The fixed annuity vs variable annuity choice turns on one trade-off: a fixed annuity credits a set interest rate and protects your principal, while a variable annuity ties your value to investment subaccounts that can grow faster but can also lose money. Both grow tax-deferred and are taxed the same way on withdrawal; what actually differs is market risk, the fee load, and how each product is regulated.
In a fixed annuity vs variable annuity comparison, a fixed annuity guarantees a set interest rate and protects principal, so the insurer bears market risk. A variable annuity invests in mutual-fund-like subaccounts where you can lose money, per the SEC. Both grow tax-deferred and are taxed as ordinary income on withdrawal (IRS Pub 575). Variable annuities add a mortality and expense charge near 1.25% per year (SEC); fixed annuities carry little or no explicit ongoing fee.
Fixed annuity vs variable annuity: the core difference
The core difference in a fixed annuity vs variable annuity is who bears the investment risk. A fixed annuity credits a set, declared interest rate and protects principal, so the insurance company carries the market risk. A variable annuity places your money in subaccounts that rise and fall with markets, so you carry the risk and can lose principal (SEC).

The U.S. Securities and Exchange Commission describes variable annuity subaccounts as “typically mutual funds that invest in stocks, bonds, money market instruments, or some combination” and states plainly that you “can lose money in a variable annuity, including potential loss of your original investment” (Source: SEC/Investor.gov, Updated Investor Bulletin: Variable Annuities).
A fixed annuity works the other way. It credits a rate set by the individual contract under state insurance law, not by federal rules, and holds principal steady for the guarantee period. The practical effect is predictability: a known rate and protected principal in exchange for giving up the higher upside a variable contract can offer.
At-a-glance comparison table
This table summarizes how a fixed annuity and a variable annuity differ across the features that most affect a retirement decision: return mechanics, principal protection, fees, regulation, and tax treatment. Every dollar and percentage figure carries a year and a source; contract-specific items such as surrender schedules vary by insurer and are set out in the contract or prospectus.
| Feature | Fixed annuity | Variable annuity |
|---|---|---|
| Return | Set, declared interest rate; predictable | Depends on subaccount performance; higher upside potential |
| Principal | Protected by the contract | Not guaranteed; can decline (SEC) |
| Who bears market risk | The insurer | The owner |
| Ongoing fees | Little to none as explicit charges | M&E near 1.25%/yr plus admin, fund, and rider fees (SEC) |
| Regulation | Insurance product; state-regulated | Security; SEC and FINRA, sold with a prospectus |
| Tax growth | Tax-deferred (IRS Pub 575) | Tax-deferred (IRS Pub 575) |
| Withdrawal tax | Ordinary income on gains (10% to 37% in 2026) | Ordinary income on gains (10% to 37% in 2026) |
| Pre-59½ penalty | 10% federal early-distribution tax (IRS Topic 558) | 10% federal early-distribution tax (IRS Topic 558) |
| Backstop if issuer fails | State guaranty association (limits vary) | Subaccounts held in a separate account |
What is a fixed annuity?
A fixed annuity is an insurance contract that credits a set interest rate for a stated period and protects your principal. Because the insurer guarantees the rate, growth is predictable and generally lower than the potential upside of a market-linked product. Fixed annuities are insurance products regulated by state insurance departments, not securities registered with the SEC.
The defining feature is certainty. A multi-year guaranteed annuity, often called a MYGA, locks a rate for a fixed term such as three, five, or seven years. The exact declared and guaranteed-minimum rates come from state insurance law and each contract, so no single federal figure applies.
Because a fixed annuity is not a security, it is not backed by the SEC or SIPC. If the issuing insurer becomes insolvent, coverage may come through your state guaranty association, whose dollar limits vary by state. That backstop, plus the insurer’s own financial strength, is where the safety of a fixed annuity sits.
What is a variable annuity?
A variable annuity is a contract that invests your money in subaccounts, typically mutual funds holding stocks, bonds, or money market instruments, and layers insurance features on top. Its value moves with those investments. The SEC states value depends on “the performance of the investment options you choose,” and that you “can lose money in a variable annuity, including potential loss of your original investment” (Source: SEC/Investor.gov).
Variable annuities are securities, so they are regulated by the SEC and FINRA and sold with a prospectus. FINRA suitability rules and Regulation Best Interest govern how they are recommended, a framework that grew out of long-running concern about high-commission annuity sales.
A structural point most comparison pages skip: variable subaccounts sit in a separate account, apart from the insurer’s general account, so their value follows the underlying funds rather than the insurer’s own solvency. Many contracts add a death-benefit guarantee. The SEC describes a beneficiary generally receiving “the greater of: (i) all the money in your account; or (ii) some guaranteed minimum (such as all purchase payments minus prior withdrawals).”
The fee gap and how it drags returns
Fee load is a defining practical difference in a fixed annuity vs variable annuity comparison. A fixed annuity carries little or no explicit ongoing charge because the insurer keeps the spread between what it earns and the rate it credits. A variable annuity discloses a stack of fees that compound against your return every year, and the SEC notes tax deferral may outweigh those costs only over a long holding period.
The variable fee stack typically includes:
- Mortality and expense (M&E) risk charge: the SEC states this is “typically in the range of 1.25% per year” of account value (Source: SEC/Investor.gov).
- Administrative fees: charged for recordkeeping and account services.
- Underlying fund fees: the expense ratios of the mutual-fund subaccounts you select.
- Optional rider fees: for features such as guaranteed lifetime income or an enhanced death benefit.
