Bond Return Comparison

Bond yield calculator guide: current yield, yield to maturity, coupon income, and pull-to-par

A bond yield calculator compares the income yield you can see today with the total annualized return implied if the bond is held to maturity. That distinction matters because coupon income alone can understate or overstate the real return when the bond is trading at a discount or a premium to face value.

What bond yield is measuring

Current yield is the simplest measure: annual coupon income divided by the bond's current market price. It is useful for a quick income snapshot, but it ignores how far the price is from face value and therefore ignores the gain or loss that can occur if the bond is held to maturity.

Yield to maturity is broader. It asks what annualized discount rate makes the bond's remaining coupon payments plus its redemption value equal to today's price. That is why two bonds with the same coupon can have different yields when they trade at different prices.

Why current yield and yield to maturity can differ

A discount bond often has a yield to maturity above its current yield because the investor may receive both coupon income and a gain as the price pulls back toward face value by maturity. A premium bond can show the opposite pattern because part of the purchase premium may be lost over time.

That is why coupon rate, current yield, and yield to maturity should not be treated as interchangeable. Coupon rate describes the bond contract. Current yield describes income on today's price. Yield to maturity tries to summarize the full hold-to-maturity return under simplified assumptions.

Current yield = Annual coupon income / Current market price

The income-only yield measure that ignores price convergence toward face value.

Bond price = Present value of coupon cash flows + Present value of face value

The bond-pricing identity used to solve yield to maturity by iteration.

Worked example: 95 price, 100 face value, 5.00% coupon, 5 years remaining

Suppose a bond trades at 95.00, has a 100.00 face value, pays a 5.00% annual coupon, and matures in five years. Current yield is about 5.26%, because the annual coupon income of 5.00 is divided by the lower market price of 95.00.

Yield to maturity is higher, about 6.19%, because the investor is also projected to recover the 5.00 discount back to face value by maturity. The gap between those two measures is the price effect that current yield leaves out.

What this calculator leaves out

This version is built for transparent education and quick comparison. It does not model accrued-interest settlement, taxes, default risk, call features, odd coupon schedules, or changes in reinvestment rates for coupon cash flows.

Those details matter in real bond analysis. For plain-vanilla screening, though, current yield and yield to maturity are still a useful first pass when the bond's cash-flow pattern is standard and the investor understands the simplifying assumptions.

Frequently asked questions

Why is yield to maturity higher than current yield on a discount bond?

Because yield to maturity includes both coupon income and the gain from the bond price rising back toward face value by maturity, while current yield looks only at coupon income divided by today's price.

 Does this calculator assume I can reinvest coupons at the same rate?

The standard yield-to-maturity concept assumes interim cash flows can be reinvested, but this calculator does not model a separate reinvestment path or changing reinvestment rates over time.

 Should I use this for callable or distressed bonds?

Not by itself. Callable, defaultable, or otherwise non-standard bonds often need yield-to-call, yield-to-worst, spread analysis, and deeper credit review beyond a plain hold-to-maturity estimate.

 Is coupon rate the same as bond yield?

No. Coupon rate is fixed by the bond contract, while bond yield depends on the current market price and, for yield to maturity, the relationship between that price and the redemption value.
