The ACCRINTM function in Excel is a powerful tool used to calculate the accrued interest for a security that pays interest at maturity. It’s particularly useful for investments like bonds, which often have interest payments at specific intervals.


The syntax for ACCRINTM is:

=ACCRINTM(issue, settlement, rate, par, [basis])

Parameters Explanation:

Issue Date (issue): This is the date when the security was issued.

Settlement Date (settlement): The date when the security is purchased. It can be after the issue date.

Annual Coupon Rate (rate): The annual interest rate of the security.

Par Value (par): The face value of the security.

[Basis]: This argument is optional and determines the day count basis to use in the calculation. Excel provides various basis options (0, 1, 2, 3, etc.), each with its own method for calculating the number of days between dates.

How to Use ACCRINTM:

Let’s go through an example to demonstrate how to use the ACCRINTM function.

Suppose we have a bond that was issued on January 1, 2023, with a settlement date of July 1, 2023. The annual coupon rate is 5%, and the par value of the bond is $1,000.

In Excel, you would input the following formula:

=ACCRINTM(“1/1/2023”, “7/1/2023”, 0.05, 1000) or =ACCRINTM(E4,E5,E6,E7,E8)

If you want to specify the day count basis, you can add it as the fifth argument:

=ACCRINTM(“1/1/2023”, “7/1/2023”, 0.05, 1000, 0)

Press enter to compute the results

Tips for Effective Usage:

Dates Format: Ensure the dates are in a recognizable format (e.g., Excel date format or entered as a date using quotation marks).

Interest Rate Format: Input the annual interest rate as a decimal (e.g., 5% as 0.05).

Par Value: Enter the par value of the security.

Understanding Basis: Different basis values affect the calculation, so choose the appropriate basis for your scenario.

Key Considerations:

  • ACCRINTM assumes a 360-day year and 30-day month convention.
  • The settlement date must be later than the issue date.
  • Check the accuracy of your inputs (dates, rates, par value) to get precise results.


The ACCRINTM function in Excel is an essential tool for financial analysis, especially in evaluating accrued interest for fixed-income securities like bonds. By providing issue date, settlement date, rate, and par value, alongside an optional day count basis, it helps in calculating accrued interest accurately.

Remember, proper understanding and input of the function’s parameters are crucial for obtaining correct results. This function streamlines interest calculations, making it a valuable asset for financial analysts, investors, and anyone dealing with fixed-income investments in Excel.
