- The average 401(k) balance sits at $148,153, but the median — the number right in the middle of all savers — is just $38,176, according to 24/7 Wall St.'s reporting via Google News.
- Vanguard's How America Saves 2024 report, based on 5 million participants, puts the median even lower at $35,286, with an average of $134,128 — a different snapshot than 24/7 Wall St.'s figures, but the same story.
- Fidelity's Q3 2024 data shows an average balance of $132,300, up 23% year-over-year, while workers 55-64 carry a median of roughly $61,530 — still short of what most benchmarks call adequate.
- Only about 14% of Vanguard's 401(k) participants have crossed $250,000, meaning the six-figure "average" is a story about a minority, not the majority.
The Common Belief
$148,153. That's the average 401(k) balance in America right now, and it's the number that gets repeated at dinner tables and in retirement calculators as if it describes a typical worker. As of July 19, 2026, according to 24/7 Wall St. — via Google News — that average sits next to a much less flattering figure: a median of $38,176. Same country, same year, two numbers nearly $110,000 apart. One of them is doing a lot of quiet work to make American retirement savings look healthier than they are.
The common belief goes something like this: if the average 401(k) is approaching $150,000, most people in their 40s and 50s are probably sitting on a decent nest egg. Financial media reinforces it by leading with the average because it's the bigger, more optimistic number. Vanguard's How America Saves 2024 report — which analyzed 5 million participants — found an average balance of $134,128 for 2023. Fidelity's Q3 2024 figures put the average at $132,300, a 23% jump year-over-year, fueled largely by S&P 500 gains exceeding 20%. Every headline number points the same direction: up, up, up.

Where It Breaks Down
Here's the problem: an average gets dragged upward by a small number of very large accounts, the same way a room's average income jumps the moment a billionaire walks in. As of July 19, 2026, according to Vanguard's 2024 data, only about 14% of participants have balances above $250,000 — meaning the bulk of the "average" is being generated by a minority of high earners with decades of compounding and maxed-out contributions behind them.
The median tells a different, more honest story, because it isn't distorted by outliers — it's simply the middle value when every account is lined up smallest to largest. And the median sources don't fully agree with each other either, which is its own useful data point. 24/7 Wall St. reports a median of $38,176, while Vanguard's own report cites $35,286 — a gap likely explained by different participant pools and reporting periods (year-end versus Q3). Fidelity, for its part, doesn't publish an identical median figure alongside its $132,300 average, which is itself lower than 24/7 Wall St.'s average — another reminder that "the 401(k) balance" depends heavily on which recordkeeper and which quarter you're citing.
Age widens the gap further. Workers 65 and older average more than $200,000, while workers under 25 average less than $7,000 — which makes sense, since compounding needs time more than it needs luck. But even the group closest to retirement isn't reassuring: Americans aged 55-64 have a median 401(k) balance of approximately $61,530, a figure that research data describes as far below retirement adequacy benchmarks. That's the number that should actually worry people — not the $148,153 headline.

A Better Frame
Financial advisors consistently recommend using the median, not the average, to benchmark personal retirement readiness — and the math explains why. The goal isn't to match the average; it's to know where your own balance sits relative to people in a similar position, then work the actual numbers from there. A 401(k) doesn't grow because a headline average went up 23%; it grows because a real return — often modeled around 7% after inflation — gets compounded, year after year, on money that's actually going in.
That's where the habit side of this matters more than the statistics. The average contribution rate across all participants is 7.4%, and once employer matching is factored in, the effective savings rate climbs to about 11.7%. That's the mechanism that turns a $38,176 median into something closer to a six-figure balance over time — not a single good year in the market, but a consistent, automated contribution that doesn't depend on remembering to do it. The SECURE 2.0 Act's automatic enrollment provisions, rolling out in 2024-2025, were built around exactly this insight: participation, not conviction, is what closes the gap for lower-income workers.
AI-driven tools are starting to play a supporting role here too. Robo-advisors and automated rebalancing features — increasingly built into 401(k) platforms from providers like Fidelity and Vanguard — can optimize asset allocation for participants who don't have the time or expertise to do it manually, functioning as a kind of investment portfolio autopilot. Adoption still skews toward higher-income savers, but the tools exist for everyone with an account.
Our read: the persistent gap between the average and the median isn't a temporary market quirk — it's a structural feature of how compounding rewards consistency and time, and it will keep showing up in these reports as long as contribution rates and participation stay uneven across income levels. The more useful exercise for financial planning isn't chasing the $148,153 headline; it's automating a contribution rate today and letting the math — not the news cycle — do the rest.
Frequently Asked Questions
Why is the average 401(k) balance so much higher than the median?
Because a small share of accounts — about 14% of participants have balances above $250,000, per Vanguard's 2024 data — pull the average sharply upward, while the median reflects the typical saver unaffected by those high-balance outliers.
What is a good 401(k) balance by age?
There's no single universal target, but research shows workers under 25 average less than $7,000, while those 65 and older average more than $200,000; the median for ages 55-64 is roughly $61,530, a figure described as running behind typical retirement adequacy benchmarks.
How much should I have in my 401(k) at age 50?
The closest available benchmark is the 55-64 median of about $61,530 — and advisors generally treat that figure as a warning sign rather than a target, since it falls well short of what most retirement adequacy models call for at that stage of a career.
Is $100,000 in a 401(k) good for retirement?
It's well above the reported median of $38,176 (or $35,286 per Vanguard) but still below the $148,153 average and short of the roughly $250,000 threshold that only about 14% of participants have crossed — a solid position relative to peers, but not yet in the top tier.
