What are savings bonds?

A savings bond is a particular type of bond through which individuals can lend money to the government and receive compounding interest in return. Unlike regular bonds, savings bonds accrue interest that is paid out once you redeem the bond.
Many people use savings bonds as a secure way to save money and earn interest over time. Savings bonds are useful for saving for college, funding a startup, saving for retirement, and more.

How savings bonds work

When you buy a savings bond, you lend the government money. In return, they pay you interest. Earned interest compounds for 30 years or until you cash the savings bond. A savings bond cannot be resold or redeemed by anyone other than the owner.
You can buy a savings bond from the U.S. government’s Treasury Department in the form of a paper savings bond or electronic savings bond. Different types of savings bonds come with different limits.

Pro tip

The more time a savings bond spends maturing, the more compound interest you earn. When buying a savings bond, consider how much money you can put away for the most time to maximize your returns. For example, if you’re planning on buying a home in the next five years, tying up the money you need for a down payment in a savings bond isn’t the best idea. If you want to save for your child’s education in 20 years, a savings bond can be a great tool to do so.

Types of savings bonds

There are two types of savings bonds issued in the United States. While similar, each has its advantages. You can purchase both types of savings bonds electronically through the U.S. Treasury’s website. These bonds are backed by the “full faith and credit” of the U.S. government. This means that, as long as the government keeps paying its debts and meeting its financial obligation, investors will receive what the bond terms promise them.

1. Series EE bonds

Series EE bonds, which become unattractive when inflation is high, are securities that have been sold by the U.S. Treasury since 1980. Any Series EE bond issued after May 2005 earns semiannual interest installments paid at fixed rates. In the right circumstances, they can be good for people wanting their money to work for them with minimal risk.
Regardless of the rate, the bond’s value doubles from its purchase price to its par value (face value) 20 years after the bond’s issue date. This guaranteed doubling means any Series EE bond held for 20 years will have an effective interest rate of 3.5%.

2. Series I bonds

Series I bonds are attractive because they help protect your money from inflation. The interest earned on I bonds depends on a combination of a fixed rate and an inflation rate. The fixed rate stays the same for the lifetime of the bond. The inflation rate adjusts twice per year. You can only buy series I paper bonds when you file your federal income taxes. You can purchase electronic bonds anytime.

Redeeming savings bond funds

One year after purchasing a savings bond, the owner can cash it in. However, with both series, any bond cashed in before five years of maturity loses the last three months of interest payments. Obviously, the longer you hold a savings bond, the more interest it accrues. The maximum term is 30 years.
When you’re ready to redeem an electronic savings bond, you can do so through the Treasury Department’s TreasuryDirect website. You can redeem paper bonds at most banks or credit unions or by sending them to the U.S. Treasury. To redeem a bond, you’ll need the bond itself, proof of identity, and, in special cases, proof that you are the named beneficiary for the bond.

Where to find the savings bond serial number

Thirty years is a long time to keep track of a piece of paper. It’s important to know your savings bond serial number in case the bond gets lost or damaged. The serial number can also help you calculate the value of your bond and find other important bond information.
On paper savings bonds, the alphanumeric serial number is located in the bottom right corner. It should be a 10-digit code containing letters and numbers. It’s important to keep a record of this number.
When you buy a new savings bond, write the serial number down and keep it in a safe, easy-to-remember place. You never know when you’ll need it throughout the lifetime of your bond.

Recovering lost or damaged savings bonds

You can use your bond serial number to recover, replace, or transfer savings bonds. If your paper bond is lost, stolen, or destroyed, you’ll need to file a claim with FS Form 1048. Required on this form are some key pieces of information about your bond. You must provide sufficient information to verify ownership and recover the bond.
Form 1048 asks for the bond serial number. If you don’t have it, you’ll be required to submit your month and year of purchase, Social Security number, name, and address. You must sign the form in the presence of an authorized certifying officer at a bank, trust company, or credit union. The U.S. Treasury Department will then reissue your bond electronically.
You can also convert paper bonds to electronic bonds for easy tracking and monitoring of your securities. Keep your account information and bond serial number and follow instructions on the U.S. Treasury website to make the easy switch.

Savings bond calculator

Whether you’re considering cashing out or you’re just curious, it’s helpful to know what the current value of your savings bond is. Your bond serial number isn’t mandatory to find this out, but it makes it more simple and easy. TreasuryDirect has a savings bond calculator tool that makes it easy to find out the exact value of your savings bond.
Navigate to the savings bond calculator tool on TreasuryDirect.gov. You can find it under “Resources & Tools,” or click here to go straight to it. Enter the series type, denomination, and issue month and year. Click “calculate,” and it will show you your exact bond valuation. If you don’t have your serial number, you can omit it from the calculator. It will still give you an estimated value based on the series, denomination, and issue date.
