Variable Annuity Explained: How It Works, Fees, and Risks

A variable annuity is a contract with an insurance company in which your money is invested in a menu of market-based investment options, so the account value rises and falls with those investments rather than sitting at a fixed rate. Because the value can go up or down, the insurer does not guarantee your principal or a set return unless you pay extra for a feature that adds one. In the United States, variable annuities are treated as securities: they are sold with a prospectus and are regulated by the Securities and Exchange Commission (SEC) and the Financial Industry Regulatory Authority (FINRA), not just by state insurance departments.

That single fact, that a variable annuity carries investment risk, separates it from the fixed and fixed index products most people picture when they hear the word annuity. The rest of this guide explains the moving parts: how the two phases work, what the subaccounts are, the layered fees that make these contracts expensive, the optional riders, the tax treatment, and the situations where a variable annuity does or does not earn its keep. If you are new to the category, start with our plain-English guide to how annuities work and come back.

How a Variable Annuity Works: The Two Phases

Like other deferred annuities, a variable annuity has an accumulation phase and a distribution phase.

During the accumulation phase, you contribute money, either as a lump sum or over time, and allocate it across investment options inside the contract. The value grows or shrinks based on how those investments perform. Earnings are not taxed while they stay in the contract.

During the distribution phase, you decide how to take the money out. You can withdraw it, leave it to a beneficiary, or annuitize, which means converting the balance into a stream of income payments. Some contracts let you take flexible withdrawals indefinitely without ever formally annuitizing.

The defining difference from a fixed annuity is what drives the account value. A fixed annuity credits a rate the insurer sets. A fixed index annuity credits interest linked to an index, subject to caps and other limits, but cannot lose value from market declines. A variable annuity passes the actual investment results, gains and losses, through to you.

What the Subaccounts Are

The investment options inside a variable annuity are called subaccounts. They function much like mutual funds, holding stocks, bonds, or a mix, but they exist inside the insurance contract rather than in a standalone brokerage account.

A typical contract offers a menu of subaccounts spanning different asset classes and risk levels: large-company stock, international stock, bonds, money market, and various blended or target-style options. You choose how to split your money among them and can usually move between them, sometimes with limits on frequency.

Two consequences follow from this structure:

• Your return is not guaranteed. If the subaccounts you chose fall in value, so does your account, unless a paid rider provides a floor.
• The underlying funds have their own expenses. Each subaccount charges a fund-level fee that comes out of its return, on top of the insurance charges described below.

The Fees: Why Variable Annuities Are Expensive

Cost is the issue most often glossed over in a sales conversation, so it deserves plain treatment. Variable annuities tend to carry several layers of charges that stack on top of each other. The prospectus lists them in full, and FINRA requires that customers be told, in general terms, about these features before buying.

Charge	What it pays for
Mortality and expense (M&E) risk charge	The insurer's guarantees, such as a death benefit and the promise to make payments, plus profit
Administrative fee	Record-keeping and contract servicing
Underlying fund expenses	The cost of running each subaccount you invest in
Rider charges	Optional guarantees you choose to add, such as an income or death-benefit rider
Surrender charge	A declining penalty for withdrawing more than an allowed amount during the early years

These are not trivial. Layered together, the annual drag on a variable annuity is commonly well above the cost of holding low-fee index funds directly. None of these figures are quoted here because they vary by contract and change over time; read the specific prospectus and the fee table before you sign. For the mechanics of how surrender schedules work, see our guide to annuity fees and surrender charges.

The reason fees matter so much is compounding in reverse. A percentage skimmed every year, on a balance you hope will grow for decades, is a large lifetime number even when the annual figure sounds small.

Optional Riders and Guarantees

Much of the appeal advertised for variable annuities comes from optional riders, which are add-on guarantees you pay extra for. Common ones include:

• Guaranteed minimum income benefit. Promises a minimum income base for calculating future payments, regardless of how the subaccounts perform.
• Guaranteed minimum withdrawal benefit. Lets you withdraw a set percentage each year for life, even if the account value falls to zero from withdrawals and poor returns.
• Enhanced or stepped-up death benefit. Pays beneficiaries at least your contributions, or a locked-in high-water value, rather than the current account value if it has dropped.

Riders can genuinely transfer some risk to the insurer. The trade is that each one adds an annual charge and usually comes with rules: the guaranteed figure is often a separate "benefit base" used only to calculate income or death benefits, not a cash value you can walk away with. Read how each rider defines its terms, because the marketing headline and the contract language are not always the same thing.

