Coupon tells us the rate of returns(%) for the bonds when it was first issued based on issue price. Yield tells us the rate of returns(%) for the bond based on current price. Assuming a bond was issued at $1000, promising to pay $50 yearly, it has a coupon rate of 5% & yield of 5%. However, if due to unforseen circumstances the bond price drops to $500, it still has a coupon rate of 5% but the yield is currently 10%. Coupon (%) = Returns / Issue Price * 100.
A bond's coupon rate is the actual amount of interest income earned on the bond each year based on its face value. A bond's yield to maturity is the estimated rate of return based on the assumption it is held until maturity date and not called. Yield to maturity includes the coupon rate within its calculation. Investors are more likely to make investing decisions based on an instrument's yield to maturity than its coupon rate.
