Bond YTM calculator

Price, coupon and maturity in — one annualised yield out. Your numbers, no feed.

Half-yearly coupons, nominal half-yearly compounding (G-sec convention). Enter your own coupon — never a quoted yield.

7.00% YTM

  • Price you pay₹1,00,000
  • Face at maturity₹1,00,000
  • Annual coupon cash₹7,000

Discount (price below face) lifts YTM above the coupon; premium pulls it below. Coupons are pre-tax — interest is taxed at slab.

What this calculator answers

A ₹1,00,000-face bond with a 7% coupon and 10 years left, bought at face value, yields 7.00% to maturity. Enter the face, coupon, years and the price you pay to see the annualised yield.

How it is calculated

Each half-yearly coupon plus the face at maturity is discounted at the solved yield (nominal half-yearly compounding, the G-sec convention) until the present value equals the price — solved by bisection to two decimals.

Clean price (no accrued interest); coupons pre-tax since interest is taxed at slab. Your coupon is an assumption, never a quoted yield.

Common questions

Why is my YTM above the coupon?

A discount price (below face) lifts the yield above the coupon; a premium price pulls it below. At face value the two match exactly.

Does this use live prices?

No. There is no bond-price feed here — you enter the price, so the yield is only as honest as your input.

YTM or coupon — which decides?

YTM: it folds price, coupons and maturity into one annualised number. A high coupon at a steep premium can still be a poor yield.