How a Variable Annuity Is Taxed

A variable annuity is tax-deferred: investment earnings are not taxed while they remain inside the contract. How withdrawals are taxed depends on whether the contract is qualified or non-qualified.

Non-qualified contracts are bought with after-tax money. When you take money out, earnings come out first for tax purposes and are taxed as ordinary income, not at lower long-term capital gains rates. Your original after-tax contributions come back tax-free once earnings are exhausted, or are split out under an exclusion ratio if you annuitize.

Qualified contracts are held inside a retirement account such as an IRA. In that case the tax treatment follows the account, and required minimum distribution rules can apply.

Two points are worth emphasizing because they surprise people. First, gains are taxed as ordinary income, which can be a higher rate than the capital gains treatment those same investments might receive in a taxable brokerage account. Second, withdrawals of earnings before age 59½ may face an additional 10% IRS early-distribution penalty on the taxable portion. Tax rules are detailed and change; confirm specifics with the IRS or a tax professional, and see our overview of retirement tax planning for the wider picture.

Variable vs Fixed and Index Annuities

It helps to place the variable annuity next to its relatives, because the right comparison depends on how much market risk you want.

• Fixed annuity (including MYGA). The insurer sets the rate; your principal does not fall with the market. Lowest risk, no market upside.
• Fixed index annuity. Interest is linked to an index but cannot go negative; caps and participation rates limit the upside. Middle ground.
• Variable annuity. Full market exposure through subaccounts; the most upside potential and the only one of the three where the account value can fall from market losses. Highest fees of the three.

If your main goal is guaranteed income timing rather than growth, the choice between starting income now or later may matter more than the variable-versus-fixed decision. Our guide to immediate vs deferred annuities walks through that timeline question.

Who a Variable Annuity Might Suit, and Who It Usually Does Not

A variable annuity is a specialized tool, not a default. It tends to make the most sense for someone who has already maxed out lower-cost tax-advantaged accounts, wants additional tax-deferred growth, can tolerate market risk, and specifically values a guarantee that a rider provides and is willing to pay for. The tax deferral is more meaningful to a person many years from withdrawals and in a high current tax bracket.

It tends to fit poorly for someone who simply wants safe, predictable income, who would be better served by a fixed or income annuity at far lower cost; for someone who has not yet filled cheaper tax-advantaged accounts; or for anyone who does not understand or need the riders being sold. Surrender charges also make these contracts a poor fit for money you might need in the early years.

Because variable annuities are securities, the person recommending one to you is held to specific suitability and disclosure standards under FINRA rules. You are entitled to the prospectus, and you should read the fee table and the rider definitions before deciding. A guarantee you do not need is not worth its annual charge, and a low-fee alternative may reach the same goal.

A Note on Illustrations and Safety

If you are shown a projection of future values, treat it as an illustration built on assumed returns, not a promise. Actual results depend on the subaccounts you pick and the markets. Rates, fees, and rider terms change; verify every figure against the current prospectus before acting.

On safety: the insurance guarantees in a variable annuity, such as a death benefit or income rider, rest on the issuing insurer's claims-paying ability. The subaccount investments themselves are held separately from the insurer's general account, which affects how they are treated if the insurer fails. State guaranty associations provide a backstop for certain insurance obligations up to state-specific limits, but coverage varies by state and does not work like federal deposit insurance. You can verify an insurer's standing through your state insurance department.

Variable Annuity: Frequently Asked Questions

Can a variable annuity lose money?

Yes. Because your money is invested in market subaccounts, the account value can fall when those investments decline. Unless you have paid for a rider that provides a floor or guaranteed income base, there is no protection against market losses. This is the central difference from a fixed or fixed index annuity.

Why are variable annuities considered expensive?

They typically stack several charges: a mortality and expense risk charge, an administrative fee, the expenses of each underlying subaccount, and the cost of any optional riders, plus a surrender penalty in the early years. Layered together, the annual cost is usually well above holding comparable low-fee funds directly. The exact figures are in the contract's fee table.

How is a variable annuity different from a mutual fund?

The subaccounts resemble mutual funds, but they sit inside an insurance contract. That wrapper adds tax deferral and optional insurance guarantees, but also adds insurance charges, ordinary-income tax treatment on gains, and potential early-withdrawal penalties before age 59½ that a taxable mutual fund does not carry.

Are variable annuity withdrawals taxed as capital gains?

No. Earnings withdrawn from a variable annuity are taxed as ordinary income, not at long-term capital gains rates, even though the underlying subaccounts may hold stocks. This is an important contrast with holding those investments in a taxable account. Confirm details with the IRS or a tax professional.
