MS Excel: COUPNCD function for coupon date

The COUPNCD function in Excel returns the next coupon date after the settlement date of a bond.In simple words, it helps you find out when the bond will make its next interest payment after you purchase it.

This function is very helpful in bond investment calculations, pricing, and financial reporting.

Syntax

COUPNCD(settlement, maturity, frequency, [basis])

Argument	Description
settlement	The date when the bond is purchased (settlement date).
maturity	The bond's maturity date (final payment date).
frequency	Number of coupon payments per year: 1 = Annual 2 = Semi-Annual 4 = Quarterly
basis (Optional)	Day count basis: 0 = US (NASD) 30/360 (default) 1 = Actual/Actual 2 = Actual/360 3 = Actual/365 4 = European 30/360

Key Points

• Returns the exact date of the next coupon payment after settlement.

• Critical for accrued interest, bond pricing, and investment decisions.

• You must format the result cell as a date to properly see the output.

• The basis affects only how interest is calculated, not the coupon date itself.

Practical Example

Suppose you purchase a bond on April 15, 2024, that matures on April 15, 2028.The bond pays interest semi-annually (2 times a year) using the 30/360 basis.

The formula:

=COUPNCD(DATE(2024,4,15), DATE(2028,4,15), 2, 0)

Result:October 15, 2024

Explanation:Since the bond pays every 6 months and you purchased it on April 15, 2024 (the start of the period), the next coupon payment will be 6 months later, on October 15, 2024.

Another example:Settlement on May 1, 2024 instead:

=COUPNCD(DATE(2024,5,1), DATE(2028,4,15), 2, 0)

Result:October 15, 2024

Even though you purchased it after the April coupon date, the next coupon remains October 15, 2024.

Maturity Date	15-Apr-2028
