401(k) Contribution Limits 2026 (And How Much You Should Actually Contribute)
The 2026 Numbers
- Employee elective deferral: $24,000 (up from $23,500 in 2025).
- Catch-up contribution (age 50+): $8,000, bringing the total to $32,000.
- Enhanced catch-up (ages 60–63, SECURE 2.0): $11,250 catch-up, total $35,250.
- Total combined limit (employee + employer): $71,000 (or $79,000 with age 50+ catch-up).
- Highly compensated employee threshold: $160,000.
These apply to traditional 401(k), Roth 401(k), and most 403(b) and 457(b) plans.
What "Contribution" Actually Means
Only your elective deferrals count against the $24,000. Employer match, profit-sharing, and after-tax contributions have their own bucket — that's why the combined ceiling is $71,000.
If your employer matches 4%, that match is on top of your $24,000, not part of it.
How Much You Should Actually Contribute
The max is $24,000. Most people shouldn't start there. Here's the order of operations:
Tier 1: Full employer match, always. If your employer matches 100% of the first 4%, contributing less than 4% is walking past free money. Nothing else in personal finance beats a 100% instant return.
Tier 2: Kill high-interest debt. Credit cards at 22% APR beat any 401(k) return. See pay off credit card debt fast.
Tier 3: Max a Roth IRA ($7,000). More investment choices, tax-free growth, easier withdrawals. Compare in Roth vs Traditional IRA.
Tier 4: Max HSA if eligible ($4,400 individual / $8,750 family). The HSA is the best retirement account most people ignore.
Tier 5: Back to 401(k), up to the $24,000 max.
Tier 6: Taxable brokerage. No limits, taxable dividends, full flexibility.
Traditional vs Roth 401(k)
- Traditional: tax break now, taxed on withdrawal. Better if you expect a lower tax bracket in retirement.
- Roth: no tax break now, tax-free in retirement. Better if you're early-career or expect higher future rates.
Under 40 and earning under $150k? Roth 401(k) is usually the right call. Split 50/50 if you can't decide — you'll thank yourself for tax diversification later.
What About Vesting?
Employer match is often on a vesting schedule (typically 3–6 years). If you leave before fully vested, you forfeit the unvested portion. Check your Summary Plan Description — this changes job-change math significantly.
The Real Contribution Target
Aim for a total savings rate of 15–25% of gross income across all retirement accounts. That's the number that gets most people to a normal retirement age. See how much you should have saved for retirement by age for the milestones.
Model It
Punch your 401(k) balance and monthly contribution into the compound interest calculator at a 7% real return. Then bump the contribution up $200/month and watch the retirement number jump six figures. That's usually all the motivation people need to raise their deferral before next payroll.
