Fidelity’s latest age-specific figures put the average 401(k) balance at $215,700 for people ages 50–54 and $260,800 for ages 55–59, based on participant data through March 31, 2026. Those are averages from Fidelity’s plan population—not universal retirement targets. Vanguard’s published figures show why the distinction matters: its median balances are far below its averages.
Average 401(k) balance by age in your 50s
Fidelity Investments reports these averages from Q2 2026 data, measured as of March 31, 2026:
| Age | Average 401(k) balance |
|---|---|
| 50–54 | $215,700 |
| 55–59 | $260,800 |
Fidelity says the data cover 26,800 corporate defined-contribution plans and 25.6 million participants. The figures include the advisor-sold market and exclude the tax-exempt market; certain plan categories and Fidelity employees are excluded from behavioral statistics. These are account balances among participants in Fidelity’s dataset, not a census of all Americans in those age groups. Fidelity’s age-by-age retirement savings data were published June 23, 2026.
Why another source may show a different average
Vanguard’s How America Saves 2026 reports 2025 data for its own defined-contribution plan participants. Its age bands are broader than Fidelity’s and it publishes both averages and medians:
#1 Best Overall
| Age band | Average balance | Median balance |
|---|---|---|
| 45–54 | $214,991 | $78,730 |
| 55–64 | $305,006 | $107,269 |
The average is the arithmetic mean; the median is the midpoint account in a dataset. In Vanguard’s figures, the average is substantially higher than the median, indicating that larger accounts pull the mean upward. A person comparing their balance with an average may therefore be comparing themselves with a figure that is not typical of the middle participant. Vanguard’s numbers are not a nationwide count of every household or every retirement asset. See Vanguard’s How America Saves reports.
The two providers should not be treated as interchangeable or averaged together. They use different participant populations, age bands, and data periods; the cited figures describe their respective recordkeeping datasets.

What a peer comparison can—and cannot—tell you
A balance comparison is a rough point of reference, not a retirement-readiness test. A 401(k) statement does not show the whole financial picture: you may also have an IRA, another workplace plan, taxable savings, or a pension. Household income needs, the age you plan to retire, and how long assets must support you also affect whether your savings are sufficient. Fidelity notes that retirement and other savings can be held in multiple types of accounts.
Use the benchmark to prompt a more personal review, rather than to declare yourself ahead or behind. A useful review includes:
Rank #3
- Other resources: List retirement accounts, taxable investments, and any pension benefits alongside the 401(k).
- Contribution and match: Check your current contribution rate and whether you are receiving the full employer match available under your plan.
- Retirement assumptions: Estimate the income you may need and the date you hope to stop working, then model how your savings could support that plan.
Contribution benchmarks and 2026 catch-up rules
Fidelity reports an average 401(k) savings rate of 14.4% in Q2 2026, made up of 9.6% employee contributions and 4.8% employer contributions. Fidelity suggests a combined annual savings rate of 15%; that is the provider’s guideline, not a guarantee that any particular person will have enough to retire. Your employer contribution, pay, time horizon, and retirement needs all matter. Details appear in Fidelity’s Q2 2026 retirement analysis.
For 2026, Vanguard’s investor guidance lists a $24,500 employee 401(k) contribution limit and an additional $8,000 catch-up contribution for eligible participants age 50 or older. It also describes an enhanced catch-up for eligible participants ages 60–63. These annual limits are subject to eligibility and plan implementation; check current IRS guidance and your plan’s rules before changing contributions.
