Average 401(k) Balance by Age

According to Vanguard's 2024 report, the average 401(k) balance increased by 19% compared to the previous year, showing that Americans are setting aside more for retirement. The 2025 report, which looks back at average and median 401(k) balances in 2024, has not yet been published.

While averages can be helpful, consider that the number tends to be skewed by outliers (either very high or very low numbers). The median is often a better metric for getting an accurate view of a data set. You'll notice that Vanguard's median balances are quite a bit lower than the averages.

The below numbers show how 401(k) balances increase with age, at least until participants start drawing on their money in retirement.

Under 25

Average 401(k) balance: $7,351

Median 401(k) balance: $2,816

Many of the participants in this age group are new to working and new to saving for retirement. Yet even at this age, it’s a good rule of thumb to prioritize contributing to your workplace retirement plan, especially if your employer matches a portion of your contributions.

These numbers don’t reflect what younger investors may have saved elsewhere, in taxable brokerage accounts or individual retirement accounts, such as Roth or traditional IRAs.

Age 25-34

Average 401(k) balance: $37,557

Median 401(k) balance: $14,933

At this point, whether measured by the average or the median, participants have increased their balances quite a bit. As people age and spend more time in the workforce, they’re more likely to hold more than one 401(k), especially if they’ve changed jobs without rolling over or combining accounts.

Age 35-44

Average 401(k) balance: $91,281

Median 401(k) balance: $35,537

Another solid jump by this age range, with both figures more than doubling — the last time we’ll see a percentage jump that large between age ranges. That’s likely at least partially a product of peak earning years. According to compensation research company Payscale, women hit their peak earnings on average at age 44. For men, that age is 55^[0]

Age 45-54

Average 401(k) balance: $168,646

Median 401(k) balance: $60,763

This group has hit the age at which catch-up contributions begin to be allowed by the IRS. In 2025, participants age 50 and older can contribute an additional $7,500, and those age 60 to 63 can contribute an extra $11,250^[0]

Age 55-64

Average 401(k) balance: $244,750

Median 401(k) balance: $87,571

Growth has slowed here, which makes sense, as people may start to withdraw the money they've been saving for retirement.

After this age group, 401(k) balances can begin to fall, or at least grow at a slower pace, as even more people start tapping their accounts. The average balance for those 65 and older is $272,588, and the median falls to $88,488.

Average 401(k) contribution rates

According to Vanguard's 2024 report, the average contribution rate among Vanguard plan participants was 11.7% in 2023, including matching employer contributions. The median contribution rate was not far behind, at 11%^[0]

If you want to beef up your account balance, one way to do it is to contribute at least enough to get the employer match if there's one offered. Another is to evaluate your 401(k) plan regularly and increase your contributions over time.

Average 401(k) match

The average employer match was 4.6% of pay, and the median was 4%, according to Vanguard. Most plans, 69%, followed a single-tier match formula. This is when an employer matches a specific amount on a set percentage of pay. For example, the match could be 50 cents per dollar on the first 6% of pay.

What you can learn from the average 401(k) balance

Not much. This is a fairly arbitrary benchmark. In the aggregate, it can generally speak to how workers are doing when it comes to saving for retirement, but it does little to help you analyze your own situation. It’s also limited to people who have a defined contribution plan at work, and not everyone does.

A better approach to benchmarking your efforts: A retirement calculator, which will give you a more personalized recommendation for how much you’ll need at the end of the line. (If you don't think you're saving enough, you might find our guide to retirement planning helpful.)

Finally, it’s worth noting that you may or may not want to put all your retirement eggs into a 401(k) basket. Should you max out your 401(k)? Maybe. But it isn't the best choice for everyone.
