Reaching your 60s with more than a quarter-million dollars in a 401(k) may sound reassuring. But measured against what American households actually spend, that balance is not nearly as large as it first appears.
The comparison is deliberately blunt. It does not account for Social Security, investment returns, pensions, taxes, or lower spending after retirement. Still, it shows why households nearing retirement cannot afford to avoid money mistakes or assume that a six-figure balance automatically means they are prepared.
Here is what the numbers reveal.
The average balance covers about 3.3 years
Fidelity reports that participants ages 60 to 64 have an average workplace 401(k) balance of $257,400. Meanwhile, the Bureau of Labor Statistics says the average consumer unit spent $78,535 in 2024.
Divide $257,535 by $78,535, and the result is around 3.28 years. That is about three years and three months of average spending, assuming no other income and no investment growth.
The calculation is simple, but intentionally harsh
Nobody retires by withdrawing an entire year's expenses from a motionless account each January. Investments may keep earning money, and most retirees receive Social Security. Some also have pensions, part-time income, or home equity.
However, market losses, taxes, inflation, and unexpected bills can work in the other direction. The calculation is not a retirement plan. It is a way to show how quickly an apparently substantial balance could be consumed.
The median tells a more troubling story
Averages can be pulled upwards by participants with very large accounts. The median shows the balance held by the person in the middle and may offer a better picture of a typical saver.
Vanguard reports a median balance of $95,642 among participants ages 55 to 64. At $78,535 in annual spending, that amount would cover just over a year of spending.

This does not describe every American household
The Fidelity and Vanguard numbers cover participants in retirement plans administered by those companies. They do not include every American, and they don't capture money held in a spouse's account, an IRA, a pension, or another former employer's plan.
The BLS figure also represents average spending across consumer units of different ages. An individual retiree's actual budget could be considerably lower (or higher).
The benchmark gap is still substantial
Fidelity's retirement guideline suggests having eight times your annual income saved by age 60. The latest Census Bureau figure puts the median U.S. household income at $83,730.
Under the Fidelity guideline, that household would aim for approximately $669,840 by age 60. That is about 2.6 times Fidelity's reported average balance of $257,400 for participants ages 60 to 64.
Social Security stretches the money further
The Social Security Administration estimated that the average retired worker would receive $2,071 per month in January 2026, or $24,852 annually. Subtracting that from $78,535 leaves an annual gap of $53,683.
At that withdrawal rate, $257,400 could cover approximately 4.8 years rather than 3.3 years. The $87,571 median could cover about 20 months.
Social Security may become the primary income source
Those examples combine an individual Social Security benefit with household-level spending, so they should not be treated as personalized projections. A married household often collects two benefits, while a single retiree could spend much less than the national average.
Even with that said, the median balance suggests that Social Security often provides the foundation of retirement income for many households rather than just supplementing their savings.
Workers in their early 60s have a larger catch-up limit
People approaching retirement still have time to improve their numbers. In 2026, workers aged 50 or older can contribute as much as $32,500 to a 401(k), including the standard catch-up contribution.
Workers ages 60 through 63 may contribute up to $35,750 if their employer's plan permits the higher SECURE 2.0 catch-up. That additional room could make the final working years unusually valuable.
Delaying Social Security can increase monthly income
Waiting beyond full retirement age to claim Social Security can earn delayed retirement credits until age 70. For people born in 1943 or later, those credits generally equal 8% for each full year of delay, although they are calculated monthly.
Delaying is not right for everyone, though. Health, life expectancy, marital benefits, employment, and available savings should all factor into the decision.
Roth conversions require careful timing
The years after leaving work but before required minimum distributions begin may provide an opportunity to convert some traditional retirement money to a Roth IRA at a relatively low tax rate.
Conversions create taxable income, though. Large conversions may also raise Medicare premiums, impact the taxation of Social Security benefits, or push income into a higher bracket. This strategy is typically more useful when planned over several years than when completed all at once.
Bottom line
A retirement account worth hundreds of thousands of dollars can still disappear faster than expected once retirement begins. Social Security can extend the runway, but many retirees still need to plan withdrawals carefully, especially when retirement savings are stretched thin.
One practical step is to separate essential expenses from flexible ones before leaving work. Cutting even $500 a month in discretionary spending could reduce annual withdrawals by $6,000, giving savings more time to recover from market downturns and potentially lowering the risk of running short later.
