The variable vs fixed annuity choice comes down to one trade-off: a fixed annuity credits a set interest rate and protects principal, while a variable annuity ties your value to investment subaccounts that can grow faster but can also lose money. Both share identical federal tax treatment; the differences are product features, fees, and how much market risk you accept.
A fixed annuity guarantees a set interest rate and principal; 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, 2026). Variable annuities carry a mortality and expense charge around 1.25% per year (SEC).
Variable vs fixed annuity: the core difference
A defining difference is who bears the investment risk. A fixed annuity credits a set interest rate for a stated period and protects your 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.

The U.S. Securities and Exchange Commission describes a variable annuity as “an investment account that may grow on a tax-deferred basis” whose subaccounts “are typically mutual funds that invest in stocks, bonds, money market instruments, or some combination” (Source: SEC/Investor.gov, Updated Investor Bulletin: Variable Annuities). The SEC states plainly: “You can lose money in a variable annuity, including potential loss of your original investment.”
A fixed annuity works differently. It credits a declared interest rate, and the exact rate mechanics are set by state insurance law and the individual contract rather than by federal rules. The general effect is predictability: a known rate and protected principal for the guarantee period. If you are still learning the product category itself, the Q3 Advisors buyer’s guide to annuities covers the basics this page assumes.
At-a-glance comparison table
The table below summarizes how a fixed 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 figure carries a year and source; product-specific items such as surrender schedules vary by contract.
| 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) |
| Investment risk | Borne by the insurer | Borne by the owner |
| Ongoing fees | Little to none disclosed as explicit charges | M&E ~1.25%/yr plus admin, fund, and rider fees (SEC) |
| Regulation | Insurance product; state-regulated | Security; SEC and FINRA regulated |
| Tax growth | Tax-deferred (IRS Pub 575) | Tax-deferred (IRS Pub 575) |
| Withdrawal tax | Ordinary income on gains | Ordinary income on gains |
| Early-withdrawal penalty | 10% before age 59½ (IRS Topic 558) | 10% before age 59½ (IRS Topic 558) |
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 market-linked products. Fixed annuities are insurance products regulated by state insurance departments, not securities.
A defining feature is certainty. A multi-year guaranteed annuity, often called a MYGA, locks a rate for a fixed term. The specific declared and guaranteed-minimum rates come from state insurance law and each contract, so no single federal figure applies. What is defensible in general terms is the structure: a known rate and protected principal for the guarantee window.
Because fixed annuities are not securities, they are not registered with the SEC. Protection instead comes through state guaranty associations, which provide coverage limits that vary by state if an insurer becomes insolvent. That state-level backstop is a meaningful distinction from how variable subaccounts are structured.
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 adds insurance features. 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, Updated Investor Bulletin: Variable Annuities).
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 these products are recommended, a response to a long history of concern about high-commission sales.
A key structural point often missing from comparison pages: variable subaccounts sit apart from the insurer’s general account, so their value follows the underlying funds rather than the insurer’s own solvency. Many variable 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 the sharpest practical difference. Fixed annuities carry little or no explicit ongoing charge because the insurer keeps the spread between what it earns and the rate it credits. Variable annuities disclose a stack of fees that compound against your return every year, which is why the SEC warns that tax-deferral benefits “may outweigh the costs of a variable annuity only if you hold it as a long-term investment.”
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, Updated Investor Bulletin: Variable Annuities).
- Administrative fees: charged for recordkeeping and account services.
- Fund/investment management fees: the expense ratios of the underlying subaccounts.
- Optional rider fees: for features such as guaranteed lifetime income or enhanced death benefits.
Added together, these layers form a combined annual cost that the SEC cautions can reduce the value of a variable annuity, which is why it frames tax deferral as a benefit that “may outweigh the costs of a variable annuity only if you hold it as a long-term investment.” Any annual cost compounds against gross return over time, so the size of the fee stack in a specific contract is a central item to examine in the prospectus. Low-cost or no-load variable annuities exist and strip out sales loads, which changes the cost picture. Investors weighing fees against other tax moves sometimes model them alongside a Roth conversion as factors to weigh with a qualified professional.
