Coupon rate is the stated percentage rate of interest on a bond, which is usually paid out once a year or twice a year. For instance, a bond with a face value of ¥100 that pays interest twice a year of ¥5, would have a Coupon Rate of 10%.
Bond yield is the interest a bond will earn annually if it were purchased at its current price and held to maturity. For example, if a bond has a yield of 9.0%, the bond holder will have an annual rate of return of 9.0% on the amount of money invested.
