Frequently Asked Questions

Q

How do you calculate bond yield?

Current Yield = (Annual Interest Payment / Purchase Price) × 100%. Yield to Maturity considers both interest payments and the difference between purchase price and face value at maturity.

  • Current yield: $500 annual interest / $9,500 purchase price = 5.26%
  • YTM adds capital gain/loss: ($500 + ($10,000 – $9,500)/10) / $9,500 = 5.79%
  • Coupon rate is fixed at issuance; yield changes as market price fluctuates
  • When bond prices drop 10%, yields rise proportionally – they move inversely
Q

What is the difference between current yield and yield to maturity?

Current yield only considers annual interest payments relative to purchase price. Yield to Maturity (YTM) accounts for both interest payments and capital gains/losses if held to maturity, providing a more complete picture.

  • Current yield ignores the $500 gain when a $9,500 bond matures at $10,000
  • YTM spreads capital gain/loss evenly across remaining years to maturity
  • For bonds at par value (price = face), current yield and YTM are equal
  • Discount bonds: YTM > current yield (you gain at maturity)
  • Premium bonds: YTM < current yield (you lose at maturity)

Q

What is a good bond yield?

Bond yields vary by type and risk. Treasury bonds: 3-5%, Corporate bonds: 4-7%, High-yield bonds: 6-10%. Higher yields typically indicate higher risk. Compare yields to inflation and other investment options.

  • 10-Year US Treasury: 4.0–4.5% (2024–2025) – the risk-free benchmark
  • Investment-grade corporate (AAA–BBB): 4.5–6.5% – low default risk
  • High-yield / junk bonds (BB and below): 6.5–10%+ – higher default risk
  • Municipal bonds: 3–5% but tax-exempt – effective yield is higher for high earners
  • Subtract inflation (currently ~3%) to find real yield – e.g., 5% nominal = 2% real
Bond TypeTypical YieldRisk Level
US Treasury3.5–4.5%Very low (government-backed)
Investment Grade Corporate4.5–6.5%Low to moderate
High-Yield Corporate6.5–10%+Moderate to high
Municipal3–5% (tax-free)Low
Q

Should I buy bonds at a discount or premium?

Bonds purchased below face value (discount) offer higher yields and potential capital gains at maturity. Bonds purchased above face value (premium) offer lower yields but may have higher coupon rates. Consider your investment goals and risk tolerance.

  • Discount bond: buy $1,000 face value bond for $950 – earn $50 capital gain at maturity
  • Premium bond: buy $1,000 face value bond for $1,050 – lose $50 at maturity but receive higher coupon
  • Zero-coupon bonds sell at deep discounts (e.g., $600) and pay $1,000 at maturity – no interest payments
  • Tax note: capital gains on discount bonds may be taxed as ordinary income if purchased at original issue
  • In a rising rate environment, existing bonds trade at discounts – opportunity for higher YTM

Example Calculations

1$10,000 Bond Purchased at $9,500 with 5% Coupon

Inputs

Face Value$10,000
Purchase Price$9,500
Coupon Rate5%
Years to Maturity10

Result

Current Yield5.26%
Yield to Maturity5.79%
Annual Interest$500
Total Interest$5,000
Total Return$5,500

A $10,000 face value bond with a 5% coupon pays $500/year in interest. Purchased at a discount for $9,500, the current yield is $500/$9,500 = 5.26%. The yield to maturity is higher at 5.79% because you also gain $500 ($10,000 - $9,500) when the bond matures, adding $50/year to average returns.

2$5,000 Bond Purchased at $4,800 with 4% Coupon

Inputs

Face Value$5,000
Purchase Price$4,800
Coupon Rate4%
Years to Maturity5

Result

Current Yield4.17%
Yield to Maturity5.00%
Annual Interest$200
Total Interest$1,000
Total Return$1,200

This $5,000 bond with a 4% coupon pays $200/year. Bought at $4,800, the current yield is $200/$4,800 = 4.17%. The YTM is 5.00% because you also receive $200 capital gain at maturity ($40/year average), for a total return of $1,200 over the 5-year term.

Formulas Used

Current Yield

Current Yield = (Annual Interest / Purchase Price) x 100

Measures the annual income return based on the price paid for the bond.

Where:

Annual Interest= Face Value x (Coupon Rate / 100)
Purchase Price= The price paid to buy the bond

Yield to Maturity (Simplified)

YTM = ((Annual Interest + (Face Value - Purchase Price) / Years) / Purchase Price) x 100

An approximation of the total annual return if the bond is held to maturity, including both coupon payments and capital gain or loss.

