Retiring at 62 costs the average American $250,000. Here’s the math (and the neuroscience) that explain why

The biggest financial risk most American retirees still underestimate is not the market. It is longevity. The risk of outliving the plan.
Fortune‘s Sasha Rogelberg reported in May on new research from the National Bureau of Economic Research showing that Gen X workers who retire early pay a steep cognitive price for it. That is the health story, and it is real. The financial story underneath it is bigger, and it is the one most still do not understand.
Retiring at 62 instead of 67 amplifies longevity risk in three directions at once. It locks in a permanently lower Social Security benefit. It stretches the most fragile decumulation window by five years, exactly the years when sequence-of-returns risk does the most damage. And it accelerates cognitive decline in the very period when retirement decisions get more complex, not less. For an average earner, that single set of choices is roughly a quarter-million dollars in lifetime income left on the table.
The conventional wisdom told a generation that early retirement was the reward. The math, the data, and now the neuroscience tell a different story.
The 65 myth
Start with the number itself. Sixty-five was never a biological milestone. It can be directly traced to 1889, when German Chancellor Otto von Bismarck established it as the basis for Germany’s national pension system. The retirement age was first set at 70, then lowered to 65, chosen so that the first national pension system could offer generous benefits and cost the state virtually nothing. The reason was simple: hardly anyone lived much longer than 65 at that time. That number was imported by Franklin Roosevelt into Social Security in 1935. The math worked then because most Americans were not expected to collect a benefit.
No longer. A 65-year-old American man can now expect another 18 years. A woman, another 21. That is the average. Half of Americans will live a decade more. Roughly one in four 65-year-olds today will live past 90. Centenarians are the fastest-growing demographic segment in America. We are still running a retirement framework designed for lives that no longer exist. That makes the conventional idea of retiring at 65 the single most dangerous piece of retirement advice in circulation.
It is time to rethink what retirement is and what it should look like, both for our health and for our finances.
The first multiplier
Claiming Social Security at 62 locks in a permanently lower benefit. The reduction relative to full retirement age is roughly 30%. Waiting until 70 increases the benefit by about 77% versus claiming at 62.
For most Americans, delaying Social Security is the single highest-return financial decision available to them.
Leaving the workforce to claim benefits early may feel like a good decision. In 1935, it would have been. Today it is not. For an average worker who would have received a monthly benefit of $2,500 at full retirement age, claiming at 62 cuts that to roughly $1,750 a month for life. Waiting until 70 raises it to roughly $3,100. Multiply the gap across a 30-year retirement and you are looking at well over a quarter of a million dollars in foregone lifetime income from a single click on a government website.
Most retirees do not get to make that decision twice.
The second multiplier
Retire at 62 instead of 67 and you do not just get a reduced lifetime income stream from Social Security. You also add years to the most fragile financial phase of retirement. Early retirement means you begin withdrawing from savings to live. Withdrawing during a market downturn locks in losses that permanently damage retirement security.
This is sequence-of-returns risk. You end up with less in savings to recover with when the markets rebound, because the bad years took the money before the good years could compound it. The early retirement years are when a portfolio is most vulnerable to bad market sequences, and starting five years earlier means five more years exposed to that vulnerability.
A 15-year retirement is one mathematical exercise. A 35-year retirement is another entirely. The portfolio that looked durable at 65 looks fragile at eighty when markets sell off, inflation rises, and there is still a decade or more of life ahead. The retiree at 62 will not see it until it is too late to recover.
The third multiplier
This is where Rogelberg’s reporting becomes critical for retirement planning. A working paper from the National Bureau of Economic Research, by economists at UC Irvine, found something more pointed than correlation. They found causation. Among American men aged 51 to 64, leaving the workforce led to measurable cognitive decline. Staying in led to greater sustained cognition. That is the Gen X window. That is my generation.
Late-life financial decisions are not simple. Tax-efficient withdrawals. Medicare premium brackets. Long-term care timing. Roth conversion windows. Estate decisions. The years when these decisions matter most are the years when, on average, our mental capacity to make them is shrinking. Retiring early does not just stretch the finances. It degrades the very instrument needed to manage them.
Cognitive decline during aging does not announce itself. It shows up in mistakes. Forgetfulness. Errors in judgment. It shows up as a portfolio that has not been rebalanced in four years. It shows up as a required minimum distribution that nobody caught in time. The science of healthy aging is one more reason the old framework breaks. The financial implications are barely understood.
A different architecture
The answer is not that everyone must work until 80. People burn out. Bodies wear out. Ageism pushes capable workers out before they are ready. “Just work longer” is a slogan, not a plan.
The answer is to re-architect retirement for a 30-year second act instead of a five-year one. That means two things, and the rest follows from them.
First, stay engaged in work that gives the brain a reason to show up. Paid or unpaid. The Okinawans call it ikigai, a reason to get up in the morning. The American version is simpler: stop treating 65 as the finish line.
Second, build a guaranteed income floor that can last into the eighties and nineties. You cannot afford to panic-sell in your 70s. Plan to 95. Stress-test to 100. Treat the decision of when to claim Social Security for what it really is: a longevity bet, made once, with no second click.
The retirement most Americans understand is built for shorter lives. The one they will live must be built for longer ones.

Four leading AI models discuss this article
"The 'work longer' strategy is a dangerous assumption that ignores the systemic reality of involuntary early retirement and the subsequent depletion of retirement accounts."
