Difference Between Coupon and Yield
Coupon refers to the amount which is paid as the return on the investment to the holder of the bond by bond issuer which remains unaffected by the fluctuations in purchase price whereas, yield refers to the interest rate on bond that is calculated on basis of the coupon payment of the bond as well as it current market price assuming bond is held till maturity and thus changes with the change in the bond’s market price.
What is Coupon Rate?
Whenever a bondholder decides to put his money on a bond, he needs to look at certain parts that make up a bond. A bond has a face value, which is the amount the bondholder will receive at the time of maturity from the issuer of the bond. The coupon rate on the bond is calculated on the basis of the face value of the bond.
For example, suppose the face value of an XYZ bond is $1000, and the coupon payment for the bond is $20 semi-annually, then on an annual basis, the total coupon that will be received by the investor will be $40. The way the coupon rate is calculated is by dividing the annual coupon payment by the face value of the bond. In this case, the coupon rate for the bond will be $40/$1000, which is a 4% annual rate.
It can be paid quarterly, semi-annually, or yearly depending on the bond. Irrespective of the change in the price of a bond, the coupon rate will remain fixed for the life of the bond.
