The number that decides when millions of Americans can retire with full benefits has been quietly climbing for decades, and it isn't finished yet.
For anyone born in 1960 or later, the full retirement age sits at 67.
That's two years later than the 65 that workers born in 1937 or earlier received.
Claim at 62 and your monthly check is permanently reduced by 30% compared with waiting until 67.
Wait until 70, and you collect roughly 24% more than the full amount.
On a $2,000 full benefit, that's the difference between $1,400 and about $2,480 a month — for life.
The math gets harsher when you factor in health care.
Fidelity's latest estimate puts the average retired couple's health care costs around $315,000, and Medicare premiums often rise faster than the annual cost-of-living adjustment.
Every year you delay claiming is a year you need to cover premiums without a benefit check.
So why does 70 keep coming up in policy circles?
Because the trust funds are projected to run dry in the mid-2030s, and one commonly floated fix is raising the full retirement age again.
A jump to 68 or 69 would shave billions off the program's shortfall.
It would also mean today's 50-somethings work longer than they planned.
Physically demanding jobs, layoffs after 55, and caregiving duties push many workers to claim early whether they want to or not.
Roughly a quarter of new retirees start benefits at 62, the earliest possible age, often because they need the cash flow.
If you're married, the lower earner usually benefits from claiming based on the higher earner's record — but only once the higher earner files.
Coordinating two claiming dates can add tens of thousands of dollars over a retirement, and it's one of the few levers still fully in your control.
Pull your earnings record at ssa.gov and check for errors, since missing years drag your average down.
Run the numbers on claiming at 62, 67, and 70 for your specific situation.
And if you're behind on savings, treat catch-up contributions in a 401(k) or IRA as the priority, not the claiming date.
One more thing worth knowing: the Social Security Administration no longer mails paper statements to most workers, so if you haven't logged in recently, you may be flying blind on the single largest income source of your retirement.
Washington will eventually do something about the shortfall, but nobody knows what or when.
What's certain is that the full retirement age has already moved twice, and the trend line points one direction.
Planning for 70 — and being pleasantly surprised if you can retire sooner — beats assuming 65 will still work. **The takeaway:** The retirement age isn't a fixed target, it's a moving one, and the workers most hurt by further increases are the ones with the least flexibility to wait.
