Choosing between EE and I Bonds comes down to one question: can you leave the money alone for 20 years? If yes, EE Bonds win because the Treasury guarantees your money will double at the 20-year mark, locking in an effective annual return of roughly 3.53% regardless of the stated fixed rate. If no, I Bonds are the better fit because they pay a competitive inflation-adjusted rate from day one and become penalty-free after five years instead of twenty. Both are backed by the federal government, both are capped at $10,000 per person per year in electronic purchases, and both are exempt from state and local income tax.
How Each Bond Earns Interest
EE Bonds pay a fixed rate set on the day you buy them, and that rate stays locked for the life of the bond. Interest accrues monthly and compounds every six months. The real feature, though, is the Treasury’s promise that your EE Bond will be worth twice what you paid after exactly 20 years. If the fixed rate alone doesn’t get you there, Treasury makes a one-time adjustment at year 20 to close the gap.1eCFR. 31 CFR Part 351 Subpart B – Maturities, Redemption Values, and Investment Yields of Series EE Savings Bonds At the current 2.50% fixed rate, compounding alone would produce roughly $16,400 on a $10,000 investment after 20 years. Treasury bumps that to $20,000.2TreasuryDirect. EE Bonds
Cash out before year 20 and you forfeit the doubling guarantee entirely. You get only what the fixed rate has accumulated. The bond then keeps earning at its fixed rate until it reaches final maturity at 30 years, when it stops entirely.1eCFR. 31 CFR Part 351 Subpart B – Maturities, Redemption Values, and Investment Yields of Series EE Savings Bonds
I Bonds work differently. The rate has two parts: a fixed rate that locks in at purchase and never changes, plus a variable inflation rate that resets every six months on May 1 and November 1.3TreasuryDirect. I Bonds The inflation component tracks the Consumer Price Index for All Urban Consumers, the same measure behind Social Security cost-of-living adjustments.4TreasuryDirect. Comparison of TIPS and Series I Savings Bonds Treasury combines the two into a composite rate using a formula that adds the fixed rate, twice the semiannual inflation rate, and a small cross-term.5TreasuryDirect.

Your principal is always protected. The composite rate can never drop below zero, even if deflation would push the inflation component deeply negative.3TreasuryDirect. I Bonds Like EE Bonds, I Bonds earn for 30 years and then stop.
When to Choose EE Bonds
EE Bonds fit a specific financial goal 20 years out with a guaranteed outcome. A 3.53% effective annual return on a risk-free instrument held for two decades is hard to match on a risk-adjusted basis, and the doubling guarantee is available nowhere else in the market.
The alignment with saving for a young child’s college is almost exact. Buy EE Bonds when the child is a toddler, hold until college, and if the federal education exclusion applies to you, the doubled proceeds can come out tax-free.
The catch is that EE Bonds are mediocre if you cash out early. At a 2.50% fixed rate, you earn less than a high-yield savings account for the first two decades. The entire value proposition collapses without the full 20-year commitment. If there’s any real chance you’ll need the money sooner, an EE Bond is the wrong vehicle.
When to Choose I Bonds
I Bonds are the stronger pick when you want safety with flexibility. They pay a competitive rate from day one, protect purchasing power automatically, and become penalty-free after five years rather than twenty.
For emergency fund money you want to keep ahead of inflation, I Bonds work well once you get past the mandatory one-year lockup. They also shine when inflation is elevated or uncertain. During 2022, I Bonds briefly offered a composite rate above 9%, something EE Bonds could never match in real time.
I Bonds also give you more annual buying power. On top of the $10,000 electronic cap, you can direct up to $5,000 of a federal tax refund into paper I Bonds using IRS Form 8888.6Internal Revenue Service. Use Your Refund to Buy Savings Bonds EE Bonds have no paper option.
The downside is uncertainty. If inflation runs low for an extended stretch, your composite rate drops with it. The fixed component gives a small floor, but an I Bond bought during a low-inflation era can underperform the EE Bond’s guaranteed doubling over 20 years. I Bonds reward volatility; EE Bonds reward patience.
Current Rates
EE Bonds issued from November 2025 through April 2026 carry a fixed rate of 2.50%.7TreasuryDirect. Fiscal Service Announces New Savings Bonds Rates, Series I to Series EE The rate has moved between 2.10% and 2.70% since late 2022, a sharp improvement over the 0.10% rate on EE Bonds issued in the first half of 2022.8TreasuryDirect. EE Bond Interest Rates for Bonds Issued Since May 2005 The stated rate matters less than it looks: the doubling guarantee produces the same effective ~3.53% annualized return at year 20 regardless of what fixed rate your bond started with.
