Should You Claim Social Security at 62, 67 or 70? The Break-Even Math
This is one of the few retirement decisions that is genuinely irreversible, worth six figures, and made by most people based on a feeling about whether the system will still be there.
The arithmetic is worth doing first.
Every figure below is a worked example on one assumed benefit. Yours comes from your own SSA statement.
The Three Numbers
Your benefit at full retirement age is called your primary insurance amount. Claim before it and it’s permanently reduced; claim after and it’s permanently increased.
With a full retirement age of 67, claiming at 62 reduces the benefit by 30%, and delaying past full retirement age earns delayed retirement credits of about 8% a year up to age 70, for a total increase of 24%.
Take a benefit of $2,400 a month at 67 — $28,800 a year.
| Claim at | Monthly | Annual | vs age 67 |
|---|---|---|---|
| 62 | $1,680 | $20,160 | −30% |
| 67 | $2,400 | $28,800 | — |
| 70 | $2,976 | $35,712 | +24% |
The spread between the earliest and latest option is $15,552 a year, every year, for life. That’s not a rounding error on a retirement plan — on a 25× basis it’s the equivalent of $388,800 of portfolio.
Full retirement age is 67 for people retiring now, but it has shifted by birth year over time. Check yours on your SSA statement rather than assuming, because every percentage above hangs off it.
The Break-Even Ages
Claiming early means more cheques, each smaller. Claiming late means fewer cheques, each larger. The break-even is where the cumulative totals cross.
62 versus 67. By the time you turn 67, the early claimer has collected five years at $20,160 = $100,800. From 67 onward the late claimer receives $8,640 a year more. $100,800 ÷ $8,640 = 11.7 years.
Break-even: age 78.7.
67 versus 70. By 70, the 67-claimer has collected three years at $28,800 = $86,400. From 70 onward the delayer receives $6,912 a year more. $86,400 ÷ $6,912 = 12.5 years.
Break-even: age 82.5.
62 versus 70. By 70, the early claimer has collected eight years at $20,160 = $161,280. From 70 onward the delayer receives $15,552 a year more. $161,280 ÷ $15,552 = 10.4 years.
Break-even: age 80.4.
| Comparison | Break-even age | Live shorter → | Live longer → |
|---|---|---|---|
| 62 vs 67 | 78.7 | 62 wins | 67 wins |
| 67 vs 70 | 82.5 | 67 wins | 70 wins |
| 62 vs 70 | 80.4 | 62 wins | 70 wins |
Those cluster in a narrow band around 79 to 82, which is not a coincidence — the reduction and credit schedules were designed to be roughly actuarially neutral for someone of average life expectancy. The system is not trying to trick you either way.
What the Break-Even Leaves Out
Break-even tables are the standard tool and they systematically mislead in three directions.
They ignore what the early money could earn. Claim at 62 and invest every payment at a 4% real return, and by 70 that $161,280 is closer to $186,000 — pushing the 62-vs-70 break-even out by roughly a year and a half. This only counts if you actually invest it rather than spend it, which most people who claim at 62 do not, because they claimed at 62 because they needed the money.
They ignore where the bridge money comes from. Delaying from 62 to 70 means funding eight years of spending from your portfolio instead. That’s $161,280 you don’t withdraw if you claim early — money that stays invested and compounding. Portfolio drawdown and benefit delay are two sides of one decision, and treating them separately is the most common error in this analysis.
They price a single life, not a couple’s. This is the big one. When one spouse dies, the survivor keeps the larger of the two benefits — not both. A higher earner who claims at 62 locks a 30% cut into the amount their surviving spouse will live on, possibly for twenty years. For couples, the higher earner delaying and the lower earner claiming earlier is a genuinely different calculation from the one in the table above, and it usually favours patience on the larger benefit.
The Cases That Are Clear
Claim early if: you have a health condition that meaningfully shortens life expectancy, you have no other assets and need the income now, or you’re the lower earner in a couple where the higher earner is delaying.
Delay if: you’re the higher earner in a couple, you have portfolio assets to bridge the gap, and you have no specific reason to expect a short retirement. The right frame here isn’t investment return, it’s insurance — you’re buying a larger, inflation-adjusted, guaranteed income stream that pays off precisely in the scenario where everything else has run out. Longevity is the risk retirement planning is worst at handling, and delayed Social Security is the cheapest hedge available.
Somewhere in between: full retirement age is the default for a reason. It’s the neutral choice, and choosing it deliberately is different from claiming at 62 because a form arrived.
One Thing to Watch Before Full Retirement Age
If you claim before full retirement age and keep working, the retirement earnings test temporarily withholds part of your benefit above an annual earnings threshold. The withheld amount isn’t lost — your benefit is recalculated upward at full retirement age to account for it — but the cash flow hit surprises people who claimed at 62 while still working part-time. If you’re planning to work past 62, check the current-year threshold before filing.
Putting It in the Plan
Social Security isn’t a standalone decision. It sets the guaranteed-income line that determines how much your portfolio has to produce — and a $15,552 swing in that line moves your portfolio target by roughly $388,800 at a 25× multiple.
The way to model it is a table with one column per claiming age: annual benefit, the resulting portfolio gap, the required portfolio, and the cumulative benefit collected by ages 75, 80, 85 and 90. Seeing all three columns at once makes the trade concrete in a way a single break-even age never does.

Frequently Asked Questions
How much less do you get if you claim Social Security at 62?
With a full retirement age of 67, claiming at 62 reduces the benefit by 30% permanently. On a $2,400 monthly benefit at full retirement age, that's $1,680 a month instead — $20,160 a year rather than $28,800. The reduction is not temporary and does not reset when you reach full retirement age; it applies for the rest of your life, and it carries through to a surviving spouse's benefit.
What is the break-even age for delaying Social Security to 70?
Against claiming at 67, the break-even is roughly age 82 and a half — before that you're behind, after that you're ahead. Against claiming at 62, delaying to 70 breaks even around age 80. These are simple cumulative-dollar break-evens on a $2,400 full-retirement-age benefit and ignore what you could have earned investing the early payments, which pushes the break-even later.
Is it worth delaying Social Security to 70?
It depends on health, whether you have a spouse, and where the money comes from in the meantime. Delaying is best understood as buying inflation-adjusted longevity insurance — you give up eight years of payments in exchange for a permanently 24% larger benefit that a long life makes very valuable. It's a poor trade if you have a serious health condition or no other assets to live on, and a strong one if you're the higher earner in a couple, because a surviving spouse inherits the larger benefit.
Does claiming early affect my spouse's benefit?
Yes, and this is the most consequential thing most couples miss. When one spouse dies, the survivor keeps the larger of the two benefits, not both. If the higher earner claims at 62 and takes a permanent 30% cut, that reduced amount is what the survivor lives on — potentially for decades. For couples, the higher earner delaying and the lower earner claiming earlier is a common strategy precisely because it protects the survivor benefit.
