Coupon Rate Calculator
Calculate a bond’s coupon rate from its face value and coupon payment (annual, semi-annual, quarterly or monthly), plus annual coupon income and the current yield at the market price.
How it works
Annual coupon = coupon payment × payments per year · coupon rate = annual coupon ÷ face value × 100 · current yield = annual coupon ÷ market price × 100
The coupon rate is the fixed interest a bond pays each year as a percentage of its face (par) value, set when the bond is issued. It does not change when the bond’s market price moves — that change shows up in the current yield and the yield to maturity instead. A bond that pays 25 twice a year on 1,000 of face value has a 5% coupon whether it trades at 980 or 1,050.
Worked example
A bond with a face value of 1,000 paying 25 every six months pays 25 × 2 = 50 a year, so its coupon rate is 50 ÷ 1,000 = 5.000%. Bought at 980, a discount, its current yield is 50 ÷ 980 = 5.102%.

Frequently asked questions
Is the coupon rate the same as the yield?
No. The coupon rate is fixed on face value. Current yield and yield to maturity use the price you pay, so they rise when the price falls below par and fall when it rises above par.
How do you calculate a semi-annual coupon payment?
Multiply the face value by the coupon rate and divide by 2. A 1,000 bond with a 6% coupon pays 60 a year, or 30 every six months.
Why do bonds with different coupons trade at different prices?
Investors want a market yield. A bond whose coupon is above current rates trades at a premium and one below current rates trades at a discount until its yield matches the market.
What is a zero-coupon bond’s coupon rate?
Zero. It pays no periodic interest; the return comes from buying it below face value and receiving the full face value at maturity.
