The latest age-band figures found are Fidelity’s Q2 2026 data, measured as of March 31, 2026. Average balances range from $7,700 for ages 20–24 to $264,500 for participants age 70 and older. These are provider-specific account averages—not a national standard or a personal retirement-readiness test.

Fidelity average 401(k) balance by age

Fidelity’s table covers 26,800 corporate defined-contribution plans and 25.6 million participants. It includes the advisor-sold market, but excludes the tax-exempt market, nonqualified defined-contribution plans and Fidelity’s own employee plans. The figures are account averages from that defined population, not a census of every U.S. worker or all retirement assets. Fidelity methodology and age table

Age Average 401(k) balance
20–24 $7,700
25–29 $26,600
30–34 $51,700
35–39 $81,600
40–44 $120,100
45–49 $163,200
50–54 $215,700
55–59 $260,800
60–64 $257,400
65–69 $258,800
70+ $264,500

The small decline from ages 55–59 to 60–64 does not imply that every participant’s account fell; market returns, withdrawals, contributions and the mix of people in each band all affect an average.

Vanguard average and median balances

Vanguard’s How America Saves 2025 uses year-end 2024 data from nearly 5 million participants in its defined-contribution business. Because Vanguard reports both measures, its median helps show what a middle participant had, while the average is pulled upward by very large accounts. Vanguard age table and methodology

Age Average Median
Under 25 $7,351 $2,816
25–34 $37,557 $14,933
35–44 $91,281 $35,537
45–54 $168,646 $60,763
55–64 $244,750 $87,571
65+ $272,588 $88,488

Vanguard’s overall figures were a $148,153 average and a $38,176 median. The average exceeds the median in every age band, so comparing your account only with an average can make a typical saver appear behind.

Why the numbers are not interchangeable

  • Different dates: Fidelity’s age table is as of March 31, 2026; Vanguard’s table uses year-end 2024 observations.
  • Different populations: Each provider analyzes its own defined-contribution plan participants and exclusions.
  • Different age bands: Fidelity uses mostly five-year bands, while Vanguard uses broader ranges.
  • Different statistics: Fidelity’s listed age figures are averages; Vanguard supplies both averages and medians.

Use one series consistently when tracking change. Do not combine a Fidelity age band with a Vanguard band as if they were a matched national benchmark.

Does your balance mean you are on track?

Age alone cannot answer that. A useful comparison also includes your income, years contributing, contribution rate, employer contributions, expected retirement age, spending plans and savings outside the 401(k). A person with a smaller 401(k) may have substantial IRA, brokerage, real-estate, cash, certificate-of-deposit or health-savings-account assets; a larger balance may still be insufficient for an early retirement or high spending.

Use a personal progress checklist

  • Record your current 401(k) balance and whether the account is traditional, Roth or both.
  • Calculate your total annual contribution, including the employer match.
  • Compare that percentage with your pay and with the number of years until retirement.
  • List other retirement and non-retirement assets and any debts that will affect future spending.
  • Estimate the retirement age and annual expenses your savings must support.
  • Review the plan’s investment mix, fees, vesting rules and beneficiary designation.

Provider savings guidelines

Fidelity describes a general target of saving 15% of annual income, including employer contributions and other retirement accounts. Vanguard gives a broad 12%–15% guideline, also including employer contributions. These are rules of thumb, not individualized advice; a later retirement date, pension, unusually high expenses or a different savings horizon can change the appropriate rate.

What recent market data adds

Fidelity’s Q1 2026 analysis reported a $141,000 average 401(k) balance, down 4% from Q4 2025 but up 11% from Q1 2025. It also reported a 14.4% combined 401(k) savings rate. That quarterly aggregate is a separate, newer population cut from Fidelity’s age table, so it should not be treated as an age-specific benchmark. Balances can move with markets, contributions and withdrawals. Fidelity Q1 2026 analysis

How to use an age benchmark responsibly

  1. Choose a table whose provider, date and age range resemble your situation.
  2. Check whether it reports an average, median or both.
  3. Compare your savings rate and years remaining—not just the dollar balance.
  4. Add every account and expected income source that can fund retirement.
  5. Adjust contributions and investment choices to your plan, risk tolerance and timeline.
