What is the Bond Price Calculator?
Price a bond from its coupon, yield and years to maturity. To use the Bond Price Calculator, enter face value, coupon rate, market yield, years to maturity, payments per year; it returns bond price, premium or discount, annual coupon, and shows them instantly as you type.
Pricing bonds and testing credit
Price a bond with the Bond Price Calculator, solve for yield with the Bond YTM Calculator and measure rate risk with convexity and duration. If the bond is callable, compare yield to maturity with the yield to call.
On the credit side, combine Debt to Equity Calculator, interest coverage and the Altman Z-score. Together they show leverage, ability to pay and the odds of distress.
- Yields. Current yield, YTM, yield to call and bond-equivalent yield answer different questions.
- Coverage. DSCR, times interest earned and cash flow to debt show repayment capacity.
- Loss. LGD and credit spread translate risk into expected loss and extra yield.

Formula and how it works
Example with real numbers
Here is the Bond Price Calculator using the default values shown in the calculator above:
Inputs
| Face value ($) | 1,000 |
|---|---|
| Coupon rate (%) | 4.5 |
| Market yield (%) | 5.5 |
| Years to maturity | 10 |
| Payments per year | 2 |
Results
| Bond price | $923.86 |
|---|---|
| Premium or discount | -$76.14 |
| Annual coupon | $45.00 |
With these inputs the calculator returns Bond price: $923.86. Change any value in the calculator to see how the result moves.
What if you change one input?
Sensitivity check: raising Face value ($) from 1,000 to 1,200 (about 20% higher) and leaving everything else as in the example above changes the results like this:
| Result | Example | After the change | Change |
|---|---|---|---|
| Bond price | $923.86 | $1,108.64 | +20% |
| Premium or discount | -$76.14 | -$91.36 | -20% |
| Annual coupon | $45.00 | $54.00 | +20% |
The input that moves the result most is the one to check twice. Change it in the calculator above to test your own case.

Frequently asked questions
Why do bond prices fall when yields rise?
Existing coupons become less attractive, so the price drops until the yield matches the market.
What interest coverage is safe?
Above about 3 times is comfortable; below 1.5 times signals stress.
What do solvency ratios tell me?
Ratios such as debt to equity, interest coverage and the Altman Z-score show how safely a company can meet its debts.
Are the results guaranteed?
No. Results depend entirely on the numbers you enter and the formulas shown on this page. Please do not make financial decisions based on them alone; confirm important figures with a licensed professional.
