How Much Should I Contribute to My 401(k)?

Published July 9, 2026

"How much should I put in my 401(k)?" is one of the most-searched retirement questions — and for good reason. Contribute too little and you leave free money and decades of compound growth on the table; obsess over the maximum and you might strain your monthly budget. This guide gives you a clear, practical framework: the percentage to aim for, how to capture every dollar of your employer match, the 2026 contribution limits, and how your balance compares by age.

The Short Answer: Aim for 15%

Most financial planners recommend saving 15% of your gross (pre-tax) income for retirement, including any employer match. If your employer matches 5%, you'd contribute 10% yourself to reach the 15% target. If there's no match, you'd contribute the full 15% on your own.

Can't hit 15% today? That's fine. The two rules that matter most are: (1) always contribute at least enough to get the full employer match, and (2) increase your contribution by 1% every year or whenever you get a raise. Small, automatic increases are nearly painless and add up enormously over time.

Rule #1: Never Miss the Employer Match

An employer match is the closest thing to free money you'll find in personal finance. A typical match is "100% of the first 3% and 50% of the next 2%," which fully rewards you for contributing 5% of your salary.

Consider someone earning $60,000 with that match:

  • You contribute 5% = $3,000
  • Employer adds 4% = $2,400
  • Total into your account: $5,400 per year

That $2,400 is an instant, guaranteed 80% return on your $3,000 — a return no stock or bond can promise. Failing to contribute at least 5% here means turning down a raise. Always capture the full match first, before considering any other investment.

2026 401(k) Contribution Limits

The IRS caps how much you can contribute from your own paycheck each year. For 2026:

Contribution Type2026 Limit
Employee contribution (under 50)$24,500
Catch-up contribution (age 50+)+$8,000
Total if age 50 or older$32,500

These limits apply only to your contributions — your employer's match is on top and does not count against them. Always confirm the current year's figures with the IRS, as limits are adjusted for inflation.

How Much 401(k) Should I Have by Age?

A widely used benchmark from Fidelity suggests saving a multiple of your salary at key ages. It's a useful gut-check, not a hard rule:

AgeSavings Target (× salary)Typical Average Balance
30~$30,000
40~$75,000
50~$170,000
60~$300,000
6710×~$430,000+

If you're behind these numbers, don't panic — medians are far lower than averages, and the catch-up contribution exists precisely to help those over 50 accelerate. The best time to start was yesterday; the second-best time is with your next paycheck.

Where 15% Isn't the Right Answer

The 15% rule is a starting point, not gospel. Adjust it when:

  • You have high-interest debt. Beyond capturing the match, paying off credit-card debt (often 20%+ APR) usually beats investing. Our Credit Card Payoff Calculator shows how fast you can clear it.
  • You have no emergency fund. Build a 3–6 month cushion alongside retirement saving. Size it with the Emergency Fund Calculator.
  • You started late. Someone beginning at 45 may need to save 20–25% to catch up. Model different rates in the Retirement Calculator.

Why Starting Early Beats Contributing More

Because of compound interest, time is more powerful than amount. A 25-year-old who invests $300/month until 65 (at a 7% average return) ends up with roughly $720,000. A 35-year-old who invests the same $300/month ends with about $340,000 — less than half, despite contributing for 30 of the 40 years. The extra decade of compounding does the heavy lifting.

Frequently Asked Questions

What percentage should I contribute to my 401(k)?

Aim for 15% of gross salary including the employer match. At minimum, contribute enough to capture the full match — usually 4–6% — because it's an immediate 100% return.

How much can I contribute to a 401(k) in 2026?

$24,500 if you're under 50, or $32,500 if you're 50 or older (with the $8,000 catch-up). Your employer's match is separate and doesn't count toward these limits.

What is the average 401(k) balance by age?

Roughly $30,000 in your 30s, $75,000 in your 40s, $170,000 in your 50s, and $300,000+ approaching retirement. Medians run lower — consistency matters more than any benchmark.

Is a 401(k) worth it?

For most people, absolutely — tax advantages, automatic investing, and free employer matching combine with decades of compounding to build real wealth.

Conclusion

Start by grabbing every dollar of your employer match, then work toward 15% by nudging your contribution up 1% a year. Let compounding and time do the rest. Model your own numbers with the 401(k) Calculator and the Retirement Calculator — a few minutes today can be worth six figures at retirement.
