The Average 401(k) Is $167,970. The Median Is $44,115. One of Those Numbers Is Misleading You.

Vanguard’s latest How America Saves report puts the average 401(k) balance at $167,970, a record high. The median sits at $44,115. That gap frames the rest of the data.

Averages get pulled around by outliers. If ten people have $5,000 saved and one walks into the room with $5 million, the median stays at $5,000 while the mean jumps to about $459,000. The 401(k) numbers work the same way. A relatively small group of long-tenured, high-income savers sitting on very large balances pulls the national average up toward $168,000. The median is what a person in the middle of the distribution actually has.

Why the Average Is Doing So Much Work

Vanguard’s own account data reveals just how lopsided the distribution really is. Only 10% of participants have balances of $250,000 or more, and within that top tier, the average sits at $549,281. On the opposite end, 8% of savers have accumulated less than $10,000, with an average of just $7,919. That top group is small but holds an outsized share of total dollars, which pulls the overall average upward.

Fidelity’s platform, which covers 24.8 million participants across 26,200 corporate defined contribution plans, tells the same story from a different perspective. Savers who stay the course come out far ahead. More than 5.5 million individuals who remained in the same 401(k) plan with the same employer for five consecutive years ended 2025 with an average balance of $304,200. Plan continuity, combined with consistent contribution rates, appears to be doing the heavy lifting.

Balances by Generation Tell a Cleaner Story

Breaking the average down by age removes some of the distortion. Fidelity’s Q4 2025 figures:

• Boomers: $270,800
• Gen X: $222,100
• Millennials: $83,700
• Gen Z: $17,900

Why the Median Is Stuck

Saving is competing with a rising cost of living. Average annual household spending reached $78,535 in 2024, up from $72,973 in 2022. The personal savings rate has moved in the other direction, falling to 2.8% in the second quarter of 2026 from 6.2% at the start of 2024. When less money is left over at the end of the month, deferral rates stay modest, and account growth relies on market returns rather than fresh contributions.

Access to a plan matters, too. 80% of college graduates have a retirement account, compared with 37% of adults with no college experience. The median 401(k) figure reflects only people who already have one; a large share of workers is not in the sample at all.

Levers That Move the Median

1. Capture the full employer match. Vanguard’s average total contribution rate, employee plus employer, is 12%, short of Fidelity’s suggested 15%. Closing that gap is often the difference between a match earned and one left on the table.
2. Use catch-up contributions after 50. The 2026 standard deferral cap is $24,500, with an $8,000 catch-up for workers 50 and older, for a total of $32,500. Workers 60 to 63 can add up to $11,250, for a total of $35,750.
3. Note the new Roth rule. Starting in 2026, employees 50 and older who earned more than $150,000 in 2025 must direct catch-up contributions to a Roth 401(k). Take-home pay drops in the short term, though withdrawals in retirement are tax-free.

The $167,970 headline is real. It is also an artifact of how averages behave when a small group holds a very large share of the dollars. The $44,115 median is a closer read on where a typical saver actually stands, and by most retirement-adequacy yardsticks, it is well short of the finish line. The old 4% rule that anchors most of those yardsticks has its own problems, which we walked through in a free report on why the rule wobbles and what to run instead.
