The headline number from Vanguard’s 2025 How America Saves report looks reassuring at first glance: the average 401(k) account balance reached $148,153 in 2024. That figure suggests the typical American worker is sitting on a six-figure retirement nest egg. The median tells a different story. The median balance, the one that actually describes the worker in the middle of the distribution, was $38,176. The roughly $110,000 gap between those two numbers reflects the distribution of balances.
Why the Average Distorts
A simple illustration explains the distortion. If 10 people each have $5,000 saved and one person walks in with $5 million, the median balance is still $5,000. The average jumps to roughly $459,000. Nothing changed for the typical saver, but the headline number now suggests everyone is wealthy.
The same dynamic plays out in 401(k) data. Vanguard explicitly notes that the median “represents the typical participant: Half of all participants had balances above the median, and half had balances below.” The average, by contrast, “is indicative of participants at about the 75th percentile”, meaning roughly 75% of workers have balances below it.
Where the Skew Comes From
The 6% Stress Test: Hardship on the Rise
While average balances look healthy, the underlying stability of these accounts is wavering. New data for 2026 shows that hardship withdrawals have hit a record high of 6%—triple the pre-pandemic average. Among those tapping their funds, 35% cited the need to prevent foreclosure or eviction.
This “leakage” suggests that for a growing segment of the workforce, the 401(k) is no longer just a retirement vehicle; it is functioning as a high-stakes emergency fund. While the market’s strength keeps the “average” high, these withdrawals highlight the fragility of the median worker’s financial safety net.
Reading Your Real Number (Median vs. Average by Age)
To find where you actually stand, you must look at age-specific data. The “Illusion” of the average is most apparent in older brackets, where high-balance “super-savers” pull the mean far away from reality.
| Age Group | Median Balance (The Real Number) | Average Balance (The Illusion) |
|---|---|---|
| Under 25 | $1,948 | $6,899 |
| 35–44 | $39,958 | $103,552 |
| 55–64 | $95,642 | $271,320 |
| 65+ | $88,488 | $272,588 |
New 2026 Rules for High Earners
The gap between the “haves” and “have-nots” is also being reshaped by the SECURE 2.0 Act. Starting in the 2026 tax year, participants aged 50+ who earned more than $145,000 in the previous year are now mandated to make their catch-up contributions to Roth (after-tax) accounts. This removes the immediate tax-deferral benefit for the very group currently driving the “Average” balance higher, fundamentally changing long-term tax planning for the top 16% of savers.
Reference Points
- The 2026 IRS deferral limit has increased to $24,500.
- The “Super Catch-Up”: Workers aged 60–63 can now contribute an additional $11,250, bringing their total potential annual contribution to $35,750.
- Vanguard’s data shows tenure remains the ultimate divider: Participants with 10+ years in their plan average $324,510, while those with under two years have a median of just $6,140.
