except
that only shares of a series are entitled to vote on matters, such as changes in
investment objective, policies or restrictions, affecting only that series. 

None of the Funds may:

         1.       Purchase   securities   of  any  issuer  (other  than 
         obligations   of,  or   guaranteed   by,  the  United   States 
         Government,  its  agencies  or  instrumentalities)  if,  as  a 
         result,  more than 5% of the value of the Fund's  total assets 
         would be invested in securities of such issuer. 
         2.       Concentrate  more  than  25%  of  the  value  of  its 
         assets in any one industry;  provided,  however, that there is 
         no  limitation  with  respect to  investments  in  obligations 
         issued or guaranteed  by the United  States  Government or its 
         agencies and instrumentalities. 
         3.       Purchase  more  than  10% of the  outstanding  voting 
         securities  of any  issuer.  In  addition,  all  series of The 
         Calvert  Fund may not together  purchase  more than 10% of the 
         outstanding voting securities of any issuer. 
         4.       Make  loans  (other  than  loans  of  its   portfolio 
         securities,   loans  through  the  purchase  of  money  market 
         instruments  and repurchase  agreements,  or loans through the 
         purchase  of bonds,  debentures  or other debt  securities  of 
         the  types  commonly   offered   privately  and  purchased  by 
         financial  institutions).  The  purchase  of a  portion  of an 
         issue of  publicly  distributed  debt  obligations  shall  not 
         constitute the making of loans. 
         5.       Underwrite the securities of other issuers. 
         6.       Purchase  securities  which are  subject  to legal or 
         contractual  restrictions  on resale or for which  there is no 
         readily  available  market or which are repurchase  agreements 
         not  terminable  within  seven  days if more  than  10% of the 
         value of any  Fund's  net  assets  would be  invested  in such 
         securities. 
         7.       Purchase  from or sell to any of the Fund's  officers 
         or Trustees,  or firms of which any of them are  members,  any 
         securities  (other than capital  stock of the Fund),  but such 
         persons  or  firms  may  act  as  brokers  for  the  Fund  for 
         customary commissions. 
         8.       Issue  senior  securities  or  borrow  money,  except 
         from  banks  as  a  temporary  measure  for  extraordinary  or 
         emergency  purposes  and then  only in an  amount up to 10% of 
         the  value of its  total  assets  in order to meet  redemption 
         requests without  immediately  selling  portfolio  securities. 
         The  writing  of  covered  call  options  is  not   considered 
         issuing a senior  security.  In order to secure  any such bank 
         borrowings under this section,  the Fund may pledge,  mortgage 
         or  hypothecate  its assets and then in an amount not  greater 
         than 15% of the value of its total  assets.  The Fund will not 
         borrow for leverage  purposes and investment  securities  will 
         not be purchased while any borrowings are outstanding. 
         9.       Make  short  sales  of   securities,   purchase   any 
         securities on margin, or invest in warrants. 
         10.      Write,  purchase or sell puts,  straddles or spreads, 
         or  combinations  thereof;  provided,  however,  that  Calvert 
         U.S.  Government  Fund may write cash  secured put options and 
         engage  in  closing   purchase   transactions  to  the  extent 
         permitted by their investment objectives and policies. 
         11.      Purchase  or retain the  securities  of any issuer if 
         any officer or Trustee of the Fund or its  Investment  Advisor 
         owns  beneficially  more than 1/2 of 1% of the  securities  of 
         such issuer or if together such  individuals  own more than 5% 
         of the securities of such issuer. 
         12.      Invest  for the  purpose  of  exercising  control  or 
         management of another issuer. 
         13.      Invest   in    commodities,    commodities    futures 
         contracts,   or  real  estate,   although  it  may  invest  in 
         securities  which are  secured by real  estate or real  estate 
         mortgages  and may invest in the  securities  of issuers which 
         invest  or  deal  in  commodities,   commodity  futures,  real 
         estate or real estate mortgages. 
         14.      Invest in  interests  in oil,  gas, or other  mineral 
         exploration  or development  programs,  although it may invest 
         in  securities  of issuers  which  invest in or  sponsor  such 
         programs. 
         15.      Purchase   the   securities   of   other   investment 
         companies,  except  as  they  may be  acquired  as  part  of a 
         merger,   consolidation  or  acquisition  of  assets,   or  in 
         connection with a  trustee's/director's  deferred compensation 
         plan, as long as there is no duplicaton of advisory fees. 
         16.      Purchase the  securities  of  companies  which have a 
         record of less than three years'  continuous  operation if, as 
         a  result,  more  than 5% of the  value  of the  Fund's  total 
         assets would be invested in securities of such issuer. 

         
Any investment  restriction which involves a maximum percentage of securities or
assets  shall  not be  considered  to be  violated  unless  an  excess  over the
applicable  percentage occurs  immediately after and results from an acquisition
of securities or utilization of assets.


                              DIVIDENDS AND TAXES 

         
Calvert U.S.  Government  Fund and Calvert Income Fund declare and pay dividends
from net investment income on a monthly basis. Net investment income consists of
the interest  income earned  (adjusted  for  amortization  of original  issue or
market  discounts or premiums) and dividends  declared and paid on  investments,
less expenses. Distributions of net capital gains, if any, are normally declared
and paid by each Fund once a year; however,  the Funds do not intend to make any
such  distributions  from  securities  profits  unless  available  capital  loss
carryovers, if any, have been used or have expired.  Dividends and distributions
paid may differ among the classes.

