What is a variable annuity? Sub-accounts, fees, and living benefits
Variable annuities invest in mutual-fund-like sub-accounts with optional guaranteed-income riders. Here's the trade-off math.
A variable annuity is one of the few annuity types where you can lose principal to the market — your money goes into investment sub-accounts that rise and fall, and it tends to carry the highest fees in the category. That combination means it's right for far fewer people than it's sold to. This guide explains how a variable annuity actually works, breaks down the full fee stack with real numbers, shows the trade-off math against a plain index portfolio, and spells out the narrow situations where it earns its keep.
How a variable annuity works
You allocate your premium among sub-accounts — mutual-fund-like portfolios of stocks, bonds, or balanced strategies. The account value moves with those investments, and all growth compounds tax-deferred until you withdraw it. There is no annual contribution cap the way there is on an IRA, which is part of the appeal for high earners who have run out of other tax-advantaged space.
A variable annuity has two phases. During the accumulation phase, your money grows (or shrinks) with the sub-accounts. During the payout phase, you can annuitize the contract into a stream of income, take systematic withdrawals, or cash out. Optional living-benefit riders can guarantee a minimum income or a protected "benefit base" for withdrawals, for an extra annual fee — even if the market tanks your actual account value.
Critically, a variable annuity is regulated as a security, not just an insurance product, because your money is genuinely invested. That means you receive a prospectus, and both the SEC and FINRA publish prospectus-based primers and investor alerts on these contracts. Always read the prospectus — that is where the fees and surrender schedule live. Variable annuities can be sold only by reps who hold a securities license (FINRA-registered) in addition to an insurance license. The licensed specialists we match readers with are insurance agents and may not hold one, so ask, and check any rep on FINRA BrokerCheck.
The four moving parts
A variable annuity is built from four layers, each with its own cost and benefit. Understanding which layer pays for which feature is how you spot the bad contracts — and how you compare two offers that look superficially similar.
| Layer | What it does | Typical annual cost |
|---|---|---|
| M&E (mortality & expense) | Insurance + admin overhead | 0.85%–1.50% |
| Sub-account fees | Mutual-fund expense ratios | 0.30%–1.50% |
| Living-benefit rider | Income or accumulation guarantee | 0.80%–1.50% |
| Death-benefit rider | Enhanced legacy floor | 0.20%–0.60% |
On top of these recurring layers sits the surrender charge — a one-time penalty for exiting early. It commonly starts around 7% of the amount withdrawn and steps down by roughly a point per year over a six-to-ten-year period. That schedule is why a variable annuity is a long-term commitment, not a parking spot for money you might need soon.
The honest, all-in cost
A fully loaded variable annuity — M&E plus sub-account fees plus a living-benefit rider plus a death-benefit rider — typically runs 3.0%–4.5% annually. That is a steep drag, but it is buying real contractual guarantees that most consumers cannot reproduce in a brokerage account. The question is always whether those guarantees are worth the fee for your situation.
Compare that to a low-cost index portfolio you can build in an IRA or taxable brokerage account, where total costs of 0.05%–0.20% are routine. The gap between paying 0.10% and paying 3.5% is not a rounding error — over decades, it is the difference between keeping your growth and handing most of it to the insurer.
The trade-off math: a worked example
Numbers make the fee drag concrete. Say you invest $100,000 and earn a 7% gross return every year for 20 years, and you compare two paths.
- Low-cost index portfolio at 0.15% all-in: your net return is about 6.85%. After 20 years, $100,000 grows to roughly $376,000.
- Loaded variable annuity at 3.0% all-in: your net return is about 4.0%. After 20 years, the same $100,000 grows to roughly $219,000.
That is a gap of about $157,000 — money the fee stack consumed. The tax-deferral advantage of the annuity does not come close to bridging it, especially since annuity withdrawals are taxed as ordinary income while the brokerage account's long-term gains can qualify for lower capital-gains rates.
Now flip it. Suppose you buy a low-cost variable annuity at 1.25% all-in instead — net return about 5.75%, growing $100,000 to roughly $306,000. The gap versus the index portfolio shrinks to about $70,000. But 1.25% all-in usually buys a plain contract with no living-benefit rider. Adding an income guarantee (0.80%–1.50% a year on its own) pushes the all-in cost above 2%, so price the guarantee separately before deciding it is worth the gap. The lesson: the cost layer you choose matters more than the product category.
Pros and cons
A variable annuity is a decision, not a default, so weigh both sides explicitly.
| Pros | Cons |
|---|---|
| Unlimited tax-deferred growth, no contribution cap | Highest fees in the annuity category (often 3%+ all-in) |
| Optional guaranteed-income and death-benefit riders | Real market risk — you can lose principal |
| Full market participation through sub-accounts | Earnings taxed as ordinary income, not capital gains |
| Creditor protection in some states | Surrender charges lock you in for 6–10 years |
| Can convert to lifetime income later | 10% IRS penalty on gains withdrawn before 59½ |
Who it (rarely) fits — and who should skip it
A variable annuity makes sense for a narrow profile: a high earner who has already maxed a 401(k) and IRA, wants additional tax-deferred investment growth, will hold it long term, and specifically values a living-benefit guarantee — and who buys a low-cost version. Outside that profile, simpler tools usually win.
- You've maxed all tax-advantaged accounts and want continued tax-deferral on after-tax money.
- You want market-linked growth with a contractual income floor that you can't engineer with a portfolio alone.
- You're in the 32%+ bracket today but expect a much lower bracket in retirement — the tax-deferral arbitrage gets more compelling at higher brackets.
- You have a beneficiary you want to leave the contract to and the death-benefit "step-up" rider is meaningful.
You should skip it if you haven't yet filled your 401(k) match, IRA, or HSA; if you might need the money within the surrender period; if you're in a low tax bracket where deferral does little; or if you simply want growth, where a low-cost index fund does the same job for a fraction of the cost. For most accumulation needs, an index-fund IRA wins.
Mistakes to avoid
Even buyers who genuinely fit the profile lose money to avoidable errors. The most common ones cluster around cost, timing, and taxes.
- Ignoring the combined fee. A 1% M&E "sounds" cheap until you add the fund, living-benefit, and death-benefit layers. Insist on one all-in number.
- Holding a variable annuity inside an IRA for the tax benefit. An IRA is already tax-deferred, so you're paying annuity fees for a feature you already have — usually a poor deal.
- Withdrawing before 59½. Gains are hit with ordinary income tax plus a 10% IRS penalty; the IRS treats annuity earnings as taxable income on withdrawal.
- Surrendering early. Cashing out during the surrender period can cost 5%–7% of the balance on top of taxes.
- Chasing a "free" 1035 exchange. Swapping contracts can restart the surrender clock and pay a fresh commission — only do it if the new contract is clearly cheaper or better.
How to evaluate one before you sign
If you've decided a variable annuity might fit, run a disciplined check rather than trusting the sales illustration. Treat it the way you'd treat any major financial purchase.
- Get the all-in cost in writing — M&E, sub-account, and every rider, as one combined percentage.
- Read the surrender schedule in the prospectus and confirm you can hold past it without needing the money.
- Verify the rider mechanics — whether the guaranteed "benefit base" is what you can actually withdraw, or just a notional figure used to calculate income.
- Check the insurer's financial strength rating, since the guarantee is only as good as the company backing it.
- Run a side-by-side illustration against a low-cost taxable or IRA index portfolio over your real time horizon.
