Should You Choose a Fixed Index Annuity or a RILA?
A fixed index annuity (FIA) protects 100% of your principal from market losses. A registered index-linked annuity (RILA) does not. RILAs let you absorb a portion of market losses in exchange for higher growth potential, including higher caps and sometimes uncapped participation.
If you cannot tolerate any loss of principal, an FIA is the right answer. If you are willing to accept some downside risk for the chance of meaningfully higher returns, a RILA is worth a serious look. For most retirees with $100,000 to $500,000 to invest, the choice comes down to a single question: how much pain can your portfolio actually handle in a bad year?
What Is a Fixed Index Annuity?
A fixed index annuity is an insurance contract that credits interest based on the performance of a market index, like the S&P 500, while guaranteeing that your principal will never decline due to a market drop. In a year when the index falls 30%, your account value stays flat. In a year when the index rises 25%, you earn a portion of that gain, capped at a number set by the carrier.
FIAs are regulated as insurance products by state insurance departments, not as securities. Agents who sell them need a state insurance license. You do not own the underlying index. The carrier uses options strategies to credit you a portion of the index return based on a formula spelled out in your contract.
The trade-off is clear. You give up some upside (the cap or participation rate) in exchange for a hard floor of zero. In a year when the S&P 500 returns 18% and your FIA has a 6% cap, you get 6%. In a year when the S&P 500 returns -22%, you get 0%. Over a full market cycle, that floor matters more than most people expect.

What Is a Registered Index-Linked Annuity (RILA)?
A registered index-linked annuity, often called a buffer annuity or structured annuity, is a hybrid between a variable annuity and a fixed index annuity. Like an FIA, it credits interest based on a market index. Unlike an FIA, it does not protect 100% of your principal. You agree to absorb some portion of market losses in exchange for higher growth potential.
RILAs use one of two protection structures:
- Buffer: The insurer absorbs the first X% of losses. A 10% buffer means the carrier eats the first 10% of an index decline. If the index drops 15%, you lose 5% (the amount above the buffer). If it drops 8%, you lose nothing.
- Floor: Your loss is capped at a fixed amount. A -10% floor means the worst you can lose in a given crediting period is 10%, no matter how far the index falls.
In exchange for accepting some downside, RILA caps are typically much higher than FIA caps. It is not unusual to see RILA caps of 15% to 25% on the same S&P 500 strategy where an FIA might cap at 5% to 7%.
RILAs are registered as securities with the SEC. Agents who sell them need a Series 6 or Series 7 license in addition to a state insurance license, and buyers receive a prospectus rather than a simple disclosure document.
FIA vs RILA: Side-by-Side Comparison
| Feature | Fixed Index Annuity | RILA (Buffer Annuity) |
|---|---|---|
| Principal Protection | 100% protected from market loss | Partial; buffer or floor structure |
| Typical Cap Rate (S&P 500) | 5% to 8% | 15% to 25% |
| Downside Risk | None (zero floor) | Possible; 10% buffer means losses begin at -10% |
| Regulation | State insurance department only | SEC registered (issued with prospectus) |
| Agent License Required | State insurance license | Insurance license + Series 6 or 7 |
| Surrender Period | Typically 5 to 10 years | Typically 5 to 7 years |
| Income Rider Available | Yes, on most products | Available on some products, less common |
| Tax Treatment | Tax-deferred growth; ordinary income on withdrawal | Same: tax-deferred growth; ordinary income on withdrawal |
| Best For | Conservative buyers who want zero downside | Buyers willing to accept moderate downside for higher upside |
The Real-World Trade-Off: A Worked Example
Margaret, age 64, has $200,000 to invest from a 401(k) rollover. She is comparing a 6-year FIA with a 6% annual cap on an S&P 500 point-to-point strategy against a 6-year RILA with a 10% buffer and an 18% annual cap on the same index. Both products use the same crediting period, both are issued by A-rated carriers, and both let her start with $200,000.
Here is how each performs in three different market scenarios:
| Year 1 S&P 500 Return | FIA Account Value | RILA Account Value |
|---|---|---|
| +22% (strong year) | $212,000 (capped at 6%) | $236,000 (capped at 18%) |
| +5% (modest year) | $210,000 (full 5% credited) | $210,000 (full 5% credited) |
| -25% (bad year, like 2008) | $200,000 (zero floor) | $170,000 (10% buffer absorbs first 10%; Margaret loses the next 15%) |
The RILA wins decisively in a strong market and ties in a flat year. The FIA wins decisively in a crash. Over a full market cycle of 6 to 10 years, the right choice depends on how often markets crash during your specific holding period. Nobody knows that in advance, which is why the question really is about risk tolerance, not return forecasting.
How Are They Taxed?
Both FIAs and RILAs are tax-deferred annuity contracts, so the tax treatment is essentially identical:
- Non-qualified (after-tax money): Gains grow tax-deferred. Withdrawals are taxed as ordinary income on the gain portion only, with a 10% IRS penalty if you withdraw before age 59½.