Where:

YTM= Yield to maturity percentage
Annual Interest= Yearly coupon payment (Face Value x Coupon Rate)
Face Value= Par value of the bond (received at maturity)
Purchase Price= Price paid for the bond
Years= Years until maturity

Understanding Bond Yields and Fixed-Income Returns

How Bond Yields Work: Current Yield vs Yield to Maturity

A $10,000 face value bond with a 5% coupon rate pays $500 in annual interest regardless of the market price. If purchased at par ($10,000), the current yield equals the coupon rate at 5.00%. But bonds rarely trade at par — when purchased at a $9,500 discount, the current yield rises to $500 / $9,500 = 5.26% because you pay less for the same $500 income stream.

Yield to maturity (YTM) captures the complete return picture by adding the capital gain or loss at maturity. That $9,500 purchase price on a $10,000 face value bond adds $500 in capital gain spread over the remaining term. With 10 years to maturity, the $50/year capital gain pushes the YTM to approximately 5.79% — 53 basis points above the current yield. Conversely, a bond purchased at a $10,500 premium loses $500 at maturity, lowering YTM below the current yield.

The relationship between price and yield is inverse: when bond prices fall 10%, yields rise proportionally. This mechanism explains why rising interest rates cause existing bond prices to drop — new issues offer higher coupons, making older bonds less attractive until their price adjusts to deliver a competitive yield.

Bond Yield Benchmarks by Type and Risk

The 10-Year U.S. Treasury yielded 4.0–4.5% through 2024–2025, serving as the baseline risk-free rate against which all other bonds are measured. Investment-grade corporate bonds (rated AAA through BBB) typically pay 50–200 basis points above Treasuries, translating to 4.5–6.5% yields. High-yield or “junk” bonds (rated BB and below) compensate for higher default risk with yields of 6.5–10% or more.

Municipal bonds offer yields of 3–5% but carry a significant hidden advantage: interest is exempt from federal income tax and often state tax as well. A 4% municipal bond provides an effective yield of 5.6% for an investor in the 28% federal bracket (4% / (1 – 0.28) = 5.56%). This makes munis particularly attractive for high-income earners seeking tax-efficient fixed income.

Real yield — nominal yield minus inflation — is what actually grows your purchasing power. With inflation averaging approximately 3% in 2024–2025, a 5% Treasury bond delivers only 2% real return. Treasury Inflation-Protected Securities (TIPS) guarantee a real yield above CPI, making them a hedge against unexpected inflation spikes.

Premium vs Discount Bonds: Which to Buy

Discount bonds trade below face value, offering both coupon income and a capital gain at maturity. A $10,000 bond purchased at $9,200 with an 8-year maturity delivers a $100/year capital gain ($800 / 8) on top of the coupon. For a 5% coupon bond, that transforms a 5.43% current yield into approximately 6.52% YTM — a meaningful difference for income-focused investors.

Premium bonds carry above-market coupon rates but lose value at maturity. Buying a $10,000 bond at $10,800 with a 6% coupon means you collect $600/year in interest but lose $800 at maturity over, say, 10 years ($80/year capital loss). The current yield of 5.56% ($600 / $10,800) drops to a YTM near 4.80% once the capital loss is factored in.

Zero-coupon bonds represent the most extreme discount: they pay no periodic interest and sell at deep discounts. A 10-year zero-coupon bond with $10,000 face value might sell for $6,139, delivering a 5.00% YTM entirely from capital appreciation. These are ideal for specific future obligations like college tuition because the final payout is known with certainty.

Tip: In a rising rate environment, existing bonds trade at discounts. This creates buying opportunities for investors willing to hold to maturity, locking in higher YTMs than new-issue coupon rates suggest.

How to Use This Bond Yield Calculator

Enter four inputs to calculate both current yield and yield to maturity: face value (the par amount you receive at maturity), purchase price (what you actually paid), annual coupon rate (the stated interest rate), and years to maturity (remaining time until the bond matures). The calculator displays current yield, YTM, annual interest, total interest, and total return immediately.

Compare multiple bonds by running separate calculations. A $10,000 Treasury at $9,800 with a 4.25% coupon and 7 years to maturity produces a different risk-adjusted return than a $10,000 corporate bond at $9,500 with a 5.5% coupon and 10 years. Side-by-side comparison helps determine which bond offers better value for your risk tolerance and investment horizon.

  1. 1

    Enter face value

    Most bonds have a $1,000 or $10,000 face value. This is the amount the issuer pays you at maturity.

  2. 2

    Enter purchase price

    The actual amount you paid or plan to pay. Below face value = discount bond; above = premium bond.

  3. 3

    Set coupon rate

    The annual interest rate printed on the bond. A 5% coupon on $10,000 face value pays $500/year.

  4. 4

    Set years to maturity

    Remaining years until the bond matures and you receive the face value. Longer maturities amplify the YTM/current yield gap.

  5. 5

    Compare current yield and YTM

    YTM is the more complete measure. Use it to compare bonds with different prices, coupons, and maturities on an equal basis.
