If you were born in 1960 or later, your full retirement age is 67.
That single number decides whether your monthly check arrives whole or gets trimmed for life, and most Americans still guess it wrong.
It also lands in the middle of the worst stretch of grocery and rent inflation in decades, which makes the timing matter more than the rulebook suggests.
Full retirement age, or FRA, is when you qualify for 100% of your calculated benefit.
Claim at 62 and the reduction is steep: roughly 30% if your FRA is 67.
Wait until 70 and you earn delayed retirement credits of about 8% per year, which can push your check well above the base amount.
A $2,000 monthly benefit at 67 becomes about $1,400 at 62 and roughly $2,480 at 70, before annual cost-of-living adjustments.
Over a 20-year retirement, that gap can exceed six figures — real money when a cart of groceries runs $130 and rent keeps climbing.
Claiming early usually pays off only if you live into your late 70s or beyond; waiting tends to win past that.
Since none of us know our own timeline, many planners suggest treating longevity, health, and family history as the deciding factors rather than a single calculator.
If you claim before FRA and keep working, the earnings test can temporarily withhold part of your benefit once you pass the annual limit.
That withheld money isn't gone forever — it's added back once you reach FRA — but it can surprise people who are still covering rising rent and card balances.
Higher earners should also check the tax side.
Up to 85% of Social Security benefits can be taxable depending on your combined income, and those thresholds haven't moved in decades.
A raise at work or a bigger 401(k) withdrawal can quietly push more of your check into the taxable column.
For married couples, the decision is a team sport.
The lower earner often claims early to keep cash flowing, while the higher earner delays to lock in the larger survivor benefit.
That strategy can protect the surviving spouse for decades after the first death.
Whatever you choose, pull your official statement at ssa.gov and check your earnings record for errors now, not at 66.
Fixing a missing year of income is far easier while the paperwork still exists.
And if a caller claims they can boost your benefit for a fee, hang up — that's a scam, not a strategy.
The bottom line: 67 is a default, not a deadline.
Treat your claiming age like the biggest financial decision of your retirement, because for most households it is — worth more than a year of careful coupon-clipping.
Final Thoughts
Run your own numbers, factor in rent and groceries, and don't let a stranger on the phone decide it for you.
