A bond yield calculator helps you evaluate fixed-income investments by computing current yield, yield to maturity (YTM), and fair bond prices. Whether you are comparing corporate bonds, treasury securities, or municipal bonds, understanding yield metrics is essential for making informed investment decisions. Use this free tool to analyze individual bonds or compare two bonds side by side.

How to Use This Bond Yield Calculator
Evaluating bonds requires understanding multiple yield metrics. Current yield tells you the income return, but yield to maturity (YTM) gives the full picture by accounting for capital gains or losses when the bond matures at face value. This bond yield calculator handles all the complex math so you can focus on making smart fixed-income investment decisions.
Step 1: Choose Your Calculation Mode
Select one of three modes at the top of the calculator. Find Yields calculates the current yield and YTM when you know the bond's market price. Find Price determines the fair price to pay for a bond given your target YTM. Compare lets you evaluate two bonds side by side to see which offers better value.
Step 2: Enter Bond Details
Enter the face value (usually $1,000 for corporate and treasury bonds), the coupon rate (the annual interest rate printed on the bond), the current market price (what you would pay today), years until the bond matures, and the payment frequency. Most US bonds pay semi-annually, while many international bonds pay annually.
Step 3: Understand Your Results
The calculator displays current yield (annual coupon divided by price), yield to maturity (total annualized return including price appreciation), premium or discount status, total coupon payments over the bond's life, and total return if held to maturity. A price sensitivity note explains how interest rate changes may affect the bond's market value based on its duration.
Step 4: Use Find Price for Target Returns
If you have a target yield in mind, switch to Find Price mode. Enter the bond's face value, coupon rate, your desired YTM, and years to maturity. The calculator determines the maximum price you should pay to achieve that return. This is especially useful when evaluating bonds in the secondary market or setting limit orders.
Step 5: Compare Bonds for Best Value
Use the Compare mode when deciding between two bond investments. The side-by-side comparison shows current yield, YTM, total return, and premium/discount status for each bond. Focus on YTM as the primary comparison metric since it represents the total annualized return accounting for both income and capital gains. All calculations run privately in your browser with no data stored or shared.
FAQ
Is this bond yield calculator free?
Yes, this bond yield calculator is completely free with no hidden fees, no signup, and no limits. You can calculate current yield, yield to maturity, and bond prices as many times as you need. Everything runs in your browser.
Is my financial data safe?
Absolutely. All calculations run entirely in your browser using client-side JavaScript. Your bond data is never sent to any server or stored in any database. You can verify this by disconnecting from the internet — the calculator continues to work perfectly.
What is the difference between current yield and yield to maturity?
Current yield is simply the annual coupon payment divided by the current market price, expressed as a percentage. Yield to maturity (YTM) is a more comprehensive measure that accounts for coupon payments, the difference between purchase price and face value, and the time remaining until maturity. YTM represents the total annualized return if you hold the bond until it matures.
What does it mean when a bond trades at a premium or discount?
A bond trades at a premium when its market price is above its face value (par), usually because its coupon rate is higher than current market rates. A bond trades at a discount when its price is below face value, typically because its coupon rate is lower than prevailing rates. At maturity, all bonds return to face value regardless of the purchase price.
How is yield to maturity (YTM) calculated?
YTM is calculated by finding the discount rate that makes the present value of all future cash flows (coupon payments plus face value at maturity) equal to the current market price. This requires iterative numerical methods like Newton's method since there is no closed-form solution. This calculator uses Newton's method for precise YTM results.
Does payment frequency affect bond yield?
Yes, payment frequency affects the effective yield. Semi-annual bonds, which are the most common in the US, pay interest twice per year. This means you receive cash flows sooner and can reinvest them, resulting in a slightly higher effective annual yield compared to an annual-pay bond with the same stated coupon rate.
How do I compare two different bonds?
Use the Compare mode in this calculator to enter details for two bonds side by side. The tool will calculate current yield, YTM, and total return for each bond, making it easy to see which offers better value. Focus on YTM rather than current yield for the most accurate comparison of total expected return.
