If you were born in 1960 or later, the age at which you can collect full Social Security benefits is not 65.
It hasn't been for years, and a surprising number of Americans are still planning their retirement around a number that no longer applies to them.
For anyone born in 1960 or later, full retirement age is 67.
That's up from 66 for people born between 1943 and 1954, and the increase is already fully phased in.
There is no more gradual climb ahead — 67 is the ceiling for now.
The confusion matters because claiming early carries a permanent cost.
You can start benefits at 62, but doing so reduces your monthly check by up to 30% compared with waiting until 67.
That reduction isn't a temporary haircut.
It follows you for life, with only modest annual cost-of-living adjustments applied to the smaller base.
Waiting past 67 increases your benefit by roughly 8% per year until age 70.
For a worker who would receive $2,000 a month at 67, holding out until 70 pushes that closer to $2,480 — and that higher figure becomes the foundation for every future COLA.
Over a 20-year retirement, the gap can easily run into six figures.
The break-even math is the starting point, not the answer.
Someone in average health who expects to live well into their 80s usually comes out ahead by waiting.
Someone with a shorter life expectancy, or a real need for cash now, may reasonably claim early.
Spousal and survivor benefits complicate things further, and for married couples, the higher earner often benefits most from delaying.
A few practical moves can help before you file.
Create a my Social Security account at ssa.gov to see your actual estimated benefit at each claiming age — not a guess, your real numbers.
Check your earnings record for errors, since missing years can quietly shrink your payment.
And if you're still working while claiming before full retirement age, understand the earnings test: in 2024, benefits are reduced by $1 for every $2 earned above $22,320.
There's also a planning trap worth naming.
Many people assume Medicare and Social Security start together at 65.
Medicare eligibility does begin at 65, but that has nothing to do with when you should claim retirement benefits.
Treating them as a package deal can cost you tens of thousands over a lifetime.
The best move is to run your own numbers rather than relying on the age a coworker retired or a number you heard years ago.
A few hours with the SSA's calculators, or a session with a fee-only planner, can change the single biggest financial decision most Americans ever make.
Final Thoughts
The program's long-term funding questions get plenty of headlines, but the rules that affect your monthly check are already written.
