How the Bond Yield to Maturity Calculator Works
Yield to maturity (YTM) is the most complete measure of a bond’s return, accounting for coupon payments, the purchase price, and the face value received at maturity.
This bond YTM calculator computes:
- Annual Coupon Payment — the dollar amount paid each year
- Approximate Yield to Maturity — a quick estimate
- Precise Yield to Maturity — solved iteratively for accuracy
- Current Yield — annual coupon income relative to price
- Total Return if Held to Maturity — overall gain including price appreciation
Bond YTM Formula
Approximate YTM
YTM ≈ [C + (F − P) ÷ n] ÷ [(F + P) ÷ 2]
Where: - C = Annual coupon payment - F = Face value - P = Current price - n = Years to maturity
The precise YTM is found by solving for the rate y such that the present value of all coupon payments plus the face value equals the current price.
Bond YTM Examples
Example 1: Discount Bond
| Variable | Value |
|---|---|
| Face Value | $1,000 |
| Current Price | $950 |
| Coupon Rate | 5% |
| Years to Maturity | 10 |
| Approximate YTM | 5.54% |
Example 2: Premium Bond
| Variable | Value |
|---|---|
| Face Value | $1,000 |
| Current Price | $1,080 |
| Coupon Rate | 6% |
| Years to Maturity | 5 |
| Approximate YTM | 4.32% |

Frequently Asked Questions
What is yield to maturity (YTM)?
Yield to maturity is the total annualized return an investor can expect if a bond is held until it matures, accounting for coupon payments, purchase price, and face value.
How is YTM calculated?
YTM can be approximated using a simplified formula, or calculated precisely by finding the discount rate that makes the present value of all future coupon payments and the face value equal to the bond’s current price.
What’s the difference between current yield and YTM?
Current yield only considers annual coupon income relative to price, while YTM also factors in any gain or loss from the difference between the purchase price and face value at maturity.
Why would a bond trade below face value?
A bond trades below face value (at a discount) when its coupon rate is lower than prevailing market interest rates, making it less attractive unless priced lower to compensate investors.
