How does this calculator work?
Coupon Rate = (Annual Coupon ÷ Face Value) × 100%. Current Yield = (Annual Coupon ÷ Market Price) × 100%. A $1,000 bond paying $50/year has a 5% coupon rate; if it trades at $950, its current yield is 5.26%. Coupon rate is fixed; current yield moves with price.
Formula
How this is calculated
The coupon rate is set at issuance and remains fixed for the life of the bond. It expresses the annual interest payment as a percentage of the par (face) value. A $1,000 bond paying $50 per year has a coupon rate of 5%. This rate does not change, regardless of what happens to market interest rates or the bond price.
The current yield differs from the coupon rate whenever the bond trades above or below par. If market rates rise after issuance, the bond falls in price (discount) and the current yield rises above the coupon rate — buyers are getting the same $50 payment for less money. Conversely, if the bond trades at a premium, the current yield falls below the coupon rate. The premium/discount row shows how far the market price deviates from par.
Note: current yield is simpler than yield to maturity (YTM). YTM also accounts for the capital gain or loss when the bond is redeemed at par at maturity. Use a YTM calculator for a full picture of total return.
Frequently asked questions
Coupon rate is fixed at issuance — it is the annual payment as a % of face value. Current yield = annual coupon ÷ market price, which changes as the price moves. Yield to maturity (YTM) goes further and factors in the gain/loss from buying at a premium or discount.
Yes — zero-coupon bonds pay no periodic interest. They are issued at a deep discount and redeemed at par. Enter 0 for the annual coupon to see a coupon rate of 0%.
A bond trades at a premium when its market price is above face value (par). This usually happens when market interest rates have fallen since issuance, making the bond's higher coupon attractive. The current yield will then be lower than the coupon rate.
