By 66, many Americans are either already retired, preparing to claim Social Security, or trying to figure out whether their savings will realistically support the next 20 to 30 years. That makes it an important time to check up on your retirement readiness, especially since inflation and rising health care costs continue to put pressure on retirement budgets.
The good news is that plenty of people still have time to improve their financial position at 66, even if their savings aren't perfect. But current 401(k) data also shows many Americans are entering retirement with less than they expected. Here's how the average balance compares.

The average 401(k) balance at 66
According to Fidelity, Americans aged 65 to 69 have an average 401(k) balance of $251,000. Empower puts that average much higher for those in their 60s, closer to $578,000. At first glance, that may seem like a lot of money.
However, averages can be misleading as they're heavily influenced by high earners with very large accounts. Many retirees have significantly less saved, especially those who spent time out of the workforce or struggled to consistently contribute during their working years.
The median balance paints a more realistic picture
The median 401(k) balance for Americans in their late 60s is much lower, closer to $187,249, according to recent data from Empower.
Median balances offer a clear picture of what the "typical" retiree actually has available. Because it's the middle number in the data set, it isn't as skewed by very low or very high balances. While $200,000 could still help supplement Social Security and other income, it may not generate enough to fully support retirement spending for decades without careful budgeting.
For many households, retirement income ends up coming from several sources working together rather than one large account balance alone.
Many 66-year-olds are still carrying debt
One reason retirement savings might not feel like they're enough is that many older Americans are also managing debt.
According to the Employee Benefit Research Institute, about 65% of households led by someone ages 65 to 74 still carry debt. This data includes mortgages, auto loans, credit card debt, and even student loans. A retiree with a paid-off home and modest expenses may feel comfortable with a smaller nest egg, while someone with monthly debt payments could feel financially stretched even with larger savings.
That's one reason experts often recommend looking at spending needs and not just account balances.
Health care costs are a big factor
At 66, many retirees are adjusting to Medicare, supplemental insurance costs, prescription expenses, and out-of-pocket health care spending. According to estimates from Fidelity, the average retired couple may need hundreds of thousands of dollars saved specifically for health care expenses in retirement.
That doesn't mean everyone will spend that much directly out of pocket. But health care inflation is one of the largest long-term pressures on retirement savings, especially later in life.
A higher balance doesn't always mean financial security
It's easy to assume someone with $700,000 or $1 million in a 401(k) is automatically comfortable. But retirement security depends heavily on lifestyle, location, taxes, and spending habits. Someone living a relatively modest lifestyle in a low-cost area with little debt may be financially comfortable, while a retiree with double the savings but very high expenses may struggle.
That's why financial planners often focus more on sustainable withdrawal rates and realistic spending projections rather than using one "magic number" retirement target for everyone.
Delaying Social Security can help stretch savings
For some Americans, waiting longer to claim Social Security may reduce pressure on retirement accounts. Monthly Social Security checks increase by 8% for each year benefits are delayed beyond full retirement age, up to age 70. That larger guaranteed income stream may help retirees rely less on early withdrawals from their 401(k)s.
Of course, delaying benefits isn't realistic for everyone. Health concerns and job loss can sometimes force early claims. But for retirees who can wait, the higher monthly benefit may provide more flexibility later.
Catch-up contributions may help late savers
Catch-up contributions allow workers to contribute additional money to workplace retirement plans at age 50 and beyond. Those who take advantage of these increased contributions during peak earning years can make up lost ground faster than expected, especially during strong market periods.
Similarly, workers who paused investing during downturns or withdrew funds early often enter retirement with significantly smaller balances despite similar incomes over their careers.
Bottom line
The average 401(k) balance at 66 may seem like a lot at first glance, but median balances reveal that retirees are working with far less than many expect. Rising health care costs, inflation, and longer retirement mean even six-figure savings accounts may need to stretch over time. Looking at your spending habits and monthly obligations often gives you a clearer picture of how well you're prepared for retirement than comparing yourself to national averages.
Don't forget about taxes, as well. Withdrawals from traditional 401(k)s are generally taxed as ordinary income, which can impact how far those savings actually go each year. That's why reviewing withdrawal strategies, required minimum distributions, and overall cash flow could be just as important as the balance itself.