Under the  backup  withholding  provisions  of the  Interest  and  Dividend  Tax
Compliance  Act of 1983,  the Fund is required to withhold 31% of any  dividends
and capital gains distributions, and 31% of each redemption transaction, if: (a)
the shareholder's social security number or other taxpayer identification number
("TIN") is not  provided or an  obviously  incorrect  TIN is  provided;  (b) the
shareholder does not certify under penalties of perjury that the TIN provided is
the shareholder's  correct TIN and that the shareholder is not subject to backup
withholding under section  3406(a)(1)(C) of the Internal Revenue Code because of
underreporting (however,  failure to provide certification as to the application
of section  3406(a)(1)(C)  will result only in backup  withholding on dividends,
not on redemptions); or (c) the Fund is notified by the Internal Revenue Service
that the TIN  provided by the  shareholder  is  incorrect or that there has been
underreporting   of  interest  or   dividends  by  the   shareholder.   Affected
shareholders  will receive  statements at least  annually  specifying the amount
withheld.

In addition,  each Fund is required under the broker reporting provisions of the
Tax  Equity  and  Fiscal  Responsibility  Act of 1982 to report to the  Internal
Revenue  Service  the  following  information  with  respect to each  redemption
transaction:  (a) the shareholder's name,  address,  account number and taxpayer
identification  number;  (b) the total dollar value of the redemptions;  and (c)
the Fund's identifying CUSIP number.

Certain shareholders are, however, exempt from the backup withholding and broker
reporting  requirements.  Exempt shareholders  include  corporations;  financial
institutions; tax-exempt organizations; individual retirement plans; the U.S., a
State,  the District of Columbia,  a U.S possession,  a foreign  government,  an
international   organization,   or  any   political   subdivision,   agency   or
instrumentality  of  any  of  the  foregoing;  U.S.  registered  commodities  or
securities  dealers;  real  estate  investment  trusts;   registered  investment
companies;  bank common trust funds; certain charitable trusts;  foreign central
banks of issue.  Non-resident  aliens also are  generally  not subject to either
requirement   but,  along  with  certain   foreign   partnerships   and  foreign
corporations,  may instead be subject to  withholding  under Section 1441 of the
Internal Revenue Code.  Shareholders  claiming exemption from backup withholding
and broker reporting should call or write the Fund for further information.

Each  Fund  intends  to  qualify  as  a  "regulated  investment  company"  under
Subchapter M of the Internal  Revenue Code. By so qualifying,  the Fund will not
be subject to federal  income taxes,  nor to excise tax under the Tax Reform Act
of 1986 (the "Act"), to the extent its earnings are distributed.

Dividends and distributions  are automatically  reinvested at net asset value in
additional   shares.   Shareholders  may  elect  to  have  their  dividends  and
distributions  paid out in cash,  or  invested  at net  asset  value in  another
Calvert Group Fund.

Distributions  from realized net short-term  capital gains, as well as dividends
from net investment  income,  are currently  taxable to shareholders as ordinary
income.

Net long-term capital gains distributions,  if any, will generally be includable
as long-term  capital gain in the gross income of shareholders  who are citizens
or residents of the United States.  Whether such realized  securities  gains and
losses are long-term or short-term depends on the period the securities are held
by the Fund, not the period for which the shareholder holds shares of the Fund.

Dividends  and  distributions  are  taxable   regardless  of  whether  they  are
reinvested  in  additional  shares of a Fund or not. A  shareholder  may also be
subject to state and local taxes on dividends and distributions  from each Fund.
Each Fund will notify  shareholders each January as to the federal tax status of
dividends  and  distributions  paid by the  Fund  and the  amount  of  dividends
withheld, if any, during the previous fiscal year.


                     CALCULATION OF YIELD AND TOTAL RETURN 

Yield 

         
Each Fund may  advertise  its "yield" from time to time.  Yield  quotations  are
calculated  separately for each class,  are historical,  and are not intended to
indicate  future  performance.  "Yield"  quotations  for each class refer to the
aggregate imputed  yield-to-maturity  of each of the Fund's investments based on
the market value as of the last day of a given  thirty-day or one-month  period,
less accrued  expenses  (net of  reimbursement  ), divided by the average  daily
number of  outstanding  shares  for that  class  which are  entitled  to receive
dividends,  times the maximum  offering  price on the last day of the period (so
that the effect of the sales charge is included in the calculation),  compounded
on a "bond  equivalent,"  or semi-annual,  basis.  Each Fund's yield by class is
computed according to the following formula:

                              Yield = 2[(a-b/cd + 1)6 - 1] 


where a = dividends  and interest  earned  during the period using the aggregate
imputed yield-to-maturity for each of the Fund's investments as noted above; b =
expenses  accrued for the period (net of  reimbursement);  c = the average daily
number of shares of that class outstanding  during the period that were entitled
to receive  dividends;  and d = the maximum offering price per share on the last
day of the period.
         
Yield will  fluctuate  in  response  to changes in  interest  rates and  general
economic  conditions,  portfolio  quality,  portfolio  maturity,  and  operating
expenses.  Yield is not fixed or insured and  therefore is not  comparable  to a
savings or other  similar  type of account.  Yield  during any  particular  time
period should not be considered an indication of future yield.  It is,  however,
useful  in  evaluating  each  Fund's   performance  in  meeting  its  investment
objective.

