I Bonds vs EE Bonds: Which to Buy in 2026

1. Our verdict on I bonds vs EE bonds

Quick Answer: Our pick is the I bond for almost every buyer in 2026. It pays 4.26% today against 2.40% for the EE bond, and it adjusts when prices rise. The EE bond wins in one narrow case only: money you are certain you will not touch for two full decades.

I bonds vs EE bonds looks like a coin flip at first. Same $10,000 yearly cap, same 12-month lock, same three-month exit penalty, same website. The difference sits in how each one earns.

An I bond earns a small fixed rate plus an inflation rate that resets twice a year. An EE bond earns one fixed rate plus a promise that it will be worth double after 20 years. The two designs pay off on completely different schedules.

This guide prices I bonds vs EE bonds on the rates Treasury set for May through October 2026, then runs $10,000 through each across 30 years. Every figure traces to a named public source, the same standard behind every investing guide we publish at DollarVisor. No company pays for placement here.

If you want the trade-off explained out loud first, this walkthrough covers it well.

2. What is the difference between I bonds and EE bonds?

Quick Answer: An I bond pays a fixed rate plus an inflation rate that Treasury resets every six months, so the payout moves with prices. An EE bond pays one fixed rate for 20 years and is then adjusted, if needed, so it is worth at least twice what you paid.

Both are US savings bonds, backed by the federal government, sold only through TreasuryDirect, and capped at $10,000 per person per year for each series. Neither trades on a market, so neither can lose value on paper the way a Treasury note in a bond ladder can.

What separates them is the engine.

• The I bond has two moving parts. A fixed rate, set at purchase and locked for the bond’s life, plus an inflation rate rebuilt from CPI-U every May and November. Right now that is 0.90% fixed plus a 3.34% annualized inflation piece.
• The EE bond has one part and a promise. A single fixed rate for the first 20 years, currently 2.40%, plus Treasury’s guarantee that the bond will be worth double its purchase price at the 20-year mark.
• Only one of them tracks your grocery bill. If inflation runs hot for a decade, the I bond follows it up. The EE bond keeps paying 2.40% no matter what prices do.

That last point is the whole design behind I bonds vs EE bonds: one bond for people who fear inflation, one for people who want a known number in 20 years.

3. What does each bond pay right now?

Quick Answer: I bonds issued May through October 2026 pay a 4.26% composite rate for their first six months. EE bonds issued in the same window pay 2.40% a year. Held for exactly 20 years, the EE bond’s doubling promise works out to about 3.53% a year.

Read the top two rows together. The 4.26% headline is not a rate you keep. It is 0.90% locked for 30 years plus an inflation piece that gets rebuilt in November.

The EE bond rows work in reverse. The 2.40% is real and locked, but the doubling promise adds to it only if you reach year 20.

A plain 5-year Treasury pays 4.33% today. Both savings bonds are sold into a market that already pays more for less patience.

4. $10,000 in each bond, year by year

Quick Answer: On our projection, $10,000 in I bonds stays ahead of $10,000 in EE bonds for the first 19 years, by roughly $3,300 at the widest point. The EE bond overtakes only at year 20, holds a lead worth a few hundred dollars, then falls behind again.

One row does all the work. At year 19 the EE bond is worth $15,735, which is what 2.40% actually builds. At year 20 it is worth $20,000, because Treasury writes in the difference.

That single adjustment is worth $3,885 on a $10,000 bond. It is also the only reason the EE bond ever leads. Wait a year too little and you collect none of it.

5. The doubling guarantee is a cliff, not a ramp

Quick Answer: Treasury’s promise that an EE bond doubles in 20 years is not paid out gradually. It arrives as one adjustment at the 20-year mark. Redeem at 19 years and 11 months and you earn 2.40%, not the 3.53% the guarantee implies.

Most write-ups treat the doubling as a headline yield. It is better read as an option with one exercise date.

A 2.40% rate compounded twice a year turns $10,000 into $16,115 after 20 years. Treasury’s guarantee tops that up to $20,000. So the 3.53% figure is real, but only for a holder who reaches the exact anniversary.

Three practical consequences follow from that shape:

1. Partial credit does not exist. The guarantee is binary. There is no reduced version for holding 18 years.
2. Your yield swings on one date. Moving your sale from month 239 to month 240 changes your annual return from 2.40% to 3.53%.
3. Life gets a vote. Twenty years covers a job change, a house, a divorce, a medical bill. Any of those can force an early sale.

This is where I bonds vs EE bonds usually goes wrong. Writers line up 3.53% against the I bond’s 4.26% and call it close. It is not, because those are not the same kind of number. One is a guaranteed rate you might never collect. The other is a floating rate you earn every six months whether you sell or not.

