A reader named Carol wrote to me last year, a few months before she retired from a hospital job she had held for 28 years. She had about $480,000 in her 401(k), a paid-off house, and a small pension. What kept her up at night was not the size of the number. It was a simpler fear: what if I live to 95 and the money runs out at 88? A salesperson had offered her "guaranteed income for life," and she wanted to know if it was real.
It is real. But it is also not the magic floor the glossy brochure implies. Annuities are one of the most oversold and misunderstood products in personal finance, partly because sellers often earn a fat commission, and partly because the contracts run to pages of fine print. Let me walk you through what they actually are.
What an annuity really is
Strip away the jargon and an annuity is a contract with an insurance company. You hand over a lump sum, and in exchange the company pays you a stream of income over time, often for the rest of your life, money you cannot outlive.
That last part is the whole point. Most retirement risk is not about earning the highest return. It is about longevity risk, the unglamorous danger of living longer than your savings last. Social Security handles some of this, since it pays until you die and adjusts for inflation, and an annuity buys more of that same guarantee with your own money. The insurer can promise it because it pools thousands of buyers: some die early, some live to 100, and the contract is priced around the average. You are sharing risk with a crowd, the way auto insurance does, just pointed at a happier outcome.
The main types, without the alphabet soup
A single premium immediate annuity (SPIA) is the simplest and cleanest: you pay once, and income starts within about a year. As a rough 2026 example, a 65-year-old man putting in $100,000 might receive around $600 to $660 a month for life. A woman the same age gets a bit less, because women live longer on average. These quotes move with interest rates.
A deferred income annuity works the same way, but you buy now and turn the income on later, say at 80. Because the insurer holds your money longer, the payouts can be surprisingly large. A fixed annuity, meanwhile, pays a set interest rate for a term, much like a bank CD, though it is backed by the insurer rather than FDIC insurance.
The two types that draw the most complaints are variable annuities and indexed annuities. They bundle market exposure with insurance features, layer on fees that can reach 3% or more a year, and lock your money up with surrender charges that might start at 7% and phase out over 7 to 10 years. They are not automatically bad, but they are where the high commissions live. Go slow.
A realistic example with real dollars
Say Carol takes $120,000 of her $480,000 and buys a SPIA at 65. She locks in roughly $700 a month, or $8,400 a year, for as long as she lives. Add her $1,900 Social Security check and her small pension, and her fixed bills are now covered by guaranteed income. That is the real benefit: not the return, but the freedom to stop checking her balance every time the market drops 400 points.
The other $360,000 stays invested for growth and flexibility. If you understand how compounding builds your nest egg over time, you can see why I rarely want a retiree to annuitize everything. The invested slice keeps pace with inflation and stays available for a new roof or a medical surprise. Here is a simplified comparison of putting that $120,000 to work three ways.
| Approach | Monthly income | Access to principal | Inflation protection |
|---|---|---|---|
| SPIA at 65 | Around $700, for life | None once purchased | Weak unless you buy a rider |
| Balanced portfolio | Varies, you choose | Full | Moderate to good |
| Savings or CDs | Modest, follows rates | Full | Poor |
None of these is the "right" one. They solve different fears, and the best mix depends on your situation.
The fees and fine print that quietly eat returns
With a plain SPIA, the cost is baked into the payout and fairly transparent. The trouble starts with the fancier products. Between the mortality and expense charge, administrative fees, optional riders, and the fees on underlying subaccounts, a variable annuity can quietly cost 2.5% to 3.5% a year, against perhaps 0.03% for a plain index fund. If you have read what the S&P 500 actually is, you know low-cost index funds exist precisely so you do not hand a third of your growth away.
Ask the agent directly: "How are you paid on this, and what is the total annual cost as a percentage?" A fee-only fiduciary answers without flinching. A commissioned salesperson often changes the subject. The answer tells you almost everything about whose interest the recommendation serves.
Common myths I hear over and over
The first myth is that an annuity is an investment that will beat the market. It will not, and is not designed to. You are buying certainty, not upside, and treating it like a growth vehicle is how people end up disappointed.
The second myth is that the guarantee is as ironclad as FDIC insurance. It is not. Payments are backed by the insurer's financial strength, then by your state guaranty association up to a state-specific limit. That is real protection, but the insurer's credit rating matters, so spreading a large purchase across two highly rated companies is reasonable.
The third myth is that you must annuitize a huge share of your savings. You almost never should. Covering essential bills with income, then investing the rest, is the approach I see work best. How much you need depends on your other guaranteed income, which is why looking at how much you should have saved by each age helps you size the decision.
Who annuities actually suit
After all that, you might think I dislike annuities. I do not. I dislike how they are sold. The product fits a specific person well: someone with a real gap between their guaranteed income and their fixed expenses, who worries about outliving their money, who lacks a generous pension, and who values a calm night's sleep over the last percentage point of return. Carol fit that profile. A 70-year-old with a large pension, or anyone young who needs liquidity or already covers their needs with a strategy like the 4% rule, often does not.
You do not have to choose all-in or all-out. A sensible structure is to annuitize just enough to cover essentials such as housing, food, utilities, and insurance, then keep the rest in a diversified, low-cost portfolio. Floor plus upside, not one or the other.
Before you sign anything, it is worth paying a fee-only financial advisor for an hour of flat-rate time. Someone who earns no commission on the sale can tell you whether the contract is fair, and that fee is tiny next to a six-figure, often irreversible decision.
Are annuities a good investment for everyone?
No, and anyone who says so is selling something. An annuity converts savings into guaranteed lifetime income, which suits people who fear outliving their money and lack other guaranteed income. It is a poor fit if you need liquidity, want to leave the principal to heirs, or already have your essential expenses covered.
What happens to my money if I die early?
With a plain lifetime annuity, payments usually stop and the insurer keeps the balance, which is why they pay so much to people who live long. If that worries you, you can add a period-certain or cash-refund feature that pays a beneficiary, though it lowers your monthly income.
How safe is the guarantee behind an annuity?
It rests on the insurer's financial strength, not on FDIC insurance, with a backstop from your state guaranty association up to a state-specific limit. Favor insurers with high independent ratings, and consider splitting a large purchase across two strong companies.
If you remember one thing, let it be this: an annuity is insurance against a long life, not a bet on a good market. Used in the right amount, by the right person, it buys a peace no spreadsheet captures. Used wrong, it just buys someone else a commission. Take your time, ask about the fees out loud, and let the decision fit your situation.