Total Return 

         
Each  Fund may  also  advertise  "total  return."  Total  return  is  calculated
separately  for each class.  Total return is computed by taking the total number
of shares  purchased by a hypothetical  $1,000  investment  after  deducting any
applicable  sales  charge  for  Class A shares,  adding  all  additional  shares
purchased  within  the  period  with  reinvested  dividends  and  distributions,
calculating the value of those shares at the end of the period, and dividing the
result by the initial $1,000 investment.  For periods of more than one year, the
cumulative  total  return is then  adjusted  for the  number  of  years,  taking
compounding into account,  to calculate  average annual total return during that
period.
         Total return is computed according to the following formula: 


                                P(1 + T)n = ERV 

 
where P = a  hypothetical  initial  payment of $1,000  (less the  maximum  sales
charge imposed during the period  calculated);  T = total return;  n = number of
years, and ERV = the ending  redeemable  value of a hypothetical  $1,000 payment
made at the beginning of the period.
         
Total  return is  historical  in nature and is not  intended to indicate  future
performance.  All total return  quotations  reflect the  deduction of the Fund's
maximum sales charge,  except quotations of "overall return" which do not deduct
the sales charge,  and "actual  return" which reflect  deduction of sales charge
only for those  periods when a sales charge was actually  imposed.  Thus, in the
above formula,  for overall return, P = the entire $1,000  hypothetical  initial
investment  and does not reflect the deduction of any sales  charge;  for actual
return,  P = a  hypothetical  initial  payment of $1,000  less any sales  charge
actually  imposed at the  beginning of the period for which the  performance  is
being calculated. Overall return should be considered only by investors, such as
participants  in certain pension plans, to whom the sales charge does not apply,
or for purposes of  comparison  only with  comparable  figures which also do not
reflect sales charges, such as Lipper averages.

Overall  and  total  return  for  the  Funds'  Class A  shares  for the 
periods indicated are as follows:

Total return for the Fund's  Class C shares from March 1, 1994 to September  30,
1994  was  -5.47%  and  -3.58%  for  the  Income  and  U.S.   Government  Funds,
respectively.

                                NET ASSET VALUE 

         
The net asset  value  per share of each  Fund,  the  price at which  shares  are
redeemed, is determined every business day as of 4:00 p.m., Eastern time, and at
such other times as may be appropriate or necessary.  The Funds do not determine
net asset value on certain national holidays or other days on which the New York
Stock Exchange is closed: New Year's Day, Presidents' Day, Good Friday, Memorial
Day, Independence Day, Labor Day, Thanksgiving Day, and Christmas Day.

Each Fund's net asset value per share is computed  separately  for each class by
dividing  the  value of its total  assets,  less its  liabilities,  by the total
number of shares outstanding.  Portfolio  securities are valued as follows:  (a)
securities for which market  quotations are readily  available are valued at the
most recent closing price, mean between bid and asked price, or yield equivalent
as obtained from one or more market makers for such  securities;  (b) securities
maturing within 60 days are valued at cost, plus or minus any amortized discount
or  premium,  unless  the Board of  Trustees  determines  such  method not to be
appropriate under the circumstances; and (c) all other securities and assets for
which  market  quotations  are not readily  available  are fairly  valued by the
Advisor in good faith under the supervision of the Board of Trustees.

                       PURCHASE AND REDEMPTION OF SHARES 

         
Share  certificates  will not be  issued  unless  requested  in  writing  by the
investor. No charge will be made for share certificate requests. No certificates
will be issued for fractional shares.

Amounts  redeemed  by check  redemption  may be mailed to the  investor  without
charge.  Amounts  of more than $50 and less  than  $300,000  may be  transferred
electronically  at no charge to the investor.  Amounts of $1,000 or more will be
transmitted by wire without  charge by the Fund to the  investor's  account at a
domestic  commercial bank that is a member of the Federal Reserve System or to a
correspondent  bank.  A charge of $5 is imposed on wire  transfers  of less than
$1,000.  If the investor's bank is not a Federal Reserve System member,  failure
of immediate notification to that bank by the correspondent bank could result in
a delay in crediting the funds to the investor's bank account.

Telephone  redemption  requests  which would  require the  redemption  of shares
purchased by check or electronic  funds transfer within the previous 10 business
days may not be honored.  The Fund  reserves  the right to modify the  telephone
redemption privilege.

Existing  shareholders  who at any time  desire  to  arrange  for the  telephone
redemption  procedure,  or to change  instructions  already  given,  must send a
written  notice either to the broker  through which the shares were purchased or
to the Fund with a voided check from the bank account to receive the  redemption
proceeds.  New wiring  instructions may be accompanied by a voided check in lieu
of  a  signature   guarantee.   Further   documentation  may  be  required  from
corporations, fiduciaries, pension plans, and institutional investors.
         
The Fund's  redemption check normally will be mailed to the investor on the next
business  day  following  the  date of  receipt  by the Fund of the  written  or
telephone  redemption  request.  If the investor so instructs in the  redemption
request,  the  check  will be  mailed  or the  redemption  proceeds  wired  to a
predesignated  account at the investor's bank.  Redemption proceeds are normally
paid in cash.  However,  at the sole  discretion  of the Fund,  the Fund has the
right to  redeem  shares  in  assets  other  than  cash for  redemption  amounts
exceeding,  in any 90-day  period,  $250,000 or 1% of the net asset value of the
Fund, whichever is less, or as allowed by law.

The right of  redemption  of Fund shares may be suspended or the date of payment
postponed  for any period  during  which the New York Stock  Exchange  is closed
(other than  customary  weekend and holiday  closings),  when trading on the New
York Stock Exchange is restricted,  or an emergency exists, as determined by the
Securities  and Exchange  Commission,  or if the  Commission  has ordered such a
suspension for the protection of shareholders.  Redemption proceeds are normally
mailed or wired the next  business  day but in no event  later  than  seven days
after a proper  redemption  request has been received,  unless  redemptions have
been suspended or postponed as described above.

