Each savings bond is issued to an individual owner with a serial number to track the ownership and value. Fortunately, you do not need the serial number to determine the value of any savings bond. All savings bonds issued by the Treasury in a month will earn the same interest rate and all bonds of the same denomination from that month will have the same value.
1. Collect the information you know about the savings bond for which you want the value. For an accurate value you need the type of savings bond -- series E, EE or I, the issue month and the denomination.
2. Locate the savings bond calculator on the TreasuryDirect.gov website. Find the calculator under the "Tools" tab on the "Individuals" side of the website. On the Savings Bond Calculator page, click the "Get Started" link to go to the actual calculator.
3. Enter the series, denomination value and issue month into the calculator and select "Calculate." The screen will refresh to show the current value of the savings bond plus the original cost and interest earned. For example, a $100 denomination series I bond issued in July 1999 was worth $201.52 at the time of publication, 12 years after issue. No serial number required.
- Enter the issue date using the month and year as in 07/1999 for July 1999.
- You can calculate the value of several bonds, one after the other, and the results for all the bonds will remain listed on the screen. If you are not sure of the bond issue date, use this feature to calculate the savings bond value over a range of months.
- Series E and EE bonds are sold for one-half of the denomination value. For example, a $500 series EE bonds costs $250 and will grow in value from the initial cost. Unless the bond is close to 20 years old, the calculated value of an EE bond will be less than the denomination value.
