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

Bond yield measures the return on a bond investment.

Current yield focuses on annual interest payments, while yield to maturity considers total return.

Bond prices and yields move in opposite directions.
