Term coupon rate Definition: The annual rate of return on a legal claim or financial asset (usually a bond) stated as a percent of par value. If, for example, a $100,000 corporate bond has a fixed payment of $5000 a year, then the coupon rate is 5%. The coupon rate is not necessarily, and generally is not, the same as the current yield or yield to maturity of a financial asset.
