Yield is the annual rate of return on a security. For example, the yield is the annual percentage rate of return earned on a bond calculated by dividing the coupon interest rate by its purchase price.

Yield from Issue Date

With savings bonds, the Yield from Issue Date is a percentage expressed as an annual rate that describes the overall increase in an investment’s value and is a measurement of the gain from the time the investment was made or started. Such a percentage is the result of computations using the amount of the initial investment, what the investment is worth on some later date–today or in the future–and the amount of time from when the investment was made to the later date.
