This article describes the formula syntax and usage of the ACCRINTM function (function: A prewritten formula that takes a value or values, performs an operation, and returns a value or values. Use functions to simplify and shorten formulas on a worksheet, especially those that perform lengthy or complex calculations.) in Microsoft Excel.
Returns the accrued interest for a security that pays interest at maturity.
ACCRINTM(issue, settlement, rate, par, [basis])
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.
The ACCRINTM function syntax has the following arguments (argument: A value that provides information to an action, an event, a method, a property, a function, or a procedure.):
- Issue Required. The security's issue date.
- Settlement Required. The security's maturity date.
- Rate Required. The security's annual coupon rate.
- Par Required. The security's par value. If you omit par, ACCRINTM uses $1,000.
- Basis Optional. The type of day count basis to use.
||Day count basis
|0 or omitted
||US (NASD) 30/360
- Microsoft 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.
- Issue, settlement, and basis are truncated to integers.
- If issue or settlement is not a valid date, ACCRINTM returns the #VALUE! error value.
- If rate ≤ 0 or if par ≤ 0, ACCRINTM returns the #NUM! error value.
- If basis < 0 or if basis > 4, ACCRINTM returns the #NUM! error value.
- If issue ≥ settlement, ACCRINTM returns the #NUM! error value.
- ACCRINTM is calculated as follows:
ACCRINTM = par x rate x A/D
- A = Number of accrued days counted according to a monthly basis. For interest at maturity items, the number of days from the issue date to the maturity date is used.
- D = Annual Year Basis.
