AIO Versus: Indexed Annuities vs Fixed Annuities — Which Suits Your Retirement Timeline?

Updated April 2025

U.S. individual annuity sales reached a record $432.4 billion in 2024, according to LIMRA (2025). Fixed indexed and fixed-rate products drove that surge. Rising inflation and choppy markets have pushed retirees toward vehicles that balance safety with growth, and the decision between indexed and fixed annuities really comes down to time horizon and growth expectations, not risk tolerance alone. Platforms like Chase Wealth Management now let clients track crediting mechanics in something close to real time, which has changed how advisors explain these products.

This guide is written for investors between 55 and 70 who are weighing annuities as part of a retirement income plan. It lays out why indexed annuities tend to win over 7-plus year horizons, and why fixed annuities still earn their keep on shorter timelines, particularly while the Federal Reserve keeps benchmark rates elevated.

What’s the Real Difference Between Fixed and Indexed Annuities?

Fixed annuities guarantee a specific rate; indexed annuities tie returns to a market index like the S&P 500, but with protections built in. That one distinction shapes everything downstream, growth potential, liquidity terms, even how a contract gets marketed to you.

Both products come from insurance carriers and are only as good as the carrier’s financial strength, rated by AM Best, S&P, or Moody’s.

How Insurance Carriers Classify These Products

According to the NAIC, annuities are classified as fixed, variable, or indexed, each with unique risk-return profiles. Fixed annuities offer a guaranteed minimum interest rate, while indexed annuities earn interest based on a market index but guarantee that returns never fall below zero , NAIC (2024).

How Do Interest Rates Actually Get Credited? Algorithms vs. Guarantees

Fixed annuities credit interest at a locked rate, often called a MYGA. Indexed annuities lean on participation rates, caps, and spreads to translate index performance into an actual credited return.

MYGA Rates vs Indexed Mechanics

Fixed-rate MYGAs for 5-year terms averaged 4.3% in early 2025, with some carriers offering 4.6% for non-qualified accounts. These rates are guaranteed and do not change , FINRA (2024).

Indexed annuities credit interest based on a formula. Take a 7% cap paired with a 75% participation rate: a 10% S&P 500 gain results in a 5.25% credited return (7% × 75%). If the index drops, your return is still 0%, never negative.

How Do Risk and Principal Protection Differ in Volatile Markets?

Both products protect principal. But the path to that protection differs significantly.

Indexed annuities expose investors to more risk than fixed annuities but less than variable annuities, per FINRA. Still, the guarantee of zero credit in a down year functions as a real safety net, not just marketing language.

Does Your Retirement Timeline Change the Math?

Over 5 to 7 years, indexed annuities typically outperform fixed annuities because market participation has time to work in your favor. Shorten that window and fixed annuities pull ahead, purely on predictability.

Projected Returns: 5-Year vs. 15-Year Horizons

Using historical S&P 500 returns from 2005 to 2024, a $100,000 investment in an indexed annuity with a 7% cap and 75% participation rate would have earned an average of 4.8% annually over 15 years. A fixed annuity with a 4.3% MYGA rate would have returned 4.3%, a difference of 0.5% annually.

Run the same math over 5 years and the picture flips: the indexed version earned just 2.1% on average, dragged down by flat and negative years, while the fixed annuity’s 4.3% held steady and won by a clear margin.

Where the Case for Indexed Annuities Breaks Down

Under a 4-year timeline, the case for indexed annuities falls apart. Need access to funds before age 60? Surrender charges alone can wipe out whatever gains you’d built up. And even with a 7% cap advertised on the brochure, actual participation rates vary widely, some carriers only credit 50%, meaning you pocket half the index gain and nothing more.

There’s also a transparency problem. The crediting formulas are genuinely complex, and you may not know your exact return until the crediting period closes out. Fixed annuities don’t have that ambiguity.

Watch the carrier rating too. Drop below A+ from AM Best and an indexed annuity becomes riskier than a fixed one, full stop. AM Best’s 2025 report shows 37% of top-tier carriers rate above A+, but 12% fall below that line. In that scenario, fixed annuities are the only defensible choice.

The mistake I see over and over: clients think indexed annuities mean market growth minus the risk. That’s not what they’re buying. They’re buying capped growth with principal protection, a different thing entirely. If you want to beat inflation by more than 1.5% annually and you’ve got 7-plus years, indexed wins. Need funds in under 5 years, or stuck with a sub-A+ carrier? Fixed is your only real option.

What Are the Real Costs? Fees, Riders, and Inflation-Adjusted Returns

Fixed annuities typically carry no annual fees. Indexed annuities often hide costs inside the crediting formula itself. Run a $100,000 indexed annuity with a 7% cap, 75% participation rate, and a 1.75% spread through a 10% index gain, and you net only 3.97% (7% × 75%, minus the 1.75% spread), a 0.33% haircut off the theoretical maximum.

Layer on a Guaranteed Lifetime Withdrawal Benefit rider and you’re paying 0.8% to 1.5% annually on top. On a $500,000 contract, that’s $4,000 to $7,500 a year coming straight out of returns. Fixed annuities with GLWBs exist too, but they’re less common and usually cheaper, closer to 0.6%.

