Three yields, three answers

Coupon yield is the rate printed on the bond. Current yield is the coupon divided by what you actually paid. Yield to maturity adds the capital gain or loss you will realise at redemption, spread over the remaining years — and it is the only one of the three that lets you compare two bonds bought at different prices.

The formula

Approx YTM = (coupon + (face − price)/years) ÷ ((face + price)/2)

Every result on this page comes from this formula. Nothing is rounded until the final display, so figures match a spreadsheet to the cent.

How to use the Bond Yield Calculator

  1. Fill in each field with your own figures — the defaults are only there as an example.
  2. The result updates as you type, so there is no button to press.
  3. Check the breakdown under the main result for the supporting numbers.
  4. Use the copy button to take the result with you, or share the link to reload the same inputs.