                        REDUCED SALES CHARGES (CLASS A) 

         
Calvert  U.S.  Government  Fund and Calvert  Income Fund  impose  reduced  sales
charges  for  Class A  shares  in  certain  situations  in which  the  Principal
Underwriter   and  the  dealers  selling  Fund  shares  may  expect  to  realize
significant  economies  of scale with  respect to such sales.  Generally,  sales
costs do not increase in proportion to the dollar amount of the shares sold; the
per-dollar  transaction  cost for a sale to an  investor of shares  worth,  say,
$5,000 is generally  much higher than the  per-dollar  cost for a sale of shares
worth $1,000,000.  Thus, the applicable sales charge declines as a percentage of
the dollar amount of shares sold as the dollar amount increases.

When a  shareholder  agrees to make  purchases  of shares  over a period of time
totaling a certain dollar amount pursuant to a Letter of Intent, the Underwriter
and selling  dealers can expect to realize the economies of scale  applicable to
that stated goal amount.  Thus the Fund imposes the sales charge  applicable  to
the goal amount.  Similarly, the Underwriter and selling dealers also experience
cost savings when dealing with existing Fund shareholders,  enabling the Fund to
afford  existing  shareholders  the Right of  Accumulation.  The Underwriter and
selling dealers can also expect to realize  economies of scale when making sales
to  the  members  of  certain   qualified   groups  which  agree  to  facilitate
distribution  of Fund shares to their  members.  See "Exhibit A - Reduced  Sales
Charges" in the Prospectus.

                                  ADVERTISING 

The Fund or its affiliates may provide  information such as, but not limited to,
the economy, investment climate, investment principles,  sociological conditions
and political ambiance.  Discussion may include hypothetical  scenarios or lists
of relevant factors designed to aid the investor in determining whether the Fund
is compatible with the investor's goals. The Fund may list portfolio holdings or
give examples or securities  that may have been  considered for inclusion in the
Portfolio, whether held or not.

The Fund or its affiliates may supply comparative  performance data and rankings
from  independent  sources  such as  Donoghue's  Money  Fund  Report,  Bank Rate
Monitor,  Money,  Forbes,  Lipper  Analytical  Services,  Inc.,  CDA  Investment
Technologies,   Inc.,   Wiesenberger   Investment  Companies  Service,   Russell
2000/Small  Stock Index,  Mutual Fund Values  Morningstar  Ratings,  Mutual Fund
Forecaster,  Barron's,  The  Wall  Street  Journal,  and  Schabacker  Investment
Management,  Inc. Such averages  generally do not reflect any front- or back-end
sales charges that may be charged by Funds in that  grouping.  The Fund may also
cite to any source, whether in print or on-line, such as Bloomberg,  in order to
acknowledge origin of information.  The Fund may compare itself or its portfolio
holdings  to other  investments,  whether  or not  issued  or  regulated  by the
securities industry,  including, but not limited to, certificates of deposit and
Treasury notes. The Fund, its Advisor,  and its affiliates  reserve the right to
update performance rankings as new rankings become available.

Each of the above named trustees and officers is a trustee or officer of each of
the  investment  companies in the Calvert  Group of Funds with the  exception of
Calvert Social Investment Fund, of which only Messrs.  Baird,  Guffey, Silby and

Trustees  and  Officers  as a group own less than 1% of the  Fund's  outstanding

The Board's Audit Committee is composed of Messrs.  Baird, Blatz,  Feldman,  and
Pugh.  The  Investment  Policy  Committee is composed of Messrs.  Borts,  Diehl,
Gavian, Guffey, Rochat, Silby and Sorrell.

During fiscal 1994,  trustees of the Fund not affiliated with the Fund's Advisor
were paid $1,018 and $4,382 by Calvert U.S.  Government  Fund and Calvert Income
Fund,  respectively.  Trustees  of the Fund  not  affiliated  with  the  Advisor
presently  receive an annual fee of $20,250 for service as a member of the Board
of Trustees of the Calvert  Group of Funds,  and a fee of $750 to $1200 for each
regular Board or Committee meeting  attended;  such fees are allocated among the
respective Funds on the basis of net assets.

Trustees  of the Fund not  affiliated  with the Fund's  Advisor  ("noninterested
persons") may elect to defer receipt of all or a percentage of their annual fees
and invest them in any fund in the Calvert  Family of Funds through the Trustees
Deferred  Compensation  Plan.  Deferral of the fees is designed to maintain  the
parties  in the same  position  as if the fees  were  paid on a  current  basis.
Management  believes  this will have a negligible  effect on the Fund's  assets,
liabilities, net assets, and net income per share, and will ensure that there is
no duplication of advisory fees.


                               INVESTMENT ADVISOR 

         
The Calvert Fund's Investment Advisor is Calvert Asset Management Company, Inc.,
4550 Montgomery Avenue, Bethesda, Maryland 20814, a subsidiary of Calvert Group,
Ltd.,  which  is a  subsidiary  of  Acacia  Mutual  Life  Insurance  Company  of
Washington, D.C. ("Acacia Mutual").

