The most common age Americans file for Social Security is 62, the earliest possible.
It's also, for many households, the most expensive decision they'll ever make.
Claiming that early permanently reduces your monthly benefit — often by hundreds of dollars that follow you for life.
Your "full retirement age" depends on your birth year: 66 and 10 months for those born in 1959, then 67 for anyone born in 1960 or later.
Claim at 62, and your check drops by up to 30% compared with waiting until your full retirement age.
Delayed retirement credits add roughly 8% per year until age 70, so a benefit claimed at 70 can run about 24% higher than at 67 and far more than at 62.
Say your full retirement benefit at 67 is $2,000 a month.
Claim at 62 and you're looking at roughly $1,400.
That's more than $1,000 a month in difference — about $13,000 a year — for as long as you live.
There's a catch that trips people up: Medicare.
If you sign up for Social Security before 65, you're not automatically enrolled in Medicare, and you'll need to handle that separately when you turn 65.
Miss the enrollment window and Part B premiums can cost you more later.
If you're laid off at 60, dealing with health problems, or supporting family, an early check beats an empty account.
That's a real trade-off, not a dumb mistake.
Claiming at 62 usually pays off only if you live into your late 70s or beyond.
Wait until 70 and break-even lands in your early 80s.
One more thing people miss: if you're married, the higher earner's decision affects both of you.
Survivor benefits are based on what the deceased spouse was receiving or entitled to.
When the higher earner delays, the surviving spouse typically gets a bigger check for decades.
If you're still working and claiming before full retirement age, the earnings test can temporarily withhold part of your benefit.
In 2025, the limit is $23,400; above that, $1 is withheld for every $2 earned.
It's not gone forever — it's recalculated later — but the check gets smaller now.
Log into your my Social Security account and pull your actual benefit estimates at 62, 67, and 70.
Then run your own break-even numbers with your real health, job, and spouse situation.
A free session with a Social Security advisor or a quick calculator can be eye-opening.
It's knowing the cost of claiming early before you click the button.
Millions of Americans file at 62 without ever seeing the three numbers side by side — and that's the part that quietly costs them. **Our take:** Social Security timing is one of the few retirement levers you fully control, and most people pull it without reading the fine print.
Final Thoughts
Spend 20 minutes with your real numbers before you file, because you can't undo this decision later.
