The core difference: how your money grows

A fixed annuity pays you a may provide interest rate set when you buy it. That rate stays the same for the entire contract period — typically three to ten years. If the insurance company promises 3 percent annually, you receive 3 percent every year, regardless of what happens in the stock market or the broader economy.

An indexed annuity ties your growth to a stock market index — usually the S&P 500 — but with a cap and a floor. Your money cannot lose value if the market falls (the floor protects you), but your gains are limited by a cap that the insurance company sets. If the S&P 500 rises 12 percent in a year but your cap is 8 percent, you earn 8 percent, not 12 percent.

The trade-off is straightforward: fixed annuities offer certainty and simplicity. Indexed annuities offer the possibility of higher returns when markets perform well, but you never capture the full market gain.

Key Takeaways

  • Fixed annuities may provide a specific interest rate for the life of the contract, while indexed annuities link returns to a stock market index with a built-in cap on gains.
  • Indexed annuities protect you from market losses but limit your upside; fixed annuities eliminate both downside risk and the possibility of market-beating returns.
  • The fees and surrender charges differ between the two: indexed annuities typically cost more because the insurance company bears the cost of the market protection.
  • Your choice depends on whether you prioritize predictability and simplicity (fixed) or the possibility of higher income in strong market years (indexed).

How the cap and floor work in an indexed annuity

When you purchase an indexed annuity, the insurance company sets three numbers: the cap, the floor, and the participation rate. The cap is the maximum return you can earn in any given year — commonly between 6 and 10 percent, though this varies by product and market conditions. The floor is usually zero, meaning your account value cannot drop below what you put in, even if the index falls sharply.

The participation rate determines what percentage of the index's gain you actually receive. If the participation rate is 80 percent and the index rises 10 percent, you earn 8 percent (before the cap is applied). Some indexed annuities use a spread or margin instead — the insurance company subtracts a fixed percentage from the index's gain before calculating your return.

These terms reset periodically, often annually or at the end of a multi-year term. An indexed annuity that offered a 9 percent cap one year might offer 6 percent the next year, depending on interest rates and the insurance company's pricing.

Fees and costs: where the differences matter

Fixed annuities typically have lower internal costs because the insurance company's obligation is straightforward: pay the stated rate. You may pay a surrender charge if you withdraw money before the contract ends, but ongoing fees are usually minimal or transparent.

Indexed annuities cost more to administer because the insurance company must hedge its risk — it buys options on the stock market index to protect itself against large gains that would exceed the cap. Those hedging costs are built into the product, which is why indexed annuities often have higher internal expenses than fixed annuities, even if you do not see a separate line item labeled "fee."

Both types typically charge a surrender charge if you withdraw more than a small percentage (often 10 percent annually) before the contract matures. The surrender charge period can last five to fifteen years. After that period ends, you can usually withdraw your money without penalty.

Liquidity and access to your money

Both fixed and indexed annuities restrict your access to your principal during the surrender charge period. If you need the money before that period ends, you pay a penalty — often 5 to 10 percent of the withdrawal amount in the early years, declining as the contract ages.

Some indexed annuities allow you to withdraw a small percentage (often 10 percent) each year without penalty, even during the surrender charge period. Fixed annuities may offer the same feature, but it depends on the specific contract. Read the contract language carefully, because the rules vary widely.

After the surrender charge period expires, both types allow you to withdraw your full balance without penalty, though you may owe income tax on the gains. Some people use this point to move their money to a different annuity or investment vehicle.

Income options and payout structures

Both fixed and indexed annuities can be converted into a stream of income — a process called annuitization. Once you annuitize, the insurance company calculates a monthly or annual payment based on your age, the account balance, and current interest rates. That payment continues for life (or for a set period, depending on the option you choose).

Fixed annuities make this calculation straightforward because the insurer knows exactly what interest rate to use. Indexed annuities use a different approach: the insurance company typically applies a fixed interest rate to your accumulated balance, not the indexed rate. This means the income calculation is more conservative than it might appear.

Some indexed annuities offer a rider (an add-on feature) that guarantees a minimum income level, even if your account balance falls. These riders cost extra but provide peace of mind. Fixed annuities do not need such riders because the income is already may provide by the base contract.

Tax treatment and reporting

Both fixed and indexed annuities are tax-deferred, meaning you do not pay income tax on the gains until you withdraw the money. This applies whether you buy the annuity inside a retirement account (like an IRA) or outside one.

When you do withdraw or annuitize, the gains are taxed as ordinary income, not as capital gains. This is true for both types. The insurance company will send you a 1099-R form reporting the taxable portion of any distribution.

If you own the annuity outside a retirement account and you die before annuitizing, your beneficiary receives the account value, and the gains are taxed as ordinary income to them in the year of distribution. The tax treatment is the same for fixed and indexed annuities.

Which type makes sense for different situations

Choose a fixed annuity if you want predictability and simplicity. You know exactly what you will earn each year. This works well if you are near or in retirement and you want to replace a pension or create a may provide income floor. Fixed annuities are also easier to understand and explain to a financial advisor or family member.

Choose an indexed annuity if you have a longer time horizon (at least ten years) and you can tolerate the complexity of caps and participation rates. Indexed annuities make sense if you believe the stock market will perform reasonably well over time but you want downside protection. They also work if you want the possibility of income that keeps pace with inflation, since market-linked returns can exceed fixed rates in strong years.

Neither type is inherently better — the right choice depends on your age, how long you plan to keep the money invested, how much certainty you need, and whether you are comfortable with the indexed annuity's moving parts.

Frequently Asked Questions

Can I move money from a fixed annuity to an indexed annuity?

Yes, through a process called a 1035 exchange, which allows you to transfer the balance from one annuity to another without triggering when ready taxes. However, you will start a new surrender charge period with the new contract, and the terms (cap, participation rate, fees) will be different. Consult a tax professional before doing this, because the rules are strict.

What happens to my indexed annuity if the stock market crashes?

Your account value does not fall. The floor (usually zero) protects you, so you keep what you have contributed plus any gains earned in prior years. However, you earn zero percent return that year — you do not earn negative returns, but you also do not participate in any recovery until the next measurement period begins.

Is the may provide rate on a fixed annuity really may provide?

Yes, for the contract period. The insurance company is legally obligated to pay it. However, that may provide is only as strong as the insurance company itself. If the company becomes insolvent, your state's insurance guaranty fund steps in, but coverage limits explore (usually $250,000 per contract per insurer). Buy from well-rated insurers to minimize this risk.

Do I have to annuitize an indexed annuity, or can I just withdraw the money?

You can do either. Annuitization converts your balance into a may provide income stream, but it is optional. You can also take withdrawals as you need them, or withdraw the full balance after the surrender charge period ends. The choice is yours, and it should depend on whether you want may provide income or flexibility.

Which type has better returns over time?

That depends entirely on stock market performance. In years when the S&P 500 rises more than the indexed annuity's cap, the fixed annuity may outperform. In years when the market falls, the indexed annuity protects you while the fixed annuity continues paying its set rate. Over very long periods, indexed annuities have historically kept pace with or slightly exceeded fixed annuities, but past performance does not predict future results.
