Social Security Break Even Calculator: 62 vs 67 vs 70
The Social Security break-even age is the age at which a later claim has paid you as much in total as an earlier one. Claiming early collects more checks; claiming later collects bigger ones, and the bigger checks catch up at one specific age. Live past it and waiting paid more; die before it and the early claim did. In the illustrative example below, someone whose benefit at full retirement age is $2,000 a month gets $1,400 by claiming at 62 or $2,480 by waiting to 70, and the later claim catches up at age 80.4. Between 62 and 67 the break-even is 78.7; between 67 and 70 it is 82.5.
That is the whole question of when to take Social Security, reduced to arithmetic. What decides it is how long you live, which cannot be looked up, plus a few things this post works through: whether the early checks would be saved, cost-of-living raises, and earnings if you keep working.
The rules the benefit follows
Your starting point is your primary insurance amount (PIA): the monthly benefit at full retirement age, shown on your statement at ssa.gov/myaccount. Claiming earlier or later moves it by fixed rules.
- Full retirement age is 67 for anyone born in 1960 or later. SSA’s page on the retirement age increase says it rises “until it reaches 67 for people born in 1960 and later.”
- Claiming early. The SSA Office of the Chief Actuary page “Benefit Reduction for Early Retirement” says: “The percentage reduction is 5/9 of 1% per month for the first 36 months and 5/12 of 1% for each additional month.” Claiming at 62 is 60 months early: the first 36 cost 20% and the other 24 cost 10%, a 30% cut.
- Waiting past full retirement age. SSA’s delayed retirement credit page lists “1943 or later 8.0% 2/3 of 1%” - 8% a year - and says “The benefit increase stops when you reach age 70.” The 36 months of credits from 67 to 70 add 24%.
So at 62 you get 70% of your PIA and at 70 you get 124%. On the example’s $2,000 PIA:
| Claim at | Share of PIA | Monthly benefit | A year |
|---|---|---|---|
| 62 | 70.0% | $1,400.00 | $16,800.00 |
| 63 | 75.0% | $1,500.00 | $18,000.00 |
| 64 | 80.0% | $1,600.00 | $19,200.00 |
| 65 | 86.7% | $1,733.33 | $20,800.00 |
| 66 | 93.3% | $1,866.67 | $22,400.00 |
| 67 | 100.0% | $2,000.00 | $24,000.00 |
| 68 | 108.0% | $2,160.00 | $25,920.00 |
| 69 | 116.0% | $2,320.00 | $27,840.00 |
| 70 | 124.0% | $2,480.00 | $29,760.00 |
The break-even formula
For an earlier claiming age A and a later age B:
collected before B = benefit at A x months from A to B
extra a month after = benefit at B - benefit at A
break-even age = B + (collected before B / extra a month) / 12
Which simplifies to (benefit at B x B - benefit at A x A) / (benefit at B - benefit at A).
For 62 against 70: claiming at 62 collects $1,400 for 96 months, $134,400, before the age-70 claim pays anything. After that the age-70 claim pays $1,080 a month more, and it takes about 10.4 years of that to make up the $134,400. That lands at 80.4.
62 vs 67 vs 70, every pair
| Earlier claim | Later claim | Collected before the later claim starts | Extra a month after | Break-even age |
|---|---|---|---|---|
| 62 ($1,400) | 67 ($2,000) | $84,000 | $600 | 78.7 |
| 67 ($2,000) | 70 ($2,480) | $72,000 | $480 | 82.5 |
| 62 ($1,400) | 70 ($2,480) | $134,400 | $1,080 | 80.4 |
The pairs do not line up the way a quick guess might suggest. Waiting from 62 to 67 breaks even soonest, at 78.7, because the early checks in those years are cut by 30%. Waiting from 67 to 70 breaks even latest, at 82.5: full checks given up for 36 months, recovered 8% a year at a time.
