About COUPNUM 🔗

Use the COUPNUM function in Excel to determine the number of coupon payments expected between two dates. This is useful for analyzing fixed-income securities and other interest-bearing investments. Input the settlement date, maturity date, frequency of coupon payments, and the day-count basis. The function calculates the number of coupons to be paid in the specified period, aiding in financial planning.

Examples 🔗

If you've acquired a bond with a semi-annual coupon payment frequency and a maturity date of December 31, 2025, and the settlement date is July 1, 2023, use the following COUPNUM formula to determine the number of coupon payments: =COUPNUM("07/01/2023", "12/31/2025", 2, 0). This will return the count of coupon payments from the settlement date to the maturity date.

For a security with quarterly coupon payments and a maturity date of May 15, 2024, with a settlement date of February 15, 2022, use this COUPNUM formula: =COUPNUM("02/15/2022", "05/15/2024", 4, 0). This will provide the number of coupon payments between the specified dates.

Notes 🔗

Use the COUPNUM function with valid Excel date values or references to cells containing date values. This function assumes a regular schedule for coupon payments and does not support securities with irregular payment dates. Adjust the function parameters based on your investment's specifics to ensure accurate results.
