If you were born in 1960 or later, your full retirement age is 67.
That single number trips up more Americans than almost any other retirement rule, and the confusion gets expensive fast.
Here's the part that catches people off guard.
You can still claim Social Security at 62, but doing so permanently shrinks your monthly check.
Claim at 62 with a full retirement age of 67, and you're looking at roughly a 30% reduction for life.
Wait until 70 instead, and you could see a sizable bump above your full benefit.
The math is unforgiving because it never resets.
A smaller check at 62 follows you through every cost-of-living adjustment, so the gap widens over decades of retirement.
For someone expecting $1,800 a month at 67, claiming at 62 could mean closer to $1,260, and that difference compounds for 20-plus years.
The 1983 amendments set this slow climb in motion, phasing the full retirement age from 65 to 67 in two-month increments depending on your birth year.
Anyone born in 1959 hits 66 and 10 months.
There's no further increase on the books right now, despite recurring Washington chatter about pushing it higher.
What most people miss is that 62 isn't the only early option.
Benefits are calculated monthly, so waiting even a few months past your birthday adds a little each time.
The penalty shrinks gradually until you reach full retirement age, then the bonus for waiting starts stacking up at about 8% per year until 70.
Health and work history matter here more than spreadsheets suggest.
If you're still earning a paycheck before full retirement age, the earnings test can temporarily withhold part of your benefit.
In 2025, that threshold sits around $23,400, with $1 withheld for every $2 above it.
The money isn't gone forever, but it's a nasty surprise for people who claim early while still working.
Spousal and survivor benefits add another layer.
A lower-earning spouse often does better waiting, because survivor benefits are based on the higher earner's record.
If the higher earner claims early, the surviving spouse inherits that reduced amount for the rest of their life.
That's a decision worth slowing down for.
Pull your statement at ssa.gov and look at the three numbers: age 62, full retirement age, and 70.
Then check whether you have other income to bridge the gap.
Even a part-time job or a small pension can make waiting pay off.
If you're married, run the survivor scenario before filing.
One more thing worth knowing: Medicare starts at 65 regardless of when you claim Social Security.
Don't let health coverage pressure you into filing early.
You can sign up for Medicare without touching your retirement benefit.
The system rewards patience, but patience requires cash flow.
That's the real tension most retirees face.
Our take: the retirement age debate gets framed as a policy fight, but for most households it's a personal deadline hiding in plain sight.
Final Thoughts
Knowing your exact full retirement age, and what early claiming truly costs, is one of the few retirement moves you can make for free.
