Understanding Series EE Bond Maturity and Interest Growth

Series EE bonds earn interest monthly and compound semiannually. The U.S. Treasury guarantees that the bond will double in value after 20 years. If left unredeemed, they can continue earning interest for up to 30 years.

Here’s a breakdown of Series EE bond growth over time:

Bond DenominationValue After 10 YearsValue After 20 YearsValue After 30 Years
$50~$66$100~$132
$100~$133$200~$265
$500~$666$1,000~$1,325
$1,000~$1,330$2,000~$2,650

These values assume the bonds remain untouched and continue to accrue interest under current Treasury rates.

When Should You Cash in EE Bonds?

The best time to cash in Series EE bonds depends on your financial goals:

  • If you need the money early, you can redeem them after 12 months, but you’ll lose the last three months’ interest if cashed before five years.
  • If you hold them for 20 years, the bond’s value doubles.
  • If you wait until 30 years, you’ll earn maximum interest before the bond stops accruing.

Series EE Bonds Maturity Formula

To manually calculate your bond’s value, you can use this formula:

FV = P × (1 + r/n)^(nt)

Where:

  • FV = Future Value of the bond
  • P = Original purchase price (e.g., $50 for a $100 bond)
  • r = Annual interest rate (varies based on the issue year)
  • n = Number of times interest compounds per year (usually 2)
  • t = Number of years held

For example, if you purchased a $100 EE bond in 2000 and want to calculate its value after 30 years at an estimated 3.5% interest rate:

FV = 50 × (1 + 0.035/2)^(2×30) = ~$265

Our Series EE Bonds Maturity Calculator simplifies this process by automatically applying the correct interest rates for each bond issue year.

Final Verdict

Series EE savings bonds are a great investment for long-term savings, especially with their guaranteed 2x value after 20 years. If you’re wondering how much a $100 savings bond is worth after 30 years, or when to cash in your EE bonds, our Series EE Bonds Maturity Calculator provides accurate estimates instantly.