The  Advisory  Contract  between The Calvert Fund and the Advisor will remain in
effect  until  January  3,  1996,  and from  year to year  thereafter,  provided
continuance  is approved at least  annually by vote of the holders of a majority
of the  outstanding  shares of the Fund or by the Board of Trustees of the Fund;
and further provided that such continuance is also approved annually by the vote
of a majority of the trustees of the Fund who are not parties to the Contract or
interested  persons of parties to the  Contract  or  interested  persons of such
parties,  cast in person at a meeting  called for the  purpose of voting on such
approval. The Contract may be terminated without penalty by either party upon 60
days' prior  written  notice;  it  automatically  terminates in the event of its
assignment.

Under the Contract,  the Advisor provides  investment advice to The Calvert Fund
and oversees the day-to-day operations,  subject to direction and control by the
Fund's Board of Trustees.  For its services,  the Advisor receives an annual fee
of 0.60% of the Calvert  U.S.  Government  Fund's  average  daily net assets and
0.70% of the average daily net assets of Calvert Income Fund.

The Advisor  provides  the Funds with  investment  advice and  research,  office
space,  administrative services,  furnishes executive and other personnel to the
Funds, pays the salaries and fees of all trustees who are affiliated  persons of
the Advisor, and pays all Fund advertising and promotional expenses. The Advisor
reserves  the  right to  compensate  broker-dealers  in  consideration  of their
promotional  or  administrative  services.  The Funds  pay all  other  operating
expenses,  including  custodial  and  transfer  agency  fees,  federal and state
securities  registration  fees, legal and audit fees, and brokerage  commissions
and other costs  associated with the purchase and sale of portfolio  securities.
However,  the  Advisor  has  agreed  to  reimburse  each  Fund for all  expenses
(excluding  brokerage,   taxes,   interest,   Distribution  Plan  expenses,  and
extraordinary items) exceeding,  on a pro rata basis, the most restrictive state
expense  limitation  in effect,  currently  2.5% of the first $30 million of the
Funds'  average  daily net assets,  2.0% of the next $70 million of such assets,
and 1.5% of such assets in excess of $100 million.

For the fiscal years ended  September  30, 1992,  1993,  and 1994,  Calvert U.S.
Government   Fund  paid  advisory  fees  of  $76,486,   $59,191,   and  $51,137,
respectively.  Calvert  Income  Fund paid  advisory  fees for the same period of
$275,176, $330,336, and $351,249, respectively.


                             METHOD OF DISTRIBUTION 

         
Each Fund has entered into an agreement with Calvert Distributors,  Inc. ("CDI")
whereby CDI, acting as principal  underwriter  for the Fund,  makes a continuous
offering of the Fund's securities on a "best efforts" basis.  Under the terms of
the agreements,  CDI is entitled to receive a distribution fee from Calvert U.S.
Government  Fund and Calvert Income Fund of 0.25% of each Fund's Class A average
daily net assets, and 1.00% of each Fund's Class C average daily net assets. For
Class A shares,  CDI also  receives the portion of the sales charge in excess of
the dealer reallowance.

For the fiscal years ended September 30, 1992 and 1993, Calvert U.S.  Government
Fund paid no Class A Distribution Plan expenses.  In 1994, the Fund paid Class A
Distribution Plan expenses of $10,102.  For the seven months ended September 30,
1994,  Class C  Distribution  Plan expenses  totaled  $807.  For the same fiscal
years,  CDI  received  net sales  charges  of  $22,264,  $22,726,  and  $14,697,
respectively.

For the fiscal years ended September 30, 1992 and 1993, Calvert Income Fund paid
no  Class  A  Distribution  Plan  expenses.  In  1994,  the  Fund  paid  Class A
Distribution Plan expenses of $29,833.  For the seven months ended September 30,
1994, Class C Distribution Plan expenses totaled $1,102.  CDI received net sales
charges of $53,757,  $69,629,  and $87,105, for the fiscal years ended September
30, 1992, 1993, and 1994, respectively.

Pursuant to Rule 12b-1  under the  Investment  Company Act of 1940,  The Calvert
Fund has adopted a Distribution Plan which permits each Fund to pay certain fees
associated with the distribution of its shares. Such fees for Class A shares may
not exceed, on an annual basis, 0.25% of the average daily net assets of Calvert
U.S.  Government Fund and Calvert Income Fund. Expenses under the Fund's Class C
Plan may not exceed,  on an annual  basis,  1.00% of the Fund's  Class C average
daily net assets.

The Calvert  Fund's  Distribution  Plans were approved by the Board of Trustees,
including  the  Trustees who are not  "interested  persons" of the Fund (as that
term is defined in the Investment Company Act of 1940) and who have no direct or
indirect  financial  interest in the operation of the Plans or in any agreements
related to the Plans.  The selection and  nomination of the Trustees who are not
interested  persons  of  the  Fund  is  committed  to  the  discretion  of  such
disinterested  Trustees.  In  establishing  the Plans,  the Trustees  considered
various  factors  including  the amount of the  distribution  fee.  The Trustees
determined that there is a reasonable likelihood that the Plans will benefit the
Fund and its shareholders.
         
The Plans may be terminated by vote of a majority of the non-interested Trustees
who have no direct or indirect  financial interest in the Plans, or by vote of a
majority  of the  outstanding  shares of the Fund.  Any change in the Plans that
would materially increase the distribution cost to the Fund requires approval of
the shareholders of the affected class;  otherwise,  the Plans may be amended by
the Trustees,  including a majority of the non-interested  Trustees as described
above.

The  Plans  will  continue  in effect  until  January  3,  1996,  if not  sooner
terminated in accordance with its terms. Thereafter,  the Plans will continue in
effect  for  successive  one-year  periods  provided  that such  continuance  is
specifically  approved by (i) the vote of a majority of the Trustees who are not
parties  to the Plans or  interested  persons  of any such party and who have no
direct or  indirect  financial  interest  in the  Plans,  and (ii) the vote of a
majority of the entire Board of Trustees.

