YIELDMAT function: Description, Usage, Syntax, Examples and Explanation

What is YIELDMAT function in Excel?

YIELDMAT function is one of the Financial functions in Microsoft Excel that returns the annual yield of a security that pays interest at maturity.

YIELDMAT(settlement, maturity, issue, rate, pr, [basis])

The YIELDMAT function syntax has the following arguments:

Settlement: The security’s settlement date. The security settlement date is the date after the issue date when the security is traded to the buyer.
Maturity: The security’s maturity date. The maturity date is the date when the security expires.
Issue: The security’s issue date, expressed as a serial date number.
Rate: The security’s interest rate at date of issue.
Pr: The security’s price per $100 face value.
Basis(Optional): The type of day count basis to use.

Note: Problems can occur if dates are entered as text. Therefore, all dates should be entered by using the DATE function, or formatted as date under format cell to avoid errors.

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.
The settlement date is the date a buyer purchases a coupon, such as a bond. The maturity date is the date when a coupon expires. For example, suppose a 30-year bond is issued on January 1, 2008, and is purchased by a buyer six months later. The issue date would be January 1, 2008, the settlement date would be July 1, 2008, and the maturity date would be January 1, 2038, which is 30 years after the January 1, 2008, issue date.
Settlement, maturity, issue, and basis are truncated to integers.
If settlement, maturity, or issue is not a valid date, YIELDMAT returns the #VALUE! error value.
If rate < 0 or if pr ≤ 0, YIELDMAT returns the #NUM! error value.
If basis < 0 or if basis > 4, YIELDMAT returns the #NUM! error value.
If settlement ≥ maturity, YIELDMAT returns the #NUM! error value.
