What Your Average 401(k) Balance by Age Really Means

The average 401(k) balance across Vanguard‘s retirement plans was $167,970 at the end of 2025. The median — the account sitting right in the middle — was $44,115. That gap between the two numbers is the whole story of this page.

If you just checked your balance and felt behind, you were probably comparing yourself against the average, and the average is misleading. Where you actually stand depends on your age, so this guide breaks the data down by age band and gives you the median for yours.

Read it based on where you are. In your 20s or 30s, focus on the early-age rows and why starting small still works. At 45 or older and worried about catching up, the reality-versus-benchmark section and the contribution limits matter most. As a higher earner, the income breakdown will land closest to home.

Average and median 401(k) balance by age

Here is the 401(k) balance by age, showing both the average and the median for each group, from Vanguard’s year-end 2025 data.

How your age band compares

Balances climb steadily with age, which makes sense: more years of contributions, more time for compounding, and usually higher income. The median balance rises from $2,234 for workers under 25 to $107,269 for the 55–64 group.

Notice the slight dip at 65 and older. Once people retire, contributions stop and withdrawals begin, so the median edges down even as the oldest, largest accounts keep the average high.

What a good balance looks like at 40, 50, and 60

For a saver in their early 40s, the 35–44 median is $46,919. In their early 50s, the 45–54 median is $78,730. Approaching 60, the 55–64 median is $107,269.

Treat these as reference points, not report cards. A “good” balance is one that’s on track for your retirement plan — which the later sections help you gauge.

Why the average 401(k) balance is misleading

The average 401(k) balance sits far above the median because a small number of very large accounts pull the mean upward. Vanguard’s $167,970 average lands at roughly the 75th percentile — meaning about three in four participants have less.

🔍 How It Works: The average adds up every account and divides by the number of accounts, so a handful of seven-figure balances drags it up. The median instead finds the middle account — half of savers are above it, half below — which is why it better reflects a typical balance.

Average vs. median, explained

Vanguard’s own analysis notes that averages lean toward participants who are older, longer-tenured, or higher-income. The distribution shows it plainly: roughly 1 in 4 participants held less than $10,000, while 18% held $250,000 or more.

The same mean-versus-median gap runs through household wealth generally, as the Federal Reserve’s Survey of Consumer Finances documents. And not everyone even has a plan — retirement benefit access ranged from 59% of private-industry workers at the smallest firms to 90% at the largest as of March 2025, according to the Bureau of Labor Statistics. Participant-based benchmarks don’t capture workers with no access at all.

Why Vanguard and Fidelity report different numbers

You’ll see different figures depending on the recordkeeper. Fidelity’s Q4 2025 analysis put the average 401(k) balance at $146,400 and the median at $34,400 — both below Vanguard’s.

Neither is more accurate. Vanguard administers more large-employer plans skewed toward higher earners, while Fidelity’s broader mix of plan sizes pulls both numbers down. They’re snapshots of different slices of the same workforce.

How much you should have saved — reality vs. the rule of thumb

The most cited savings benchmark comes from Fidelity: aim for 1x your salary saved by 30, 3x by 40, 6x by 50, 8x by 60, and 10x by 67.

• By age 30: 1x your salary
• By age 40: 3x your salary
• By age 50: 6x your salary
• By age 60: 8x your salary
• By age 67: 10x your salary

Here’s the catch those tables rarely mention: Fidelity’s targets count all your retirement savings and assume you save about 15% of income every year from age 25. The Vanguard medians above are 401(k) balances only. The two aren’t measuring the same thing.

The income effect

Income is the single strongest predictor of your balance, and the spread is wide.

Source: Vanguard, How America Saves 2026 (year-end 2025).

Below $30,000, the median 401(k) balance falls under $7,000 — a reflection of tighter cash flow and lower plan access, not weaker discipline.

Worked example: reconciling the median with the target

Take a 45-year-old earning $80,000. Fidelity’s rule of thumb suggests 3x–4x salary saved — roughly $240,000 to $320,000. The real 45–54 median is $78,730.

That gap looks alarming until you read it correctly. The Fidelity figure is an aspirational, all-accounts target that assumes a lifelong 15% savings rate; the median is where actual 401(k) balances sit. If your balance falls between the median and the average for your age, you’re already ahead of most of your peers.

