Between EE and I Bonds, I Bonds are the stronger pick for most buyers today because they track inflation in real time and free up after five years, while EE Bonds only pull ahead if you can commit to the full 20-year hold that triggers the Treasury’s doubling guarantee. Both are backed by the federal government, exempt from state and local income tax, and capped at $10,000 per person per year in electronic purchases. The right answer depends on your time horizon and whether you want inflation protection or a guaranteed lump sum.
The Core Difference in How Each Bond Earns
An EE Bond pays a fixed rate set on the day you buy it, and that rate stays locked for the life of the bond. Interest accrues monthly and compounds every six months. The real feature is the doubling guarantee: Treasury promises the bond will be worth twice what you paid after exactly 20 years, and if the fixed rate alone doesn’t get you there, Treasury makes a one-time adjustment at the 20-year mark to close the gap.1eCFR. 31 CFR Part 351 Subpart B – Maturities, Redemption Values, and Investment Yields of Series EE Savings Bonds On a $10,000 bond at today’s 2.50% fixed rate, compounding alone would produce around $16,400 after 20 years. Treasury bumps it to $20,000, an effective annual return of about 3.53%.2TreasuryDirect. EE Bonds Cash out earlier and you forfeit that adjustment, walking away with whatever the fixed rate alone has produced.
An I Bond earns through two components: a fixed rate that locks in at purchase and a variable inflation rate that resets every May 1 and November 1, based on changes in the Consumer Price Index for All Urban Consumers.3TreasuryDirect. I Bonds Treasury combines them using the formula fixed rate + (2 × semiannual inflation rate) + (fixed rate × semiannual inflation rate) to produce the composite rate the bond actually earns.4TreasuryDirect. I Bonds Interest Rates The composite rate can never drop below zero, so deflation freezes earnings rather than eating principal. Both bonds stop earning at 30 years.
When EE Bonds Win
EE Bonds make sense when you have a specific goal 20 years out and you want a guaranteed outcome. A 3.53% effective annual return on a risk-free instrument, locked in by Treasury, is genuinely hard to beat on a risk-adjusted basis. Nothing else in the market offers it.
The fit is especially clean for parents of young children. Buy EE Bonds when a child is a toddler, hold through college enrollment, and the 20-year timeline aligns almost perfectly. Layer in the education tax exclusion (see below) and the interest can escape federal tax entirely if you stay under the income thresholds.
The catch: EE Bonds are mediocre if you cash out early. At a 2.50% fixed rate, you’re earning less than a high-yield savings account for the first two decades. The whole value proposition depends on holding the full 20 years. If there’s any real chance you’ll need the money sooner, EE Bonds are the wrong vehicle.
When I Bonds Win
I Bonds are the better pick when you want safety with flexibility. They pay a competitive rate from day one, they adjust to inflation automatically, and they become penalty-free after five years instead of requiring a two-decade lockup.
For money you want to keep ahead of inflation without committing to a long horizon, I Bonds do the job once you’re past the mandatory 12-month lockup. They also outperform when inflation runs hot: in 2022, I Bonds briefly paid a composite rate above 9%, something EE Bonds could never match in real time. And I Bonds give you more room to buy, since paper I Bonds purchased through a tax refund sit outside the electronic cap.
The trade-off is uncertainty. If inflation stays low for years, the composite rate drops with it. The fixed component provides a small floor, but an I Bond bought during a low-inflation stretch could easily underperform an EE Bond’s guaranteed doubling. I Bonds reward volatility; EE Bonds reward patience.
What the Rates Look Like Right Now
EE Bonds issued from November 2025 through April 2026 carry a fixed rate of 2.50%.5TreasuryDirect. Fiscal Service Announces New Savings Bonds Rates, Series I to Series EE The rate has hovered between 2.10% and 2.70% since late 2022, a significant improvement over the 0.10% rate EE Bonds paid in the first half of 2022.6TreasuryDirect. EE Bond Interest Rates for Bonds Issued Since May 2005 The stated rate matters less than you’d think: the doubling guarantee still locks in a roughly 3.53% effective annual return at year 20 regardless of when you bought.
