# YIELDMAT function

The `YIELDMAT` function calculates the annual yield of a security paying interest at maturity, based on price.

### Parts of a YIELDMAT formula

The `YIELDMAT` formula is formatted as `=YIELDMAT(settlement, maturity, issue, rate, price, [day_count_convention]).`

 Part Description Notes `settlement` The settlement date of the security, the date after issuance when the security is delivered to the buyer. `maturity` The maturity or end date of the security, when it can be redeemed at face or par value. `issue` The date the security was initially issued. `rate` The annualized rate of interest. `price` The price at which the security is bought. `day_count_convention` An indicator of what day count method to use. Optional - 0 by default. 0 indicates U.S. (NASD) 30/360 - This assumes 30-day months and 360-day years as per the National Association of Securities Dealers standard and performs specific adjustments to entered dates which fall at the end of months. 1 indicates Actual/Actual - This calculates based upon the actual number of days between the specified dates and the actual number of days in the intervening years. Used for U.S. Treasury Bonds and Bills, but also the most relevant for non-financial use. 2 indicates Actual/360 - This calculates based on the actual number of days between the specified dates, but assumes a 360-day year. 3 indicates Actual/365 - This calculates based on the actual number of days between the specified dates, but assumes a 365-day year. 4 indicates European 30/360 - Similar to `0`, this calculates based on a 30-day month and 360-day year, but adjusts end-of-month dates according to European financial conventions.

### Sample formulas

`YIELDMAT(DATE(2010,01,02),DATE(2039,12,31),DATE(2010,01,01),3,100.47)`

`YIELDMAT(A2,B2,C2,D2,E2,1)`

### Notes

• `settlement`, `maturity`, and `issue` should be entered using `DATE`, `TO_DATE`, or other date parsing functions rather than by entering text.