6. How both rates have moved since 2024

Quick Answer: The gap has widened every reset since late 2024. I bond composite rates rose from 3.11% to 4.26% while EE bond rates drifted from 2.60% down to 2.40%. The I bond’s fixed rate, though, has fallen from 1.20% to 0.90%.

The gap column is the easy read: 0.51 points, then 1.28, then 1.53, then 1.86. Every reset since late 2024 has pushed the I bond further ahead.

The fixed-rate column matters more for anyone buying to hold. It has slipped from 1.20% to 0.90%, so a buyer in late 2024 locked a permanent 0.30-point edge that no future reset gives back.

7. The rules side by side: limits, locks and taxes

Quick Answer: The rules are nearly identical. Both cap at $10,000 per person per year and lock your money for 12 months. Both charge three months of interest if you sell before five years, and both are free of state and local income tax.

Two rows deserve a second look. Separate limits mean a couple can put away $40,000 a year across I bonds and EE bonds, more room than most people assume. The state tax exemption is worth real money in a high-tax state.

The deferral is useful too. You owe no federal tax until you cash the bond or it stops earning at 30 years, so you choose the year the income lands.

8. Where buyers get this choice wrong

Quick Answer: Four mistakes come up again and again on I bonds vs EE bonds. Buyers chase the I bond’s headline rate, treat the EE doubling as a normal yield, forget the 12-month lock, or buy with money that has a job next year.

• Chasing the composite rate. The 4.26% is a six-month rate, not an annual one. Buy in August and you earn 4.26% annualized until the reset, then whatever November brings.
• Reading 3.53% as a rate. It only exists at the 20-year line. Anyone who might sell earlier should compare the EE bond at 2.40%, which loses to almost everything.
• Forgetting the 12-month lock. Neither bond can be cashed for a full year, which rules them out as an emergency fund substitute.
• Buying the maximum in one go. With a $10,000 annual cap, spreading purchases across two calendar years buys two different fixed rates. That is dollar-cost averaging applied to a rate you cannot otherwise diversify.
• Ignoring what else is on the shelf. A five-year CD or a Treasury note may pay more today with a shorter commitment.

One more trap: savings bonds get bought as gifts and forgotten. Interest stops entirely at 30 years, and an EE bond that sails past its 20-year date unnoticed still earns only 2.40% for the rest of its life.

9. Our verdict on who should buy which

Quick Answer: Buy I bonds for money you want protected from inflation over five to fifteen years. Buy EE bonds only for a dated goal exactly 20 years out, such as a newborn’s college fund. Buy neither for money you need within a year.

Three profiles cover most readers.

1. Saving for something five to fifteen years away. Buy I bonds. The inflation link protects what the money can actually buy, and you keep the option to sell after year five with no penalty.
2. Funding a goal on a fixed date about 20 years out. EE bonds have a genuine case. A bond bought for a newborn matures around the first tuition bill, and doubling is a number you can plan against. Pair it with a wider long-term plan.
3. Holding cash you might need this year. Buy neither. The 12-month lock disqualifies both, whatever the headline rate says.

If you are still torn on I bonds vs EE bonds, use the split our numbers support: the I bond is the default, the EE bond a specialist tool for one date. Nothing in the current rate table argues for making EE bonds your main holding.

10. Frequently Asked Questions

1. Are I bonds or EE bonds better in 2026?

On I bonds vs EE bonds, I bonds are better for most buyers in 2026. Bonds issued May through October 2026 pay a 4.26% composite rate against 2.40% for EE bonds. EE bonds only win if you hold them for exactly 20 years, when Treasury adjusts them to double your purchase price, which works out to about 3.53% a year.

2. Can I buy both I bonds and EE bonds in the same year?

Yes. The $10,000 annual limits are separate, so one person can buy $10,000 of I bonds and $10,000 of EE bonds in the same calendar year. A married couple with two TreasuryDirect accounts can therefore place up to $40,000 a year across the two series.

3. What happens if I cash an EE bond before 20 years?

You earn only the stated fixed rate, currently 2.40% a year, and you lose the doubling adjustment entirely. If you cash it before five years you also give up the last three months of interest. There is no partial credit for holding 15 or 19 years.

4. Do I pay state tax on I bonds or EE bonds?

No. Interest on both Series I and Series EE savings bonds is exempt from state and local income tax. Federal income tax still applies, but it is deferred until you cash the bond or it stops earning interest at 30 years, so you have some control over the year it lands.

5. How long do I have to hold a savings bond before I can sell?

Twelve months, for both series. Between month 12 and year five you can redeem any time but forfeit the last three months of interest. After five years there is no penalty, and both bonds keep earning until they reach 30 years.
