Can you lose money in a fixed index annuity?

Not from a falling index. Yes, from charges, early withdrawals and the insurer itself

The short answer is two answers, and the order matters. A falling index cannot reduce your account value. That is exactly what the 0% floor does: in a year the index drops, the interest credited to your contract is zero rather than negative, and interest credited in earlier years is not clawed back to pay for it. That protection is real, it is the reason these contracts exist, and it is what most people are asking about.

What the floor covers is the index. It does not cover anything else, and money can still leave the account by other routes: charges deducted every year, surrender charges if you take money out early, inflation, and the insurer's own ability to pay. None of those has anything to do with the market, which is why a floor cannot stop them.

This page sets out each one, in the words of a regulator rather than ours, because we are an insurance agency that sells these products and you should weigh what we say accordingly.

What a regulator and a carrier both say

None of this is a minority view, and it is worth seeing both halves stated by somebody other than us. Guardian, a carrier that sells these contracts, puts the protection plainly on its own fixed index annuity page: “If the index falls, your principal is protected from losses.” The same page is equally plain about the other half: “It's possible to lose money with a fixed index annuity, but if you do, it's likely because you have withdrawn too much or too early, and as a result, paid withdrawal charges and penalty taxes.”

FINRA, the regulator for securities firms, puts the same product this way: “After paying surrender charges, depending on the returns and amounts forfeited, an investor may lose some of the principal invested by surrendering an indexed annuity too soon.” Fidelity, on a page updated in September 2025, states it more briefly still: “You can lose principal in a fixed indexed annuity due to surrender charges if you withdraw assets before the surrender period is up.”

Both statements and the floor are true at once. The floor governs how interest is credited. It has nothing to do with what leaving early costs, what the contract charges you along the way, or what the insurer is allowed to change later.

Where money can actually leave the account

1. Surrender charges. The main one. FINRA describes withdrawing principal “during a certain time period, usually within the first six to 10 years after the annuity was purchased,” as triggering charges that can also carry tax consequences. This is not a penalty for doing something wrong. It is the ordinary cost of ending the contract early, and it is why money you might need should not be in one.
2. Forfeited interest you had already earned. Less well known and worth asking about directly. In FINRA's words, “under some contracts, if withdrawals are taken, amounts already credited from returns will be forfeited.” A good index year can be undone by a withdrawal in a later one, depending on what your contract says.
3. Charges taken from the value each year. Optional riders, income riders in particular, carry an annual charge deducted from the contract value whether or not the index did anything. In a flat year, a contract with a rider charge can credit zero interest and still be worth less at the end of the year than at the start. Ask for that charge as a dollar figure, annually, before you sign.
4. Terms the insurer can change at renewal. The one almost nobody discloses. FINRA again: “Some EIA [equity-indexed annuity] contracts allow the issuer to change the fees, participation rates and interest caps from time to time, which could adversely affect your return.” The cap you were shown at the sale is generally the current cap, not a permanent one. Contracts set a floor under those terms, so ask what the contractual minimum cap and participation rate are, not just today's.

There is a fifth effect that is not a loss on any statement but is a loss in the shop. A year credited at zero is zero in nominal dollars and a real reduction in what those dollars buy. Over a long surrender period that arithmetic is part of the trade, and it belongs in the comparison.

One more thing to ask about by name: whether a market value adjustment applies to your contract, and in what circumstances. It is a common feature and its effect on an early withdrawal should be explained to you in writing.

What California gives you, specifically

State law here is stronger than the national baseline, and two provisions are worth knowing before any appointment.

If the insurance company fails

The promise behind every one of these contracts is the insurer's. As FINRA states, an annuity “is only guaranteed as long as the insurance company issuing it remains in business.” California has a safety net, the California Life and Health Insurance Guarantee Association, and it is limited. Its own published answers put annuity cover at 80% of the present value up to a maximum of $250,000, within an overall $300,000 cap per individual.

We are raising it here to explain a limit, and to say something that is easy to miss. In the association's own words, insurers and agents “are prohibited by state law from using the existence of the Guarantee Association to sell, solicit or induce the purchase of any form of insurance.” If anyone ever offers it to you as a reason the purchase is safe, that is a reason to end the meeting. The right response to carrier risk is to check the carrier, which our evaluation guide walks through.

Five questions that settle it

1. Show me the surrender charge schedule year by year, in the contract, not the brochure, and tell me whether a market value adjustment applies.
2. How much can I take out each year without a charge, and does a withdrawal forfeit interest already credited?
3. What is today's cap or participation rate, and what is the contractual minimum the insurer could reduce it to at renewal? What has this carrier actually renewed at on existing contracts?
4. What does each rider cost per year in dollars, and what happens to my value in a year the index returns nothing?
5. What is the issuing insurer's financial strength rating, and where can I look it up myself?

If a question cannot be answered from the contract in front of you, the answer is not yet available and nothing needs signing today.

Where this leaves the product

A fixed index annuity is not a scam and it is not a savings account. It is a contract that trades access to a portion of your money, for a set number of years, for interest that is limited on the upside and floored at zero on the downside, backed by one company's ability to pay. Whether that is worth doing depends on whether you have an income gap and on how much of your savings would still be reachable afterwards.

Our fixed indexed annuity page explains the crediting mechanics in detail, our annuities overview puts the disadvantages first, and our retirement income calculator works out whether there is a gap to fill at all. If there is not, there is nothing here you need.
