Quick Tool Overview

The Bond Calculator solves in both directions: price from a required yield, or yield to maturity from a price. It reports current yield alongside YTM and explains whether the bond is trading at a premium or a discount, and why.

About the Bond Calculator

Enter the face value, coupon rate, years to maturity and either the price or the required yield, and the calculator returns the other along with current yield, total coupon income and whether the bond trades at a premium or a discount.

Bond prices move inversely to interest rates, and this calculator is the clearest way to see why. A bond paying a five percent coupon in a market demanding seven must sell below face value, because the discount is what makes up the shortfall in income. Yield to maturity is the figure that captures both the coupons and that price movement, which is why it is the standard comparison measure and why current yield, which ignores the capital element entirely, can be seriously misleading on a bond bought away from par.

Key features of the Bond Calculator

Price or yield, either way

Enter a market yield to get the price, or a price to get the yield to maturity.

YTM against current yield

Current yield ignores the pull to par entirely, which makes it misleading on any bond bought away from face value.

Premium and discount explained

Why a five percent coupon must sell below par in a seven percent market, shown rather than asserted.

Coupon frequency

Annual, semi-annual or quarterly, which changes both the price and the effective yield.

Total income reported

Coupons over the life of the bond plus the capital gain or loss at maturity.
