Price of a bond

Find what a bond is worth today, given its coupon and the yield you want.

Open in Trident

A bond pays a fixed coupon twice a year and returns its face value (100) at the end. Its price today is all those payments discounted at the yield you require. If the coupon is below your required yield, the price is below 100.

Example: a 6% bond maturing in exactly 10 years from the settlement date, with an 8% required yield, priced per 100 of face value.
