ACCRINT function

Returns the accrued interest for a security that pays periodic interest.



Important   Dates should be entered by using the DATE function, or as results of other formulas or functions. For example, use DATE(2008,5,23) for the 23rd day of May, 2008. Problems can occur if dates are entered as text.

Issue     is the security's issue date.

First_interest     is the security's first interest date.

Settlement     is the security's settlement date. The security settlement date is the date after the issue date when the security is traded to the buyer.

Rate     is the security's annual coupon rate.

Par     is the security's par value. If you omit par, ACCRINT uses $1,000.

Frequency     is the number of coupon payments per year. For annual payments, frequency = 1; for semiannual, frequency = 2; for quarterly, frequency = 4.

Basis     is the type of day count basis to use.


Day count basis

0 or omitted

US (NASD) 30/360








European 30/360

Calc_method    Calc_method is a logical value that specifies the way to calculate the total accrued interest when the date of settlement is later than the date of first_interest. A value of TRUE (1) returns the total accrued interest from issue to settlement. A value of FALSE (0) returns the accrued interest from first_interest to settlement. If you do not enter the argument, it defaults to TRUE.


  • Microsoft Office Excel stores dates as sequential serial numbers so they can be used in calculations. By default, January 1, 1900 is serial number 1, and January 1, 2008 is serial number 39448 because it is 39,448 days after January 1, 1900. Microsoft Office Excel for the Macintosh uses a different date system as its default.

  • Issue, first_interest, settlement, frequency, and basis are truncated to integers.

  • If issue, first_interest, or settlement is not a valid date, ACCRINT returns the #VALUE! error value.

  • If rate ≤ 0 or if par ≤ 0, ACCRINT returns the #NUM! error value.

  • If frequency is any number other than 1, 2, or 4, ACCRINT returns the #NUM! error value.

  • If basis < 0 or if basis > 4, ACCRINT returns the #NUM! error value.

  • If issue ≥ settlement, ACCRINT returns the #NUM! error value.

  • ACCRINT is calculated as follows:



    Ai = number of accrued days for the ith quasi-coupon period within odd period.

    NC = number of quasi-coupon periods that fit in odd period. If this number contains a fraction, raise it to the next whole number.

    NLi = normal length in days of the ith quasi-coupon period within odd period.