Apart from the Plans,  the  Advisor,  at its  expense,  may incur costs 
and pay expenses associated with the distribution of shares of the Funds. 



                    TRANSFER AND SHAREHOLDER SERVICING AGENT 

         
Calvert  Shareholder  Services,  Inc., a subsidiary of Calvert Group,  Ltd., has
been retained by the Fund to act as transfer agent,  dividend  disbursing  agent
and shareholder servicing agent. These responsibilities  include:  responding to
shareholder inquiries and instructions concerning their accounts;  crediting and
debiting  shareholder  accounts for purchases and redemptions of Fund shares and
confirming  such  transactions;  updating  of  shareholder  accounts  to reflect
declaration and payment of dividends;  and preparing and distributing  quarterly
statements to shareholders regarding their accounts. For these services, Calvert
Shareholder  Services,  Inc.,  receives a fee based on the number of shareholder
accounts and the number of shareholder transactions.

For its fiscal years ended  September  30, 1992,  1993,  and 1994,  Calvert U.S.
Government  Fund  paid  Calvert  Shareholder  Services,  Inc.  fees of  $18,250,
$20,638,  and $21,123,  respectively.  For its fiscal years ended  September 30,
1992,  1993, and 1994,  Calvert Income Fund paid Calvert  Shareholder  Services,
Inc. fees of $52,638, $59,504, and $64,339, respectively.


                             PORTFOLIO TRANSACTIONS 


         
Portfolio transactions are undertaken on the basis of their desirability from an
investment  standpoint.  Investment  decisions and choice of brokers and dealers
are made by the Advisor  under the  direction  and  supervision  of the Board of
Trustees.

Each Fund's policy is to limit portfolio  turnover to transactions  necessary to
carry out its investment  policies and to obtain cash  redemption of its shares.
Depending upon market conditions, each Fund's turnover expressed as a percentage
may in some years exceed 100%, but is not expected to exceed 200%. For the years
ended  September  30, 1992,  1993,  and 1994,  the portfolio  turnover  rates of
Calvert U.S. Government Fund were 0%, 191%, and 99%, respectively. For the years
ended  September  30, 1992,  1993,  and 1994,  the portfolio  turnover  rates of
Calvert Income Fund were 18%, 25%, and 34%, respectively.

In all transactions,  the Fund seeks to obtain the best price and most favorable
execution  and  selects  broker-dealers  on  the  basis  of  their  professional
capability and the value and quality of their  services.  Broker-dealers  may be
selected who provide the Funds with statistical,  research, or other information
and  services.  Such  broker-dealers  may  receive  compensation  for  executing
portfolio   transactions   that  is  in  excess  of  the  compensation   another
broker-dealer would have received for executing such transactions if the Advisor
determines in good faith that such compensation is reasonable in relation to the
value  of the  information  or  services  provided.  Although  any  statistical,
research or other  information  or services  provided by  broker-dealers  may be
useful to the  Advisor,  its dollar value is  generally  indeterminable  and its
availability or receipt does not materially reduce the Advisor's normal research
activities or expenses.

During the fiscal years ended  September 30, 1992,  1993, and 1994, no brokerage
commissions were paid by Calvert U.S.  Government Fund or Calvert Income Fund to
broker-dealers  that provided the Fund's Advisor or Sub-Advisor with research or
other  services.  No  commissions  were paid to any  officers or trustees of The
Calvert Fund or any of their affiliates during the last three fiscal years.


                     INDEPENDENT ACCOUNTANTS AND CUSTODIANS 

         
Coopers & Lybrand,  L.L.P.,  has been selected by the Board of Trustees to serve
as  independent  accountants  for fiscal  year 1995.  State  Street Bank & Trust
Company,  N.A.,  225 Franklin  Street,  Boston,  MA 02110,  currently  serves as
custodian of the Fund's investments.  First National Bank of Maryland,  25 South
Charles Street, Baltimore, Maryland 21203 also serves as custodian of certain of
the  Fund's  cash  assets.  The  custodian  has no part in  deciding  the Fund's
investment policies or the choice of securities that are to be purchased or sold
for the Fund's Portfolios.


                              GENERAL INFORMATION 

         
The Calvert Fund (the "Trust") was organized as a  Massachusetts  business trust
on March 15,  1982.  The Calvert  Fund's  series  include  Calvert  Income Fund,
Calvert U.S.  Government  Fund,  Calvert  Short-Term U.S.  Government  Fund, and
Calvert Strategic Growth Fund. The Calvert Fund's  Declaration of Trust contains
an express  disclaimer of  shareholder  liability for acts or obligations of the
Trust. The shareholders of a Massachusetts  business trust might, however, under
certain   circumstances,   be  held  personally   liable  as  partners  for  its
obligations.   The  Declaration  of  Trust  provides  for   indemnification  and
reimbursement  of expenses out of the Trust's  assets for any  shareholder  held
personally  liable  for  obligations  of the  Trust.  The  Declaration  of Trust
provides  that the Trust shall,  upon  request,  assume the defense of any claim
made against any  shareholder for any act or obligation of the Trust and satisfy
any judgment  thereon.  The Declaration of Trust further provides that the Trust
may maintain appropriate insurance (for example, fidelity bonding and errors and
omissions  insurance)  for  the  protection  of  the  Trust,  its  shareholders,
trustees,  officers,  employees  and  agents  to cover  possible  tort and other
liabilities. Thus, the risk of a shareholder incurring financial loss on account
of shareholder  liability is limited to  circumstances  in which both inadequate
insurance exists and the Trust itself is unable to meet its obligations.
         
