Say your Social Security benefit at full retirement age comes to $2,000 a month. Claim it the day you turn 62 and that check drops to $1,400 for life. Wait until 70 and the same benefit grows to $2,480. That's a gap of more than $1,000 a month, for the rest of your life, decided entirely by when you sign the paperwork.
Most people turning 62 this year don't run that comparison. They claim close to the birthday because the check is available and the need feels real, and nobody at the Social Security office sits them down to walk through what the decision actually costs over twenty or thirty years. The average retired worker is pulling in about $2,071 a month right now, and the difference between claiming early and claiming late can be worth tens of thousands of dollars over a normal lifespan.
This doesn't have one right answer. It depends on your health, your other income, whether you're married, and whether you're still working. But it is something you can actually calculate, and most people never do.
What claiming at 62 actually costs you
Your full retirement age, the point where you get 100% of your benefit, is 67 if you were born in 1960 or later. Claim at 62 instead and Social Security cuts your check by roughly 30%, and that reduction is permanent. It doesn't get corrected later, it doesn't reset, and it follows you for every check you receive for the rest of your life.
The math behind that number isn't arbitrary. Social Security shaves five-ninths of 1% off your benefit for each of the first 36 months you claim before full retirement age, then five-twelfths of 1% for every month beyond that. Stack up 60 months of early claiming, which is what happens if you go from 62 to 67, and you land at almost exactly 30% off. It's a formula built to even out over an average lifespan, not to punish you, but it still means a permanently smaller check if you don't live to the average.
What waiting until 70 actually gets you
Delay past full retirement age and the math flips in your favor. For every year you wait, your benefit grows by 8%, all the way up to age 70. At 70, someone with a full retirement age of 67 is collecting 124% of their full benefit, the maximum the formula allows. Waiting past 70 buys you nothing more, so if you haven't filed by then, file immediately.
One detail that surprises people: you don't lose out on inflation adjustments by waiting. Cost of living increases apply to your benefit starting the year you turn 62, whether or not you've actually claimed yet, so a delayed benefit still gets every COLA bump along the way. The idea that waiting means missing years of inflation protection is a myth.
It helps to think of delaying as buying a bigger, guaranteed, inflation-adjusted paycheck with your own patience. There's no CD or bond on the market that reliably pays out an extra 8% a year just for waiting, and Social Security does exactly that, for anyone healthy enough to make it worth the wait.
The break-even age most people never calculate
Here's the concept that actually settles this argument: the break-even age. It's the point where the bigger checks from waiting catch up to and pass the head start you got from claiming early. Before that age, claiming early wins on total dollars received. After it, waiting wins, and keeps winning for every year you live past it.
For claiming at 62 versus waiting for full retirement age, the break-even typically lands around 78 and a half. For full retirement age versus waiting all the way to 70, it's closer to 82 and a half. Comparing 62 directly against 70, most people land somewhere in the low 80s. Live past your break-even age and the delayed claim was the better financial move. Die before it and the early claim paid off instead. Nobody knows their own death date in advance, which is exactly why this is a bet, not a guarantee, in either direction.
Your health and family history change the math
If you're in solid health and your parents lived into their late 80s or 90s, the odds favor waiting. You're more likely to clear the break-even age and come out ahead with the larger check. The CDC's most recent numbers back that up in general terms: someone who reaches 65 today can expect to live to about 85, which is well past every break-even age described above. If you're managing a serious health condition, or your family has a pattern of shorter lifespans, claiming earlier and locking in income while you can use it may make more sense than betting on a break-even point you might not reach.
This isn't a call to be morbid about your own mortality. It's a call to be honest about it. A financial advisor or even a frank conversation with your doctor about your general health outlook is more useful here than any online calculator, because a national average doesn't know your family history, your diagnoses, or your daily habits, and you do.
What you'll live on between 62 and 70
Waiting until 70 sounds great on paper until you ask the obvious question: what pays the bills for those eight years? If you've got a pension, a paid-off house, retirement savings you're comfortable drawing down, or a part-time income stream, bridging the gap is realistic. If Social Security is your main source of income the moment you stop working, waiting eight years to claim it isn't a plan, it's a hardship.
Common bridge strategies include drawing from a 401(k) or IRA for a few years before benefits start, working part time to cover basic expenses, or using taxable savings and only tapping retirement accounts once Social Security kicks in. Some retirees use a reverse mortgage or downsize their home to free up cash rather than touch investments during the bridge years. None of these are free options, and each one comes with its own trade-offs, but they're worth pricing out before you assume delaying is off the table.
Some people split the difference and claim at full retirement age instead of pushing all the way to 70. You still get 100% of your benefit with no early reduction, and you don't need eight years of bridge income, just five. It's a reasonable middle path if neither extreme fits your finances.
If you're married, this isn't only your decision
Social Security lets a widow or widower step into whichever benefit is higher: their own, or a survivor benefit based on what their spouse was collecting. And a survivor benefit carries over any delayed retirement credits the deceased spouse had earned. That means if the higher earner in a marriage delays claiming until 70, the surviving spouse could eventually inherit that larger, delayed-credit benefit for the rest of their own life.
For couples, the general rule of thumb is that the higher earner should delay as long as financially possible, since that claim eventually becomes the survivor's income floor, while the lower earner has more flexibility to claim earlier if the household needs cash sooner. A spouse who never worked, or worked very little, can also claim a spousal benefit worth up to half of the other spouse's full retirement age amount, separate from any survivor benefit that kicks in later. This is a household decision, not two separate individual ones, and it's worth working through together rather than each spouse claiming in isolation.
Watch the earnings test if you're still working
If you claim before full retirement age and keep working, Social Security can temporarily withhold part of your benefit if you earn too much. In 2026, if you're under full retirement age for the entire year, the limit is $24,480, and Social Security withholds $1 in benefits for every $2 you earn above that. In the calendar year you actually reach full retirement age, the limit jumps to $65,160 for earnings before your birthday month, with $1 withheld per $3 over. Once you hit full retirement age, the earnings test disappears completely and you can earn any amount without losing a dollar of benefits.
The withheld money isn't gone forever. Social Security recalculates your benefit at full retirement age and credits you for the months it withheld, so your check goes up afterward to make up the difference over time. Still, if you're claiming at 62 and plan to keep working a job that pays well above the limit, you may end up getting very little of your benefit for years, which makes claiming early a much weaker move than the sticker number suggests.
Get your real numbers before you decide
Every example above uses round numbers because your actual benefit depends entirely on your own earnings record. The only way to make this decision properly is to pull your real figures. Log into your my Social Security account and look up your personal estimate at 62, at full retirement age, and at 70. Social Security's online calculators will show all three side by side.
Once you have your actual numbers, run your own break-even math using them instead of the examples here, then weigh that number against your health, your family's longevity, your marital situation, and how you'd cover your bills if you waited. Factor in taxes too, since up to 85% of your benefit can be taxable depending on your other income, which can shift the real dollar gap between claiming ages more than people expect. That combination, not the calculator alone, is what should drive a decision this permanent.
There's no version of this choice you get to remake later. Run your own numbers before you lock one in.