I Bond rates move more. The composite rate for I Bonds issued from May through October 2025 was 3.98%, built from a 1.10% fixed rate and a 2.86% annualized inflation rate.9TreasuryDirect. Fiscal Service Announces New Savings Bonds Rates, Series I to Series EE Because the inflation component resets each May and November, the current composite rate may differ. Check TreasuryDirect for the latest figure before you buy.
The I Bond fixed rate has ranged from 0.40% in late 2022 to 1.30% in late 2023. That fixed component matters more than the composite rate for long-term planning because it stays with your bond for the full 30 years. A high fixed rate at purchase gives you a permanent premium on top of whatever inflation does later.
Purchase Limits and How to Buy
Both bond types cap electronic purchases at $10,000 per person per calendar year, tracked by Social Security number. The limits are separate, so one person can buy $10,000 of each type in the same year.10TreasuryDirect. How Much Can I Spend/Own? Electronic bonds are sold only through TreasuryDirect, the Treasury’s online platform. The minimum purchase is $25, with any amount down to the penny up to the annual cap.11TreasuryDirect. User Guide Sections 131 Through 140
The paper I Bond option through a tax refund adds up to $5,000 more in I Bond buying power per year, with paper bonds sold in $50 increments.6Internal Revenue Service. Use Your Refund to Buy Savings Bonds That brings one person’s annual I Bond ceiling to $15,000, against a hard $10,000 for EE Bonds.
Trusts, LLCs, and other entities can each open their own TreasuryDirect account and buy up to $10,000 in each bond type per year using the entity’s tax identification number.12TreasuryDirect. TreasuryDirect FAQ A married couple with revocable trusts can buy personally and through both trusts, multiplying household exposure. Entity accounts require a taxpayer identification number and an authorized account manager who can act independently.13TreasuryDirect. User Guide Sections 291 Through 300 Entities cannot buy bonds as gifts or receive them.
Lockups and Early-Redemption Penalties
Both bond types lock up your money for the first 12 months. You cannot redeem either bond before the one-year mark for any reason.14TreasuryDirect. Cashing EE or I Savings Bonds Cash in during years two through five and you lose the last three months of interest as an early-redemption penalty. After five years, there’s no penalty.
The three-month penalty sounds mild, but it can sting with I Bonds during high-inflation stretches when those months represent real earnings. With EE Bonds, the three-month penalty isn’t the real cost of cashing out early. Losing the doubling guarantee is. Redeem at year 19 and you walk away with only what the fixed rate has produced, missing the adjustment Treasury would have made at year 20.
Both bonds stop earning entirely at final maturity after 30 years. Any bond held past that point is just losing ground to inflation.14TreasuryDirect. Cashing EE or I Savings Bonds
Shared Tax Treatment
Both bonds get the same favorable federal tax treatment. Interest is completely exempt from state and local income tax.15TreasuryDirect. Tax Information for EE and I Bonds Federal income tax on the interest is deferred until you cash the bond or it reaches final maturity, whichever comes first.16Internal Revenue Service. Topic No. 403, Interest Received That deferral lets interest compound without an annual tax drag, something a taxable savings account or CD can’t offer.
You can elect to report interest annually, but once you make that choice it applies to every savings bond you own going forward. Few people find that worthwhile.
The Education Exclusion
The most valuable tax feature available for either bond is the federal education exclusion, which can wipe out federal income tax on the interest entirely. To qualify, you must use the proceeds to pay tuition and fees at an eligible higher-education institution in the same year you redeem the bond.17Office of the Law Revision Counsel. 26 USC 135 – Income From United States Savings Bonds Used to Pay Higher Education Tuition and Fees
Several requirements trip people up:
- The bond must have been issued after 1989.
- The bond owner must have been at least 24 years old when the bond was issued. Bonds registered in a child’s name never qualify, even after that child turns 24. If you’re saving for a child’s college, register the bond in your own name.18TreasuryDirect. Savings Bonds Using Bonds for Higher Education
- Married couples must file jointly to claim the exclusion.
The exclusion phases out at higher incomes. For the 2026 tax year, the phase-out begins at a modified adjusted gross income of $101,800 for single filers and $152,650 for joint filers, with the exclusion disappearing entirely at $116,800 and $182,650. These thresholds adjust annually for inflation.
Using Both Together
Nothing stops you from buying both types in the same year, and for many savers that’s the right move. A common approach is to max out I Bonds first for inflation protection and five-year liquidity, then add EE Bonds with money you’re confident you won’t touch for 20 years. A married couple can purchase up to $40,000 in electronic bonds annually ($10,000 per person per bond type), plus another $10,000 in paper I Bonds if both spouses direct $5,000 of their tax refunds. That’s $50,000 in savings bonds per household, all exempt from state tax and compounding tax-deferred.
