Social Security Break-Even Calculator
Decide when to start Social Security by finding your break-even age: the age at which waiting for bigger checks overtakes the total you would have collected by claiming early. Enter the monthly benefit shown on your Social Security statement for your full retirement age (67), then the two ages you are weighing, such as 62 against 70. The calculator applies the percentages set in law (a benefit reduced to 70 percent at 62, or increased to 124 percent at 70) and shows each monthly amount, the break-even age, and the total each choice collects by the age you expect to live to. Your full-retirement benefit is your own figure from the SSA; the reduction and credit percentages are the official statutory rates.
Figure basis: Reduction and credit rates: official SSA (statutory)With a $2,000 full-retirement benefit, claiming at 62 pays $1,400.00 a month and claiming at 70 pays $2,480.00. They break even at 80 years 4 months: to age 85, delaying collects $60,000.00 more.

How the break-even age is calculated
Each claiming age has an official factor applied to your full-retirement benefit. Before 67 the benefit is reduced by 5/9 of one percent for each of the first 36 months early and 5/12 of one percent for each month beyond that; after 67 it grows by 2/3 of one percent a month (8 percent a year) up to age 70:
monthly benefit = full benefit x age factor
age factor: 62 = 70%, 65 = 86.67%, 67 = 100%, 68 = 108%, 70 = 124%
break-even age = (benefit_late x age_late - benefit_early x age_early) / (benefit_late - benefit_early)
Worked example
A $2,000 full-retirement benefit, comparing age 62 with age 70:
- At 62: $2,000 x 70% = $1,400.00 a month
- At 70: $2,000 x 124% = $2,480.00 a month
- Break-even = ($2,480 x 70 - $1,400 x 62) / ($2,480 - $1,400) = 80.37, about 80 years 4 months
- By age 85: claiming at 62 collects $1,400 x 23 x 12 = $386,400.00; claiming at 70 collects $2,480 x 15 x 12 = $446,400.00
- Living to 85, delaying is ahead by $60,000.00.
Why break-even is a starting point, not the answer
The break-even age is a clean number and a useful gut check: for the common 62-versus-70 comparison it lands around age 80 to 81 almost regardless of the benefit amount, because both sides scale with the same full-retirement figure. If your honest view of your own longevity is well short of the break-even age, claiming early keeps more total dollars in your hands; if you have a family history of long life and good health, delaying is effectively cheap longevity insurance that pays a bigger, inflation-adjusted check for as long as you live.
But three things the break-even calculation leaves out often tip the decision. First, survivor benefits: when the higher earner in a couple delays, the larger benefit is what a surviving spouse can step up to, so delaying can protect the person left behind far beyond the individual break-even. Second, taxes and the rest of your portfolio: claiming early can let tax-deferred accounts keep growing, or force you to sell investments in a down market, depending on your situation. Third, the option value of the money itself: benefits taken at 62 can be invested, and if you earn a strong return the break-even age moves later.
Use this tool to see the raw trade-off, then weigh it against your health, your spouse, and your other income. For most people in good health with a spouse to protect, delaying the higher earner's benefit toward 70 is the stronger default, but it is a decision about your whole household, not just a date on a chart.
Social Security break-even: frequently asked questions
What is the Social Security break-even age?
It is the age at which the larger checks from claiming later have added up to the same total as the smaller checks from claiming earlier. Before the break-even age, the person who claimed early is ahead on total dollars received; after it, the person who waited pulls ahead and stays ahead for life. If you expect to live past the break-even age, delaying usually pays more overall.
How much does claiming early or late change my benefit?
The percentages are set by law. With a full retirement age of 67 (everyone born in 1960 or later), claiming at 62 permanently cuts your benefit to 70 percent, and each year you wait past 67 adds 8 percent, up to 124 percent at age 70. So a $2,000 full benefit becomes $1,400 at 62 or $2,480 at 70. There is no gain from waiting beyond age 70.
Does this calculator account for cost-of-living raises or taxes?
No, and that keeps the break-even comparison clean. Annual cost-of-living adjustments apply to both the early and the delayed benefit, so they raise both sides and barely move the break-even age. Income tax on benefits and whether you could invest the early payments do matter for a full decision, so treat the break-even age as the starting point, not the whole answer.
If I might not live long, should I always claim at 62?
Not necessarily. Break-even math favours early claiming if your own life expectancy is short, but Social Security is also longevity insurance and can provide a survivor benefit for a spouse. A higher earner who delays locks in a larger check that a surviving spouse can step up to, which can matter more than the individual break-even age. Consider household longevity, not just your own.

- Delayed retirement credits (2/3 of one percent per month, 8 percent a year to age 70): SSA, delayed retirement credits.
- Your full-retirement benefit figure comes from your own SSA statement or estimator; the percentages above are statutory.
