How to calculate your break-even age
Break-even math compares two streams of checks. Claiming early gives you a head start: every month before the later claim brings money the patient claimer never receives. Claiming later brings a bigger check, and each month the difference chips away at that head start. The break-even age is the point where the head start has been fully repaid.
To find it, multiply the early monthly benefit by the number of months between the two claiming ages. Divide that head start by the monthly difference between the two benefits. The answer is the number of months after the later claim needed to catch up; add it to the later claiming age.
Because the early-claiming reduction and delayed retirement credits are fixed percentages of your primary insurance amount, the result depends only on your full retirement age, not on the size of your benefit. Everyone with a full retirement age of 67 gets the same break-even ages. Count both streams at today’s prices: cost-of-living adjustments raise both checks by the same percentage, so they drop out of the comparison.
Break-even ages for common claiming choices
With a full retirement age of 67 and no investment return, claiming at 70 instead of 62 breaks even at about 80 years 4 months. Waiting from 62 to 67 breaks even at about 78 years 8 months, and waiting from 67 to 70 at about 82½.
After full retirement age, each extra year of waiting has a later break-even than the one before. You give up a larger check each year to earn the same 8% credit, so catching up takes longer: waiting from 67 to 68 breaks even at about 80½, while the final year, from 69 to 70, breaks even at about 84½.
The table also shows what happens when you account for what the money could earn. If early checks let you keep savings invested at a 2% or 3% return above inflation, every break-even moves roughly two to four years later. That is the main reason two careful analyses of the same benefits can reach different conclusions.
Your odds of living past the break-even age
A break-even age only means something next to how long you are likely to live. In SSA’s 2023 period life table, the one used in the 2026 Trustees Report, a 62-year-old man can expect about 20.3 more years and a woman about 23.1, pointing to the early-to-mid 80s. Both averages fall after the 62-versus-70 break-even of about 80.
The same table shows about 62% of 62-year-old men and 72% of 62-year-old women reaching 80. For a married couple who are both 62, the chance that at least one of them reaches 80 is about 89%, treating their lifespans as independent. That second figure matters most when the higher earner delays, because the survivor keeps the larger check.
Period tables apply a single year’s death rates to the rest of a life, with no future improvement, so they tend to understate how long people live. Your own health and family history matter more than any average. See longevity risk for why planning to an average age is itself a risk.
What the simple math leaves out
A break-even age compares raw totals of one person’s checks. That is a useful first cut, but it leaves out several things that decide real outcomes. Some make waiting look better and others make claiming early look better, so the answer is often a range of ages rather than a single number. It also compares two fixed ages, when in practice you can claim in any month from 62 to 70. The main factors:
- Investment returns. Money received early can stay invested or replace portfolio withdrawals. Discounting at a real return of 2% moves the 62-versus-70 break-even from about 80 to about 82¾.
- A spouse’s lifetime. A survivor benefit keeps the deceased worker’s delayed credits, so for the higher earner the payoff depends on the longer of two lives.
- Taxes. Up to 85% of benefits can be taxable, depending on provisional income. Waiting can open low-income years for Roth conversions, while larger benefits later can push more income into tax.
- Work. Claiming before full retirement age while earning over $24,480 in 2026 triggers the earnings test, which withholds benefits and shrinks the head start.
- Cash needs. If you need the income now and have few other resources, the break-even comparison matters less than paying the bills.
Break-even thinking vs. insurance thinking
The break-even frame treats claiming as a bet on your lifespan: claim early and win if you die young, wait and win if you live long. The two outcomes are not equally painful, though. If you die early, you will not need the money. If you live to 95, a check that is 77% larger than the age-62 amount, raised with prices every year, can decide whether your savings last. Delaying works much like buying an inflation-protected Annuity from the government, paid for with the benefits you skip.
Seen that way, the question shifts from which age maximizes expected total benefits to which choice keeps your plan secure across the ages you might reach and the markets you might face. That depends on your other income, your savings, your spouse and your spending, which is why many planners compare claiming ages inside a full retirement projection rather than on a break-even chart alone.
Illustrative numbers
Claiming at 62 vs. 70 with a $2,000 benefit at a full retirement age of 67
- Early benefit
- Monthly benefit at the earlier claiming age
- Later benefit
- Monthly benefit at the later claiming age
- Months of head start
- Months between the two claiming ages
This undiscounted version ignores taxes and investment returns; because COLAs raise both checks alike, it holds at today’s prices.
Benefit at 62 (70% of $2,000)$1,400 a month
Benefit at 70 (124% of $2,000)$2,480 a month
Head start from claiming at 6296 months × $1,400 = $134,400
Extra each month after 70$2,480 − $1,400 = $1,080
Months to catch up$134,400 ÷ $1,080 ≈ 124.4, about 10 years 4 months
Break-even ageAbout 80 years 4 months
If this person lives beyond about 80 years 4 months, claiming at 70 pays more in total; if not, claiming at 62 paid more. The $2,000 does not change the answer: any worker with a full retirement age of 67 gets the same break-even, because it rests only on the 70% and 124% ratios.

Break-even age in MoneyWhatIf
In MoneyWhatIf you can test the claiming question inside your whole plan. Change a Social Security card’s claiming age in a What-If and the projection runs again with the new age, carrying it through withdrawals, taxes and later balances, while the original plan is drawn dashed underneath. The year the two net-worth lines cross is, in effect, your plan’s own break-even. Lifespans are plan inputs, with 90 in a blank plan, so try a longer one too. The app compares scenarios rather than recommending a claiming age.
Common questions
Break-even age FAQs
What is the break-even age for Social Security at 62 vs. 67?
For anyone whose full retirement age is 67, about 78 years 8 months, before taxes and investment returns. Claiming at 62 pays 70% of the full benefit for five extra years. The full benefit at 67 is 30 percentage points larger and needs about 11⅔ years to make up the 60 payments it skipped. At a 2% real return, the break-even moves to about 81.
What is the break-even age for waiting until 70?
Compared with claiming at 67, waiting to 70 breaks even at about 82½; compared with claiming at 62, at about 80 years 4 months, assuming a full retirement age of 67 and no investment return. If the early checks would otherwise earn a 3% real return, those ages rise to about 86½ and 84⅓.
Does break-even analysis work for married couples?
Only partly. For the higher earner, the relevant lifespan is usually the longer of the two, because a surviving spouse can keep the larger benefit, delayed credits included. The chance that at least one of two 62-year-olds reaches 80 is about 89% in SSA’s period life table. Spousal benefits, by contrast, do not grow when the worker delays, so run the comparison for the household rather than each person alone.
Is it better to claim early and invest the money?
Only if the investments earn a solid return above inflation, and that return comes with market risk. Discounting at 2% real moves the 62-versus-70 break-even from about 80 to about 82¾; at 4%, to about 86½. Many people who claim early spend the checks rather than invest them, in which case the benefit mainly replaces portfolio withdrawals, and the fair comparison is what those withdrawals would have earned.