✅ Action Step: Before deciding you’re behind, add up every retirement account you hold — current 401(k), old 401(k)s, and IRAs — and compare that total against the Fidelity multiple for your age. A compound interest calculator shows what raising your contribution by even one or two percentage points does over 20 years, and our guide on how much to contribute to your 401(k) turns the gap into a number.

What changed in 2025 — and how much you can contribute now

You can contribute up to $24,500 to a 401(k) in 2026 — the standard elective deferral limit set by the IRS. If you’re 50 or older, you can add an $8,000 catch-up, for $32,500 total.

There’s a larger tier for one narrow window: workers who are 60, 61, 62, or 63 during 2026 can add $11,250 instead, for $35,750. Combined employee-and-employer contributions can reach $72,000. You can review the IRS’s 2026 contribution limits directly, or our full breakdown in the pillar guide to 2026 contribution limits, match, and payouts.

Why balances hit records in 2025

The record balances were mostly a market story, not a savings surge. Stocks and bonds both had a strong year, and the average one-year participant return across Vanguard plans was 19.3%.

Contribution behavior held flat. The average employee deferral was 7.6% of pay, and only 14% of participants hit the maximum. A balance on any single day mostly reflects where the market was that day.

2026 contribution limits and catch-up rules

One rule is new for 2026. If your prior-year wages from your employer topped $150,000, your catch-up contributions must now go into a Roth account rather than pre-tax — the details are in our explainer on the Roth catch-up rule for high earners.

For everyone 50 and up, catch-up contributions are the fastest lever to lift a below-median balance, when the cash flow is there.

⚠️ Costly Mistake: Assuming a strong market year means you’re on track. A 19% gain reflects the market, not your saving — and if you cut contributions because your balance looks healthy, you give up the one input you actually control.

What your balance means for retirement readiness

A 401(k) balance is a starting point, not a grade. It only becomes meaningful when you measure it against what you plan to spend.

Turning a balance into income: a rough frame

As a rough illustration, one common rule of thumb withdraws about 4% of a balance in the first year of retirement. Applied to the 55–64 median of $107,269, that’s roughly $4,300 a year — a reminder that a 401(k) alone rarely funds a full retirement.

That’s not a verdict on anyone. It’s a prompt to see the whole picture, including Social Security, pensions, and other savings. You can model your own figures with a 401(k) calculator and a broader retirement calculator.

The variables only you can fill in

Your retirement age, expected spending, Social Security timing, other assets, and the order in which you draw down accounts all change the answer. No single benchmark captures them.

✅ Action Step: Ask a fiduciary (fee-only) financial advisor one focused question: “Given my age, savings rate, other assets, and target retirement age, am I on track, and what one change would matter most?” For age-specific tactics, see our guide to retirement savings strategies by age.

Encouragingly, most savers don’t cash out when they leave a job — 97% of assets available for distribution in 2025 stayed invested. Sustained over years, that habit matters more than any single year’s balance.

Common 401(k) mistakes that keep balances below the median

A below-median balance often traces to a few avoidable errors, not a lack of discipline.

Leaving the employer match on the table

The most expensive mistake is not contributing enough to capture the full employer match. That’s an immediate return on your money, and skipping it is exactly why we treat the match as free money you shouldn’t leave behind.

A second, quieter drag is staying at a low automatic-enrollment default rate for years without ever raising it.

Treating your 401(k) as an emergency fund

Hardship withdrawals are rising. About 6% of Vanguard participants took one in 2025 — up from roughly 5% the year before, and part of four straight years of increases.

The typical withdrawal was small, which suggests these are emergency stopgaps rather than large raids. Still, money pulled out early stops compounding, and a 401(k) doing double duty as an emergency fund is a signal to build a separate cash cushion.

💡 Expert Note: A common point of confusion is treating a 401(k) loan or hardship withdrawal as “borrowing from yourself” at no cost. The real cost is the growth those dollars would have earned while invested — which, over a decade or two, usually dwarfs the amount withdrawn.

Frequently asked questions

The bottom line on your 401(k) balance

Compare yourself to the median for your age, not the headline average. The average is skewed by the wealthiest accounts, and measuring against it makes most savers feel further behind than they really are.

Then treat your balance as a starting point. Add up all your retirement accounts, weigh them against a realistic target, and run your own numbers.
