Power Pivot Principles: The A to Z of DAX Functions – ACCRINT

15 February 2022

In our long-established Power Pivot Principles articles, we continue our series on the A to Z of Data Analysis eXpression (DAX) functions. This week, we look at ACCRINT.

The ACCRINT function

The ACCRINT function returns the accrued interest for a security that pays interest on a periodic basis.  It uses the following syntax:

=ACCRINT(issue_date, first_interest_date, settlement_date, rate, par, frequency, [basis], [calculation_method])

Please note both basis and calculation method is optional, which is why they appear in square brackets (don’t add the square brackets!).

The arguments are defined as follows:

  • issue_date: this is required and represents the issue date of the security
  • first_interest_date: also required; this is the initial date of interest
  • settlement_date: again mandatory, this is the date after the issue date when the security is traded to the buyer
  • rate: this is required too and is the security’s annual coupon rate (be careful this is entered correctly)
  • par: another necessary argument, this is the security’s par value, which is the face value of a share or other security rather than its market value
  • frequency: the final required option, this represents number of coupon payments per year.  For annual payments, frequency = 1; for semi-annually, frequency = 2; for quarterly, frequency = 4.  In other words, calculate based on 12 (number of months in year) divided by the duration (in months) between payments
  • basis: this is an optional argument (assumed to be zero [0] if omitted).  There are five options:
Basis Day count basis
0 or omitted US (NASD) 30 / 360
1 Actual / actual
2 Actual / 360
3 Actual / 365
4 European 30 / 360
  • calculation_method: again optional, this value determines the way to calculate the total accrued interest when the date of settlement is after the first_interest_date. A value of TRUE (1) returns the total accrued interest from issue_date to settlement_date. A value of FALSE (0) returns the accrued interest from first_interest_date to settlement_date. As mentioned, this argument is optional; if not specified, the default value is TRUE.

It should be noted that:

  • dates are stored as sequential serial numbers so they can be used in calculations. In DAX, December 30, 1899 is day zero [0], and January 1, 2008 is 39448 because it is 39,448 days after December 30, 1899
  • ACCRINT is calculated as follows:


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

                     o NC = number of quasi-coupon periods that fit in the odd period. If this number contains a fraction, it is raised to the next whole number (i.e. it is rounded up)

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

  • issue_date, first_interest_date and settlement_date are truncated to integers
  • frequency and basis are rounded to the nearest integer
  • an error is returned if:

                     o issue_date, first_interest_date or settlement_date is / are not (a) valid date(s)

                     o issue_date ≥ settlement_date

                     o rate ≤ 0

                     o par ≤ 0

                     o frequency is any number other than 1, 2 or 4

                     o basis < 0 or basis > 4

  • this function is not supported for use in DirectQuery mode when used in calculated columns or row-level security (RLS) rules.

Please see my examples below:

returns the accrued interest of 116.94, from issue_date to settlement_date, for a security with the terms specified above.

returns the accrued interest of 66.94, from first_interest_date to settlement_date, for a security with the terms specified above.
