Annuities in Retirement: When They Make Sense (and When They Don’t)

What an Annuity Actually Is

Strip away the marketing and an annuity is a simple trade: you hand an insurance company a sum of money, and in exchange they promise to pay you back over time, usually as a stream of income. That’s it. Everything else, the riders, the bonuses, the “guaranteed growth” language, is dressed up on top of that basic exchange.

The reason annuities exist at all is that they solve one specific problem: the fear of outliving your money. No other financial product transfers that risk to someone else the way an annuity does. A stock portfolio can run out. A bond ladder can run out. An annuity, if structured correctly, cannot, because the insurance company is contractually obligated to keep paying you as long as you’re alive.

That’s the whole value proposition. Everything else attached to an annuity is either a variation on that theme or a distraction from it.

The Four Types You’ll Actually Encounter

Immediate Annuities

You give the insurer a lump sum, and payments start right away, typically within a month. These are the simplest and usually the cheapest to understand. You know exactly what you’re getting: a fixed monthly check for life, or for a set period.

Deferred Fixed Annuities

You put money in now, it grows at a set interest rate, and you turn on the income stream later, often years down the road. These function a lot like a CD with a longer time horizon and a different tax treatment. Growth is predictable and modest.

Variable Annuities

Your money is invested in mutual-fund-like subaccounts, so the value can go up or down with the market. These carry the highest fees of the four types, often stacking mortality charges, administrative fees, and fund expenses on top of each other. They also tend to carry the highest sales commissions, which is worth noting since commission size often correlates with how hard a product gets pushed.

Indexed Annuities

These promise growth tied to a market index, like the S&P 500, but with a cap on how much you can gain and a floor that protects you from losses. The pitch sounds like “stock market upside with none of the downside.” In practice, the caps, participation rates, and spread fees usually mean you capture a fraction of actual index gains, and the formulas for how your return gets calculated can be genuinely hard to parse even for people who read financial contracts for a living.

When an Annuity Actually Helps

There are a handful of situations where an annuity is a legitimately good tool, not a sales trick.

• You have no pension and worry about longevity. If you’re 65, in reasonably good health, and have family history suggesting you might live into your nineties, converting a portion of savings into guaranteed lifetime income protects against the specific risk of living too long and running dry.
• You want to cover baseline expenses with certainty. A common approach is to use an annuity to cover fixed costs, housing, utilities, groceries, so that your remaining portfolio can be invested more aggressively for growth without the anxiety of needing it to cover rent next month.
• You’re bad at not touching your savings. Some people know themselves well enough to admit that if the money is liquid, they’ll spend it faster than planned. Locking a portion into an income stream removes that temptation entirely.
• You want to eliminate one specific risk, not chase returns. An annuity is insurance, not an investment. If you’re buying it to protect against longevity risk, it’s doing its job. If you’re buying it hoping to beat the market, you’ve misunderstood the product.

When an Annuity Is a Mistake

The reverse list is just as important.

• You already have solid guaranteed income. If Social Security and a pension already cover your fixed expenses, adding an annuity on top often just ties up money you didn’t need to lock away.
• You need liquidity. Most annuities charge steep surrender fees, often 7 percent or more in the early years, for pulling money out before an agreed schedule. If there’s a real chance you’ll need a large sum for a medical event, a move, or to help family, that money shouldn’t go into an annuity.
• The fees are stacked and opaque. If you can’t get a straight answer on total annual cost, mortality and expense charges, rider fees, fund fees, walk away. A product that resists a plain explanation is a product designed to be sold, not chosen.
• You’re being sold urgency. “This rate is only available this week” or “sign today to lock in the bonus” are pressure tactics, not honest product features. Insurance contracts don’t need to be rushed.

Questions to Ask Before You Sign Anything

Whoever is presenting the annuity should be able to answer these clearly and without hedging:

1. What is the total annual fee, including every rider and charge, expressed as a single percentage?
2. What happens to my money if I die in year three? Does my family get anything back, or does the insurer keep it?
3. What is the surrender schedule, and what percentage would I lose if I needed the full amount back in year one, three, or five?
4. How much commission are you earning on this sale?
5. Can you show me, in dollars, what I’d have after 10 years under a reasonable growth assumption, after all fees?

If the answers are vague, or the person shifts the conversation back to the guarantee without addressing the cost, treat that as information. A good product survives specific questions. A bad one depends on you not asking them.

A Simple Way to Decide

Before you consider any annuity, write down your fixed monthly expenses in retirement: housing, food, utilities, insurance, medications. Then compare that number to your guaranteed income from Social Security and any pension.

If there’s a gap, an annuity might reasonably fill it. If there isn’t, you likely don’t need one, no matter how compelling the pitch sounds. This single calculation cuts through most of the sales noise, because it forces the conversation back to what annuities are actually for: guaranteeing that your basic needs get met no matter how long you live, not maximizing returns or chasing a bonus rate.

Annuities aren’t inherently good or bad. They’re a tool built for one job. The mistake most retirees make isn’t buying an annuity, it’s buying one they didn’t need, at a cost they didn’t understand, from someone whose incentive wasn’t fully aligned with theirs.