I Bond rates move more visibly. The composite rate for bonds issued May through October 2025 was 3.98%, built from a 1.10% fixed rate and a 2.86% annualized inflation rate.7TreasuryDirect. Fiscal Service Announces New Savings Bonds Rates, Series I to Series EE Because the inflation component resets every May and November, the current composite rate may differ; check TreasuryDirect before buying.
Watch the I Bond fixed rate closely if you’re planning a long hold. It has ranged from 0.40% in late 2022 to 1.30% in late 2023, and whatever fixed rate you lock in stays with the bond forever. A high fixed rate is 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 you can buy $10,000 in EE Bonds and $10,000 in I Bonds in the same year.8TreasuryDirect. How Much Can I Spend/Own? Electronic bonds are sold only through TreasuryDirect. The minimum purchase is $25, and you can buy in any amount down to the penny up to the cap.9TreasuryDirect. User Guide Sections 131 Through 140
I Bonds have a second channel. You can direct up to $5,000 of your federal tax refund into paper I Bonds by filing IRS Form 8888, in $50 increments.10Internal Revenue Service. Use Your Refund to Buy Savings Bonds That pushes one person’s annual I Bond ceiling to $15,000. EE Bonds have no paper option; $10,000 is the hard cap.
Trusts, LLCs, and other entities can each open their own TreasuryDirect account and buy up to $10,000 of each bond type per year under the entity’s tax identification number.11TreasuryDirect. TreasuryDirect FAQ A couple who each own a revocable trust can multiply their household exposure significantly. Entities cannot buy or receive gift bonds.
Holding Periods and Early-Redemption Penalties
Both EE and I Bonds lock up your money for the first 12 months. You cannot redeem either for any reason during that window.12TreasuryDirect. Cashing EE or I Savings Bonds If you cash in during years two through five, you lose the last three months of interest. After five years, no penalty.
Three months of interest is a mild penalty on paper. It can sting on an I Bond during a high-inflation stretch when those months represent real money. With EE Bonds, the three-month penalty isn’t the real cost of early redemption. Losing the doubling adjustment is. Cash an EE Bond at year 19 and you receive only what the fixed rate has generated, missing the potentially large payment Treasury would have made at year 20.
Tax Treatment
Both bonds share the same favorable tax setup. Interest is exempt from state and local income tax.13TreasuryDirect. Tax Information for EE and I Bonds Federal tax on the interest is deferred until you cash the bond or it reaches final maturity at 30 years, whichever comes first.14Internal Revenue Service. Topic No. 403, Interest Received That deferral lets interest compound without an annual tax drag, an advantage taxable savings accounts and CDs can’t offer.
You can elect to report the interest annually instead, but the election applies to every savings bond you own from that point forward. Few buyers benefit from making it.
The Education Exclusion
The most valuable savings-bond tax break is the education exclusion under 26 USC 135, which can eliminate federal income tax on the interest entirely if you use the proceeds to pay tuition and fees at an eligible higher-education institution in the same year you redeem.15Office 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 on the issue date. Bonds registered in a child’s name never qualify, even after the child turns 24. If you’re saving for a child’s college, register the bond in your own name.16TreasuryDirect. 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 married couples filing jointly, disappearing entirely at $116,800 and $182,650 respectively. Thresholds adjust annually.
Using Both Together
Nothing stops you from buying both in the same year. A common approach: max out I Bonds first for inflation protection and liquidity, then buy EE Bonds with money you’re confident you won’t touch for two decades. A married couple can purchase up to $40,000 in electronic bonds annually ($10,000 per spouse per bond type), plus another $10,000 in paper I Bonds if both direct $5,000 of their tax refunds. That’s $50,000 per household, all state-tax-exempt and compounding tax-deferred.
One thing to avoid regardless of which bond you pick: holding past 30 years. Both types stop earning at final maturity, and any bond sitting in a drawer beyond that point is losing purchasing power every day.12TreasuryDirect. Cashing EE or I Savings Bonds