Each share of each series  represents  an equal  proportionate  interest in that
series with each other share and is entitled to such dividends and distributions
out of the income  belonging to such series as declared by the Board.  The Funds
offers  two  separate  classes  of  shares:  Class A and  Class  C.  Each  class
represents  interests  in the same  portfolio  of  investments  but,  as further
described in the  prospectus,  each class is subject to differing  sales charges
and expenses,  which  differences  will result in differing net asset values and
distributions. Upon any liquidation of the Funds, shareholders of each class are
entitled to share pro rata in the net assets  belonging to that series available
for distribution.
         
The Funds  will send  shareholders  confirmations  of  purchase  and  redemption
transactions,   as  well  as  periodic  transaction   statements  and  unaudited
semi-annual  and audited annual  financial  statements of the Funds'  investment
securities,  assets and  liabilities,  income and  expenses,  and changes in net
assets.
         
The Prospectus  and this Statement of Additional  Information do not contain all
the  information  in  the  Trust's  registration  statement.   The  registration
statement  is on  file  with  the  Securities  and  Exchange  Commission  and is
available to the public.


                              FINANCIAL STATEMENTS 

         
Each  Fund's  audited  financial  statements  included  in its Annual  Report to
Shareholders  dated September 30, 1994, are expressly  incorporated by reference
and  made a part of this  Statement  of  Additional  Information.  A copy of the
Annual  Report may be obtained  free of charge by writing or calling The Calvert
Fund.


                                    APPENDIX 

                                LETTER OF INTENT 

Date

Calvert Distributors, Inc. 
4550 Montgomery Avenue 
Bethesda, MD 20814 

Ladies and Gentlemen: 

By signing this Letter of Intent, or affirmatively  marking the Letter of Intent
option on my Fund Account Application Form, I agree to be bound by the terms and
conditions  applicable to Letters of Intent  appearing in the Prospectus and the
Statement of Additional  Information  for the Fund and the provisions  described
below as they may be amended from time to time by the Fund. Such amendments will
apply automatically to existing Letters of Intent.

I intend  to  invest in the  shares  of:  (Fund or  Portfolio  name*)during  the
thirteen (13) month period from the date of my first  purchase  pursuant to this
Letter  (which  cannot be more than  ninety  (90) days prior to the date of this
Letter  or my Fund  Account  Application  Form,  whichever  is  applicable),  an
aggregate  amount  (excluding any  reinvestments of  distributions)  of at least
fifty thousand dollars ($50,000) which, together with my current holdings of the
Fund  (at  public  offering  price  on date of this  Letter  or my Fund  Account
Application  Form,  whichever  is  applicable),  will equal or exceed the amount
checked below:

         __ $50,000  __ $100,000  __ $250,000  __ $500,000  __ $1,000,000 


*"Fund" in this Letter of Intent shall refer to the Fund or Portfolio, as the  
case may be, here indicated. 


Subject to the conditions  specified  below,  including the terms of escrow,  to
which I hereby agree, each purchase occurring after the date of this Letter will
be made at the public offering price  applicable to a single  transaction of the
dollar amount specified above, as described in the Fund's prospectus. No portion
of the sales charge  imposed on purchases  made prior to the date of this Letter
will be refunded.

I am making  no  commitment  to  purchase  shares,  but if my  purchases  within
thirteen  months from the date of my first purchase do not aggregate the minimum
amount  specified  above,  I will pay the  increased  amount  of  sales  charges
prescribed in the terms of escrow  described  below. I understand  that 4.75% of
the minimum dollar amount  specified above will be held in escrow in the form of
shares  (computed to the nearest full share).  These shares will be held subject
to the terms of escrow described below.
From the initial purchase (or subsequent  purchases if necessary),  4.75% of the
dollar amount  specified in this Letter shall be held in escrow in shares of the
Fund by the Fund's transfer agent. For example,  if the minimum amount specified
under the Letter is $50,000,  the escrow shall be shares valued in the amount of
$2,375 (computed at the public offering price adjusted for a $50,000  purchase).
All dividends and any capital gains  distribution on the escrowed shares will be
credited to my account.
If the total minimum investment specified under the Letter is completed within a
thirteen month period, escrowed shares will be promptly released to me. However,
shares  disposed of prior to  completion of the purchase  requirement  under the
Letter will be deducted  from the amount  required  to complete  the  investment
commitment.

Upon expiration of this Letter,  the total purchases  pursuant to the Letter are
less  than  the  amount  specified  in  the  Letter  as the  intended  aggregate
purchases,  Calvert Distributors,  Inc. ("CDI") will bill me for an amount equal
to the  difference  between the lower load I paid and the dollar amount of sales
charges which I would have paid if the total amount purchased had been made at a
single  time.  If not paid by the  investor  within 20 days,  CDI will debit the
difference from my account.  Full shares, if any,  remaining in escrow after the
aforementioned adjustment will be released and, upon request, remitted to me.
         
I irrevocably constitute and appoint CDI as my attorney-in-fact, with full power
of  substitution,  to surrender for redemption any or all escrowed shares on the
books of the Fund. This power of attorney is coupled with an interest.
        
The commission allowed by Calvert Distributors,  Inc. to the broker-dealer named
herein  shall be at the rate  applicable  to the minimum  amount of my specified
intended purchases.
         