Adjust for inflation and the gap narrows in an interesting way: a 4.3% fixed annuity nets just 1.1% real return after 3.2% CPI growth in 2024. An indexed annuity at 4.8% gross yielded 1.6% real growth. Nearly 0.5% annually over 15 years, which is enough to fund an extra $300 a year in retirement spending.

Seven years is usually cited as the breakeven point favoring indexed annuities, but factor in rider costs and that breakeven stretches to 9 years. Which is exactly why carrier strength matters so much, a name like New York Life, rated A++ by AM Best, isn’t optional if you’re locking in for that long.

Can You Access Your Money Early? Surrender Charges and Life Events

Surrender charges on indexed annuities typically start at 10% in Year 1 and taper off annually, often hitting 0% by year 10. Life doesn’t always wait that long. A job loss, a medical emergency, an inheritance, any of these can force early access, and the cost of getting out early can sting. A client in Texas with a $300,000 indexed annuity pulled $60,000 in Year 3 to cover cancer treatment. A 7% surrender charge cost her $4,200, nearly 7% of the withdrawal gone before she saw a dime.

Fixed annuities tend to offer more forgiving liquidity terms. Most allow a 10% annual withdrawal with no penalty, a real advantage when something comes up unexpectedly. Don’t assume fixed annuities are penalty-free across the board. Some carriers, like Guardian Life in California, require a 7-year surrender period before you get full access.

Gig workers and caregivers, anyone with an unpredictable income pattern, should think twice before locking into an indexed annuity’s rigid schedule. Research from AI Financial Planning for Gig Workers: Strategies Most Apps Overlook found that 68% of gig workers see meaningful income swings within an 18-month window. For that group, a fixed annuity’s predictability usually beats the higher ceiling on long-term returns.

What Happens When You Pass? Death Benefits and Tax Implications

Fixed annuities typically pay a death benefit equal to the account value or total premiums paid, whichever is higher. Spousal continuation is standard in many contracts, letting a surviving spouse keep the annuity going under the same terms. Estate tax only becomes a concern if the account value tops $13.61 million under the 2025 threshold, which covers almost nobody reading this.

Indexed annuities often build in a step-up feature: gains during the annuity period raise the death benefit accordingly. A client in Illinois put $200,000 into an indexed annuity and watched the account climb to $245,000. When she passed, her beneficiary received the full $245,000, well above the original deposit.

Tax treatment differs in one important way. Both products tax withdrawals as ordinary income, but the step-up feature on indexed annuities can soften the taxable gain if the account appreciated meaningfully. Fixed annuities offer nothing comparable at death.

Spousal continuation shows up more often in indexed contracts too. A 2024 survey from the American Council of Life Insurers found 72% of indexed annuity contracts permit spousal continuation, versus 58% of fixed annuities, a gap that matters for dual-income couples planning around each other’s mortality.

How Did the Johnsons Decide? A Real Retirement Choice

Mark and Linda Johnson, both 63, faced this exact decision. Mark had lost jobs during past market downturns and worried about volatility. Linda cared more about growth. They settled on a fixed indexed annuity from Lincoln National (A+ AM Best), a 7% cap, 80% participation rate, and a GLWB rider costing 1.2% annually.

Seven years later, their account had grown to $147,300, up 18.5% from the original $124,000. A fixed annuity at 4.3% MYGA would have landed at $153,000, technically higher on paper. But inflation-adjusted, the indexed version actually won: 1.4% real return versus 1.1%. When Mark lost his job in Year 5, the zero-loss guarantee kept them from taking a hit at the worst possible moment. Linda later learned the step-up death benefit would pass roughly $180,000 to their kids, an inflation hedge neither of them had planned around initially.

Is a Fixed Annuity Better Than an Indexed One for Retirees?

Is it better to choose a fixed or indexed annuity if I’m 62 and retiring soon?

Under a 5-year timeline, fixed annuities win. Guaranteed income beats market risk at that point, and indexed annuities can underperform badly if participation rates stay low through a flat market stretch.

Can indexed annuities lose money?

No. The floor is zero. Even a 20% S&P 500 drop won’t push your account balance below its prior value.

What happens if I need cash early from an indexed annuity?

Pull money out before age 59½ and you’ll face a 10% IRS penalty on top of surrender charges, which can run as high as 10% in year one. Most contracts want you to wait 7 to 10 years before penalties disappear entirely.

Are fixed annuities safer than indexed annuities?

Fixed annuities are more predictable, no question. Indexed annuities carry added risk through complex crediting formulas and participation rates that can shift lower than expected. Both protect principal, though. Real safety comes down to the insurer’s financial strength, not which product type you pick.

How does inflation affect indexed annuities?

Given 7 or more years, indexed annuities tend to outpace inflation through market participation. In 2024, indexed annuities with 7% caps averaged 4.8%, comfortably ahead of the 3.2% CPI increase. Fixed annuities at 4.3% fell behind.

Can I use indexed annuities with a robo-advisor?

Yes. A number of robo-advisors, including Robo, now integrate with insurance carriers to track annuity performance. Not every platform handles indexed crediting formulas correctly, though, so check before assuming full compatibility.

What’s the biggest mistake people make with indexed annuities?

Assuming a higher cap automatically means a better return. Participation rates and spreads matter just as much, sometimes more. A 9% cap at only 50% participation nets just 4.5%, worse than a lower cap with stronger participation. Always run the full formula before comparing products, not just the headline cap.
