The following functions are similar to `YIELDDISC` or are often used with it in a formula:

• `YIELD`

The YIELD function calculates the yield of a security that pays periodic interest. The yield is the annualized percentage rate returned on the bond, assuming the bond is held until maturity. This function is commonly used in finance and investment analysis.

• `PRICE`

The `PRICE` function calculates the price per \$100 face value of a security that pays periodic interest. It is commonly used to determine the current value of a bond. The function takes the settlement date, maturity date, annual coupon rate, yield, redemption value, and frequency of coupon payments as input. It returns the price of the security, which is the sum of the present value of the coupon payments and the present value of the redemption value.

• `DURATION`

The `DURATION` function calculates the Macauley duration of a security paying periodic interest, such as a US Treasury Bond, based on expected yield. The Macauley duration is a measure of the sensitivity of the price of the security to changes in interest rates. This function is commonly used in finance and investment analysis.

• `ACCRINT`

The `ACCRINT` function calculates the accrued interest of a security that pays periodic interest. It is commonly used in financial analysis to determine the amount of interest earned but not yet paid on a security. The function takes into account the issue date, first payment date, settlement date, rate, redemption value, and frequency of interest payments. The result is the accrued interest at the settlement date.

• `TBILLYIELD`

The `TBILLYIELD` function calculates the yield of a Treasury bill based on its price. It returns the annual yield of a Treasury bill (a type of short-term government security), based on its price, maturity, and settlement dates. This function is commonly used in financial analysis to compare the yield of Treasury bills with other types of investments.
