Savings bonds issued by the U.S. Treasury have long been considered stable investments, accruing value up to twice the face denomination over a 20- to 30-year period. Bonds are issued in several series categories: EE/E, I, and Savings Notes. Traditionally, investors and consumers could buy paper bonds through banks and other financial institutions, but the Treasury Department has transitioned its bond operations to online management. The Treasury’s online savings bond calculator is the fastest and easiest way to check the accrued value of your bonds.
