Ask ten people when they can collect full Social Security and you will likely get ten different answers.
The most common guess is 65, a number that has not been the full retirement age for anyone born after 1959.
For millions of workers nearing the end of their careers, that outdated figure could mean a permanent cut to their monthly check.
Full retirement age, the point at which you receive 100% of your earned benefit, is 67 for anyone born in 1960 or later.
Claim at 62, the earliest allowed, and your payment is reduced by about 30%.
Wait until 70, and you collect roughly 24% more than your full amount, plus any cost-of-living adjustments stacked on top.
Say your full benefit at 67 would be $1,900 a month.
Over a 20-year retirement, the gap between the earliest and latest claim can exceed $200,000.
It is a mortgage payment, or several years of groceries.
You need income to bridge the gap, and not everyone has a job that lets them keep working into their late 60s.
Health problems, layoffs, and caregiving duties derail plenty of plans.
Claiming early is sometimes the only realistic option, and there is no shame in that.
If you claim before full retirement age and keep working, the Social Security Administration withholds part of your benefit once your earnings pass a threshold, which sits around $23,400 this year.
It gets added back into your benefit once you reach full retirement age, but the temporary hit catches workers off guard every year.
For couples, the decision gets more complicated and more valuable.
The higher earner usually benefits most from waiting, because the survivor benefit is based on their record.
When one spouse passes, the other keeps the larger of the two checks, not both.
Delaying the bigger benefit can protect the surviving spouse for decades.
Start by creating a free account at ssa.gov and checking your actual estimated benefits at 62, 67, and 70.
Those personalized numbers beat any rule of thumb.
Then look at your savings, your health, and whether you can realistically work longer.
If you are married, run the survivor math too.
One practical move: if you are within a few years of claiming and still working, consider scheduling a free appointment with a Social Security representative or a fee-only financial planner who does not sell products.
A single hour of advice can be worth tens of thousands over a retirement.
The bottom line is that full retirement age is not a finish line, it is a dial.
Turning it changes your income for the rest of your life.

Most people spend more time researching a car purchase than they do this decision, and that is a costly habit.
