Millions of Americans have a number in their heads for when Social Security kicks in, and a big chunk of them are quietly wrong about it.
The full retirement age — the point at which you collect 100% of your benefit — is no longer 65 for anyone born in 1960 or later.
That shift happened gradually, and it finished phasing in back in 2022.
But surveys keep finding that a large share of workers still assume 65 is the magic date.
Getting this wrong by two years can shrink a monthly check by hundreds of dollars for the rest of your life.
Claim at 62, the earliest possible, and your benefit is cut by up to 30% compared with waiting until 67.
Wait past 67, and your check grows about 8% for every year you hold off, up to age 70.
That delayed retirement credit is one of the few guaranteed inflation-beating bumps available to ordinary savers.
Say your full benefit at 67 would be $2,000 a month.
Over a 20-year retirement, that spread can exceed $200,000 — real money for households already squeezed by grocery bills and rent.
The higher earner usually should delay, because survivor benefits are based on the larger check.
When one spouse dies, the smaller benefit stops and the larger one continues.
A bigger top benefit protects the surviving partner, who is statistically likely to be the wife.
Health problems, a layoff, or a need to stop physically demanding work can make waiting impossible.
The system was built with that flexibility on purpose.
But filing early purely out of impatience, or because a friend said 65, is an expensive mistake.
Check your actual numbers at ssa.gov before deciding anything.
The statement shows your estimated benefit at 62, at your full retirement age, and at 70.
It takes about 10 minutes and it is free.
First, if you claim before your full retirement age and keep working, part of your benefit can be temporarily withheld if you earn above an annual limit.
Second, Medicare starts at 65 regardless of your Social Security age, so you may need to sign up even if you are not collecting yet.
The bottom line: the retirement age did not stay at 65, and treating it that way can cost you a six-figure sum over a long retirement.
Final Thoughts
Know your date, run your numbers, and decide on purpose rather than by habit.
