The Series EE Bond Value Calculator is a specialize tool designed to assist bondholders in determining the current value of their U.S. Series EE savings bonds. This calculator is essential for individuals planning their finances, as it accurately calculates the worth of these bonds based on factors such as age, denomination, and the interest rates that have been applied over time.
Formula of Series EE Bond Value Calculator
Calculating the current value of a Series EE savings bond involves several steps that consider the bond's details and the historical interest rates:
- Identify the Bond Details:
- Issue date of the bond.
- Denomination or face value of the bond.
- Purchase price, which is typically half of the face value for bonds issue before May 2005.
- Determine the Interest Rates:
- For bonds issued after May 2005: Fixed interest rates apply.
- For bonds issued before May 2005: Variable interest rates apply, obtainable from historical interest rate tables provided by the U.S. Treasury.
- Calculate the Accrued Interest:
- For pre-May 2005 bonds, calculate the semi-annual interest based on the variable rate.
- For post-May 2005 bonds, use the fix rate for the entire period the bond has been held.
- Compound the Interest:
- Interest on Series EE bonds is compound semi-annually.
- The formula used is: Future Value = Principal * (1 + (r / n))^(nt)
- Where:
- Principal is the purchase price of the bond.
- r is the annual interest rate (express as a decimal).
- n is the number of times interest compounds per year (2 for semi-annual).
- t is the total number of years the bond has been held.
- Add the Principal to the Accrued Interest:
- This sum gives the total current value of the bond.

Example of Series EE Bond Value Calculator
Consider a Series EE bond purchased in June 2003 with a face value of $100 and a purchase price of $50:
- Issue Date: June 2003
- Denomination: $100
- Purchase Price: $50
- Interest Rate: Variable, based on historical rates
- Calculation: Assume an average rate of 3% compounded semi-annually for 18 years.
Using the formula:
- Future Value = $50 * (1 + (0.03 / 2))^(2*18) = $50 * (1.015)^36 ≈ $91.44
Adding the principal:
- Total Value = $91.44 (This is an estimated current value based on assumed interest rates).
