• 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.

Note

Visual Basic for Applications (VBA) calculates serial dates differently than Excel. In VBA, serial number 1 is December 31, 1899, rather than January 1, 1900.

• Issue, maturity, and basis are truncated to integers.

• If issue or maturity is not a valid date, ACCRINTM will generate an error.

• If rate ? 0 or if par ? 0, ACCRINTM will generate an error.

• If basis < 0 or if basis > 4, ACCRINTM will generate an error.

• If issue ? maturity, ACCRINTM will generate an error.

• ACCRINTM is calculated as follows: where: 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.