- Qualified (IRA or 401(k) rollover): The entire withdrawal is taxed as ordinary income. RMDs apply at age 73.
One important note: holding either an FIA or a RILA inside an IRA does not give you any extra tax benefit. The IRA already provides tax deferral. The reason to use either product inside an IRA is for the principal protection (FIA) or the buffered structure (RILA), not the tax wrapper.
Liquidity: Surrender Charges and Free Withdrawals
FIAs and RILAs have very similar liquidity profiles. Both products typically allow penalty-free withdrawals of up to 10% of the account value each year. Withdrawals beyond that trigger a surrender charge that starts high (typically 7% to 9%) in year one and declines to zero by the end of the surrender period.
RILA surrender periods tend to be slightly shorter than FIA surrender periods (5 to 7 years versus 5 to 10 years). If you may need access to a large lump sum before then, neither product is a good fit. Both products generally waive surrender charges in cases of nursing home confinement, terminal illness, or required minimum distributions for qualified accounts.
Carrier Strength and Safety
Both FIAs and RILAs are insurance contracts, which means your guarantees are only as strong as the carrier issuing the contract. Always check the carrier’s Comdex score and AM Best rating before purchasing. Look for carriers rated A- or better.
If a carrier becomes insolvent, your state’s Life and Health Insurance Guaranty Association steps in to protect annuity contracts up to a coverage limit (typically $100,000 to $250,000 per carrier per contract owner, depending on the state). If you are placing more than the guaranty limit into either product, consider splitting the premium across two A-rated carriers.
Who Should Choose a Fixed Index Annuity?
An FIA is the right choice if:
- Losing principal in a market downturn would seriously damage your retirement plan
- You sleep better knowing your account value cannot go down due to market action
- You are within 5 to 10 years of needing the money for retirement income
- You want to protect a specific dollar amount (like a retirement nest egg or inheritance) from market risk
- You may want to add a lifetime income rider for future guaranteed income
Who Should Choose a RILA?
A RILA is the right choice if:
- You can tolerate a moderate loss in a bad year if it gives you meaningfully higher upside
- You are 10 or more years from needing the money
- You have other sources of guaranteed income (Social Security, pension, MYGAs) and can take some risk on this allocation
- You want index participation rates closer to what direct market investing would offer, without going fully variable
- You understand and are comfortable with how buffers and floors work
Frequently Asked Questions
Can you lose money in a fixed index annuity?
No, not from market losses. An FIA’s account value cannot decline due to a drop in the underlying index. You can lose money in an FIA only by surrendering early (and paying a surrender charge), withdrawing more than the free withdrawal amount during the surrender period, or by paying optional rider fees that exceed your credited interest in a flat year.
Can you lose money in a RILA?
Yes. RILAs explicitly accept some market risk in exchange for higher growth potential. With a 10% buffer, you absorb any losses beyond the first 10%. With a -10% floor, you absorb the first 10% of losses but cannot lose more than that. The amount you can lose depends on the specific protection structure you choose.
Are RILAs riskier than variable annuities?
No. RILAs sit between FIAs and variable annuities on the risk spectrum. Variable annuities have no downside protection at all (your subaccount balance can fall as far as the market falls). RILAs limit your downside through buffers or floors. FIAs eliminate downside entirely.
Why are RILA caps so much higher than FIA caps?
The carrier uses the buffer or floor to reduce its hedging cost. By making you absorb some losses, the carrier has more option budget to spend on upside, which it passes through as higher caps and participation rates. There is no free lunch – the higher cap is exactly compensation for the downside risk you accept.
Can I switch from a RILA to an FIA later?
You can use a 1035 exchange to move from a RILA to an FIA (or vice versa) without triggering taxes, as long as both are non-qualified annuities. Surrender charges may still apply on the original contract if you have not completed the surrender period. Always run the math before doing a 1035 exchange.
Which carriers offer both FIAs and RILAs?
Many of the largest annuity carriers issue both product types, including Allianz, Athene, Equitable, Brighthouse, Lincoln Financial, Prudential, and Corebridge. This makes side-by-side comparison straightforward when you are working with a single insurer.
The Bottom Line
The choice between an FIA and a RILA is fundamentally a question about loss tolerance, not return optimization. If you can confidently say “I can absorb a 10% loss in a bad year,” then a RILA’s higher caps will likely outperform an FIA over a full market cycle. If that statement makes your stomach turn, an FIA is the right product for your money, full stop.
For most retirees we work with at My Annuity Store, the FIA wins because the buyer is using the money to backstop their retirement income, not to speculate. If you have a separate growth bucket already covering market upside, a RILA can be a smart way to add a moderate-risk slice. If this is your only annuity purchase, a fixed index annuity is usually the safer choice.
