Social Security claiming calculator
Claiming at 62, 67, or 70 changes your monthly check and the age at which waiting pays off. This finds the break-even age — and moves it once you invest the early checks.
Enter your benefit at full retirement age (67 for anyone born in 1960 or later). The calculator applies the SSA reduction and delayed-credit schedule to find your check at 62, 67, and 70, then the break-even ages between them.

How the math works
Social Security starts from one number: your benefit at full retirement age, called the primary insurance amount (PIA). For anyone born in 1960 or later, full retirement age is 67. Claiming earlier cuts that number; claiming later adds to it. The schedule is fixed by statute, not by your bank.
Claim late: benefit = PIA × (1 + 2/3% × m), credits capped at age 70
Here m is the number of months you claim away from full retirement age. Run the schedule for an FRA of 67 and it works out to 70% of the PIA at 62, 100% at 67, and 124% at 70 — a spread of 54 percentage points on the same earnings record.
The break-even age is the point where the bigger delayed checks catch up on total dollars collected. The early claimant banks a smaller check for longer; the late claimant collects a larger one, but starts years behind. The formula for the crossover is a head start divided by the monthly gap.
Worked example
Take a worker with a full-retirement-age benefit of $2,800 a month, deciding among 62, 67, and 70. Run the SSA schedule and the checks come out to $1,960 at 62, $2,800 at 67, and $3,472 at 70.
Compare claiming at 62 against waiting to 70. The early claimant collects $1,960 a month for the eight years from 62 to 70 — a head start of $188,160 before the late claimant sees a cent. After 70 the late claimant collects $1,512 more each month. Dividing the head start by that gap, the delayed benefit overtakes the early one at about age 80. The 62-vs-67 crossover lands earlier, at roughly age 78 years 8 months; the 67-vs-70 crossover lands later, at 82 years 6 months.
So the honest summary is: if the worker lives past 80, delaying to 70 wins on total dollars. If they don't, claiming early does. Every consumer calculator gets this far. The two things below are where most stop, and where the decision actually lives.
When this calculator is wrong
The break-even ages above assume the checks are spent the month they arrive. That is the assumption almost every Social Security calculator makes silently, and it is the one that moves the answer most.
- It ignores what the early checks could earn. If you claim at 62 and invest the money instead of spending it, the head start compounds. At a 2.0% real return — the long-run real return on a 10-year Treasury — the 62-vs-70 break-even slides several years past 80. At a stock-like 7.0% real return it can move past any plausible lifespan, which flips the case toward claiming early. Set the "real return" field above to your own number and watch the break-even move.
- It treats life expectancy as a single number. It isn't one. Per the Social Security Administration's period life table, roughly 25% of 65-year-old women are still alive at 90, and about 10% at 95. Delaying to 70 is not a bet that you'll beat the average — it's insurance against landing in that tail and outliving your money. Planning to a fixed "average" age understates the risk that matters.
- It assumes you claim in a vacuum. Spousal and survivor benefits, taxes on benefits, and the earnings test if you keep working before full retirement age all bend the result. A married couple's optimal claim is a joint decision, because the higher earner's delayed benefit also raises the survivor's check.
The framing that survives all of this: the 4% rule and most retirement calculators understate longevity risk. The default age assumption on many of them is 85 or 90, but a 1-in-10 chance of reaching 95 is not a rounding error. Delaying Social Security is one of the few ways to buy inflation-adjusted income that lasts as long as you do. The exception is if you have a genuine reason to expect a shorter life, or you need the cash at 62 to avoid selling investments in a down market — then the early check earns its keep.
What to do with the result
Start with your own life-expectancy read and your own return assumption, not the calculator's defaults. If you'd spend the checks and have no strong reason to expect a short retirement, the math leans toward delaying: every year you wait past 67 adds 8% to a benefit that is inflation-protected and lasts for life. If you'd invest the early checks at a real return above roughly 4%, or you need the income at 62, the early claim holds up.
The practical next step is to pull your actual benefit estimate from ssa.gov — it uses your real earnings record — and drop the full-retirement-age figure into the field above. Then run it twice: once at a 0% return, once at the return you'd actually earn. The gap between those two break-even ages is the size of the decision.
Common questions
- What is the break-even age for Social Security?
- It's the age at which the larger checks from claiming later add up to more total dollars than the smaller checks from claiming earlier. For a full retirement age of 67, claiming at 62 versus 70 breaks even around age 80, spending the checks. Live past it and waiting wins; die before it and claiming early wins.
- How much does waiting from 67 to 70 add to my benefit?
- 8% per year, or 24% over the three years, through delayed-retirement credits. A $2,800 benefit at 67 becomes $3,472 at 70. Credits stop accruing at 70, so there is no reason to wait past it.
- Is it better to take Social Security at 62 or 67?
- It depends on how long you expect to collect and whether you'd invest the early money. Claiming at 62 pays 70% of the full benefit but starts five years sooner. On spent checks the two break even around age 78 years 8 months. Investing the early checks pushes that later.
- Does claiming early make sense if I invest the money?
- Sometimes. Investing the early checks compounds the head start and moves the break-even age later — past 80 at a 2.0% real return, and potentially past any realistic lifespan at a 7.0% real return. If you'll actually invest rather than spend, run the calculator with your real return in the field above.
- What if I'm married?
- The higher earner's decision also sets the survivor benefit, so a delayed claim by the higher earner protects the spouse who lives longer. That usually strengthens the case for the higher earner to wait, independent of their own break-even age.
