What is a fixed indexed annuity?
Published · Updated
Short answer: A fixed indexed annuity (FIA) is an insurance contract that credits interest linked to a market index, such as the S&P 500, without investing your money in the market. When the index rises you get part of the gain, within a cap, participation rate or spread, and when it falls your index credit is 0%. The trade is a surrender period and limited upside, and guarantees depend on the issuing insurer's claims-paying ability, not the FDIC.

How a fixed indexed annuity works
So how it works is pretty simple on paper. You put money into the contract, usually as one lump sum. At the end of each crediting period, often one year, the insurer looks at how the index did and credits interest to your account value. The insurer is basically saying, "Leave this with us, and we'll give you part of the index's gain. In a down year, we credit you zero."
You're mirroring the index. Your money isn't invested in the market, so you don't own shares and you don't take the index's losses.
Example: the index rises 12% for the year and your strategy has an 8% cap, so you're credited 8%. The next year the index falls 15%, and your index credit for that year is 0%.
FIAs are a big market. U.S. fixed indexed annuity sales were $30.6 billion in the second quarter of 2026, according to LIMRA's U.S. Individual Annuity Sales Survey (released September 8, 2026).
The limits on your upside: cap, participation rate and spread
There has to be something in it for the insurance company, so your share of the gain is limited. Each strategy uses one or more of these:
- A cap is the most interest an FIA can credit you for the period. Example: with an 8% cap, if the index rises 12% you're credited 8%. If it rises 5%, you get 5%.
- A participation rate is the share of the index gain used to figure your credit. Example: at 50% participation, an index gain of 10% gets you a 5% credit.
- A spread is a percentage taken off the index gain before interest is credited. Example: a 2% spread and a 7% index gain leave you a 5% credit. If the index is up 1.5%, you're credited 0 for that period.
Some strategies combine them, so ask for the full calculation. Example: 80% participation with a 6% cap, and the index is up 10%. 80% of 10% is 8%, and the cap holds it to 6%.
Two more things surprise people. First, these limits can change at the reset dates in the contract, within minimums written into it. Example: an 8% cap this year could reset to 6% next year, and never below the contract's minimum cap (for example, 3%). Second, most strategies track a price index, which leaves out dividends. The SEC's Investor Bulletin on indexed annuities (July 31, 2020, checked October 22, 2026) notes that dividends are usually excluded when the gain is figured.
What the 0% floor covers
In an FIA we say zero is your hero: a bad index year is a zero, not a loss. The floor covers index crediting only. Fees, withdrawals, surrender charges and any applicable market value adjustment can still reduce value. Our 0% floor guide walks through each one with examples.
Surrender charges and getting money out
An FIA is built for money you can leave alone for a while. Most contracts let you take out a set amount each year without a charge. Above that, a surrender charge applies during the surrender period. The SEC's Investor Bulletin says surrender periods typically last six to ten years, or even longer.
Example: 10% free withdrawal a year and a 7% surrender charge in year 1. On $100,000, you take out $30,000 in year 1. $20,000 is over the free amount, and 7% of that is $1,400.
Taxes matter too. The same bulletin notes that taking money from a tax-deferred indexed annuity before age 59½ may mean a 10% federal tax penalty. Ask for the year-by-year surrender schedule, the free-withdrawal amount, whether there's a market value adjustment, and whether there are waivers (for example, nursing home care or terminal illness).
Optional income riders
Many FIAs offer an optional lifetime income rider, which usually has an annual fee. Think of it as setting up your own personal pension. If you add one, your statement may show two numbers: the account value and a benefit base.
Example: $100,000 account value, $120,000 benefit base. You can't withdraw the $120,000. The benefit base is only used to figure income.
A lifetime withdrawal benefit may continue payments after the contract value reaches zero, provided its conditions are met. Ask whether the income you're shown is net of the rider fee.

How an FIA compares with a MYGA and a CD
People often look at these three side by side. The FIA comes first because it's the product this page is about.
| Fixed indexed annuity | MYGA | CD | |
|---|---|---|---|
| What it is | An insurance contract | An insurance contract | A deposit at a bank |
| How interest is set | Linked to a market index, within a cap, participation rate or spread, with a 0% floor on index crediting | A set rate for a set term | A fixed rate for the term |
| Getting money out early | Free-withdrawal amount each year, surrender charges above it during the surrender period | Free-withdrawal amount, surrender charges above it | Early-withdrawal penalty |
| Backing | Not FDIC insured. Guarantees depend on the issuing insurer's claims-paying ability | Same as an FIA | FDIC insured within limits |
Terms vary by contract and bank. For fixed-rate comparisons, see this week's 5-year MYGA rates and MYGA vs CD.
Who an FIA tends to fit
An FIA tends to fit people who want some growth tied to the market without index losses, and who can leave the money in place through the surrender period. It's usually a poor fit for money you may need soon. Money for the car, the roof or the trip you've been putting off is better kept somewhere you can reach it. If a pitch sounds too good, ask whoever recommends it how they're paid. A good advisor will answer that plainly.
Questions worth asking before you buy
- What's the cap, participation rate or spread on each strategy, and how can they change after year one?
- How long is the surrender period, and what's the charge in each year?
- How much can I take out each year without a charge?
- Are there rider fees, and is the income I'm shown net of them?
- What's the issuing insurer's financial strength rating?
Plain-English FAQ
Is my money invested in the stock market?
No. An FIA credits interest linked to a market index. You're mirroring the index, and your money isn't invested in the market, so a falling index means a 0% index credit for that period instead of a loss.
Can you lose money in a fixed indexed annuity?
Not from index drops, because of the 0% floor. The floor covers index crediting only. Fees, withdrawals, surrender charges and any applicable market value adjustment can still reduce value, and withdrawals before age 59½ may face a 10% federal tax penalty.
How is a fixed indexed annuity different from a variable annuity?
A variable annuity puts your money in funds, with no built-in limit on losses. An FIA credits interest linked to an index and its index credit can't go below 0%. A registered index-linked annuity (RILA) sits in between and can lose money, according to the SEC's Investor.gov annuities page.
Does a fixed indexed annuity have fees?
Many FIAs have no separate yearly fee on the base contract. The cost is built in through crediting limits like caps, participation rates and spreads, plus surrender charges if you leave early. Optional riders, such as a lifetime income rider, usually carry an annual fee.
How long is my money tied up in an FIA?
For the surrender period in your contract. The SEC's Investor Bulletin on indexed annuities says surrender periods typically last six to ten years, or even longer. Most contracts allow a free-withdrawal amount each year without a charge.
Is a fixed indexed annuity FDIC insured?
No. Annuities aren't FDIC insured. Guarantees depend on the issuing insurer's claims-paying ability, so ask for the insurer's financial strength rating.
Can I hold an FIA inside an IRA?
Yes. Think of the IRA as the box and the FIA as what's inside it. You can hold an FIA inside an IRA (qualified), or buy one with money that's already been taxed (non-qualified), and the tax rules differ. An annuity inside an IRA doesn't add any extra tax deferral, so ask how it fits your plan. Not tax advice.
