## Bond Yield to Maturity Definition

The bond yield to maturity (abbreviated as Bond YTM) is the internal rate of return earned by an investor who buys the bond today at the market price, assuming that the bond will be held until maturity, and that all coupon and principal payments will be made on schedule.

## Calculating Bond Yield to Maturity

The equation for Yield to Maturity (YTM) is as following, where c is the annual coupon payment, Y is the number of years to maturity, r is the YTM, B is the par value of the bond and P is the price of the bond:

c × (1 + r)^{-1} + c × (1 + r)^{-2} + . . . + c × (1 + r)^{-Y} + B × (1 + r)^{-Y} = P
