The conventional retirement story in the United States focuses on when people do retire. Far less attention goes to when they do not — and why. Federal benefit data and decades of longitudinal surveys now make it possible to identify the ages Americans most consistently avoid.
The pattern is not random because, as we’ve found out, it follows the architecture of a system that rewards specific choices and quietly penalizes others.
Why Most Americans Never Retire at 63 or 64
Ages 63 and 64 rank among the least common retirement ages in the country. According to benefit uptake data compiled from Social Security Administration records and analyzed by Boldin Financial, these two ages each account for between 6% and 9% of all retirement benefit claims — the lowest figures across the entire eligible spectrum. To understand why, it helps to understand what makes 62 and 65 so dominant by comparison.
At age 62, workers gain access to Social Security for the first time. At age 65, Medicare coverage begins. These two dates act as gravitational anchors in retirement planning. Workers who leave the workforce at 63 or 64 have already passed the first threshold without maximizing it, and have not yet reached the second. The result is a gap that carries real financial cost.
Social Security Penalty, Lost Wages, Costly Insurance
Retiring at 63 or 64 means claiming Social Security at a reduced rate — the same permanent reduction that applies at 62 — while also forfeiting one or two additional years of earnings and contributions. It also means paying for private health insurance during the Medicare waiting period, a cost that the Kaiser Family Foundation estimates can run between $700 and $1,200 per month for an individual in their early 60s without employer coverage.
There is no structural benefit that activates at 63 or 64. No bonus, no threshold, no federal milestone. For workers who have already decided to leave early, 62 is simply more rational. For those who can stay longer, the calculus points toward 65, 66, or 67.
Retiring at 70 or Later: 80% Higher Benefit, But Few Do It
On the opposite end of the spectrum, retiring at 70 or later is theoretically the most financially rewarding option. Delaying Social Security to 70 yields a monthly benefit of approximately $5,181 for average earners, compared to roughly $2,831 at 62, according to SSA benefit calculators. That is an 80% difference in monthly income.
Yet the 2025 Employee Benefit Research Institute Retirement Confidence Survey found that 30% of workers plan to retire at 70 or later — while only 9% of actual retirees report having done so. The gap between intention and outcome is wider here than at any other age in the survey.
The reasons are largely involuntary. The same EBRI study found that 38% of workers who retired earlier than planned cited health problems or disability as the primary factor, while 23% pointed to employment disruptions including layoffs and business closures. Decades of data from Gallup support the same conclusion: workers consistently overestimate how long they will be able to stay in the labor force.
Retiring Too Early Is Rare As Well
Retirement before 55 is even rarer, and for structural reasons that go beyond personal choice. No Social Security access exists below 62. Withdrawals from 401(k) accounts before age 59½ are subject to a 10% federal penalty under IRS rules. Medicare remains a decade away for someone stepping out at 50. The financial infrastructure that makes retirement viable simply does not exist at those ages for most workers.
Between 2016 and 2022, just 6% of Americans retired between ages 50 and 54, down from 9% in the decade prior, according to data from the Guardian Life longitudinal retirement study. That decline tracks directly with rising healthcare costs and the effective disappearance of defined-benefit pension plans, which previously allowed earlier exits.
