Current yield is the income from an investment expressed as a percentage of its price. For example, the current yield of a bond fluctuates with a bond's price on the secondary market. To find the current yield, you divide the coupon by the bond's current market price. So a bond with a $1,000 face value and a coupon of 6% purchased at $900 has a current yield of 6.7% (60/900). When the bond's price rises its current yield falls and when it falls its current yield rises.
