Understanding U.S. Savings Bonds: The Basics

Savings bonds are debt securities issued by the U.S. Department of the Treasury. When you purchase a savings bond, you're essentially lending money to the federal government. In return, the government pays you back with interest over time. There are two main types of savings bonds available to individual investors: Series EE bonds and Series I bonds.

Series EE bonds have been sold to the public since 1941. These bonds are sold at face value, meaning if you buy a $100 bond, you pay $100 upfront. The bond earns interest over time, and after 20 years, the government guarantees the bond will be worth at least double your original purchase price. This feature is unique to Series EE bonds and provides a minimum return on your investment.

Series I bonds, introduced in 1998, are designed to protect your purchasing power against inflation. The interest rate on I bonds consists of two components: a fixed rate and an inflation rate. The inflation rate changes every six months based on the Consumer Price Index. Currently, I bonds earn a combined rate that reflects both these components. For example, if the fixed rate is 1.06% and the inflation rate is 2.4%, your total rate would be approximately 3.46%.

Both bond types are issued in electronic form through TreasuryDirect, the official website of the U.S. Department of the Treasury. You can view your bonds online at any time, and there's no physical paper to lose or manage. The minimum purchase is $25 for electronic bonds, and you can buy up to $10,000 in electronic bonds per calendar year through TreasuryDirect.

Practical Takeaway: Learn the difference between EE and I bonds before deciding which type might fit your situation. EE bonds offer predictable growth with a doubling guarantee, while I bonds provide inflation protection. Understanding these differences helps you make informed decisions about whether savings bonds align with your financial goals.

How Savings Bonds Earn Interest and Grow Over Time

Interest on savings bonds works differently than interest on a traditional savings account. With savings bonds, the interest is compounded monthly, but you don't receive it in regular payments. Instead, the interest is added to the bond's value, and you receive the full amount—both principal and interest—when you cash in the bond or when it reaches final maturity.

For Series EE bonds, the interest accrues for 30 years. This means your money continues to grow even after 20 years, when the government's doubling guarantee takes effect. After 30 years, the bond stops earning interest and reaches what's called final maturity. Many people hold EE bonds longer than 20 years to continue receiving interest growth.

Series I bonds earn interest for 30 years as well. Because the inflation rate adjusts every six months, your earnings can vary. When inflation is high, I bonds earn more. When inflation is low, the earnings are lower, but they never go negative. This means you won't lose money through deflation—a key feature that differentiates I bonds from other investments.

Here's a concrete example: If you purchased a $100 Series EE bond today, and it earned an average rate of 2% annually, after 20 years it would be worth approximately $149. After 30 years, it would be worth roughly $181. However, actual rates change over time, so your results would depend on the rates when you purchased the bond and how rates change while you hold it.

For I bonds, the calculation is more complex because the rate changes. If you bought a $100 I bond when the rate was 4.3%, after one year it might be worth around $104.30. When the rate adjusts in six months, that new rate applies to your entire balance going forward.

Practical Takeaway: Understand that savings bond interest compounds but doesn't arrive in your bank account monthly. Your money grows silently in the background. This makes savings bonds useful for people who want their money to grow without needing regular interest payments for living expenses.

Purchasing Savings Bonds Through TreasuryDirect

TreasuryDirect (www.treasurydirect.gov) is the only official place to purchase new savings bonds directly from the U.S. government without paying fees or commissions. Setting up an account is straightforward and involves providing basic personal information including your Social Security number, address, and banking details.

To create a TreasuryDirect account, you'll need to establish a login username and password, set up security questions, and verify your email address. The process takes roughly 15 to 20 minutes. You must be at least 18 years old and have a valid Social Security number. Non-citizens with U.S. tax identification numbers may also open accounts.

Once your account is active, you can purchase bonds using funds from your bank account. TreasuryDirect links directly to your bank, and when you purchase a bond, the money is drawn electronically from your account. You can purchase bonds at any time during the year, with a few exceptions (certain holidays and Treasury system maintenance days).

The annual purchase limit is $10,000 per calendar year in electronic bonds for each Social Security number. You can purchase these bonds in any denomination from $25 up to $10,000 (in $25 increments). So, for example, you could buy a single $10,000 bond, or you could divide that into four $2,500 bonds, or any other combination that totals no more than $10,000.

Your TreasuryDirect account serves as your record of ownership. You can log in anytime to check the current value of your bonds, see how much interest they've earned, and review important dates like when they mature or become redeemable. This online access means you don't need to keep paper documents in a safe deposit box.

Practical Takeaway: Visit TreasuryDirect directly rather than through third-party websites. There's no advantage to purchasing through other platforms, and doing so may result in fees or delays. Direct purchase keeps more of your money working for you.

Cashing In Your Savings Bonds: Rules and Timing

You can cash in a savings bond at almost any time, but there are rules about when and how much you receive. For Series EE bonds, you should wait at least one year before cashing in. If you cash in an EE bond within five years of purchase, you'll lose three months of interest as a penalty. After five years, there's no penalty.

Series I bonds have a one-year holding requirement. You must keep an I bond for at least one year before you can cash it in. Additionally, if you cash in an I bond within five years of purchase, you'll also forfeit three months of interest. Like EE bonds, after five years, you can cash in without this penalty.

To cash in your bonds, you use your TreasuryDirect account. The process is electronic and relatively quick. You authorize the sale, and the funds are deposited directly into your bank account, typically within a few business days. You'll receive the full current value of the bond, including all accrued interest up to that point.

When you cash in a bond, you'll receive tax forms showing how much interest you earned. This interest is subject to federal income tax and must be reported on your annual tax return. Savings bond interest is not subject to state or local income tax, which is one advantage over certain other types of investments.

If you inherit savings bonds from someone, the rules for cashing them in remain the same. You can cash in inherited bonds at any time, though inherited EE bonds may have special considerations regarding when the interest was actually earned. It's worth consulting a tax professional if you inherit bonds to understand the tax implications.

Practical Takeaway: Plan to hold your savings bonds for at least five years if possible, so you avoid the three-month interest penalty when cashing in. If you need money sooner, you can still cash in the bond, but you'll receive less than if you'd waited out the five-year window.

Tax Treatment and Financial Planning Considerations

The interest you earn on savings bonds is subject to federal income tax, but the taxation timing and method differ from many other investments. You have two options for reporting interest on your federal tax return: you can report it
