Social Security Break-Even Calculator
Claiming at 62 pays you less every month but pays you sooner. This finds the age at which the bigger cheque overtakes the head start — on your own benefit amount, with inflation adjustments and, if you want, the return you would earn by investing the early payments.
What the break-even age actually means
Social Security is designed to be roughly actuarially fair: claim early and you get a smaller payment for more months; claim late and you get a larger payment for fewer. The break-even age is the point where the two cumulative totals cross. Before it, the early claimer is ahead. After it, the person who waited is ahead — and stays ahead, permanently and by a widening margin.
On a typical benefit with no investment assumption, waiting from 62 to 70 breaks even at around age 81, and waiting from 62 to full retirement age breaks even at around age 79. Assume you invest every early payment at 5% a year and those move out to roughly age 89 and age 88.
Why the break-even age is the wrong question for most people
Break-even analysis quietly assumes the goal is to collect the most dollars. For most retirees the real goal is different: not running out of money if you live a long time. Social Security is the only inflation-adjusted income you cannot outlive, so delaying it is best understood as buying longevity insurance, not as an investment with a payback period.
That reframing changes the answer. If you die at 75, claiming at 62 wins — but you are not there to care. If you live to 95, delaying wins by six figures, and that is precisely the scenario in which running short of money would have hurt.
What the benefit is at each age
| Claiming age | Share of your full benefit | On a $2,000 full benefit |
|---|---|---|
| 62 | 70% | $1,400/mo |
| 63 | 75% | $1,500/mo |
| 64 | 80% | $1,600/mo |
| 65 | 86.7% | $1,733/mo |
| 66 | 93.3% | $1,867/mo |
| 67 (full retirement age) | 100% | $2,000/mo |
| 68 | 108% | $2,160/mo |
| 69 | 116% | $2,320/mo |
| 70 | 124% | $2,480/mo |
Full retirement age is 67 for anyone born in 1960 or later. If you were born earlier it is 66 and some months, and every percentage above shifts accordingly.
When claiming early is genuinely right
- Poor health or a shortened life expectancy. The break-even maths simply does not get reached.
- You need the money now. Claiming at 62 to avoid selling investments in a down market, or to avoid debt, is a real and rational reason.
- You are the lower earner in a couple. The standard strategy is for the lower earner to claim early and the higher earner to delay to 70, because the higher benefit becomes the survivor benefit for whichever spouse lives longer.
- You have no other savings and no way to bridge. Delaying only works if something funds the gap.
When delaying is worth it
- You are the higher earner in a couple. Delaying raises both your benefit and the survivor benefit — it pays off across two lifetimes, not one.
- You are in good health with family longevity. The odds of reaching the break-even age are what matter, not the average.
- You have savings to bridge the gap. Spending $X of portfolio to buy a permanently higher, inflation-linked, government-backed income is usually a better trade than the portfolio itself offers. See the bridge calculator.
- You want lower taxes later. The years between retiring and claiming are usually your lowest-income years, which makes them the best window for Roth conversions.
The 8% figure, precisely
Delayed retirement credits are two-thirds of 1% per month — 8% a year — from full retirement age to 70, and they stop dead at 70. There is never a reason to delay past your 70th birthday. Going the other way, the reduction is five-ninths of 1% per month for the first 36 months before full retirement age, then five-twelfths of 1% for each month beyond that, which is why claiming at 62 with a full retirement age of 67 costs exactly 30%.
Frequently asked questions
What is the break-even age for Social Security?
Comparing age 62 with age 70 and ignoring investment returns, the crossover usually falls around age 80–81. Add an assumption that you invest the early payments and it moves into the mid-to-late 80s. Enter your own benefit above for the exact age on your numbers.
Is it better to take Social Security at 62 or 67?
Claiming at 62 pays 70% of your full benefit; waiting to 67 pays 100%. The cumulative crossover is usually around age 78–79. If you expect to live beyond that, are the higher earner in a couple, or have savings to bridge the gap, waiting is generally better.
Does waiting to 70 really increase my benefit by 24%?
Yes, if your full retirement age is 67. Delayed retirement credits add 8% a year from full retirement age to 70, so three years of delay adds 24% — permanently, and before annual cost-of-living increases compound on top of the larger amount.
Should both spouses delay Social Security?
Usually not. The common approach is for the lower earner to claim earlier for cash flow and the higher earner to delay to 70, because the larger of the two benefits continues as the survivor benefit after the first death. Delaying the higher benefit protects both lifetimes.
Does the break-even calculation account for inflation?
Yes. Benefits are increased by the cost-of-living adjustment you enter each year, and because COLAs are a percentage, they compound on a larger base for someone who delayed — which is one reason delaying wins by more than the headline 24%.
