- Payout rates rise with age because the insurer expects to pay for fewer years — the increase is mortality, not a better deal.
- The right question is not your age but whether you have an income gap, and whether the money funding it has a job it is doing better elsewhere.
- For immediate income, waiting raises the payout rate but forfeits the payments you would have collected — those two forces cross at a computable point.
- For deferred income, buying earlier buys more mortality credits, which is why a QLAC purchased at 65 for income at 85 is priced so favourably.
- Interest rates move payouts as much as age does in the short run, and unlike your age they can move in either direction.
Search this and you get a number: sixty to seventy. That range is real — it is where most purchases happen and where most of them make sense. It is also the least useful thing anyone can tell you, because age is not what decides this. Age is a proxy for three conditions, and the proxy is what people end up optimising when they wait.
Why payout rates rise with age — and why that isn't the argument it looks like
A 75-year-old buying an immediate annuity gets a materially higher payout rate than a 65-year-old paying the same premium. That looks like a reward for patience. It is not.
The insurer prices from a mortality table. It expects to pay the 75-year-old for fewer years, so it can pay more per year from the same money. The higher rate is compensation for a shorter expected payout period, not a better bargain. Understanding that one sentence prevents the most common error on this topic: treating "rates go up if I wait" as a reason to wait, when what actually goes up is the rate per year of a shorter expected stream.
The immediate income trade, computed
For income starting now, waiting a year does two things at once. It raises the payout rate you will eventually receive. It also forfeits twelve months of payments you would have collected, permanently — they are not deferred, they are gone.
Those two forces cross. The higher rate has to make up the entire year of missed payments before waiting has broken even, and because the annual rate improvement is small relative to a full year of income, the crossing point sits years out — frequently a decade or more. If you have an income gap now, waiting for a better rate usually loses, and it loses quietly, because the payments you never received do not appear on any statement.
The arithmetic is worth running with your own quotes rather than taking on faith. Two SPIA quotes at your current age and one year older, the difference in annual income, divided into the twelve payments you would forgo, gives you the number of years to break even.
The deferred income trade runs the opposite way
For income starting later, buying earlier wins, and it wins by more than most people expect.
A deferred income annuity purchased at 65 for income beginning at 85 is priced with twenty years of mortality standing between purchase and first payment. Some buyers will not reach 85, and their premiums fund the survivors' payments — the mortality credits that no portfolio can replicate. Buy the same income at 75 for an 85 start and you have only ten years of that effect working for you, so the premium is far higher.
This is why the honest answer to "what age" splits by product. For immediate income, later is priced better but costs you the payments in between. For deferred income, earlier is priced better and costs you nothing but commitment. Anyone giving one answer for both is answering half the question.
The variable nobody mentions: interest rates
Payout rates move with prevailing interest rates as well as with your age, and in the short run the rate environment can matter more than a year of aging. The difference is direction: your age only goes one way, and rates go both.
The practical implication is not to time the market — nobody can — but to recognise that "I'll wait for a better rate" is a bet on two variables, only one of which is predictable. It also argues for laddering: buying income in tranches across several years averages the rate environment the same way a bond ladder does, and it lets you stage income against a gap that opens gradually.
The three conditions that actually decide it
Do you have an income gap? Essential expenses, minus Social Security, minus any pension. If the number is zero or negative, no age is the right age — you do not need this product, and our income floor guide explains why that is a legitimate conclusion rather than a failure to find the right contract.
Does the money have a better job? Premium committed to an annuity is premium not available for anything else, and inside a surrender period it is not readily available at all. Money that is your emergency reserve, or that has a known claim on it inside the surrender term, has a job already.
Do you want a contractual number or an expected one? This is temperament, and it is a legitimate input. Some people sleep better with a guaranteed figure that is lower than the likely outcome. Others find committing principal intolerable at any payout rate. Neither is wrong, and pretending the decision is purely mathematical ignores the reason most people are asking in the first place.
How the answer changes by decade
Fifties. Narrow case. Deferred income locked cheaply, or tax deferral after other accounts are full. Against it: long surrender periods, decades of inflation ahead of a level payment, and an income gap that is genuinely hard to see this far out.
Sixties. Where most purchases belong. The gap becomes visible, Social Security timing is a live decision, and deferrals can be short. The interaction with delaying Social Security matters here more than the annuity choice itself — each year of delay past full retirement age buys inflation-adjusted income at a price no carrier matches, so that lever comes first.
Seventies. The best payout rates in the market, and a strong case for anyone with an income gap and family longevity. Watch the structure rather than the rate: shorter deferrals, deliberate death-benefit election, and surrender periods that should not outlast your planning horizon.
Eighties. Payout rates are at their highest and the product is still legitimate for closing a genuine gap. Underwriting and issue-age limits narrow the field, and the case for a period-certain or refund element strengthens considerably.
The version of this question worth asking
Not "what is the best age," but: do I have a gap, is this the money to close it, and does this contract close it better than the alternatives at today's rates? Those have answers you can compute this week. The age question has an answer that will be true whenever you ask it and useful in none of those weeks.
