Claim at 62 and collect smaller checks for longer; wait and collect larger checks for less time. The whole argument collapses into one number, the break-even age where the two paths have paid the same total, and everything turns on which side of it your own longevity lands. This calculator compares any two claiming ages, shows the monthly check each one produces in today's dollars, finds the exact age where the later claim catches up, and lets you add a real investment return to price what the early checks would have been worth in hand.
Every claiming-age argument you have ever heard is a bet on one unknown, your own date of death. Claim at 62 and you take 30 percent less per month but start collecting five years sooner. Claim at 67 and each check is 43 percent larger than the early one, but the first one arrives at 67. Somewhere in your late seventies the two strategies have delivered the same total money, and past that point every additional year of life is a year the early claimant wishes they had waited. The break-even age is where the insurance value of waiting and the cash value of starting cross.
At the page's defaults the crossing lands at about age 78 years 8 months. The table below shows the cumulative totals in today's dollars: the age-62 claimant is ahead by $73,188.96 at 70, still ahead by $30,964.56 at 75, falls behind for the first time just after 78, and is behind by $137,933.04 if both live to 95. Note what does not appear anywhere in this table: your benefit size. The claiming factors are fixed percentages of whatever your benefit is, so the break-even geometry is identical for a $1,000 check and a $4,000 check. What moves the answer is only which two ages you compare, and what the early money could earn.

Variables in plain terms. PIA is the primary insurance amount, your monthly benefit if claimed exactly at full retirement age; the default $2,345.80 matches a worker whose earnings history is mid-career professional, and you should replace it with the estimate from your own mySocialSecurity statement or the site's Social Security estimator. The factor f(a) is the actuarial adjustment SSA applies: for a full retirement age of 67, each of the first 36 months of early claiming costs 5/9 of 1 percent and each month beyond that costs 5/12 of 1 percent, while each month of delay past 67 earns 2/3 of 1 percent, or 8 percent per year. The cumulative line is deliberately arithmetic in today's dollars, because every check is indexed to the same COLA and inflation multiplies both columns identically.
PIA $2,345.80, comparing 62 against 67. The early check is $1,642.06 per month and starts five years sooner; the full check is $2,345.80. The early claimant banks $157,637.76 by age 70 while the late claimant has collected $84,448.80, a $73,188.96 lead. The monthly difference is $703.74, so the catch-up arithmetic is simple: the lead shrinks by $8,444.88 per year, and 73,188.96 divided by 8,444.88 takes about 8.7 years past age 70, landing at roughly 78 years 8 months. From that birthday onward, waiting was the better deal, and the gap widens by $8,444.88 every year both people remain alive.
The comparison ages matter more than most people expect, because the early-claiming reduction is front-loaded. Claiming at 62 against 67 breaks even at about 78.7, but waiting until 65 rather than 67 breaks even at about 80.0, and 67 against 70 breaks even around 82.5, because the delayed credits up to 70 are generous relative to the months given up. Comparing 62 directly against 70 pushes the crossing to about 80.4. The lesson inside the numbers: the steepest penalty, dollars of benefit per month surrendered, is in the earliest years, so the 62-to-64 stretch is where claiming costs the most per month given up.
The return input is the other lever, and it is the one that quietly changes the question. Money collected at 62 can be invested, and every year of compounded growth the early checks earn postpones the age at which waiting catches up. At a 2 percent real return the 62-versus-67 crossing stretches to about 81.0; at 4 percent it reaches about 85.0; at 6 percent, about 93.7; and at 8 percent the delayed claim never catches up within a normal lifetime. Be skeptical of your own input here. A retiree who needs the benefit to live on has no portfolio to invest, so the honest return is zero and the honest break-even is 78.7. The 4 percent answer only applies to someone who genuinely banks the early checks they do not spend, and sequence risk makes even that optimistic in practice.
Life expectancy is the final input, and the honest one is personal rather than statistical. The SSA's 2026 Trustees Report puts period life expectancy at 65 at about 18.2 additional years for men and 20.7 for women, so the average man reaches his mid-80s and the average woman nearly 87, both comfortably past the 78.7 crossing. The asymmetry still deserves respect: dying at 72 after claiming at 67 forfeits checks that are finite and easy to count, while reaching 95 after claiming at 62 means the shortfall compounds for decades at the exact age replacing it is hardest. The break-even age answers where the strategies tie; it does not tell you that tying is the right goal.
