FIA vs. RILA — Fixed Indexed vs. Registered Index-Linked Annuity

By Editorial Team

Published April 1, 2026 · Updated May 5, 2026

A fixed indexed annuity (FIA) protects 100% of your principal from market losses with a 0% floor, while a registered index-linked annuity (RILA) uses buffers to absorb a portion of losses — typically 10–20% — in exchange for significantly higher growth potential. Choose an FIA if you cannot afford any loss; choose a RILA if you want higher caps and can accept limited downside beyond the buffer.

FIA vs. RILA: Head-to-Head Comparison

Feature	FIA	RILA
Downside protection	100% — 0% floor, no losses ever	Partial — 10–20% buffer absorbs first losses
Upside potential	Moderate — caps 7–10%, or participation rate	Higher — caps 15–25%+ on same index
Can you lose money?	No (from index losses)	Yes — losses beyond the buffer
Regulatory body	State insurance department only	SEC + FINRA + state insurance dept.
License required to sell	Life insurance license only	Securities license (Series 6 or 7) required
Typical fees	No explicit fee (unless income rider); ~0.75–1.25% for riders	Low explicit fees; ~0.95–1.60% with income riders
Income riders	Widely available from most FIA carriers	Available but less common; fewer options
Best for	Near retirees, income-focused, loss-averse	10+ year horizon, moderate risk tolerance, growth

How FIA Protection Works

A fixed indexed annuity (FIA) is an insurance contract that links interest credits to the performance of an external index — most commonly the S&P 500 Price Return Index — subject to a hard floor of 0%. No matter how badly the index performs in a given contract year, you cannot receive a negative credit. Your previously credited interest is locked in permanently through the annual reset mechanism: each year’s starting value becomes the new baseline, so prior gains can never be taken back by a subsequent market downturn.

The trade-off for this absolute protection is that your upside is limited by the carrier’s crediting parameters. Under a cap rate, you receive up to the stated ceiling (e.g., 9%) regardless of how much the index gains. Under a participation rate, you receive a fixed percentage of the index gain — often 60–150% depending on the index and contract. Under a spread, a fixed percentage is deducted from the gain before crediting. The carrier can change these parameters annually within contractual minimums.

Top FIA carriers include Athene Performance Elite, Allianz 360, NAC Performance Choice, and Nationwide New Heights.

How RILA Buffers Work

A registered index-linked annuity (RILA) — also called a buffer annuity or structured annuity — offers partial downside protection through a buffer. A 10% buffer means the carrier absorbs the first 10% of index losses; you only lose if the index drops more than 10%. A 15% buffer absorbs the first 15%. Some products offer a -10% floor instead of a buffer — meaning you absorb losses up to 10% and the carrier absorbs everything beyond that.

Because the carrier is accepting some loss risk (rather than all of it, as with an FIA), it can use the freed-up capital to purchase more expensive options on the index — resulting in significantly higher caps. Where an FIA might cap S&P 500 gains at 9%, a RILA with a 15% buffer might cap gains at 22% on the same index over the same term. This trade-off is the core of the product: more upside, but not fully protected from a catastrophic market year.

RILAs are registered securities, meaning they carry a prospectus and must be sold by a licensed registered representative. This regulatory structure allows carriers more investment flexibility, which is part of why RILA caps are structurally higher than FIA caps.

Real Numbers: What Happens in a Down Market

Consider a scenario where the S&P 500 drops 25% in a single contract year. Here is how each product type responds:

Product	Index Return	Protection	You Receive
FIA (0% floor)	−25%	Full floor — no losses allowed	0% credit (no loss)
RILA (15% buffer)	−25%	Buffer absorbs first 15%	−10% (loss beyond buffer)
RILA (20% buffer)	−25%	Buffer absorbs first 20%	−5% (loss beyond buffer)
RILA (−10% floor)	−25%	Floor caps your loss at −10%	−10% (you bear losses up to floor)
Traditional VA (no rider)	−25%	None	−25% (full loss)

Now consider a strong year where the index gains 20%:

Product	Index Return	Cap / Limit	You Receive
FIA (9% cap)	+20%	Capped at 9%	+9%
RILA (22% cap, 15% buffer)	+20%	Cap not reached	+20%
Traditional VA	+20%	No cap (sub-account)	+20% (less ~3% fees)

The scenario above illustrates why a 2008-style crash (-38% in one year) makes the FIA’s 0% floor enormously valuable — while a sustained bull market with moderate gains rewards the RILA’s higher caps. The “right” choice depends on which scenario you’re more exposed to given your timeline.

When to Choose an FIA

An FIA is the right choice when you are within 5 years of needing income, cannot afford any account value loss, or are pairing the contract with an income rider for guaranteed lifetime withdrawals. The 0% floor means there is no “bad timing” risk from a severe market correction shortly after purchase. Income rider rollup rates on leading FIAs — often 5–7% annually on the income base — allow the income benefit to grow even in flat or declining markets.

FIAs are also appropriate for conservative investors who understand the product structure and want equity-linked upside without equity-linked downside. If your alternative is a bank CD or a fixed annuity, an FIA with a competitive participation rate can deliver meaningfully better returns in positive market years while preserving all downside protection.

When to Choose a RILA

A RILA is appropriate when you have a longer time horizon (10+ years), can accept limited downside exposure in exchange for substantially higher growth potential, and don’t need income in the near term. The math favors RILAs in environments where markets are consistently positive or mildly negative — a 15% buffer protects you in most years that aren’t catastrophic, while the higher cap lets you capture much more of strong bull-market years.

RILAs are also ideal for investors who are currently in stocks but want partial protection as they approach retirement — using a RILA as a “glide path” product that limits downside while maintaining meaningful upside. For someone with a 10-year horizon, a portfolio of RILA segments with 15–20% buffers can outperform FIAs on a risk-adjusted basis, particularly in the moderate market scenarios that characterize most decades.
