Series EE bonds earn interest for 30 years from the issue date

A Series EE bond stops accruing interest exactly 30 years after you buy it. The U.S. Treasury issues these bonds with a fixed maturity period, and once that 30-year window closes, no new interest accumulates, even if you hold the bond longer.

The interest compounds semiannually — meaning the Treasury adds earned interest to your bond's value twice per year — throughout those three decades. This compounding effect is why Series EE bonds can roughly double in value if held to maturity, though the actual growth depends on the interest rate in effect when you purchased the bond.

You can cash in a Series EE bond anytime after you own it for one year. If you cash it in before five years have passed, you lose the last three months of interest as a penalty. After five years, you can redeem it without penalty, but it will continue earning interest until the full 30 years are up.

Key Takeaways

  • Series EE bonds earn interest for exactly 30 years from the purchase date, after which interest stops accruing.
  • Interest compounds every six months, so your bond's value grows twice per year throughout the 30-year period.
  • You can redeem a Series EE bond after one year, but redeeming before five years means losing three months of interest.
  • If you hold the bond past 30 years without redeeming it, the principal and all accrued interest remain in the bond but earn nothing new.

What happens to your bond after the 30-year maturity date

Once a Series EE bond reaches its 30-year maturity date, it stops earning interest permanently. The bond itself does not expire or disappear — you still own it and can hold it indefinitely — but your money stops growing. The final value is locked in on that 30-year anniversary.

You can redeem the bond at any point after maturity and receive the full value it reached at year 30. There is no penalty for holding it past maturity, but there is also no benefit. The Treasury will not force you to cash it in, so some people keep mature bonds in a safe deposit box or with their other documents, though this is purely a matter of preference.

Interest rates and how they affect your 30-year earnings

The interest rate on a Series EE bond is set by the Treasury and changes every six months. Bonds purchased in different months or years will have different rates, and those rates are locked in for the life of the bond. A bond you bought in 2015 earns a different rate than one you bought in 2024, and each rate stays the same for the full 30 years.

The Treasury announces new rates on May 1 and November 1 each year. You can find the current rate and historical rates on the TreasuryDirect website. Because rates are locked in at purchase, the total interest you earn over 30 years depends entirely on when you bought the bond, not on what rates do after you own it.

Series EE bonds are may provide to double in value if held for 20 years, regardless of the interest rate. This means if you bought a $100 bond, it will be worth at least $200 after 20 years. If the interest rate is high enough, it may reach that value sooner, but the 20-year doubling may provide is a floor, not a ceiling.

Cashing in before 30 years: penalties and timing

You can redeem a Series EE bond as early as one year after purchase, but the timing matters for your earnings. If you cash it in during years one through four, you forfeit the last three months of interest. This penalty applies regardless of when you redeem — whether it is at year 1.5 or year 4.9, you lose the same three months of accrued interest.

Starting in year five, you can redeem without any interest penalty. The bond will have earned interest for the full time you held it, and you receive all of it. Many people wait until at least year five for this reason, even if they need the money sooner, because the penalty can be substantial depending on the interest rate.

If you redeem before 30 years, the remaining time does not matter — you do not earn interest for the years you did not hold the bond. A bond redeemed at year 10 earns interest only for those 10 years, not for the full 30-year potential.

Comparing Series EE bonds to other savings bonds

Series I bonds also earn interest for 30 years and have the same one-year holding requirement and five-year penalty structure. The key difference is that I bonds have a variable interest rate that adjusts every six months based on inflation, while EE bonds have a fixed rate set at purchase. If you expect inflation to rise, I bonds may grow faster; if you want predictability, EE bonds lock in your rate.

Series HH bonds (no longer sold but still held by many people) also mature at 30 years but pay interest differently — they send you a check twice per year instead of compounding the interest into the bond's value. This makes them useful for people who want regular income rather than growth.

Treasury notes and bonds sold through TreasuryDirect have different maturity periods — notes mature in 2, 3, 5, or 10 years, and bonds mature in 20 or 30 years. Unlike savings bonds, they are not redeemable early without selling them on the secondary market, which may result in a loss if interest rates have risen.

Tracking your bond's value over time

You can check the current value of your Series EE bonds anytime through your TreasuryDirect account online. The site shows the issue date, current value, and the interest rate your bond earns. If you own paper bonds, you can use the Savings Bond Calculator on the Treasury website — you enter the series, denomination, and issue date, and it calculates the current value based on the rate for that bond.

The value grows on the first and fifteenth of each month, reflecting the semiannual compounding. You will not see the value change daily, but if you check the same bond on the first of one month and the first of the next, you should see growth. Paper bonds do not show this growth visibly — the value is only revealed when you redeem or check it through the calculator.

What to do with mature bonds

Once your Series EE bond reaches 30 years and stops earning interest, you have several options. You can redeem it and deposit the money into a bank account or reinvest it in new bonds or other savings vehicles. You can also simply leave it in your TreasuryDirect account or in a safe place if it is a paper bond — there is no deadline to cash it in.

Some people hold mature bonds as a form of very safe, accessible savings. The money is still there, still backed by the U.S. government, and can be withdrawn whenever you need it. The downside is that it earns nothing, so if you have other savings goals or higher-yielding options, moving the money may make sense.

Frequently Asked Questions

Can I buy a Series EE bond and hold it longer than 30 years?

Yes, you can hold a Series EE bond indefinitely after the 30-year maturity date. The bond will not expire, and you can redeem it whenever you choose. However, it will not earn any interest after year 30, so the value remains fixed at whatever it reached on the maturity date.

Do I have to redeem my Series EE bond at 30 years?

No. The Treasury does not require you to redeem a mature bond. You can keep it as long as you want, though it earns nothing after maturity. You redeem it only when you decide to access the money.

What is the difference between a Series EE bond earning interest for 30 years and a Treasury bond maturing in 30 years?

Series EE bonds are savings bonds that compound interest semiannually and cannot be redeemed early without penalty. Treasury bonds are marketable securities that pay interest twice per year and can be sold on the secondary market before maturity, though you may lose money if rates have risen. Both mature in 30 years, but they work differently.

If I buy a Series EE bond in 2024, when does it stop earning interest?

A Series EE bond purchased in 2024 stops earning interest on the same date in 2054 — exactly 30 years later. The specific month and day depend on when you buy it, but the 30-year window is fixed from the issue date.

Can the interest rate on my Series EE bond change during the 30 years?

No. The interest rate on a Series EE bond is locked in on the day you purchase it and never changes for the life of the bond. Even if Treasury rates rise or fall after you buy it, your bond continues earning the same rate for all 30 years.
