When to claim Social Security: 62, 67 or 70, and why the break-even age is the wrong question
Claiming at 62 pays 70 percent, at 70 it pays 124 percent. The three break-even ages, why withheld benefits are not lost, and the survivor benefit nobody mentions.
Every guide to this question hands you a break-even age and lets you decide whether you will live that long. The number is usually somewhere around 80, stated with more confidence than it deserves.
The number is real. It is also three different numbers, it changes with the pair of ages you compare, and for a married couple it is not the question that matters most.
The short version: with a full retirement age of 67, claiming at 62 pays 70 percent of your full benefit for life and claiming at 70 pays 124 percent. That is a difference of 77 percent between the smallest and largest cheque you can arrange for yourself. The break-even sits in the late seventies to early eighties depending on the comparison, and if you are married, the higher earner’s claim age also sets a floor under the survivor’s income for the rest of their life.
What the three ages actually pay
Full retirement age is 67 for anyone born in 1960 or later. If you were born earlier it is 66 plus some months, and every percentage below shifts with it.
The reduction for claiming early is set by formula, not by table: five ninths of one percent for each of the first 36 months before full retirement age, and five twelfths of one percent for each month before that. Claiming at 62 with a full retirement age of 67 is 60 months early, so 36 months at five ninths gives 20 percent and the remaining 24 months at five twelfths gives 10 percent. Thirty percent off, for life.
Delaying works the other way at two thirds of one percent a month, which is the 8 percent a year you see quoted. Those credits stop dead at 70.
| Claim age | Monthly benefit | On a $2,000 full benefit |
|---|---|---|
| 62 | 70% | $1,400 |
| 63 | 75% | $1,500 |
| 64 | 80% | $1,600 |
| 65 | 86.7% | $1,733 |
| 66 | 93.3% | $1,867 |
| 67 (full) | 100% | $2,000 |
| 68 | 108% | $2,160 |
| 69 | 116% | $2,320 |
| 70 | 124% | $2,480 |
Two things are worth pausing on. The first is that the curve is not symmetrical: the first year of delay past 67 adds 8 points, while the last year before 62 costs only 5. The second is that nothing happens after 70. Every month you wait past your 70th birthday is a cheque you simply do not collect, and people do lose money this way while believing they are being patient.
The break-even, done honestly
The break-even is the age at which total benefits received, added up, stop favouring the earlier claim. Run it on nominal dollars, with no investment return and no COLA, using the percentages above.
62 against 67. By 67 the early claimer has banked 60 months at 70 percent, so 4,200 percentage-months in the bank. After 67 the later claimer gains 30 points a month. Divide and you need 140 months, which is 11 years 8 months past 67, so about age 78 years 8 months.
62 against 70. By 70 the early claimer has banked 96 months at 70 percent, or 6,720. After 70 the gap is 54 points a month. That is 124 months, 10 years 4 months past 70, so about age 80 years 5 months.
67 against 70. By 70 the full-retirement claimer has banked 36 months at 100, or 3,600. The gap is 24 points a month. That is 150 months, 12 years 6 months, so about age 82 years 6 months.
So the honest answer to “what is the break-even age” is: 78 and a half, 80 and a half, or 82 and a half, and you have to say which two ages you mean. A guide that gives one number has quietly picked a comparison for you.
Now the caveats, because this arithmetic is cleaner than life.
Investment returns push the break-even later. If you claim at 62 and genuinely invest the cheques rather than spend them, the early money compounds and the crossover moves out by years. If you claim at 62 because you need the money to live on, there is no portfolio effect and the simple arithmetic above is the right one. Most guides model the first case and most readers are in the second.
Taxes cut both ways and are too personal to generalise. Social Security is taxed on a formula that depends on your other income, so a year with large withdrawals can make more of your benefit taxable.
COLA does not change the crossover much, because the adjustment is proportional. A 2 percent rise lifts the small cheque and the large one by 2 percent each, and the ratio between them is untouched.
The thing that is not on the break-even chart
If you are married, your claim age is not only about you.
When one spouse dies, the survivor keeps the larger of the two benefits, not both. So whichever of you has the bigger benefit is, in effect, setting the income floor for whichever of you lives longer. Claim early as the higher earner and that floor is 30 percent lower for as long as the survivor lives. Delay, and it is 24 percent higher.
This changes the shape of the decision. On a single life, delaying is a bet: you win if you live past the crossover. For a couple, delaying the higher earner’s claim is closer to buying insurance, and what it insures is the long tail where one person is alive, alone, and old. The relevant life expectancy is not yours, it is the longer of two, which is always further out than either alone.
The lower earner’s claim age matters much less for the same reason, which is why the common pattern of the lower earner claiming early and the higher earner waiting is not a contradiction. It is two different jobs.
Working while claiming is not the trap it looks like
If you claim before full retirement age and keep working, part of your benefit is withheld. In 2026 you can earn $24,480 with nothing withheld, and above that one dollar of benefit is held back for every two dollars of earnings. In the calendar year you reach full retirement age the limit jumps to $65,160, only earnings in the months before your birthday month count, and the ratio softens to one dollar withheld for every three earned. From the month you reach full retirement age the test disappears and you can earn anything.
