Claiming Social Security at instead of your full retirement age permanently cuts your monthly check by up to 30 percent — forever. I didn’t fully grasp that number until I sat down with my own estimated benefit statement in . I was born in . My full retirement age is 67. If I claim at 62, I leave roughly $145,000 on the table over a 20-year retirement. That math changed how I think about everything.
If you were born in or later, your full retirement age (FRA) is 67. Every month you claim before FRA reduces your benefit permanently. Every month you delay past FRA — up to age 70 — earns an 8% annual bonus. Getting this date wrong costs real money.

I’m Sloane Avery Wren. I cover Social Security, Medicare, and the intersection where personal finance gets genuinely complicated. For years, I wrote about retirement age in the abstract. Then I turned 63 in , and the chart stopped being abstract.
My estimated benefit at 67 is $2,610 per month. At 62, it would have been $1,827 per month — about what a one-bedroom costs in Austin, Texas in . At 70, it climbs to $3,238 per month. Those three numbers represent three entirely different retirements. The retirement age chart is the key to unlocking which one you get.
I’ve talked to readers in their late 50s who assume their FRA is 65 — because that’s what their parents told them. It hasn’t been 65 for most workers since . The full retirement age has been rising gradually since 1938, when it first moved past 65 for workers born that year. If you’re using the wrong number, your entire retirement timeline is built on a mistake.

The table below reflects the official Social Security Administration schedule for full retirement age and the benefit reduction if you claim at 62. I’ve added the monthly dollar impact using the average retired-worker benefit of approximately $2,025/month as a baseline — roughly the cost of a one-bedroom apartment in Columbus, Ohio.
| Birth Year | Full Retirement Age | Months Before FRA at 62 | Reduction at 62 | Approx. Monthly Impact |
|---|---|---|---|---|
| 1943–1954 | 66 | 48 | 25.0% | −$506/mo |
| 1955 | 66 + 2 months | 50 | 25.83% | −$523/mo |
| 1956 | 66 + 4 months | 52 | 26.67% | −$540/mo |
| 1957 | 66 + 6 months | 54 | 27.50% | −$557/mo |
| 1958 | 66 + 8 months | 56 | 28.33% | −$574/mo |
| 1959 | 66 + 10 months | 58 | 29.17% | −$591/mo |
| 1960 or later | 67 | 60 | 30.00% | −$608/mo |
Dollar reductions based on an illustrative FRA benefit of $2,025/month. Your actual benefit will differ.

SSA uses a two-tier formula. The rate is steeper for the first 36 months and flatter beyond that.
I find it easiest to think of it in two separate buckets.
Bucket 1 — First 36 Months Early
SSA reduces your benefit by 5/9 of 1% per month.
That equals exactly 20% for a full 36 months.
Everyone who claims before FRA passes through this bucket first.
Bucket 2 — Months 37 Through 60 Early
Each additional month adds 5/12 of 1%.
Workers born in or later who claim at 62 have 60 months total —
24 extra months at the slower rate add another 10%.
Quick Example — Born , FRA = 67
- Claim at 62 → 60 months early
- First 36 months × (5/9)% = 20.00% reduction
- Next 24 months × (5/12)% = 10.00% reduction
- Total reduction: 30.00%
- On a $2,025 FRA benefit → you receive $1,418/month
