Fixed vs. Variable vs. Indexed Annuities: 2026 Guide to Picking the Right One

Why Annuity Type Matters More Than the Headline Rate

An annuity is a long-term contract with an insurance company that turns a lump sum (or stream of payments) into guaranteed future income — usually in retirement. But "annuity" is an umbrella term. The three main flavors — fixed, variable, and indexed — behave so differently that picking the wrong one can cost you tens of thousands of dollars over a 20-year payout period.

In 2026, with the 10-year Treasury hovering near 4% and equity markets choppier than they were in the post-2020 boom, annuity sales are running at record levels. According to LIMRA's 2025 industry report, total U.S. annuity sales topped $430 billion last year, with fixed-rate products leading growth.

This guide breaks down what each type actually guarantees, what it costs, and who each one is built for. Pair this with our annuities hub and a real APY comparison from a high-yield savings account before you commit any cash to a multi-year contract.

How Each Annuity Type Actually Works

Fixed Annuities (MYGAs)

A fixed annuity — most often sold today as a Multi-Year Guaranteed Annuity (MYGA) — pays a guaranteed interest rate for a fixed term, much like a CD. The insurer takes your premium, invests it primarily in investment-grade bonds, and credits a fixed APY for 3, 5, 7, or 10 years.

The appeal: predictability. You know exactly what your money will be worth at the end of the term, with no market exposure. For conservative savers comparing certificates of deposit against MYGAs, MYGAs often pay 0.50% to 1.25% more for the same term, with the trade-off of an early-withdrawal "surrender" penalty.

Variable Annuities

A variable annuity lets you invest your premium across subaccounts that look and behave like mutual funds — equity, bond, balanced, sector. Your account value rises and falls with those investments. The "annuity" part is the optional living benefit rider (most commonly a Guaranteed Lifetime Withdrawal Benefit, or GLWB) that promises a minimum income for life regardless of market performance.

The upside is real growth potential. The downside is fees: a typical variable annuity stacks a mortality and expense (M&E) charge (~1.0%), subaccount fees (~0.50%–1.0%), and an income rider (~1.0%–1.5%) for an all-in drag of 2.5%–3.5% per year.

Indexed Annuities (FIAs)

A Fixed Indexed Annuity is the hybrid. Your principal is protected (you can't lose money to market declines), but instead of a flat interest rate, returns are tied to an equity index like the S&P 500 — subject to a cap, participation rate, or spread that limits the upside.

Example: a 1-year point-to-point S&P 500 strategy with an 8% cap means if the index returns 15%, you get 8%; if it returns -10%, you get 0% (not -10%). FIAs have grown the fastest of the three in recent years because they pitch "market-like returns with downside protection" — though in practice the cap is what determines whether that promise holds.

Fees — The Single Biggest Differentiator

Fees are where annuities earn their bad reputation, and they vary wildly by type.

A fixed MYGA has no explicit fee — the insurer's spread is already baked into the credited rate. A variable annuity with an income rider can run 3% all-in, which means a 7% gross return becomes a 4% net return before you've even paid taxes. Over 20 years of compounding, that fee drag can cut your ending balance by 30%–40%.

Indexed annuities sit in the middle. The base contract typically has no annual fee (the insurer makes money on the spread between actual index returns and what gets credited to you), but adding a guaranteed income rider usually costs 0.75%–1.25% per year.

Who Each Annuity Type Fits Best

Fixed (MYGA) is for you if:

• You're comparing rates against CDs and want a slightly higher guaranteed APY.
• You have a known 3–10 year time horizon and won't need the principal back early.
• You want zero market exposure and zero fees.
• You're using IRA money and want tax-deferred growth (otherwise, a CD may be simpler).

Variable is for you if:

• You have a long retirement horizon (15+ years) and want equity growth potential.
• You've maxed out your 401(k) and IRA and need more tax-deferred space.
• You specifically want the guaranteed lifetime income floor a GLWB rider provides.
• You can stomach 2.5%–3.5% in annual fees in exchange for those guarantees.

Indexed (FIA) is for you if:

• You want market upside but cannot afford to lose principal.
• You're 5–15 years from retirement and want to "de-risk" without going all-cash.
• You understand that caps will limit you in strong bull markets.
• You're considering it as a bond-alternative inside a balanced retirement plan.

What to Ask Before Signing

Annuity contracts are dense. Before you sign, get the following in writing:

1. The exact credited rate or cap, the guarantee period, and whether the cap can change at renewal.
2. The full surrender-charge schedule — year by year, with the free-withdrawal percentage clearly stated.
3. Total annual fees, broken out: M&E, admin, subaccount, and any rider fees.
4. The insurer's financial strength rating from AM Best, S&P, and Moody's (look for A or better).
5. A side-by-side illustration showing guaranteed vs. non-guaranteed values at years 5, 10, and 20.

The Bottom Line

A fixed annuity is the right answer for the majority of conservative retirees comparing it against a CD. A variable annuity makes sense in a narrow set of cases — usually for people already maxing out other tax-advantaged accounts who want a guaranteed income floor. An indexed annuity is the middle ground, but its real returns depend almost entirely on the cap, and caps can be reset down at renewal.

Before any annuity, build the basics: an emergency fund in a high-yield savings account, a tax-advantaged retirement account, and a clear picture of your guaranteed income needs in retirement.