Here is the part that is almost always reported wrongly. Withheld benefits are not confiscated. At full retirement age your benefit is recalculated upward to credit the months in which benefits were withheld, so over a normal lifespan you get the money back. The earnings test is a cash flow deferral dressed up as a penalty, and people take real decisions, like turning down work, on the strength of the dressing.
What it does genuinely cost you is liquidity in the years you are working, and that is a reason to think about it. It is not a reason to believe the money is gone.
The Medicare surcharge is set two years before you see it
One more connection, because it catches people who are doing everything else right.
The income-related surcharge on Medicare Part B is set from your tax return two years earlier. Your income at 63 decides your premium at 65; your income at 65 decides it at 67. If your plan for the gap before Social Security starts is to live off a traditional IRA or to run Roth conversions while your taxable income is low, those are the years that set the premium. Doing the conversions is often still right. Doing them without looking at the brackets is how a sensible plan produces a surprise bill two years later.
The same income number also governs health insurance subsidies if you retire before 65, where the consequences in 2026 are harsher than they have been in years. That is a separate piece of arithmetic and we wrote it up in health insurance before Medicare.
What to actually write down
The decision does not need a projection out to two decimal places. It needs four things on one page.
Your benefit at all three ages, from your own record. Not a rule of thumb. Your Social Security statement gives the estimate at 62, at full retirement age and at 70, and the gap between them is the only version of this table that applies to you.
Both benefits, if you are married, and which is larger. The larger one is the survivor’s floor. That single fact reorders most couples’ thinking.
What you will live on in the gap. If the answer is a traditional account, note the balance you expect to draw each year, because that number is also your Medicare surcharge input and your health insurance subsidy input.
The age at which you stop being indifferent. Not the break-even, your own. For most people the real question is not “will I live to 80” but “how much do I mind being 85 with a smaller cheque”, and that is a question about character rather than arithmetic.
Our retirement planner holds all four in one place: the benefit at 62, full retirement age and 70 with the break-even worked out, a survivor note, the drawdown order across taxable, traditional and Roth money, and the Medicare timeline running alongside. It runs on your own machine with no account and nothing sent anywhere, which for a file containing every account balance you own is the point.
Frequently asked questions
How much less do I get if I claim Social Security at 62?
If your full retirement age is 67, claiming at 62 pays 70 percent of your full benefit for life. The reduction is five ninths of one percent for each of the first 36 months you claim early and five twelfths of one percent for each month beyond that, which works out to 30 percent across the full five years.
How much more do I get if I wait until 70?
Two thirds of one percent for every month you delay past full retirement age, which is 8 percent a year. With a full retirement age of 67 that is 24 percent, so age 70 pays 124 percent of your full benefit. Delayed credits stop at 70, so waiting past your 70th birthday gains nothing and costs you every cheque you did not take.
What is the break-even age for Social Security?
There is no single one, because it depends which two ages you are comparing. With a full retirement age of 67 and ignoring investment returns, 62 against 67 breaks even at about 78 years 8 months, 62 against 70 at about 80 years 5 months, and 67 against 70 at about 82 years 6 months. Those three numbers answer three different questions and are often quoted as if they were one.
Do I lose my benefits if I work while claiming early?
No, they are withheld and then given back. Under full retirement age for all of 2026 you can earn $24,480 before anything is withheld, and above that one dollar of benefit is held back for every two dollars of earnings. When you reach full retirement age your monthly benefit is permanently recalculated upward to account for the months that were withheld. It is a deferral, not a penalty, which is the opposite of how it is usually described.
Does waiting to claim mean I miss out on the cost of living increases?
No. Cost of living adjustments are applied to your benefit record every year from the year you turn 62 onwards, whether or not you have claimed. You do not forfeit a single COLA by waiting, so the usual worry that delaying freezes your benefit at today's prices is unfounded.
Does my claim age affect what my spouse gets after I die?
Yes, and this is the part most comparisons leave out. A surviving spouse steps up to the higher of the two benefits, so whichever of you earned more sets the floor for whoever lives longer. Claiming early as the higher earner cuts that survivor benefit permanently, and delaying raises it. Judged on one life a delay is a bet on your own longevity; for a couple it is closer to insurance on the longer of two lives.
Can claiming age affect my Medicare premium?
Not directly, but the income you live on in the gap can. The Part B income-related surcharge is set from your tax return two years earlier, so your income at 63 decides what you pay at 65. If you are draining a traditional account or converting to a Roth to cover the years before Social Security starts, that is the year to look at the surcharge brackets.
Is there any reason to claim at 62 if I can afford to wait?
Several, and they are not foolish. A health condition that genuinely shortens life expectancy, no other money to live on, or a need to stop drawing down a portfolio during a bad market. What makes a 62 claim expensive is doing it by default, without ever running the number, and then finding out at 80 that the gap has been compounding for eighteen years.
