U.S. savings bonds, like other Treasury securities, are considered safe investments because they are backed by the full faith and credit of the federal government. If you have invested in savings bonds for the long term or have given them to a child, you may want to check the interest rate before the bonds mature. A number of resources are available for this.
Visit the Savings Bond Calculator at the TreasuryDirect website to view the interest rate each of your bonds is earning. Type in the bond type, denomination, serial number and issue date. This information is available on the face of paper bonds or on your account page for electronic bonds purchased using TreasuryDirect. In the date drop-down box, choose the current month or a different month as the calculation date. Click the "Calculate" button. You will also see the total value, year-to-date interest and total interest figures.
Check the Treasury Department website Resource Center for the interest rates of series E and EE bonds. Click "FAQ," "Markets" and "Savings Bond Value & Redemption." The information is updated each May and November. The interest rates for these bonds vary by issue date.
Look at the redemption tables on TreasuryDirect to find the value and interest earned on series E, EE and I bonds. This online archive extends back to March 1999. The Bureau of the Public Debt also publishes these tables in pamphlet form each May and November.
