The short answer
A fixed annuity (MYGA) credits a set interest rate for a defined term — predictable and straightforward. A fixed-indexed annuity (FIA) links potential interest to a market index, with a cap or participation rate limiting the upside but protecting against index losses in down years. Neither is invested in the market. Which fits depends on your timeline, need for predictability, and comfort with complexity.
Both products are insurance contracts backed by the issuing insurance company’s financial strength and claims-paying ability — not FDIC-insured, not bank-guaranteed, and not a deposit. Understanding the structure of each is the first step to knowing whether either belongs in your retirement plan.
What a fixed annuity (MYGA) is
A fixed annuity — often called a MYGA, or multi-year guaranteed annuity — is the simpler of the two structures. You deposit a lump sum; the insurance company credits a set interest rate for a defined term. At the end of the term, you typically have the option to renew, convert, or take your accumulated value. The mechanics are close to a CD in terms of predictability, with two important differences: annuities are insurance products backed by the issuer (not the FDIC), and they carry a surrender period with charges if you withdraw more than the contract allows before it ends.
What a fixed annuity does well: certainty. You know the rate going in and can plan around it. What it does not do: it will not participate in market gains, and a fixed rate can lose buying power to inflation over a long term.
What a fixed-indexed annuity (FIA) is
A fixed-indexed annuity credits interest based on the movement of a market index — such as the S&P 500 or another index the contract uses — but your money is not invested in that index. Instead, the contract uses a formula with built-in limits to turn index movement into credited interest. Those limits are called a cap (a ceiling on the interest credited for a period), a participation rate (the share of the index’s gain used in the calculation), or a spread (an amount subtracted before interest is credited). If the index has a down period, the credited interest is typically zero — not negative. If the index rises, you receive some portion of that gain, up to the contract’s limits.
What an FIA does well: it offers some potential for higher interest in favorable periods while protecting against direct index losses. What it does not do: you will not receive the full index return, complexity is higher than a MYGA, and caps and participation rates can change at renewal within the contract’s terms. Any guarantee in the contract is backed by the issuing insurance company — not the FDIC or any government program.
Fixed annuity vs. fixed-indexed annuity, side by side
| Feature | Fixed annuity (MYGA) | Fixed-indexed annuity (FIA) |
|---|---|---|
| How interest is credited | A set rate for a defined term | Tied to index movement, within caps/participation limits |
| Money invested in the market | No | No — index is a reference, not an investment |
| Downside exposure to the index | Not applicable (rate is fixed) | Typically none — floor is zero credited interest, not a loss |
| Upside potential | Limited to the fixed rate | Higher than zero in favorable periods, but limited by the contract |
| Complexity | Lower — rate and term are stated | Higher — caps, participation rates, and spreads vary by contract |
| Backed by | Issuing insurance company (not FDIC) | Issuing insurance company (not FDIC) |
| Surrender period | Yes — charges apply on early excess withdrawal | Yes — charges apply on early excess withdrawal |
Table is for education only. Specific contract terms, rates, caps, and participation rates vary by product and issuer. No contract terms are quoted or guaranteed here. Guarantees are backed by the issuing insurance company’s claims-paying ability — not FDIC-insured.
The trade-offs in plain language
The decision between a fixed annuity and a fixed-indexed annuity is essentially a decision about simplicity versus potential:
- If you want to know exactly what your money will earn and prefer the simplest contract to evaluate, a fixed annuity gives you that clarity at the cost of no participation in market-linked gains.
- If you want the possibility of higher interest in favorable index periods — while still not being directly exposed to index losses — an FIA introduces that possibility at the cost of greater complexity and less certainty about the interest you’ll actually receive.
Neither product is a substitute for a diversified investment strategy, and neither is appropriate for every situation. Both carry surrender periods that limit access to your money in the short term — which is a real liquidity trade-off to weigh against your timeline and income needs.
The honest framing: we explain both structures, including the trade-offs, before anything else. We act in your interest — CA SB 263 (eff. Jan 1, 2025) requires that annuity recommendations be made in your best interest, and that is how we work regardless.
How to think about which one fits
These are the questions that tend to matter most in the decision:
- How much predictability do you need? If your retirement income plan depends on knowing a number with certainty, the MYGA’s fixed rate is easier to plan around.
- How long can you leave the money in place? Both products have surrender periods. Understanding the length and schedule before committing is essential — not secondary.
- How comfortable are you with moving parts? An FIA’s caps and participation rates are real complexity. If reviewing a contract and understanding how renewal terms can change feels burdensome, the MYGA’s simplicity is a genuine advantage.
- What role does this money play in your overall plan? Neither product is the right container for money you may need quickly, or for a portion of savings you want exposed to full market returns. Knowing the role helps identify the right tool.
Common questions
What is the difference between a fixed annuity and a fixed-indexed annuity?
A fixed annuity (often called a MYGA, or multi-year guaranteed annuity) credits a set interest rate for a defined term — you know exactly what rate applies for that period. A fixed-indexed annuity credits interest tied to the movement of a market index, limited by a cap or participation rate, and does not credit less than zero in a down period. Neither product is invested in the market.
Are annuities FDIC-insured?
No. Annuities are insurance products, not bank deposits. They are not FDIC-insured, not bank-guaranteed, and not backed by any government deposit-insurance program. Any guarantee in an annuity contract depends entirely on the financial strength and claims-paying ability of the issuing insurance company.
Can I lose money in a fixed-indexed annuity?
A fixed-indexed annuity is designed so that your credited value does not decrease because of a negative index return in a given period — the floor is typically zero credited interest, not a loss. However, you can still face surrender charges if you withdraw more than the contract permits during the surrender period. "No index loss" is not the same as "no trade-offs."
Which one is right for me — fixed or fixed-indexed?
It depends on what you need the money to do. If you want the simplest structure — a known rate, a defined term, no complexity — a fixed annuity is often easier to evaluate. If you want some potential for higher interest in favorable index periods, within limits, a fixed-indexed annuity introduces that possibility at the cost of additional complexity. The trade-offs of each become clearer when you look at your specific timeline, liquidity needs, and comfort with moving parts.
What is a surrender charge and how does it apply to both types?
A surrender charge is a fee applied if you withdraw more than the contract's allowable amount during the surrender period. Both fixed annuities and fixed-indexed annuities typically carry a surrender period. The charge generally starts higher and declines over time, reaching zero when the period ends. Understanding the surrender schedule is an essential part of evaluating either product.
