Bond Yield Calculator

Calculate a bond's current yield, yield to maturity and yield to call from its face value, coupon rate, market price and time remaining.

What this means

  • Trading at a discount — yield to maturity is above the coupon rate.
  • Discounting every coupon and the $1,000.00 redemption at 6.694% gives a price of $950.00, which matches the $950.00 you entered — that is the convergence check on the solver.
  • Enter a call price and years to call below to add yield to call.

Call provision (optional)

Yield to maturity is solved by bisection on the discounted cash flow price equation, capped at 200 iterations, so it always terminates. Assumes whole coupon periods, coupons reinvested at the yield, and no accrued interest or tax. No bond data is fetched — every input is yours. Estimates only, not investment advice.

What is the Bond Yield Calculator?

The ByteTools Bond Yield Calculator works out what a bond actually returns at the price you can buy it for.

  • Current yield, yield to maturity and yield to call in one view
  • YTM solved by bisection on the price equation — no approximation formula
  • Any coupon frequency: annual, semi-annual, quarterly or monthly
  • Premium, par and discount bonds all flagged clearly
  • Shows the theoretical price at the solved yield as a self-check
  • No bond data feeds; every input is yours and stays in your browser

How to use the Bond Yield Calculator

  1. 1

    Enter the bond's face (par) value and its annual coupon rate.

  2. 2

    Type the current market price you can buy it at.

  3. 3

    Set the years remaining to maturity and the coupon payments per year.

  4. 4

    Read the current yield, yield to maturity and the price check.

  5. 5

    Optionally add a call price and years to call to see the yield to call.

About the Bond Yield Calculator

The ByteTools Bond Yield Calculator works out what a bond actually returns at the price you can buy it for. Current yield is the easy part — annual coupon divided by market price — but yield to maturity has no closed-form solution, so the tool solves the discounted-cash-flow price equation numerically until the theoretical price matches the price you entered.

Enter a call price and a call date as well and you also get yield to call, which is the return if the issuer redeems the bond early. Comparing YTM against YTC is how investors judge callable bonds, because a bond bought at a premium can look attractive on maturity yield and much less so if it is called.

Coupon frequency, face value, price and dates are all yours to set — there is no bond database, no live pricing and no network access, and every calculation happens in your browser. The model uses whole coupon periods and ignores accrued interest and taxes, so it is a clean comparison tool rather than a settlement calculation.

Frequently asked questions

How do you calculate current yield on a bond?

Divide the annual coupon payment by the current market price. A bond with a $1,000 face value and a 6% coupon pays $60 a year, so at a market price of $950 the current yield is 60 ÷ 950 = 6.32%.

What is yield to maturity and why does it need solving?

YTM is the single discount rate that makes the present value of every remaining coupon plus the face value equal the market price. That equation cannot be rearranged for the rate, so it has to be solved numerically — this tool narrows the answer by bisection until it converges.

Why is my yield to maturity higher than the coupon rate?

Because you are buying below par. A discount bond returns the coupon plus the pull to par at maturity, so its YTM exceeds the coupon rate. A bond trading at a premium works the other way, and a bond priced exactly at par has a YTM equal to its coupon rate.

What is yield to call?

It is the yield you would earn if the issuer redeemed the bond at the first call date and call price rather than holding it to maturity. For premium bonds it is usually the lower of the two figures, which is why callable bonds are often judged on yield to worst.

Does this include accrued interest or tax?

No. It assumes you buy at the start of a coupon period, so there is no accrued interest to settle, and it reports pre-tax yields. Real settlement adds accrued interest to the invoice price and your own tax treatment changes the net return.
