The single date that most shapes how much your Social Security check is worth is your full retirement age, and for a large group of Americans that age has finished its long climb to 67. If you were born in 1960 or later, 67 is now the age at which you can collect your full benefit. Knowing that number, and what happens on either side of it, is the difference between a well-timed claim and one that quietly costs you money for life.
What “full retirement age” actually means
Full retirement age is the point at which you are entitled to 100% of the benefit your earnings record has built. According to the Social Security Administration, that age is 67 for people born in 1960 or later, the end of a gradual increase from the old age of 65 for earlier generations. It is not the same as the earliest age you can claim, which is 62, and it is not the latest, which is 70. Think of full retirement age as the anchor: claim before it and your monthly amount is reduced, claim after it and your amount grows.

The permanent cost of claiming early
The most important thing to understand about claiming before 67 is that the reduction is permanent, not temporary. If you start benefits at 62, your monthly check can be cut by roughly 30% compared with what you would receive at full retirement age, and that lower amount generally stays with you for the rest of your life, adjusted only for cost-of-living increases. People often assume the reduction disappears once they reach 67, but it does not. That does not make claiming early wrong, since health, job loss, or an immediate need for income can all justify it, but the decision should be made with clear eyes about the lifelong tradeoff.
The bonus for waiting past 67
Going the other direction, delaying past full retirement age earns you extra. For each year you wait beyond 67, up to age 70, Social Security adds delayed retirement credits that increase your benefit by about 8% a year. Wait all the way to 70 and your monthly check can be substantially larger than it would have been at 67. There is no benefit to waiting past 70, so 70 is the ceiling. For someone in good health with other income to live on in the meantime, delaying can function like a guaranteed, inflation-adjusted raise that lasts for life, which is hard to match anywhere else.
How to think through your own timing
The right claiming age is personal, and a few factors tend to drive it. Your health and family longevity matter, because delaying pays off most for those who live longer. Whether you are still working matters, since earnings before full retirement age can temporarily reduce benefits under the earnings test. And marital status matters, because a higher earner’s decision to delay can also raise the survivor benefit a spouse may one day receive. There is no universal right answer, only the one that fits your health, your savings, and your household. Running your own numbers on the Social Security Administration’s site, using your actual earnings record, beats relying on a rule of thumb.
Check your number before you decide anything
Before making any claiming decision, confirm your own full retirement age and see your estimated benefits at 62, at 67, and at 70 by opening a free my Social Security account on the agency’s website. Those personalized estimates turn an abstract rule into concrete dollar amounts you can weigh against your situation. The agency’s benefit-reduction guidance is the authoritative source for exactly how much an early claim cuts your check and how much delaying adds, and reviewing it with your real figures is the surest way to avoid an irreversible mistake. For most people, the biggest Social Security decision they will ever make comes down to understanding this one age and what sits on either side of it.
The earnings test that can surprise early claimers
One rule catches people who claim early while still working, and it is worth understanding before you file. If you take benefits before your full retirement age and keep earning above an annual limit, Social Security temporarily withholds part of your benefit under what is called the earnings test. That money is not lost forever; the agency recalculates and effectively credits it back once you reach full retirement age, so your benefit is adjusted upward later. But in the short term, a paycheck plus an early benefit can mean smaller checks than you expected, which is a common and unwelcome surprise for someone who claimed at 62 and kept a job.
Once you reach full retirement age, the earnings test disappears entirely, and you can earn any amount without a reduction to your benefit. That interaction between working and claiming is one more reason the full-retirement-age number sits at the center of the decision. The Social Security Administration’s guidance on the earnings test and on benefit reductions is the authoritative source for the current limits and how the withholding is later restored, and checking it with your own earnings in mind is the way to avoid a shortfall you did not plan for.