Do not confuse variable with fixed-indexed
A third product sits between the two and is frequently confused with a variable annuity: the fixed-indexed annuity. It credits interest linked to a market index such as the S&P 500 but typically protects 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: fixed means a set rate and protected principal; fixed-indexed means index-linked crediting with downside protection and 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 an insurance product rather than by the SEC, unlike a variable annuity.
Taxes: identical for both
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, 2026; SEC/Investor.gov). Growth compounds untaxed until you take money out.
The IRS states “the taxable part of a distribution is treated as ordinary income” (Source: IRS Pub 575). For 2026, ordinary rates run 10/12/22/24/32/35/37%, made permanent by the One Big Beautiful Bill Act (Source: IRS Rev. Proc. 2025-32). Withdraw earnings before age 59½ and a 10% federal early-distribution tax generally applies under IRC §72 (Source: IRS Topic 558).
Two mechanics matter. Non-annuity withdrawals from a nonqualified deferred annuity are income-first: allocated “first to earnings (the taxable part) and then to your cost” (Source: IRS Pub 575). Once annuitized, the exclusion ratio under IRC §72(b)(1) makes part of each payment tax-free until your cost is recovered. Because withdrawals land as ordinary income, they can interact with related thresholds such as the net investment income tax, Medicare IRMAA brackets, and required minimum distributions in a given year.
Who each annuity may suit
Suitability maps to risk tolerance and time horizon rather than to a universal rule. 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 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 longevity risk on either side.
One annuity-specific 2026 figure applies to qualified plans: the Qualifying Longevity Annuity Contract (QLAC) premium limit is $210,000 for 2026 (Source: IRS Notice 2025-67). Given the fee, guarantee, and suitability variables, many people compare options with a professional; the Q3 Advisors advisory team works in the retirement-tax area specifically.

Frequently asked questions
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 insurance products; variable annuities are securities regulated by the SEC and FINRA.
Is a variable annuity better than a fixed 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 around 1.25% per year (SEC). A fixed annuity offers predictable, protected growth with little or no explicit ongoing fee.
Can you lose money in a variable annuity?
Yes. The SEC states you “can lose money in a variable annuity, including potential loss of your original investment,” because value depends on the performance of the subaccounts you choose (Source: SEC/Investor.gov, Updated Investor Bulletin: Variable Annuities). A fixed annuity, by contrast, protects principal by crediting a set interest rate rather than exposing money to markets.
What are the disadvantages of a variable annuity?
Key disadvantages include market risk with possible loss of principal and a layered fee stack: a mortality and expense charge around 1.25% per year (SEC), plus administrative fees, underlying fund management fees, and optional rider fees that add to the total annual cost. Surrender charges may apply to early withdrawals, and gains are taxed as ordinary income on withdrawal.
Who might a fixed annuity suit?
A fixed annuity may suit a conservative saver, often near retirement, who prioritizes protected principal and a predictable interest rate over market upside. Because the insurer bears investment risk and fees are minimal, it can appeal to those with lower risk tolerance. Suitability depends on individual circumstances; many people consult a financial professional first.
Are annuities taxed as ordinary income?
Yes. The IRS states “the taxable part of a distribution is treated as ordinary income” for both fixed and variable annuities (Source: IRS Pub 575, 2026), taxed at rates rather than lower capital-gains rates. For 2026, ordinary brackets run 10% to 37% (Source: IRS Rev. Proc. 2025-32). Growth stays tax-deferred until withdrawal.
What are the fees on a variable annuity?
Variable annuity fees typically include a mortality and expense (M&E) charge “in the range of 1.25% per year” (Source: SEC/Investor.gov, Updated Investor Bulletin: Variable Annuities), administrative fees, underlying fund management fees, and optional rider fees. Together these layers form the total annual cost, which is disclosed in the prospectus and varies by contract. Fixed annuities carry little or no explicit ongoing fee.
Is a fixed annuity safe?
A fixed annuity protects principal by crediting a set interest rate rather than exposing money to markets, and it is backed by the issuing insurer and by state guaranty associations whose coverage limits vary by state. It carries insurer credit risk rather than market risk. As with any product, safety depends on the insurer and contract terms.
