Simple Definition

The fixed interest rate a bond pays, based on its face value.

Why It Matters

The coupon is the set interest a bond promises — a 4% coupon on a $1,000 bond pays $40 a year, usually in two installments. It never changes, which is why a bond's yield (the actual return based on its current price) can differ from its coupon once the bond trades on the market.

Key Points

  • Coupon rate is fixed at issue and stays the same for the life of the bond
  • Coupon is based on face value, not the price you pay
  • The name comes from old paper bonds with detachable interest coupons
