What is a variable annuity? Subaccounts, fees, and riders in plain English.

What is a variable annuity, and how is it different from other annuities?

Every annuity is a contract that can turn money into income; the families differ in what happens to your money in the meantime. In a fixed or fixed indexed annuity, the insurer bears the market risk and credits interest by formula. In a RILA, you and the insurer split the market risk through buffers and floors. In a variable annuity, you carry the market risk yourself: your premium buys units of subaccounts, and the contract value is simply what those investments are worth, minus fees, on any given day.

One structural detail is genuinely reassuring and worth knowing. Subaccount assets are held in the insurer's separate account, legally walled off from the insurer's general creditors. Your investment can absolutely fall with the markets, but it is not sitting in the insurer's general pool the way a fixed annuity's reserves are. The promises that do depend on the insurer's own solvency are the guarantees you buy on top: riders, death benefits, and any annuitized income. Those are backed by the claims-paying ability of the issuing insurer, which is why insurer financial strength still matters here.

Variable annuities are securities sold by prospectus. They can lose value, including principal. Not FDIC-insured, not bank-guaranteed.

How do subaccounts actually work?

Subaccounts look and behave like mutual funds: stock portfolios, bond portfolios, balanced and target-style options, each with its own objective and its own expense ratio. You choose an allocation, the insurer buys units on your behalf, and your contract value tracks the unit values. Most contracts let you rebalance or exchange between subaccounts without triggering taxes, because everything inside the wrapper is tax-deferred; that in-contract flexibility is one of the product's genuine conveniences.

The differences from owning funds directly are the parts the brochure spends less time on. Each subaccount's expense ratio is charged in addition to the contract's insurance fees, so the same underlying portfolio costs more inside the annuity than outside it. The menu is limited to what the insurer offers, and menus change. And your returns compound net of the whole fee stack, which is why two investors holding identical markets can end retirement in very different places. That fee stack deserves its own section.

What does a variable annuity cost?

Variable annuity costs are layered, and each layer is real money every year, in up markets and down. The honest way to price one is to open the prospectus fee table and add the layers for the actual contract and riders you are considering. In plain English, the layers are these:

Stack the layers and the total annual cost of a variable annuity with a living-benefit rider commonly runs several percentage points a year, per the contract's own fee table — several times the cost of a plain index fund doing the same investing without the insurance. That is not automatically a bad deal. It is a price, and the only question that matters is whether the insurance you get is worth the growth you give up. Our guide to annuity fees walks the same logic across every product family, and surrender charges get their own plain-English treatment.

Fee structures vary widely by contract and share class. Illustrative descriptions only; verify every charge in the prospectus fee table before purchasing.

What are the optional riders — GLWB, GMIB, and death benefits?

Riders are optional insurance benefits bolted onto the contract for an annual fee, and they are usually the actual reason a variable annuity is being pitched. The most common living benefit today is the guaranteed lifetime withdrawal benefit (GLWB): for its fee, the insurer promises you can withdraw a set percentage of a benefit base each year for life, even if your account value later falls to zero. Older cousins include the GMIB, which guarantees a minimum income if you annuitize, and enhanced death benefits that lock in high-water marks for heirs.

One piece of fine print deserves plain English, because it is the single most misunderstood number in these contracts. The benefit base is a bookkeeping figure that can grow on a schedule the insurer sets, often faster than your real account value. The benefit base is not money. You cannot withdraw it or leave it to heirs; it exists only to size the rider's payments. And because rider fees are often charged as a percentage of the benefit base rather than the account value, the effective fee on the money you can actually access can be meaningfully higher than the stated rate. The same machinery, in its fixed indexed annuity form, is unpacked in our guides to guaranteed lifetime income and income riders.

Rider guarantees are backed by the claims-paying ability of the issuing insurer and are not FDIC-insured. Rider terms, fees, and availability vary by contract and state.

How does tax deferral work in a variable annuity?

Tax deferral is the wrapper's headline benefit, and it is real: inside the contract, dividends, interest, and rebalancing trigger no annual tax bill, which lets more money compound. The costs of that deferral arrive on the way out, and they deserve equal billing. Withdrawn gains are taxed as ordinary income, not at the lower capital gains rates your same investments would earn in a taxable account. On withdrawals from a non-qualified contract, gains come out first. Withdrawals before age 59½ may add a 10% federal penalty. And at death there is no step-up in basis: heirs owe ordinary income tax on the accumulated gain, where inherited stocks or funds would typically pass income-tax-free at the stepped-up value.

Two practical corollaries follow. First, a variable annuity inside an IRA earns no extra deferral, because the IRA is already tax-deferred; regulators including FINRA have flagged that pairing for years, and the only justification is a specific insurance feature you actually want. Second, if you already own a contract that no longer fits, a 1035 exchange can move it to a better one without triggering tax, though a new surrender schedule usually starts. The bigger picture of brackets, RMDs, and Social Security interactions lives in the retirement tax picture and how annuities are taxed. Consult a licensed tax advisor about your own situation.

How do variable annuities compare with RILAs and fixed indexed annuities?

The three products form a risk ladder, and the variable annuity stands on the top rung: the most market exposure, the most upside, and the most explicit fees. One rung down, the RILA trims both tails with buffers and caps. At the bottom, the fixed indexed annuity never passes index losses to you at all.

All guarantees in every column are backed by the claims-paying ability of the issuing insurer and are not FDIC-insured. Variable annuities and RILAs can lose principal. For the fixed families in depth, see types of annuities explained.

Are variable annuities worth it?

Here is the balanced answer. A variable annuity is worth its cost only when a specific insurance feature is doing a specific job in your plan that cheaper tools cannot do. For most people investing for growth, it is not: the fee stack commonly runs several times the cost of plain index funds, the tax deferral converts would-be capital gains into ordinary income, and heirs lose the step-up in basis. For a narrower group, it can be: someone who has maxed out their IRA and workplace plan and wants more tax-deferred space; someone who wants market participation but needs a contractual lifetime income floor an insurer stands behind; or someone whose plan genuinely fails without a check that continues no matter how long they live. The product is neither the scandal its critics describe nor the free lunch its illustrations imply. It is a bundle of prices, and the right question is which parts of the bundle you would willingly buy on their own.

One caution cuts the other way, and an honest page has to include it. If you already own an older variable annuity with a rich rider — some contracts issued years ago carry benefit terms insurers no longer offer — do not surrender it on a generic "annuities are bad" argument. Have the specific contract valued, including its rider, before making any move; the free-look period protects new buyers, but nothing un-surrenders an old contract. The self-check in is an annuity right for me and the twelve questions to ask any advisor both apply in full here.
