Free savings bond value calculator. Estimate the current value of Series EE and Series I savings bonds based on issue date, denomination, and applicable interest rates.
The Savings Bond Value Calculator estimates the current value of your Series EE or Series I savings bonds. Enter the bond series, issue date, denomination, and applicable interest rate to see the current value, total interest earned, and effective annual return.
Millions of savings bonds are held by American families, many inherited or received as gifts years ago. Determining their current value can be confusing because interest rules differ between Series EE and Series I, and rates have changed over the decades. This calculator provides a simplified estimate based on the key parameters.
For official valuations, always check the TreasuryDirect.gov savings bond calculator. This tool is designed for quick estimates and educational use. Many people have old Series EE or Series I savings bonds tucked away in drawers or safes without a clear idea of their current value. This calculator provides a fast estimate so you can decide whether to hold, redeem, or gift these bonds.
If you have old savings bonds in a drawer, you need to know their value for financial planning, tax preparation, or to decide whether to redeem them. This calculator gives you a quick estimate without needing to navigate the Treasury website, though you should verify exact values on TreasuryDirect for official purposes.
Series EE (post-2005): Value = Purchase Price × (1 + Fixed Rate / 2)^(Semesters Held) With 20-year guarantee: Value at month 240+ = min(2 × Face, Compound Value) Series I: Value = Purchase Price × (1 + Composite Rate / 2)^(Semesters Held) Composite Rate = Fixed Rate + 2 × Inflation Rate + Fixed × Inflation For bonds held < 5 years, subtract 3 months of interest as penalty.
Result: Estimated value: $111.06
A $100 Series EE bond issued in 2010 at a 1.4% fixed rate, held for 15 years (30 semesters): $50 purchase price × (1 + 0.014/2)^30 = $61.06 from compounding. Since it has not reached the 20-year doubling guarantee, the value is approximately $61.06. Note: EE bonds are purchased at half face value, so the $100 denomination bond cost $50.
Savings bond valuation depends on the series, issue date, and applicable interest rates. EE bonds issued after May 2005 earn a fixed rate set at purchase, while older EE bonds may earn variable rates that changed with market conditions. I bonds combine a fixed rate with a semi-annual inflation adjustment, making their value harder to predict long-term.
One of the most powerful features of Series EE bonds is the Treasury's guarantee that they will be worth at least double their purchase price at 20 years. If the fixed rate would not produce that doubling, Treasury makes a one-time adjustment. This effectively guarantees a minimum 3.5% annualized return over 20 years.
If you have inherited or accumulated multiple savings bonds, organize them by issue date and series. Identify any bonds that have stopped earning interest (past 30 years) for immediate redemption. For active bonds, compare their effective yield against current savings rates to decide whether to hold or redeem.
The most accurate way is to use the official TreasuryDirect.gov Savings Bond Calculator. You will need the series (EE or I), denomination, and issue date. For quick estimates, this calculator provides an approximation based on the bond's rate and time held.
Series EE bonds earn a fixed rate and are guaranteed to double in value at 20 years. Series I bonds earn a combination of a fixed rate and an inflation-adjusted rate that changes every 6 months, providing protection against inflation. Both have a 30-year maturity.
Series I bonds can be excellent during periods of high inflation, as their rate adjusts semi-annually. Series EE bonds are best for long-term holding (20+ years) due to the doubling guarantee. Both offer tax advantages and are backed by the U.S. government, making them essentially risk-free.
Cash in bonds that have stopped earning interest (after 30 years). For EE bonds under 20 years old, consider waiting for the doubling guarantee. For I bonds, hold as long as the composite rate remains competitive. Always wait at least 5 years to avoid the 3-month interest penalty.
Yes, savings bond interest is subject to federal income tax but exempt from state and local taxes. You can defer the tax until you redeem the bond or report it annually. If used for qualified education expenses, the interest may be tax-free under certain income limits.
Paper savings bonds are no longer sold. Since January 2012, all savings bonds are issued electronically through TreasuryDirect.gov. The only exception is paper Series I bonds, which can be purchased with your federal tax refund using IRS Form 8888.