The  Letter may be revised  upward by me at any time  during the  thirteen-month
period,  and such a revision  will be treated as a new  Letter,  except that the
thirteen-month  period  during  which  the  purchase  must be made  will  remain
unchanged and there will be no  retroactive  reduction of the sales charges paid
on prior purchases. In determining the total amount of purchases made hereunder,
shares disposed of prior to termination of this Letter will be deducted. My
broker-dealer shall refer to this Letter of Intent in placing any future  
purchase orders for me while this Letter is in effect.

           Statement of Additional Information dated January 31, 1995 

                     Date of Supplement: September 30, 1995

Any previous reference to the Income Fund's Investment Restrictions are  
replaced by the following: 

FUNDAMENTAL INVESTMENT RESTRICTIONS 

         The Calvert Income Fund ("Fund") has adopted the following investment  
restrictions which cannot be changed without the approval of the holders of a  
majority of the outstanding shares of the Fund.  As defined in the Investment  
Company Act of 1940, this means the lesser of the vote of (a) 67% of the  
shares of the Fund at a meeting where more than 50% of the outstanding shares  
of the Fund are represented. 

         The Fund may not: 

         (1)      With respect to 75% of the Funds assets, purchase securities  
                  of any issuer (other than obligations of, or guaranteed by,  
                  the United States Government, its agencies or  
                  instrumentalities) if, as a result, more than 5% of the  
                  value of the Fund's total assets would be invested in  
                  securities of such issuer. 

         (2)      Concentrate more than 25% of the value of its assets in any  
                  one industry; provided, however, that there is no limitation  
                  with respect to investments in obligations issued or  
                  guaranteed by the United States Government or its agencies  
                  and instrumentalities. 

         (3)      With respect to 75% of the Funds assets, purchase more than  
                  10% of the outstanding voting securities of any issuer.  In  
                  addition, all series of the Calvert Fund may not together  
                  purchase more than 10% of the outstanding voting securities  
                  of any issuer. 

         (4)      Make loans (other than loans of its portfolio securities,  
                  loans through the purchase of money market instruments and  
                  repurchase agreements, or loans through the purchase of  
                  goods, debentures or other debt securities of the types  
                  commonly offered privately and purchased by financial  
                  institutions).  The purchase of a portion of an issue of  
                  publicly distributed debt obligations shall not constitute  
                  the making of loans. 

         (5)      Underwrite the securities of other issuers. 

         (6)      Purchase from or sell to any of the Funds Officers or  
                  Trustees, or firms of which any of them are members, any  
                  securities (other than capital stock of the Fund), but such  
                  persons or firms may act as brokers for the Fund. 

         (7)      Issue senior securities or borrow money except from banks as  
                  a temporary measure for extraordinary or emergency purposes  
                  and then only in an amount up to 10% of the value of its  
                  total assets in order to meet redemption requests without  
                  immediately selling portfolio securities.  The writing of  
                  covered call options is not considered issuing a senior  
                  security.  In order to secure any such borrowing under this  
                  section, the Fund may pledge, mortgage or hypothecate its  
                  assets and then in an amount not greater than 15% of the  
                  value of its total assets.  The Fund will not borrow for  
                  leverage purposes and investment securities will not be  
                  purchased while any borrowings are outstanding. 

         (8)      Purchase or retain the securities of any issuer if any  
                  Officer or Trustee of the Fund or its Investment Adviser  
                  owns beneficially more than 1/2 of 1% of the securities of  
                  such issuer or if together such individuals own more than 5%  
                  of the securities of such issuer. 

         (9)      Invest in interests in oil, gas, or other mineral,  
                  exploration or development programs, although it may invest  
                  in securities of issuers which invest in or sponsor such  
                  programs. 

         (10)     Purchase the securities of other investment companies,  
                  except as they may be acquired as part of a merger,  
                  consolidation or acquisition of assets, or in connection  
                  with a trustee's/director's deferred compensation plan, as  
                  long as there is no duplication of advisory fees. 

         (11)     Purchase the securities of companies which have a record of  
                  less than three years' continuous operation if, as a result,  
                  more than 5% of the value of the Funds' total assets would  
                  be invested in securities of such issuer. 


         (12)     Purchase or sell physical commodities except that it may  
                  enter into futures contracts and options thereon. 

         (13)     Invest in real estate, although it may invest in securities  
                  which are secured by real estate or real estate mortgages  
                  and may invest in the securities of issuers which invest or  
                  deal in real estate or real estate mortgages. 

NONFUNDAMENTAL INVESTMENT RESTRICTIONS 

         The Fund has adopted the following operation (i.e.,  
non-fundamental) investment policies and restrictions which may be  
changed by the Board of Trustees without shareholder approval.  The  
Fund may not: 

         (1)      Purchase a futures contract or an option thereon  
                  if, with respect to positions in futures or options  
                  on futures which do not represent bonafide hedging,  
                  the aggregate initial margin and premiums on such  
                  options would exceed 5% of the Fund's net asset  
                  value. 

         (2)      Invest in pots, calls, straddles, spread, or any  
                  combination thereof, except to the extent permitted  
                  by the Prospectus and Statement of Additional  
                  Information, as each may from time to time be  
                  amended. 

         (3)      Effect short sales or securities, except if it owns  
                  or has the right to obtain securities equivalent in  
                  kind and amount to the securities sold short.  For  
                  purposes of this restriction, transactions in  
                  futures contracts and options are not deemed to  
                  constitute selling securities short. 


         (4)      Purchase securities on margin, except (1) for use