These layers compound against gross return, so the size of the fee stack in a specific contract is a central item to check in the prospectus. Fee alarmism can overshoot, though: low-cost and no-load variable annuities exist, strip out sales commissions, and can hold total costs well below a fully loaded contract.
One honest comparison that many sales pitches omit is against a plain taxable low-cost index fund. Inside a variable annuity, all gains come out as ordinary income taxed at 2026 rates of 10% to 37%. A taxable index fund instead produces long-term capital gains taxed at 0%, 15%, or 20% (the 0% rate runs to $49,450 of taxable income for single filers and $98,900 for married couples filing jointly in 2026) and can pass a step-up in basis to heirs. For investors already weighing tax brackets, modeling these paths beside a Roth conversion strategy often makes the trade-offs clearer, since it can frame how long a tax move needs to work.
Fixed vs variable vs fixed-indexed: the third option
A third product sits between the two and is often confused with a variable annuity: the fixed-indexed annuity. It credits interest linked to a market index such as the S&P 500 while typically protecting principal from index losses, usually in exchange for caps or participation rates that limit the upside. It is not a variable annuity, because your money is not invested directly in market subaccounts.
The clean three-way framing is straightforward. Fixed means a set rate and protected principal. Fixed-indexed means index-linked crediting with downside protection and a capped upside. Variable means direct market exposure with no principal guarantee. Because a fixed-indexed annuity is generally not a security, it is regulated as a state insurance product rather than by the SEC.
Taxes: identical for both in 2026
Fixed and variable annuities receive identical federal tax treatment, so taxes rarely decide between them. Both grow tax-deferred, and withdrawals of earnings are taxed as ordinary income, not at lower capital-gains rates (Source: IRS Pub 575). For 2026, ordinary rates run 10%, 12%, 22%, 24%, 32%, 35%, and 37%, made permanent by the One Big Beautiful Bill Act (P.L. 119-21).
The IRS states “the taxable part of a distribution is treated as ordinary income” (Source: IRS Pub 575). Withdrawals of earnings before age 59½ generally trigger a 10% federal early-distribution tax under IRC Section 72 (Source: IRS Topic 558), on top of the ordinary income tax.
Two mechanics matter for a nonqualified deferred annuity. Withdrawals are income-first (a LIFO rule): the IRS allocates them “first to earnings (the taxable part) and then to your cost” (Source: IRS Pub 575), so early withdrawals are fully taxable until the gain is used up. Once you annuitize, the exclusion ratio under IRC Section 72(b)(1) makes part of each payment tax-free until you recover your cost basis.
Because annuity income lands as ordinary income, it can interact with related thresholds in a given year. Large withdrawals can affect the 3.8% net investment income tax that applies above $200,000 of modified AGI for single filers and $250,000 for joint filers in 2026, and, for qualified annuities, feed into required minimum distributions once you reach RMD age.
Which is better, and who each annuity may suit
Neither annuity is universally better; suitability maps to risk tolerance and time horizon. A conservative saver near retirement who prioritizes protected principal and predictable income may lean toward a fixed annuity. Someone with a longer horizon and higher risk tolerance who wants market upside inside a tax-deferred wrapper may consider a variable annuity, accepting its fees and the real chance of loss.
Inflation cuts both ways. A fixed payout can lose purchasing power over time because the dollar amount does not rise. A variable payout can increase when markets perform, offering a potential inflation hedge, but it can also fall. Both products can offer guaranteed lifetime income through annuitization, which addresses the risk of outliving your money on either side.
One annuity-specific 2026 figure applies to qualified plans and IRAs: the Qualifying Longevity Annuity Contract (QLAC) premium limit is $210,000 for 2026 (Source: IRS Notice 2025-67). Given the fee, guarantee, and tax variables, many people compare options alongside their broader plan, including questions such as how much to convert to Roth and the Roth conversion deadline for 2026, with a qualified professional before buying.

Frequently asked questions
Which is better, a fixed or variable annuity?
Neither is universally better; it depends on risk tolerance and time horizon. A variable annuity offers higher upside potential but carries market risk and fees such as a mortality and expense charge near 1.25% per year (SEC). A fixed annuity offers predictable, protected growth with little or no explicit ongoing fee. Many investors near retirement favor certainty; those with a longer horizon may accept variable risk.
What is the downside of a variable annuity?
The main downsides are market risk with possible loss of principal and a layered fee stack: a mortality and expense charge near 1.25% per year (SEC), plus administrative fees, underlying fund fees, and optional rider fees. Surrender charges may apply to early withdrawals, and all gains come out as ordinary income taxed at 2026 rates of 10% to 37%, rather than at lower capital-gains rates.
Can you lose money in a fixed annuity?
A fixed annuity protects principal by crediting a set interest rate rather than exposing money to markets, so it does not lose value to market swings. The main risks are insurer credit risk, backstopped by state guaranty associations whose limits vary by state, and surrender charges if you withdraw early. Inflation can also erode the purchasing power of a fixed payout over time.
What is the difference between a fixed and variable annuity?
A fixed annuity credits a set interest rate and protects your principal, so the insurer carries market risk. A variable annuity invests in mutual-fund-like subaccounts whose value fluctuates, and the owner can lose money, per the SEC. Fixed annuities are state-regulated insurance products; variable annuities are securities regulated by the SEC and FINRA and sold with a prospectus. Both grow tax-deferred.
Are variable annuities a good investment?
A variable annuity may fit an investor with a long time horizon and higher risk tolerance who wants tax-deferred market growth and is comfortable with fees near or above 1.25% per year (SEC) plus possible loss of principal. It is often less efficient than a taxable low-cost index fund for pure growth, because gains convert to ordinary income. Suitability depends on individual circumstances and the specific contract.
