(e.g., 0.10 for recent bonds. This rate applies for growth beyond 20 years, or for early redemption.)

Calculation Results:

Bond Face Value: $0.00

Years Held: 0 years

Current Estimated Value: $0.00

Total Interest Earned (Current): $0.00

Guaranteed Value at 20 Years: $0.00

Total Interest Earned (at 20 Years): $0.00

Note: This calculator provides an estimate based on the doubling guarantee and stated rates. For exact values, consult TreasuryDirect.gov.

Understanding Series EE Savings Bonds

Series EE Savings Bonds are a popular, low-risk savings product offered by the U.S. Department of the Treasury. They are known for their safety, tax advantages, and a unique feature that guarantees their value will at least double if held for 20 years.

How Series EE Bonds Work

  • Purchase Price: Unlike most bonds, Series EE bonds are purchased at half their face value. For example, a $100 bond costs $50. The minimum purchase is $25 (for a $50 face value bond).
  • Fixed Interest Rate: Bonds issued today earn a fixed interest rate for the first 20 years. This rate is typically very low (e.g., 0.10%). However, this stated rate isn't the full story.
  • Doubling Guarantee: The key feature for bonds issued May 2005 and later is a guarantee: if you hold the bond for 20 years, its value will at least double. If the stated fixed rate doesn't achieve this doubling, the Treasury makes a one-time adjustment at the 20-year mark to bring its value up to twice the purchase price. This means the effective yield to 20 years is approximately 3.53% compounded semi-annually.
  • Extended Earnings: After 20 years, the bond continues to earn interest at its stated fixed rate for an additional 10 years, for a total maturity period of 30 years.
  • Redemption: You can redeem EE bonds after one year, but you forfeit the last three months of interest if redeemed before five years.
  • Tax Advantages: Interest earned on EE bonds is exempt from state and local income taxes. Federal income tax can be deferred until you redeem the bond or it stops earning interest. Furthermore, if you use the proceeds to pay for qualified higher education expenses, the interest may be entirely tax-free at the federal level.

Using the Series EE Savings Bond Value Calculator

Our calculator helps you estimate the current and future value of your Series EE bonds. Here's how to use it:

  1. Bond Purchase Price ($): Enter the amount you paid for the bond. Remember, this is half of its face value (e.g., $50 for a $100 bond).
  2. Bond Issue Year: Input the year your bond was issued. This is crucial for determining how long it has been held.
  3. Current Year: Enter the current year to calculate the bond's age.
  4. Stated Fixed Rate (Annual %): Enter the fixed interest rate stated on your bond. For bonds issued recently, this might be a very low percentage (e.g., 0.10%). This rate is primarily used by the calculator for growth beyond the 20-year doubling period.

Click "Calculate Bond Value" to see:

  • The bond's full face value (double its purchase price).
  • How many years the bond has been held.
  • Its estimated current value and the interest earned to date.
  • Its guaranteed value at the 20-year mark and the total interest earned by then.

Example Calculation:

Let's say you purchased a Series EE bond for $50 in 2010, and the stated fixed rate was 0.10%. You want to know its value in 2023.

  • Bond Purchase Price: $50
  • Bond Issue Year: 2010
  • Current Year: 2023
  • Stated Fixed Rate: 0.10%

The calculator would show:

  • Bond Face Value: $100.00
  • Years Held: 13 years
  • Current Estimated Value: Approximately $78.54 (based on the effective rate to double in 20 years)
  • Total Interest Earned (Current): Approximately $28.54
  • Guaranteed Value at 20 Years: $100.00
  • Total Interest Earned (at 20 Years): $50.00

If you held this bond until 2030 (20 years), it would be worth $100. If you held it until 2035 (25 years), it would be worth approximately $100.50, as it would earn the 0.10% stated rate on the $100 face value for the additional 5 years.

Important Considerations:

While this calculator provides a good estimate, the exact value of your Series EE bond can be complex due to semi-annual compounding and specific Treasury rules. For the most precise and up-to-date valuation, especially for older bonds or those with specific issue dates, always refer to the official TreasuryDirect Bond Value Calculator.
