Average 401(k) Balance by Age in 2026: How Do You Compare to Your Peers?
The average 401(k) balance by age in 2026 ranges from just $7,259 for workers under 25 to $330,186 for those 65 and older, according to Vanguard’s latest participant data. But averages can be misleading — the median balance, which better reflects what a typical saver actually has, is often less than a third of that number. If you’ve ever wondered how your retirement savings stack up against your peers, this guide breaks down the real numbers by age group, generation, and income level, using the most current data from Vanguard, Fidelity, and the Federal Reserve.
Average 401(k) Balance by Age in 2026
Vanguard’s How America Saves report, based on roughly 4.6 million participant accounts, puts the overall average 401(k) balance at year-end 2025 at $167,970, with a median of just $44,115. That gap between average and median exists because a relatively small number of high earners with large balances pull the average upward, while most savers cluster closer to the median.
| Age Group | Average Balance | Median Balance |
|---|---|---|
| Under 25 | $7,259 | $2,234 |
| 25–34 | ~$37,000 | $18,732 |
| 35–44 | ~$91,000 | $46,919 |
| 45–54 | ~$168,000 | ~$68,000 |
| 55–64 | ~$244,000 | ~$92,000 |
| 65 and older | $330,186 | $103,202 |
The takeaway: don’t panic if your balance sits below the average for your age group. The median is the more honest benchmark, since it isn’t skewed by a handful of very large accounts.
Average 401(k) Balance by Generation
Fidelity’s Q1 2026 data, drawn from 26,800 corporate retirement plans and 25.6 million participants, breaks balances down by generation instead of strict age bands:
- Gen Z: $18,000 average
- Millennials: $82,600 average
- Gen X: $215,600 average
- Baby Boomers: $260,300 average (plus an average IRA balance of $286,700)
Fidelity also found that overall savings rates — combining employee and employer contributions — hit an all-time high of 14.4% in early 2026, suggesting more workers are taking retirement saving seriously even amid ongoing inflation pressure.
Why Staying in One Plan Longer Pays Off
One of the most striking findings in Fidelity’s research is the impact of plan tenure. Millennials who stayed in the same 401(k) plan for at least five years had average balances of $180,200 — more than double the overall millennial average of $82,600. Gen X workers who stuck with one plan for 15 years averaged nearly $649,000, and long-tenured baby boomers topped $576,000. Job-hopping without rolling over old accounts, or cashing out balances when switching jobs, is one of the biggest drags on long-term retirement wealth.
2026 Contribution Limits: How Much You Can Save
The IRS raised 401(k) contribution limits for 2026. Employees can now defer up to $24,500 of their salary into a 401(k), up from $23,500 in 2025. Workers age 50 and older can add a catch-up contribution of $8,000, bringing their total to $32,500. A special higher catch-up limit of $11,250 applies to savers ages 60 through 63, allowing them to contribute up to $35,750 total. Combined employee and employer contributions are capped at 100% of compensation or $72,000, whichever is lower ($80,000 for those eligible for catch-up contributions).
How to Tell If You’re On Track
Most retirement guidance suggests aiming for a multiple of your salary saved by certain ages: roughly 1x by 30, 3x by 40, 6x by 50, 8x by 60, and 10x by 67. These benchmarks are rough guides, not guarantees — your actual target depends on when you want to retire, expected Social Security income, and your planned lifestyle. If you’re behind, increasing your contribution rate by even 1-2% now, especially if it captures a full employer match, can meaningfully change your trajectory over a 20-30 year horizon thanks to compound growth. If you want to see how compounding actually plays out over decades, our guide on how compound interest can make you rich walks through the math.
Closing the Gap If You’re Behind
If your balance is below the median for your age group, a few moves tend to make the biggest difference: capturing the full employer match (it’s free money), automatically escalating your contribution rate by 1% each year, consolidating old 401(k)s from previous jobs instead of leaving them scattered or cashing them out, and reviewing your investment mix to make sure it matches your actual time horizon rather than sitting too conservatively in cash. For those just getting started with investing outside of a workplace plan, our step-by-step guide to investing in 2026 covers the basics of opening an account and choosing investments. According to the U.S. Bureau of Labor Statistics, roughly 56% of private industry workers had access to an employer-sponsored retirement plan in 2025, so if you have access but aren’t enrolled, that’s the first gap worth closing.
Retirement savings benchmarks are useful for a gut check, but the number that matters most is your own trajectory: are you contributing more this year than last, and is that gap between average and median closing for you personally? Small, consistent increases compounded over decades matter far more than hitting an arbitrary number at any single age.
Frequently Asked Questions
What is the average 401(k) balance by age in 2026?
According to Vanguard, average balances range from $7,259 for workers under 25 to $330,186 for those 65 and older, with an overall average of $167,970 across all ages as of year-end 2025.
What is a good 401(k) balance for my age?
A common rule of thumb is to have 1x your salary saved by 30, 3x by 40, 6x by 50, 8x by 60, and 10x by 67, though your personal target depends on your retirement timeline and expected expenses.
Why is the median 401(k) balance so much lower than the average?
A relatively small number of high-balance accounts pull the average upward. The median, which represents the middle value in the data set, isn’t distorted by those outliers and better reflects what a typical saver has.
What is the 2026 401(k) contribution limit?
The IRS set the 2026 employee deferral limit at $24,500, with an additional $8,000 catch-up contribution allowed for those 50 and older ($11,250 for ages 60-63).
How much does the average American have saved for retirement by age 40?
Vanguard data shows a median 401(k) balance of about $46,919 for the 35-44 age bracket, though this varies significantly by income and how long someone has been contributing.
Do Millennials have enough saved in their 401(k)s?
Fidelity reports an average Millennial 401(k) balance of $82,600, but those who stayed in the same plan for at least five years averaged $180,200 — more than double, showing how much tenure and consistency matter.
What happens to my 401(k) balance if I change jobs?
You can typically leave it with your former employer’s plan, roll it into your new employer’s 401(k), or roll it into an IRA. Cashing it out early usually triggers taxes and a 10% penalty before age 59½, and interrupts compound growth.
How much should I contribute to my 401(k) each year?
Most financial guidance recommends contributing at least enough to get the full employer match, then working toward saving 15% of income annually (including employer contributions) for retirement.
What percentage of workers have access to a 401(k) plan?
The U.S. Bureau of Labor Statistics reported that about 56% of private industry workers had access to an employer-sponsored retirement plan in 2025.
Are 401(k) balances actually increasing in 2026?
Yes. Fidelity reported total savings rates (employee plus employer contributions) reached an all-time high of 14.4% in early 2026, and Gen Z and Millennial balances have shown some of the fastest year-over-year growth.
