## General Process

Solving the mathematical formula for YTM is cumbersome and difficult, but the calculation is simple with a financial calculator. Information about the current price, face value, years to maturity, and coupon rate or coupon payment are entered into the calculator’s *time value of money* functions. Solving for the interest rate provides the yield to maturity.

## Example

Consider a bond selling for $857 (PV) with a semi-annual coupon payment of $25 (PMT), a $1,000 face value (FV), and 20 semi-annual periods (N) until maturity. Calculate the yield to maturity for this bond using the time value of money keys on a financial calculator and solving for the interest rate (I) of 3.507%. In this case, the interest rate is the semi-annual rate and can be multiplied by two for an annual rate of 7.01%.
