Average 401(k) Balance by Age in 2026: How Do You Compare?
See the average and median 401(k) balance by age in 2026 from Vanguard and Fidelity data, and learn how to tell whether your retirement savings are actually on track.
Wondering whether your retirement savings measure up? Looking at the average 401(k) balance by age is one of the fastest ways to see where you stand, but the number that matters most depends on which data set you use and whether you look at the average or the median. Here’s what the latest 2026 data from Vanguard and Fidelity actually shows, and how to use it without falling into the comparison trap.
Average 401(k) Balance by Age: Vanguard 2026 Data
According to 2026 retirement savings data drawing on Vanguard’s recordkeeping, average 401(k) balances range from $7,259 for workers under 25 to $330,186 for those 65 and older. But the median tells a very different story: just $2,234 for workers under 25 and $103,202 for those 65 and older. That gap between average and median exists because a small number of high earners with very large balances pull the average sharply upward.
| Age Group | Average Balance | Median Balance |
|---|---|---|
| Under 25 | $7,259 | $2,234 |
| 65 and older | $330,186 | $103,202 |
Average 401(k) Balance by Generation: Fidelity 2026 Data
Fidelity Investments’ Q1 2026 data breaks balances down by generation instead of narrow age bands. Overall, Americans have about $141,000 saved in their 401(k)s on average. By generation:
- Baby Boomers: $260,300 average balance
- Gen X: $215,600 average balance
- Millennials: $82,600 average balance
- Gen Z: $18,000 average balance
Why Vanguard and Fidelity Numbers Differ
Vanguard administers a higher concentration of large-employer retirement plans, which tend to be skewed toward higher-income participants with bigger balances. Fidelity’s client base spans a broader mix of plan sizes and employers, which pulls its averages down closer to what a typical American worker actually has saved. Neither number is wrong; they’re just measuring somewhat different populations.
Average vs. Median: Which Should You Compare Yourself To?
The median is almost always the more useful benchmark for an individual. When you compare your balance to the average, you’re really measuring yourself against people in the top quarter of savers, since a relatively small number of very large balances distort that number upward. The median balance reflects the person exactly in the middle of the distribution, which is a much fairer comparison for most workers.
How to Tell If You’re on Track
A commonly cited rule of thumb is to have saved roughly one times your salary by 30, three times by 40, six times by 50, and eight times by 60. These targets assume steady contributions and consistent market returns, so treat them as a directional guide, not a strict requirement. If you’re behind, increasing your contribution rate even by 1% to 2% of salary, especially if it captures a full employer match, can meaningfully close the gap over a decade or more thanks to compounding.
401(k) vs. Roth IRA: Where Should New Savings Go?
Once you’re contributing enough to get your full employer match, the next question is usually whether additional savings should go into your 401(k) or a Roth IRA. Each has different tax treatment and contribution limits, and the right choice depends on your current versus expected future tax bracket. Our full breakdown of 401(k) vs. Roth IRA walks through how to decide which account to fund first.
Starting Late or Starting Small
If your balance is well below these benchmarks, you’re far from alone, and starting now still matters more than starting perfectly. Even modest, consistent contributions from your very first paycheck can compound significantly over a career. If you’re just getting going, our guide to investing with your first paycheck covers the basics of building the habit early.
2026 401(k) Contribution Limits
Your balance grows fastest when you’re able to contribute close to the annual maximum. According to the IRS, the standard employee contribution limit for 401(k) plans rises to $24,500 in 2026, up from $23,500 in 2025. Workers 50 and older can add a catch-up contribution of $8,000, for a total of $32,500, while those aged 60 to 63 get an enhanced catch-up limit of $11,250 under SECURE 2.0 rules. Starting in 2026, higher earners who made more than $150,000 the prior year must make catch-up contributions on a Roth basis rather than pre-tax.
Frequently Asked Questions
What is the average 401(k) balance in 2026?
Overall, Americans have about $141,000 saved in their 401(k)s on average as of Fidelity’s Q1 2026 data, though this varies significantly by age and generation.
What is a good 401(k) balance for my age?
A common rule of thumb targets one times your annual salary saved by age 30, three times by 40, six times by 50, and eight times by 60, though individual circumstances vary widely.
Why is the average 401(k) balance so much higher than the median?
A relatively small number of savers with very large balances pull the average upward, while the median reflects the person exactly in the middle of all savers, making it a more representative benchmark.
How much do Millennials have saved in their 401(k)s?
Fidelity’s Q1 2026 data shows Millennials have an average 401(k) balance of $82,600.
How much do Baby Boomers have saved in their 401(k)s?
Baby Boomers have an average 401(k) balance of $260,300, according to Fidelity’s Q1 2026 data, the highest of any generation.
Is it too late to start saving for retirement in my 40s or 50s?
No. While starting earlier gives compounding more time to work, increasing your contribution rate in your 40s or 50s, especially by maximizing catch-up contributions, can still meaningfully improve your retirement outlook.
Should I prioritize my 401(k) match over paying off debt?
Most financial professionals suggest contributing at least enough to capture your full employer match before aggressively paying down lower-interest debt, since the match is essentially an immediate 100% return.
Does the average 401(k) balance include employer contributions?
Yes. Reported 401(k) balances typically include both employee contributions and any employer matching or profit-sharing contributions, plus investment growth.
How often should I check my 401(k) balance against these benchmarks?
Once or twice a year is generally sufficient. Checking too frequently can lead to reacting emotionally to normal market fluctuations rather than focusing on your long-term contribution rate.
Do these balances account for people with multiple retirement accounts?
No. Vanguard and Fidelity’s figures reflect balances held in accounts administered by that specific company, so someone with 401(k)s at multiple past employers may have higher total retirement savings than a single account suggests.
