How to calculate bond yield measures
- Enter face value and the annual coupon rate.
- Enter the market price you are evaluating.
- Enter years remaining until maturity.
- Read current yield, approximate YTM, annual coupon, and premium or discount.
- Treat approximate YTM as a shortcut, not a full IRR solve or investment advice.
Bond yield measures
Current yield and approximate YTM from price
| Current yield | Annual coupon / market price |
|---|---|
| Annual coupon | face × (coupon% / 100) |
| Approx YTM | (C + (F − P)/n) / ((F + P)/2) |
| Premium / discount | price − face |
| Not included | Exact IRR root, accrued interest, call yield |

What this yield page reports
Given a typed market price, this page reports current yield and an approximate yield to maturity. It does not solve an IRR root on every cash flow. For pricing from a typed yield instead, use the bond price page.
Formulas used
Current yield = annual coupon / price, with annual coupon = face × coupon rate. Approximate YTM = (annual coupon + (face − price) / years) / ((face + price) / 2). Premium or discount is price minus face.

Clean price from a typed yield is on bond price and bond. Effective annual rate from nominal compounding sits on APR to APY.
Use cases
Compare current yield on a discount bond versus a premium bond. Rough approximate YTM for homework. See how far price sits from face. Not a trading signal.
Worked example
Face $1,000, 5% coupon, price $950, 10 years. Annual coupon is $50. Current yield is 50 / 950 ≈ 5.26%. Approximate YTM uses the average-price formula and sits a bit above current yield because the bond also returns toward face.