Here is the same thing as lifetime totals, by the age you live to. No interest, no raises, benefits paid every month from the claiming age:
| Lives to | Claim at 62 | Claim at 67 | Claim at 70 | Largest |
|---|---|---|---|---|
| 75 | $218,400 | $192,000 | $148,800 | 62 |
| 78 | $268,800 | $264,000 | $238,080 | 62 |
| 80 | $302,400 | $312,000 | $297,600 | 67 |
| 85 | $386,400 | $432,000 | $446,400 | 70 |
| 90 | $470,400 | $552,000 | $595,200 | 70 |
| 95 | $554,400 | $672,000 | $744,000 | 70 |
The winning column changes as the age at death rises: 62 for a short life, 67 in the middle, 70 for a long one. Living to 85, claiming at 70 collects $446,400 against $386,400 at 62. A Social Security break even calculator is really this table: it tells you where the lines cross, not which age you will reach.
The insight: the break-even age moves
The plain count above treats a dollar at 62 the same as a dollar at 80.4. Two things change that, in opposite directions.
If the early checks are saved. Suppose each early check is saved and earns 3% a year. By 70 the 96 checks have grown to $151,686, and the later claim’s extra $1,080 a month has to pay that down, interest still running. The break-even moves from 80.4 to 84.4, 4.1 years later. The 3% is an illustrative rate, not a forecast; the higher the return you could actually earn on the early checks, the later the break-even, and if those checks would simply be spent, the plain count is the honest one.
With cost-of-living raises. Benefits rise each year with the COLA. SSA’s COLA series lists “2025 2.8” - a 2.8% increase paid from January 2026. Raises are percentages, so they add more dollars to the bigger check. If the benefit rose 2.8% every year from 62 (the pack’s simple model, not SSA’s exact timing), the age-70 claim would start at $3,093.12 against the $1,400.00 first check at 62, and the break-even would come sooner, at 78.3. Future COLAs are unknown; 2.8% is a past figure used as an example.
So “the break-even age” is a range, and your own assumptions about saving and raises decide where in it you sit.
Working while claiming early
If you claim before full retirement age and keep working, the earnings test can hold checks back. SSA’s earnings test page lists the 2026 lower exempt amount as $24,480 and says: “We withhold $1 in benefits for every $2 of earnings in excess of the lower exempt amount.”
Illustrative example: claiming at 63 pays $1,500 a month. Earning $40,000 is $15,520 over the limit, so $7,760 is withheld - about 6 monthly checks. Those are not simply lost. The same SSA page: “Once you reach NRA, your monthly benefit will be increased permanently to account for the months in which benefits were withheld.” Here the benefit would be recalculated from $1,500 to $1,550 at full retirement age, because the 6 held-back months count as months not claimed. A higher limit applies in the year you reach full retirement age; the pack handles both.
If you are weighing early claiming against drawing on savings, the Coast FIRE calculator shows how a balance grows if you leave it alone, and the Roth vs traditional 401(k) post covers the tax rate side of retirement withdrawals.
How these were calculated
The share of PIA is counted month by month from full retirement age, using the reduction and credit rates quoted above; the results match SSA’s own table for people born 1960 or later (70% at 62, 124% at 70). Break-even ages use the formula above and are checked against a month-by-month running total. The saved-checks case compounds monthly and finds the month the saved pot is used up. The COLA case raises the benefit once a year from 62 and sums each year’s twelve checks. Whole-year claiming ages; SSA’s own rounding, payment timing, taxes on benefits, spousal and survivor benefits are not modeled here. The SSA figures were taken from ssa.gov pages on 2026-10-17.
Every figure on this page was computed twice - once by the code behind the calculator pack below, once by a separate implementation written from the SSA rules - and the two agree to the cent. The PIA, the return and the ages at death are illustrative, not anyone’s benefit and not a forecast. None of this is financial, legal or tax advice; your SSA statement and SSA itself are the authorities for your own benefit.
To run this on your own PIA - any two claiming ages, an exact claiming month, the spousal benefit, COLA raises and the earnings test - the pack below does it in linked spreadsheets with every formula visible.
