What Is a Savings Bond?

Series I and Series EE explained · rates for bonds issued May 1, 2026 to October 31, 2026 · U.S. Treasury

A savings bond is a loan you make to the U.S. government. You buy it directly from Treasury rather than from a broker, it earns interest for up to 30 years, and when you want your money you redeem it back to Treasury for the principal plus everything it has earned.

What separates it from every other government bond is that it does not trade. A 10-year Treasury note has a price that moves every day and can be sold to someone else at a profit or a loss. A savings bond has no market price, no buyer other than Treasury, and no way to lose principal. It is registered to you by name, and that is the trade: complete safety and zero liquidity for the first year.

The Series EE Doubling Guarantee

The headline rate on a Series EE bond is 2.40%, which looks unremarkable. The guarantee attached to it is not: hold the bond exactly 20 years and Treasury guarantees it will be worth double what you paid, adding a one-time adjustment if the stated rate did not get it there.

Doubling over 20 years is an effective return of about 3.5% a year, which is the number that actually matters — and it is well above the quoted rate. The catch is that it is all-or-nothing on timing: redeem at nineteen years and you get the stated rate only. That makes an EE bond a poor instrument for money you might need and a reasonably strong one for a date you know in advance, such as a child starting college.

How to Buy

Both series are bought from TreasuryDirect, which is Treasury’s own account system rather than a brokerage. There are no fees and no intermediary. The minimum is $25 and you can buy any amount above that to the penny, up to $10,000 per series per calendar year, per Social Security Number.

The limit is per SSN, not per household, so a couple can buy twice that between them, and bonds bought for a child under their own SSN have their own limit. Because the cap is by calendar year, a purchase on December 31 and another on January 1 fall in different years.

Since January 1, 2025, savings bonds are electronic-only. Guidance suggesting you can take up to $5,000 in paper I bonds as part of a tax refund describes a route that no longer exists. Paper bonds issued before then remain perfectly valid.

When You Can Cash One

Neither series can be redeemed in the first 12 months at all — there is no early-withdrawal option, no penalty that buys you out of it. Between one and five years you can redeem but forfeit the last 3 months of interest. After five years there is no penalty.

At 30 years the bond stops earning interest entirely. This is the detail most worth acting on: a bond past final maturity is doing nothing, and a great many older paper bonds are still being held long after they stopped paying. Treasury publishes a Savings Bond Calculator that will tell you a paper bond’s current value and whether it has stopped earning.

Tax Treatment

Interest on both series is subject to federal income tax but exempt from state and local income tax, which is worth real money in a high-tax state. You are not taxed as the interest accrues — you can defer the whole liability until you redeem the bond or it reaches 30 years, whichever comes first.

Interest may also be fully or partly excluded from federal tax when used for qualifying higher-education expenses in the same year the bond is redeemed, subject to income limits and a requirement that the bond is registered to the parent rather than the student.

FAQ

What is a savings bond?
A savings bond is a loan you make to the U.S. government. You buy it directly from Treasury, it earns interest for up to 30 years, and you redeem it back to Treasury for your money plus the interest it has earned. Unlike a Treasury note or bond, it is not traded on any market, its value never falls, and it cannot be sold or transferred to another investor.
What is the difference between Series I and Series EE savings bonds?
A Series I bond pays a rate that moves with inflation, currently 4.26%. A Series EE bond pays a fixed rate, currently 2.40%, but carries a guarantee the I bond does not: if you hold it 20 years, Treasury guarantees it will have doubled, topping up the value if the fixed rate alone did not get there.
How much are savings bonds worth now?
For an electronic bond, the current value shows in your TreasuryDirect account. For a paper bond, Treasury publishes a Savings Bond Calculator that takes the series, denomination and issue date and returns the redemption value — including whether the bond has stopped earning interest.
Do savings bonds ever stop earning interest?
Yes, and this is the most common thing people miss. Both series stop earning at 30 years. A bond past that date is not accruing anything, so there is no reason to keep holding it — many older paper bonds are sitting in drawers earning nothing.
Can I still buy paper savings bonds?
No. Since January 1, 2025, savings bonds are electronic-only and are bought through a TreasuryDirect account. The route that let you take up to $5,000 of paper I bonds as part of a tax refund has ended, although a lot of published guidance has not caught up. Paper bonds bought before then remain valid and can still be redeemed.
Are savings bonds a good investment?
They are a savings instrument rather than an investment: no market risk, no price movement, a government guarantee, and a hard purchase cap. That makes them well suited to money you want protected from inflation and cannot afford to lose, and poorly suited to money you want to grow aggressively or access within a year.
