What's the best age to buy an annuity?

There's no universal "best age" to buy an annuity, but there are clearly better and worse windows depending on the type and your goal. The short answer: buy deferred-growth annuities (MYGAs) earlier to compound tax-deferred, and buy lifetime-income annuities (SPIAs/DIAs) when you actually need the income — most often between 65 and 75. This guide walks through the age dynamics, the real numbers, who each window is right for, the mortality-credit and laddering strategies, and the mistakes that quietly cost retirees the most.

The core age dynamic: growth vs. income

Every annuity decision splits along one line. For income annuities (a single-premium immediate annuity, or SPIA, and its deferred cousin, the DIA), waiting raises the monthly check because the insurer expects to pay you over fewer years. But you forgo the income you would have collected during the years you wait, so "later is bigger" isn't automatically "later is better."

For deferred-growth annuities (a multi-year guaranteed annuity, or MYGA, which works like a tax-deferred CD), earlier is the advantage — every extra year is another year of compounding inside the contract before you pay tax. The same calendar age can therefore be too early for one product and ideal for another.

Rough guidance by age band

Use these as starting points, not rules. The right answer depends on when you need income, your health, and how much guaranteed income you already have.

• 50s: A good window for deferred MYGA growth or for buying a future-income DIA cheaply. Usually too early to annuitize for income because payouts are low at these ages. (Life-contingent annuity payments are exempt from the 10% additional tax, but withdrawals of gains from a deferred contract before 59½ are not.)
• 60-65: Payouts run a bit lower than at 65. If the income can wait, a DIA or a MYGA often fits better (see the worked example below); if you need it now, buying is not a mistake.
• 65-75: The classic immediate/deferred income zone. Payouts become meaningful and longevity protection starts to matter. This is where most retirees who want guaranteed income should focus. A QLAC can also defer required minimum distributions while guaranteeing late-life income.
• 75-80: SPIA payouts are high and rising fast, but the income window is getting shorter.
• 80+: Very high payouts, but a shrinking horizon. Fit, underwriting limits, and refund options matter far more than squeezing out the top rate.

A female buyer's check runs about 4.2% lower at 65 and 7.1% lower at 80, reflecting longer life expectancy. Actual quotes vary by carrier, state, sex and payout option.

The real numbers: a worked example

Round, illustrative figures show the timing tradeoff better than any rule of thumb. Say you have $100,000 earmarked for guaranteed income, and a single-premium immediate annuity quotes roughly these life-only monthly payouts for a man:

Now weigh "wait or not." If you buy at 65 instead of 60, you give up five years of income — about $655 × 60 = $39,300 — to lift your check by $43 a month. Recovering that forgone $39,300 at the extra $43/month takes roughly $39,300 ÷ $43 ≈ 914 months, or about 76 years, before the higher check pulls ahead on cumulative dollars.

That number assumes the $100,000 sits idle for five years, and on its own the $43 bump never makes up five years of missed checks. Waiting pays only if the money keeps earning in the meantime. Parked in a 5-year MYGA at about the 5.59% average from our October table, it grows to roughly $131,000, which buys about $916 a month at 65 — $261 more than buying at 60. Then the forgone $39,300 comes back in about 150 months, around age 77 or 78. So waiting makes sense if you don't need the income yet, can keep the money earning safely until you buy, and expect to live past your late 70s. If you need the income at 60, buying then is not a mistake. The figures above are illustrative — interest rates, sex, joint-life options, and insurer all move them, so pull same-day quotes for your exact situation before deciding.

The mortality-credit curve

Annuity pricing is driven by life expectancy: the longer the insurer expects to pay you, the lower your monthly check. Mortality credits — the implicit "return" from the pool of buyers who die earlier than expected — accelerate after about age 70. Buying too early forfeits that acceleration; waiting too long compresses the income window.

The practical takeaway: the steepest part of the curve sits roughly between 70 and 80. That's why income annuities reward patience in a way that growth annuities don't — and why a buyer around 72 sits on the steepest part of the mortality-credit curve.

Who each window is right for — and who should skip it

Annuities are a decision, not a default. Match the product and the age to the job.

Good fits

• You'll likely live a long time (good health, long-lived family) and want guaranteed income you can't outlive — the longer you live, the better an income annuity pays off.
• You have a pension-sized gap between your essential expenses and your guaranteed income (Social Security plus any pension), and you want to plug it with a paycheck-like floor.
• You're prone to overspending or worry about managing a portfolio late in life — a fixed check removes the sequencing-of-returns and decision risk.

Reasons to skip or wait

• You haven't maximized Social Security. Delaying it is usually the better "annuity" first (more below).
• Health or family history points to shorter longevity. If you don't expect to reach the crossover age, a lifetime income annuity is a weak bet; consider a refund option or skip it.
• You need liquidity. Annuitized money is largely locked up. Don't annuitize funds you may need for emergencies, healthcare, or heirs.

Delay Social Security before you buy

For most retirees, the single best "annuity" is the one the government already offers. Each year you delay claiming past full retirement age up to 70 increases your benefit by about 8%, and that larger benefit is inflation-adjusted and backed by the federal government — features no private annuity matches at the same price. The mechanics are laid out in the SSA's delayed-retirement page.

Smart timing strategies

Ladder your purchases

Rather than buy one annuity at one age, ladder your purchases to hedge interest-rate timing and exploit the rising mortality-credit curve. Example: buy a $100k SPIA at 65, another $100k at 70, and a third at 75. Each layer locks in the rates and mortality credits of its purchase year, smoothing your income and cutting the risk of committing everything at the bottom of a rate cycle.

Use a QLAC for late-life "longevity insurance"

A Qualified Longevity Annuity Contract lets you use up to $210,000 of IRA money (the 2026 limit, indexed for inflation) to buy a deferred income annuity that can start as late as age 85. The amount in the QLAC is excluded from required minimum distribution calculations until payments begin, and because the income is so deeply deferred, each premium dollar buys far more income than an immediate annuity would. The textbook use is tail-risk insurance against living past 85 — see the IRS RMD rules.

Match the product to the timeline

1. Need income in 10+ years? A DIA or MYGA bought now captures today's rates and compounds before you draw.
2. Need income soon? A SPIA at the age you actually retire usually beats annuitizing early.
3. Worried only about very old age? A QLAC handles the tail cheaply without locking up all your money now.

Mistakes to avoid

The timing errors below quietly cost retirees the most.

• Annuitizing earlier than you need to. Income bought younger pays less per dollar for life. If you don't need the income yet and can keep the money earning safely, waiting a few years usually pays off by your late 70s, as the worked example shows.
• Buying before maximizing Social Security. You may pay a private insurer for income you could have gotten cheaper, and inflation-adjusted, from the SSA.
• Putting too much in. Annuitized money is illiquid. Keep a healthy reserve for emergencies, healthcare, and flexibility.
• Ignoring inflation. A level payout loses purchasing power over a long retirement; consider an inflation-adjusted option or keep growth assets alongside.
• Not shopping the rate. Payouts for the identical contract vary meaningfully by insurer and by day. Get multiple same-day quotes.

How to decide and what to do next

Let need, health, and Social Security timing — not a magic age — drive the call. A simple sequence:

1. Maximize Social Security (delay toward 70 if you can).
2. Size the gap between essential expenses and guaranteed income.
3. Pick the product for your timeline: MYGA/DIA earlier for growth or future income, SPIA when income starts, QLAC for the longevity tail.
4. Shop multiple insurers for same-day quotes and check claims-paying ratings.
5. Read the contract — surrender schedule, riders, refund options — before signing.
