Savings bonds are a type of bond, or debt security, issued by the U.S. government. Unlike typical bonds that pay interest regularly, a savings bond is a “zero coupon” bond, meaning that it pays interest only when it is redeemed by the owner. The bond is non-transferrable, so you can’t sell it to another saver, another feature that distinguishes it from more typical bonds.

Here’s our guide to getting started with savings bonds and what you need to know if you’re considering them as part of your personal savings plan.

Savings bonds FAQ

What is a savings bond?

Savings bonds are an easy way for individuals to loan money directly to the government and receive a return on their investment. The bonds are sold at their face value. So if you want to invest $50, you buy a $50 bond, and then you will begin accruing interest on that amount. As interest builds up on the account, you will compound your gains, so your interest earns interest.

But a savings bond differs from a traditional bond in several key ways:

  • Unlike a traditional bond, which pays out cash interest regularly, a savings bond does not pay until you redeem it (although the bond accrues interest over time).
  • While a traditional bond matures on a specific date and then ceases to exist, a savings bond can mature and then continue to exist.
  • A savings bond can continue to accrue interest until it is redeemed, or up to 30 years after it was issued.
  • With traditional bonds, the owner pays taxes on interest payments, but an owner of a savings bond does not pay taxes until the bond is redeemed.
  • Unlike most traditional bonds, the interest on a Series EE or Series I savings bond is subject to income taxes only at the national level, not at the state level or lower.
  • A buyer of traditional bonds can purchase any amount at any time, but purchasers of savings bonds are limited to buying $10,000 in bonds of each series (so $20,000 total) in any one year.

How do savings bonds work?

Savings bonds work by paying you interest for the bond. While the savings bond accrues interest over time, it does not pay until you redeem it.

Savings bonds can be redeemed only by the owner, and you will not be able to sell them to or buy them from another person. The bond can be redeemed directly with the government, or in the case of a paper bond, with the government or a financial institution.

Savings bonds can be purchased directly from the U.S. government, via the Treasury’s website at Series EE and Series I bonds can be purchased in electronic form, while Series I bonds are also available to be purchased in paper form with your IRS tax refund.

You can buy an electronic Series EE or Series I bond in any denomination over $25 in one cent increments. For example, you could purchase a bond for $75.34.

However, paper I bonds come in only denominations of $50, $100, $200, $500 and $1,000.

If your paper bond is lost, stolen, destroyed or otherwise mutilated, you can request a replacement electronic bond.

Different types of savings bonds

U.S. savings bonds come in a few series, only two of which are still issued:

Series E bonds

The U.S. government first issued these bonds to fund itself during World War II, and it continued to sell them until 1980, when Series EE bonds superseded them. These bonds are no longer issued.

Series EE bonds

Series EE bonds were first issued in 1980 and continue to be issued today. These bonds pay either a fixed rate or a variable rate, depending on when they were issued. Series EE bonds issued after May 2005 earn a fixed rate of interest.

Series I bonds

Series I bonds provide a greater level of protection against inflation than do Series EE bonds: They provide not only a fixed interest rate but also a variable rate that’s based on the Consumer Price Index for urban consumers.

How to cash in savings bonds

Both Series EE and Series I bonds can be cashed in once they are at least twelve months old. However, if you cash in either series before you’ve owned them five years, you will lose the last three months of interest payments as a penalty.

Both series of bonds earn interest for as long as 30 years. The longer you hold the bond, the more it will be worth, up to that 30-year time limit.

Paper bonds can be cashed at most local financial institutions, while electronic bonds can be cashed on the Treasury website. Simply log in to your account and follow the instructions for redeeming the bond. The cash will be credited to your checking or savings account within two business days of the redemption date.

With electronic bonds, you will have to redeem at least $25 in bonds, while no limit typically exists for the amount of paper bonds you can cash in a single transaction. However, the bank cashing the bonds may impose a restriction on how much you can redeem at one time.=

Are savings bonds a good investment?


The biggest advantage of savings bonds is the absolute security of them. They’re issued directly by the U.S. government and are backed 100 percent by its “full faith and credit.”

Savings bonds are subject to income tax only at the federal level, not at state or local levels. However, if your state has any estate or inheritance taxes, the bonds are subject to them.

In addition, you may use savings bonds to pay for higher education expenses and thereby avoid paying taxes on some or all of the interest on the bonds. (Here are more details.)

Series I bonds offer some protection against inflation because their price adjusts in response to changes in the Consumer Price Index for urban consumers. If inflation rises, the yield on Series I bonds will be ratcheted up. If inflation declines, so will the rate on the bond.

Series EE bonds have a special feature: the Treasury guarantees that an electronic EE bond issued in June 2003 or later can be redeemed for at least twice the face value. If the interest rate is not sufficient to grow the bond to twice its value, then the Treasury will make a one-time adjustment at the bond’s 20th anniversary to make up the difference. In effect, if you hold a Series EE bond for 20 years, you would earn an annual yield of at least 3.5 percent.


The biggest disadvantages of savings bonds are the relatively low yields and the inflexibility.

Rates on Series EE bonds issued between November 2020 and April 2021 earn just 0.1 percent. Meanwhile, Series I bonds issued between November 2020 and April 2021 offer a yield of 1.68 percent, and this yield will fluctuate depending on the Consumer Price Index for urban consumers.

Bonds are also relatively inflexible. They cannot be redeemed at all in less than a year and will suffer a penalty of the last three months’ interest if redeemed in less than five years.

Bonds vs. savings accounts

Pros and cons of bonds

The biggest positive of savings bonds relative to savings accounts is that you can achieve a higher yield with Series I bonds. These bonds offer a fixed interest rate and then an additional floating rate that adjusts with inflation. Many savings accounts offer lower yields than Series I bonds.

Plus, as already mentioned, bonds are backed by the U.S. government, so they’re as safe of an investment as you can get.

On the downside, savings bonds are inflexible because they must be held for at least a year, and the owner will pay a penalty of three months’ interest if redeemed before five years.

In addition, savers can earn more on a savings account than from a Series EE bond (unless they are able to take advantage of the bond’s special 20-year privilege.)

Pros and cons of savings accounts

Two big positives of a savings account include its high level of flexibility and its high level of safety. Savings accounts are backed by the FDIC, which insures the account up to $250,000 per depositor per institution. In addition, savers can withdraw money from the account up to six times per month without penalty, giving them access to their money while still earning interest.

Plus, a savings account may pay better interest than a savings bond, especially if you do just a little bit of legwork to find a high-yield account. (That’s easy to do on Bankrate.)

The downside of a savings account is that its yield will fall as interest rates fall, so your return might not beat inflation, whereas the floating, inflation-adjusted yield on a Series I bond helps mitigate this risk.

Bottom line

Savings bonds are among the safest investments, as safe as any government-backed type of investment such as high-yield savings accounts, CDs or other insured bank products. Savers should carefully check the interest rate offered by their bonds, since rates on different series can vary markedly.

Those considering savings bonds might also consider CDs, with the hopes of finding a higher interest rate and more flexibility. Here are the highest-yielding CDs tracked by Bankrate.
