Free Guide to Understanding Your Savings Bonds Value

How Savings Bonds Work and Why People Own Them

Savings bonds are loans you give to the U.S. government. When you buy a bond, you're lending money to the federal government. In return, the government promises to pay you back that money plus interest over time. This arrangement has existed since 1935, and millions of Americans have purchased bonds over the decades.

There are currently two main types of savings bonds available for purchase: Series EE bonds and Series I bonds. Series EE bonds earn a fixed rate of interest that's set when you purchase the bond and remains the same throughout the bond's life. Series I bonds, introduced in 1998, have an interest rate that changes every six months based on inflation rates. Both types are backed by the full faith and credit of the U.S. government, meaning the government guarantees it will repay the bonds.

People purchase savings bonds for various reasons. Some view them as a safe place to store money because they're backed by the government and carry virtually no risk of default. Others use bonds as a way to save for future goals like education expenses or retirement. Parents and grandparents often give bonds as gifts to children, with the bonds maturing over years or decades. According to the U.S. Department of the Treasury, over $200 billion in Series EE bonds and Series I bonds are currently held by Americans.

The bonds you own today may have been purchased years or even decades ago. Understanding what those bonds are actually worth requires knowing several key factors: the bond's series type, the purchase price, when it was bought, and the current interest rates. Bonds continue earning interest for up to 30 years, so even old bonds sitting in a drawer may have increased significantly in value.

Practical Takeaway: Savings bonds are government-backed loans where you lend money and receive interest payments. The value of your bonds depends on their type, age, and current market conditions. Begin by identifying which bonds you own and gathering their purchase information.

Determining Your Bond's Purchase Price and Series Type

The first step in understanding your bond's current value is identifying what you actually purchased. The purchase price—also called the issue price—differs based on the bond series. For Series EE bonds purchased after May 2003, you pay face value. This means if you bought a $100 bond, you paid $100. However, Series EE bonds purchased before May 2003 were sold at half their face value, meaning you paid $50 for a $100 bond.

Series I bonds are always purchased at face value. If you bought a $50 I bond, you paid exactly $50. The interest earnings accumulate on top of this base amount. Bonds can be purchased in denominations of $25, $50, $75, $100, $200, $500, $1,000, $5,000, and $10,000.

Physical paper bonds display the series letter (EE or I) clearly on the certificate. The series appears in the upper right corner of the bond. The purchase date is also printed on the bond, typically near the bottom. If you have paper bonds, locate these details. If your bonds are electronic—stored in TreasuryDirect accounts—you can log into your account to view all details, or contact the Treasury Department for a statement.

For bonds purchased before you had an online account, you might have only a paper certificate. Some people lose track of bonds over years or decades. If this is your situation, the Treasury Department maintains records of uncashed bonds. You can search for lost or forgotten bonds through the Treasury Hunt tool or by contacting the Bureau of the Fiscal Service. Provide as much information as you have: approximate purchase year, estimated amount, and the last known owner's name.

Practical Takeaway: Write down the series type (EE or I), purchase date, and purchase price for each bond you own. If information is unclear or bonds are missing, search Treasury Department records using the online Hunt tool or request a statement directly from the Bureau of the Fiscal Service.

Understanding Interest Rates and How Bonds Earn Money

Bonds earn money through interest rates set by the U.S. Department of the Treasury. The interest rate determines how much extra money you'll receive beyond your original purchase price. However, Series EE and Series I bonds work differently.

Series EE bonds earn a fixed rate that never changes. When you purchase an EE bond, the Treasury announces the interest rate for that purchase period (rates change every six months in May and November). That rate stays the same for the entire 30-year life of the bond. For example, if you bought a Series EE bond in November 2023 at a 4.30% rate, that bond will earn 4.30% interest annually for all 30 years. As of November 2024, new Series EE bonds earn 4.30% annual interest.

Series I bonds operate differently because they're designed to protect against inflation. I bonds have a composite rate made of two parts: a fixed rate and an inflation rate. The fixed rate never changes and applies for the entire 30 years. The inflation rate, however, changes every six months based on the Consumer Price Index (CPI). The CPI measures how prices for goods and services change over time. When inflation rises, your bond's interest rate increases. When inflation falls, the rate decreases. As of November 2024, Series I bonds earn a composite rate of 5.27% annually (the fixed rate is 1.17% and the inflation rate is 4.10%).

Interest compounds semiannually for both bond types. This means every six months, the interest you've earned gets added to your bond's value, and then you earn interest on that larger amount. Over 30 years, this compounding effect significantly increases your total return. A $100 Series EE bond at 4.30% interest grows differently than a $100 Series I bond, depending on inflation rates during the ownership period.

Practical Takeaway: Series EE bonds have fixed interest rates that never change. Series I bonds have rates that adjust every six months based on inflation. Both types compound interest semiannually. Look up the interest rate from your bond's purchase date to calculate potential growth, and understand that older bonds may earn very different rates than new bonds.

Calculating Your Bond's Current Value

Once you know your bond's series, purchase price, purchase date, and interest rate, you can calculate its current value. The calculation differs slightly for Series EE and Series I bonds.

For Series EE bonds with a fixed interest rate, the calculation is straightforward: multiply your purchase price by (1 + annual interest rate) raised to the power of the number of years owned, compounded semiannually. For a simpler approach, the Treasury Department provides value calculators on its website. You enter the series, issue date, and denomination, and the calculator shows the current value. For example, a $100 Series EE bond purchased in January 2000 at a 5.00% rate would be worth approximately $267 in January 2024 after 24 years of growth.

For Series I bonds, the calculation is more complex because the interest rate has changed multiple times. The composite rate (fixed rate plus inflation rate) has varied from a low of -0.11% in May 2022 to highs over 9% in 2023-2024. The Treasury website's savings bond calculator accounts for all historical rate changes automatically. You simply provide your bond's issue date and denomination.

The Treasury Department maintains a searchable database called "Savings Bond Calculator" on TreasuryDirect.gov. This tool is the most reliable method for determining current values. Enter your bond information, and the calculator displays the exact current value and the date that value was determined. The values update monthly based on new interest rate announcements.

It's important to note that bonds don't reach their full face value immediately. Series EE bonds take approximately 17-20 years to double in value (reach face value if purchased at half price). Some older EE bonds purchased decades ago may have already exceeded their face value by significant amounts. Series I bonds purchased at face value are worth at least their face value from the start, plus accumulated interest.

Practical Takeaway: Use the Treasury Department's Savings Bond Calculator at TreasuryDirect.gov to determine your bond's exact current value. Enter the series, issue date, and denomination. The calculator accounts for all interest rate changes and compounds interest automatically.