Because there are three different questions hiding under one label. A break-even in today's dollars asks when the larger delayed check has repaid, in real purchasing power, everything the early claim collected first; at this page's defaults that is about 78 years 8 months. A break-even in nominal dollars adds inflation to the later check's base, which can move the crossing point a year or more either way depending on the assumed COLA. And a break-even with opportunity cost asks what the early checks would have earned if invested, which stretches the answer dramatically: at a 4 percent real return the 62-versus-67 crossing moves from about 78.7 to about 85, and at 8 percent the delayed claim never catches up within a normal lifetime. Any calculator that shows you a single number without telling you which of these it computed is hiding the assumption that drives the whole answer.
For anyone with a full retirement age of 67, claiming early costs 5/9 of 1 percent of your primary insurance amount for each of the first 36 early months and 5/12 of 1 percent for each month beyond that. Claiming at 62 therefore means 60 early months: 36 times 5/9 plus 24 times 5/12 equals a 30 percent permanent reduction, so the check is 70 percent of the full amount. Waiting past full retirement age earns delayed retirement credits of 2/3 of 1 percent per month, or 8 percent per year, which compounds to 24 percent more by age 70. These factors are fixed by law and identical for everyone at the same full retirement age, so the break-even geometry in real dollars is also identical for everyone: it does not depend on how large your benefit is.
Not in the terms that matter. Social Security applies the same cost-of-living adjustment to every beneficiary's check each year, whether you claimed at 62 or 70, so both streams in this comparison are indexed identically and inflation cancels out. That is why this calculator works entirely in today's dollars: the 2026 COLA of 2.8 percent, or any other rate, scales both columns of the comparison by the same factors and leaves the real break-even age untouched. Where COLA does matter is in nominal-dollar comparisons, the kind that add up raw check amounts across decades. A nominal sum collected in year 25 is not comparable to a nominal sum collected in year 5, and calculators that mix the two without discounting can overstate the case for whichever age they favor. The honest habit is to compare in today's dollars and treat inflation as common to both paths.
It can delay the start of the checks, which changes the calculation. In 2026 the earnings test withholds $1 of benefits for every $2 earned above $24,480 in years before full retirement age, and $1 for every $3 above $65,160 in the year you reach it. Withheld benefits are not confiscated: at full retirement age, Social Security recomputes your payment upward to credit back the months benefits were withheld, which effectively converts some of the reduction into a later, larger check. But the cash flow you actually receive between 62 and full retirement age can be far smaller than the calculator's benefit figure if your earnings are high, so treat the early-claim column as the gross entitlement rather than the deposited amount. Wages after full retirement age never trigger the test.
A claiming age is partly a survivor-benefit decision, and the break-even math on this page does not capture that. When one spouse dies, the survivor steps up to the larger of the two checks being paid, and that larger check is permanently shaped by when the higher earner claimed. A worker who claims at 62 locks in a 30 percent reduction that continues in the survivor's check for as long as the survivor lives; waiting to 70 raises the survivor's floor by the full 24 percent of delayed credits. For many married couples the higher earner's delay functions as cheap life insurance for the surviving spouse, which is an argument for later claiming that a single-life break-even understates. Run the survivor and spousal pages alongside this one before deciding, and weigh family longevity history on both sides.
Start from the averages, then adjust honestly. The Social Security Administration's 2026 Trustees Report puts period life expectancy at 65 at about 18.2 additional years for men and 20.7 for women, which lands the average 65-year-old man's median death near 83 and the average woman's near 86. Against this page's default break-even of about 78.7 for claiming at 62 versus 67, a man at average longevity gains only modestly from waiting, while a woman at average longevity clears the break-even with several years to spare. Then adjust for what you know: personal health, family history of longevity, and access to healthcare all move your personal median. The deeper point is that the comparison is asymmetric. If you claim late and die early, the forfeited checks are finite and visible. If you claim early and live to 95, the shortfall compounds for decades precisely when you are least able to replace it, which is why treating the delay as insurance rather than an investment is the sounder frame.