The article correctly highlights the 'longevity risk' math, but it ignores the reality of the labor market. While delaying Social Security to 70 is mathematically optimal, it assumes the worker remains employable and healthy enough to earn a high income during those extra years. For the average American, the biggest risk isn't just the 'decumulation window'—it's the 'involuntary retirement' forced by ageism, automation, or health shocks. If you plan to work until 70 to maximize your benefit but are pushed out at 62, your sequence-of-returns risk is actually magnified because you are forced to draw down your 401(k) while your Social Security is still suppressed.
The author assumes work is the primary driver of cognitive health, but fails to account for the high stress and physiological toll of modern corporate environments which may accelerate decline faster than retirement.
"The $250k math is real for average earners, but the article mistakes a problem of *optimization* for a problem of *necessity*, ignoring that millions lack the choice to work until 70."
The article makes a mathematically sound case about Social Security optimization and sequence-of-returns risk, but conflates three separate problems into one. Yes, claiming at 62 vs. 70 costs ~$250k for average earners—that's actuarially defensible. Yes, early withdrawal during downturns damages portfolios. But the neuroscience claim is oversold: the NBER study shows correlation in *leaving the workforce*, not necessarily in retiring with sufficient income. A 62-year-old with $2M in assets and $50k annual spending faces different cognitive and financial pressures than one with $400k and $40k needs. The article also ignores that many Americans *cannot* work until 70 due to health, caregiving, or job loss—making 'just work longer' tone-deaf to structural inequality.
If cognitive decline is real and accelerating, early retirees might make *worse* financial decisions precisely because they have more years to compound errors—but the article provides no evidence that staying employed prevents this, only that it correlates with better cognition during employment.
"The $250k cost of claiming at 62 is actuarially accurate for those who can wait, but health-driven forced retirements render the strategy inaccessible for a material share of workers."
The article correctly quantifies the SS claiming penalty—30% cut at 62 versus 77% uplift at 70, equating to roughly $250k lifetime for an average $2,500 monthly benefit—but understates selection bias in the NBER cognitive findings and the prevalence of involuntary early exits. Sequence-of-returns exposure over five extra years is real, yet rising age discrimination and physically demanding occupations make blanket delay advice fragile. Missing are hybrid options like part-time consulting that preserve both income and cognition without full-time work until 67-70.
Even after health adjustments, actuarial tables show delaying SS still delivers the highest risk-free return available to most households able to bridge the gap, and longitudinal data consistently link workforce engagement to slower cognitive decline.
"The article overstates the universal financial impact of retiring at 62 by using a single, fragile benchmark; the optimal path depends on individual life expectancy, healthcare costs, investment strategy, and the availability of phased retirement options."
Solid framing on longevity risk and the finance-psychology link, but the math is fragile. The $250k figure hinges on life expectancy, market returns, and Social Security indexing that vary by person, and the claimed causal link between early retirement and cognitive decline is not established in a robust way here (risk may reflect health-driven retirement). The piece glosses policy risk (trust fund timing), healthcare costs, and the viability of phased or partial retirement. A more robust playbook is a personalized glide path: phased work, diversified withdrawal strategies, and a guaranteed income floor—not a universal delay-to-70 mandate.
The strongest counter is that the cognitive-decline claim may be non-causal or confounded by health status; early retirement with flexible, phased work can mitigate risk and preserve wealth, so the $250k figure may overstate universal harm.
"The 'delay to 70' strategy often fails due to tax inefficiency during the bridge years, not just health or labor market risks."
Claude and Grok both miss the second-order impact of the 'bridge' period. If a 62-year-old pivots to part-time consulting to delay Social Security, they face a massive tax cliff. Drawing down 401(k) assets to replace income while still in a high tax bracket, before SS kicks in, often destroys the very 'mathematical optimization' they crave. We are ignoring the interaction between progressive tax brackets and the timing of taxable withdrawals. It is not just about health; it is about tax-efficient decumulation.
"Tax-efficient decumulation during the bridge is solvable via Roth conversion strategy, not an argument against delaying SS itself."
Gemini's tax-bracket point is sharp but incomplete. The 401(k) withdrawal cliff exists—but so does the Roth conversion ladder, which many advisors exploit precisely during the 62-70 bridge. Phased Roth conversions at lower brackets *before* SS kicks in can actually optimize lifetime taxes. The real trap is claiming SS early *and* drawing taxable accounts simultaneously. That's where the math breaks. Hybrid work alone doesn't solve it; tax sequencing does.
"Roth conversions carry overlooked IRMAA costs that undermine the tax optimization strategy."
Claude overlooks how Roth conversions trigger IRMAA surcharges on Medicare premiums, which can erase much of the tax benefit. Converting $40k annually from 62-70 pushes MAGI over $118k for couples, adding $2,400+ yearly costs from age 65. This interacts directly with Gemini's tax cliff, creating a hidden decumulation penalty that neither tax sequencing nor part-time work fully mitigates for middle-income households.
"Roth ladders alone don't solve the tax cliff; IRMAA and MAGI interactions demand a dynamic, income-smoothing glide path rather than a fixed 62–70 bridge."
You're right that Roth conversions can mitigate the tax cliff, but the IRMAA angle Grok highlights is a material, often overlooked constraint. Converting $40k annually to stay in a lower bracket can push MAGI into Medicare surcharges later years, eroding any tax delta. The lesson: tax sequencing must be dynamic—part-year conversions, bridging with qualified funds, and intentional SS timing—not a plug-and-play 62–70 ladder.
The panel agrees that delaying Social Security to 70 is mathematically optimal but ignores the reality of the labor market and health risks. The biggest risk is involuntary retirement due to ageism, automation, or health shocks, which can magnify sequence-of-returns risk. Hybrid options like part-time consulting and tax sequencing strategies are suggested to mitigate these risks.
