The headline question has a short answer and a longer one. The short answer is that the average American nearing retirement has enough in a 401(k) to cover roughly 3 years of typical household spending. The longer answer involves Social Security, inflation, and a median balance that tells a very different story than the average.
Fidelity’s most recent participant data puts the average 401(k) balance at $246,500 for savers aged 60 to 64 and $251,400 for those aged 65 to 69. Vanguard’s How America Saves shows an average of $148,153, compared with a median of just $38,176. The gap between those two numbers carries most of the weight, and the typical household holds far less than the headline average suggests.
The Math on 10 Years of Spending
The Bureau of Labor Statistics reports average annual household expenditures of $78,535 in 2024. Ten years of that spending, assuming zero inflation, comes to $785,350. A retiree with the average balance covers 3.2 years of typical expenses before the account empties, while a retiree with the median balance covers less than six months. Social Security closes part of the gap.
The 2026 cost-of-living adjustment puts the average retired worker’s benefit at approximately $24,972 per year. Subtract that from the expenditure baseline, and a household still needs roughly $53,563 from savings or other income each year. At that pace, the average 401(k) balance lasts about 4.7 years, still well short of a decade. Apply the standard 4% withdrawal rule, and the same balance generates only $10,056 in sustainable annual income.
Inflation Makes 10 Years Look Worse
The CPI assumption of stable prices does not hold. The Consumer Price Index rose from 321.435 in June 2025 to 333.979 in May 2026, a 12-month increase of 4.2%. Core PCE, the Fed’s preferred gauge, climbed 2.7% over the same window. Even at the lower core reading, a year-one cost of living becomes roughly $100,000 by year 10. Healthcare drives much of that pressure.
The standard Medicare Part B premium rose to $202.90 per month in 2026, up from $185 in 2025, and the Part A hospital deductible jumped to $1,736. Out-of-pocket costs in retirement rise faster than headline inflation, which is why projecting a flat baseline understates the real bill.
Why Households Are Not Catching Up
Two trends explain the shortfall. The personal savings rate fell from 6.2% in early 2024 to 3.7% in the first quarter of 2026, a period marked by high volatility. Per capita disposable income has remained constrained, leaving little headroom after the average expenditure load. Median full-time weekly earnings of $1,235 in the first quarter of 2026 translate to about $64,220 a year before tax.
Real average hourly earnings were $11.24 in May 2026, essentially flat with $11.32 a year earlier. Fidelity’s guideline calls for 10 times salary saved by age 67, and Schwab’s 2025 participant survey pegged the “magic number” at $1.6 million. The average balance for retirement-age savers comes in under $252,000, roughly one-sixth of that target.
The Bottom Line
For the average American 401(k) saver, current balances do not cover 10 years of typical household spending on their own. Social Security stretches the runway, but a meaningful gap remains for anyone aiming to maintain pre-retirement living standards. For the median household, savings cover only a fraction of a year, which means Social Security functions less as a supplement and more as the primary source of income. The gap between the average and the median is the figure worth watching.
