What is a savings bonds maturity chart?

A savings bond maturity chart shows the value of a savings bond based on its stated maturity and current age, and is available on Treasury Direct, the U.S. Department of the Treasury website. This chart is used to calculate the interest that accumulates on a given savings bond.

The savings bond maturity chart allows a bond owner to look up the year the savings bond was issued and determine how much interest has accrued based on the interest rate and year, according to Treasury Direct. The maturity chart shows the approximate value if the bond is redeemed immediately, compared to the value if it is redeemed at maturity.
