Social Security break-even calculator
Enter your full benefit and birth year, see the totals and the break-even age.
Find your full-retirement-age benefit in your Social Security statement at ssa.gov. The amount and the rates are example inputs. The early start must be 62 up to your full retirement age and the late start from it up to 70. Use whole or fractional years such as 66.5.
What the number means
Claiming Social Security earlier gives you a smaller check for more months; claiming later gives a larger check for fewer months. The break-even age is where the two totals meet. Before it, the early claimant has collected more; after it, the late claimant has. The calculator compares three starts side by side: an early one (62 by default), your full retirement age and a late one (70 by default), and shows the cumulative dollars at ages 70, 75, 80, 85, 90 and 95, with the largest total in bold. To see your full retirement age and the percentage for any month, use the Social Security calculator.
Worked example
Born in 1965, so full retirement age is 67 years; full benefit $2,000 a month. Start at 62: $1,400 a month. Start at 67: $2,000. Start at 70: $2,480. By age 80 the totals are $302,400, $312,000 and $297,600, and by age 90 they are $470,400, $552,000 and $595,200. The 62-versus-67 break-even is 78 years 8 months, 67 versus 70 is 82 years 6 months, and 62 versus 70 is 80 years 5 months.
Someone born in 1957 has a full retirement age of 66 years 6 months, so claiming at 62 pays 72.50% and 70 pays 128.00% of the full benefit, and the 62-versus-70 break-even is 80 years 6 months.
What is the break-even age for claiming Social Security?
It is the age at which the total you would have collected by waiting catches up with the total from claiming sooner. Take a full benefit of $2,000 a month and a birth year of 1965, so full retirement age is 67. Claiming at 62 pays $1,400 a month (70% of the full benefit), at 67 $2,000, and at 70 $2,480 (124%). With no yearly increases and no discounting, waiting from 62 to 67 pays off at 78 years 8 months, waiting from 67 to 70 at 82 years 6 months, and 62 versus 70 at 80 years 5 months. If you live past those ages, the larger monthly check has collected more in total. These are example numbers, not predictions.
How are the early and delayed amounts calculated?
The Social Security Administration reduces a benefit by 5/9 of 1% for each month you claim before full retirement age, up to 36 months, and by 5/12 of 1% for each further month. Someone with a full retirement age of 67 who claims at 62 (60 months) gets 36 × 5/9% + 24 × 5/12% = 30% less. Waiting past full retirement age earns delayed retirement credits of 2/3 of 1% a month, which is 8% a year, for people born in 1943 or later, and the credits stop at age 70. So 36 months of delay gives 24% more: 124% of the full benefit at 70. The calculator adds up each month's payment from the month you start; the break-even is the first month in which the late claimant's total is at least as large.
What is my full retirement age?
It depends on the year of birth: 66 for 1943 through 1954, then 66 and 2 months for 1955, 66 and 4 months for 1956, 66 and 6 months for 1957, 66 and 8 months for 1958, 66 and 10 months for 1959, and 67 for 1960 and later (SSA's age reduction page). Those born on January 1 count as born in the previous year. The calculator handles birth years 1943 to 2008; rules for earlier birth years differ. Because full retirement age is the 100% point, a later one means a bigger cut at 62: 25% for people born 1943 to 1954, 30% for 1960 and later.
What if benefits rise each year?
Retirees' benefits get a cost-of-living adjustment, which SSA set at 2.8% for 2026. Enter an expected yearly increase in the form and the calculator raises every claimant's benefit by that percent each year from age 62, in steps, so the early claimant also gets the increases. With 2.5% the example break-evens move to 76 years 9 months (62 vs 67), 80 years 7 months (67 vs 70) and 78 years 6 months (62 vs 70). Use 0 to read everything in today's dollars. Future increases are not known, so this is an assumption of yours.
What does discounting do?
A dollar received at 85 is worth less to you today than a dollar at 65, and the discount rate expresses that. At a yearly rate of 3% the example's 62-versus-70 break-even moves from 80 years 5 months to 84 years 5 months, because later payments count for less. A discount rate is a judgment about what you could earn on money you receive sooner or how much you value early income; the default of 0 is the plain "total dollars collected" view.
Is a bigger check always better?
No. The break-even is a statement about arithmetic, not about whether you will live that long or need the money earlier. Poor health, a short family history, a need to stop working at 62 or a spouse who will rely on your record are all legitimate reasons to claim early, and a larger benefit can matter if you are the higher earner in a couple because the survivor benefit follows it. This calculator ignores spousal and survivor benefits, taxes and the earnings test, so use it as one input and check your own record at ssa.gov.
How does this differ from the Social Security calculator?
The Social Security calculator on this site shows your full retirement age and the percent of your benefit at each claiming age. This page goes a step further: it adds up what each choice pays over time, in dollars, and finds the age where waiting wins. Use the first to look up the percentage and this one to compare the totals.
Common mistakes
The classic one is to treat the break-even as a forecast of when you will die. It is a threshold: if you expect to live beyond it, waiting wins on total dollars, but the result says nothing about health or about the value of money earlier in life. The second is to use a benefit estimate for age 62 as the full benefit: the figure the form wants is the benefit at full retirement age, the amount SSA shows for that age on your statement. The third is to forget that, for a married couple, the higher earner's choice also sets the survivor's check, which this simple comparison leaves out. Finally, working while collecting before full retirement age can temporarily withhold benefits under the earnings test; in 2026 SSA's exempt amount was $24,480 a year below full retirement age.
Limits of this method
The model adds monthly payments from the month you start and applies a single yearly increase that you enter, in whole yearly steps from age 62. Real increases vary, and SSA says that if you start before 70 some of the delayed credits are applied only the following January, so the break-even age can differ from SSA's own figure by a few months. Benefits can also be taxed, and Medicare premiums can be deducted from the check. Only birth years 1943 to 2008 are supported: the delayed credit differs for earlier years. For an official figure use your Social Security statement and the SSA calculators.
