How Much Should You Have in Your 401(k) by Age 30, 40, and 50?
"Am I behind?" is the single most common question people have about retirement savings. It's also the wrong question to obsess over — but it's a useful starting point, because having a benchmark turns a vague anxiety into a number you can actually act on. So let's put real figures on the table.
Two things to understand before the numbers: benchmarks are guidelines, not verdicts, and your savings rate matters more than your current balance. A 32-year-old saving 15% of their income is in better shape than a 32-year-old with a bigger balance who just stopped contributing. With that caveat in place, here's the framework most planners actually use.
The Fidelity Benchmark: Multiples of Your Salary
The most widely cited rule of thumb comes from Fidelity, and it's expressed as a multiple of your annual salary rather than a flat dollar amount — which is smart, because $500,000 means something very different to someone earning $50,000 than to someone earning $150,000.
- By age 30: 1× your annual salary saved
- By age 40: 3× your salary
- By age 50: 6× your salary
- By age 60: 8× your salary
- By age 67: 10× your salary
So if you earn $70,000, the benchmark suggests roughly $70,000 saved by 30, $210,000 by 40, and $420,000 by 50. These targets assume you save about 15% of income annually (including any employer match), invest in a diversified mix weighted toward stocks when young, and retire around 67.
Reality check: These are aspirational targets, not averages. Most Americans fall short of them — and the benchmarks assume you'll want to maintain your pre-retirement lifestyle. If you plan to spend less in retirement, you can aim lower.
What People Actually Have (vs. the Benchmark)
The gap between the ideal and reality is large. According to Vanguard's recensus of millions of accounts, the average 401(k) balances by age look roughly like this:
- Under 25: ~$5,000–$7,000
- 25–34: ~$30,000–$37,000
- 35–44: ~$75,000–$91,000
- 45–54: ~$160,000–$170,000
- 55–64: ~$235,000–$245,000
But here's the crucial detail almost everyone misses: the average is wildly misleading. A handful of very large accounts pull the average up. The median — the balance of the person right in the middle — is far lower, often less than half the average. For the 55–64 group, the median is frequently around $85,000– $90,000, not $240,000. If you feel behind compared to the "average," remember you're being compared to a number skewed by high earners.
Why Starting Early Beats Saving More Later
The reason these benchmarks front-load so heavily — 1× salary by 30 — is compound growth. Consider two savers, both targeting retirement at 65, both earning a 7% average annual return:
- Early Erin invests $6,000/year from age 25 to 35 (10 years, $60,000 total), then stops contributing entirely and lets it grow.
- Late Liam invests nothing until 35, then contributes $6,000/year from 35 to 65 (30 years, $180,000 total).
At 65, Erin has roughly $640,000 from her $60,000 of contributions. Liam has roughly $610,000 from his $180,000. Erin contributed one-third as much and still came out ahead, purely because her money had more time to compound. Time, not the contribution amount, is the dominant variable.
2025 Contribution Limits (Use Them)
The IRS caps how much you can contribute each year. For 2025:
- Employee contribution limit: $23,500
- Catch-up contribution (age 50+): an extra $7,500
- Enhanced catch-up (ages 60–63): a higher amount under SECURE 2.0
Employer matching contributions sit on top of your personal limit. If you're not contributing enough to capture your full employer match, fix that before anything else — it's the only guaranteed 50%–100% instant return you'll ever find.
Run your own numbers: enter your salary, contribution rate, employer match, and years to retirement to see your projected balance.

- Capture the full match first. Free money beats every other move.
- Increase your contribution rate by 1% a year. It's small enough that you won't feel it in your paycheck, but it compounds. Many plans automate this.
- Bank your raises. When your income rises, push part of the increase straight into your 401(k) before lifestyle creep absorbs it.
- Don't cash out when changing jobs. Roll old 401(k)s into an IRA or your new plan. Cashing out triggers taxes, a 10% penalty, and resets your compounding.
The Bottom Line
The benchmarks — 1× by 30, 3× by 40, 6× by 50 — are a useful compass, not a scoreboard. If you're behind, the most powerful lever isn't finding a magic investment; it's raising your savings rate and giving your money more time. The best day to start was a decade ago. The second-best day is today.
