Arg1RequiredVariantThe security's issue date.
Arg2RequiredVariantThe security's maturity date.
Arg3RequiredVariantThe security's annual coupon rate.
Arg4RequiredVariantThe security's par value. If you omit par, ACCRINTM uses \$1,000.
Arg5OptionalVariantThe type of day count basis to use.

### The following list contains information to be aware of when working with ACCRINTM

• 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, 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.
