You can start Social Security retirement benefits as early as 62 or as late as 70. Every month you wait raises the check, and the higher amount lasts for the rest of your life. Every month you wait is also a month with no check. That’s the whole trade-off, and the right answer depends mostly on how long you expect to live, whether you’re married, and whether you need the money now.
What the ages mean
Your benefit is based on a number the Social Security Administration calls your primary insurance amount. That’s what you get if you claim at your full retirement age. For anyone born in 1960 or later, full retirement age is 67.
Claim earlier and the check is permanently reduced. At 62, with a full retirement age of 67, the reduction is 30%. Claim later and you earn delayed retirement credits of 8% for each year past full retirement age, up to age 70. There is no benefit to waiting past 70.
So if your full-retirement-age benefit is $2,000 a month, claiming at 62 gives you about $1,400, and waiting until 70 gives you about $2,480. Both figures would also get the yearly cost-of-living adjustments, which we’ll leave out here to keep the arithmetic simple.
Running the break-even
The person who claims at 62 gets a five-year head start. By 67 they have collected 60 checks of $1,400, which is $84,000. The person who waits to 67 then collects $600 more per month. It takes 140 months, a little under 12 years, to make up the $84,000. That lands at about age 78 and 8 months.
Comparing 67 with 70 works the same way. By 70, the 67-claimer has collected 36 checks of $2,000, or $72,000. The 70-claimer gets $480 more per month, which takes 150 months, or 12.5 years, to close. That’s around age 82 and a half.
If you live past those ages, waiting paid off. If you don’t, claiming earlier did. This ignores taxes, investment returns on early checks, and inflation adjustments, so treat the ages as rough. But the shape holds: waiting tends to win if you live into your 80s.
Why longevity cuts the other way than people think
People often say they’ll claim early because they might not live long. That’s a fair reason if you have a serious health condition. But the risk that hurts most in retirement is living a long time and running short of money, not dying early with unused benefits. A bigger check that adjusts for inflation and lasts as long as you do is a form of insurance against that. A 62-year-old who claims early to “get theirs” and then lives to 94 has locked in the smallest possible check for 32 years.
Married couples have a second reason to wait
When one spouse dies, the surviving spouse can generally keep the larger of the two benefits. That means the higher earner’s claiming age affects not just their own checks but potentially the survivor’s checks for years afterward.
A common approach is for the lower earner to claim earlier, which brings some income into the household, while the higher earner waits as long as practical. The higher earner’s delay raises the survivor benefit, which protects whichever spouse lives longer.
Working while you collect
If you claim before full retirement age and keep working, the earnings test can temporarily hold back some of your benefit. For 2026, the SSA withholds $1 for every $2 you earn above $24,480 if you are under full retirement age all year. In the year you reach full retirement age, the limit is $65,160 and the withholding is $1 for every $3 above it, counting only earnings before the month you reach that age.
The withheld money isn’t gone. Once you reach full retirement age, the SSA recalculates your benefit to account for the months it held back. Still, if you plan to keep working a full-time job at 62, claiming then often doesn’t make much sense, because a large part of the check may be withheld.
Other things worth knowing
Medicare eligibility starts at 65 no matter when you claim Social Security. You don’t have to start benefits to sign up for Medicare, and you should look at Medicare enrollment around your 65th birthday even if you plan to delay Social Security.
If you claim and then regret it, you can withdraw your application within 12 months of first becoming entitled. You have to pay back what you received, and you can only do this once.
Before you decide, create a my Social Security account at ssa.gov. It shows your earnings record and estimated benefits at different claiming ages, based on your actual history. Check the earnings record for missing years too. A year of work that was never recorded can lower your benefit, and it’s easier to fix while you still have the W-2s.
