401(k) Contribution Limits for 2026: How to Max Out the New $24,500 Cap

What's changing in 2026

Starting this year, the IRS employee contribution limit for 401(k), 403(b), and most 457 plans climbs to $24,500, up from the prior year's cap. It's a modest but meaningful bump, and if your paycheck deferral percentage hasn't changed, you're probably not on track to use the new room automatically. Employer matching and profit-sharing contributions sit on top of this limit under a separate combined cap, so the $24,500 figure is about what you personally choose to defer from your paycheck.

Who benefits most from the higher cap

High earners and disciplined savers in their peak income years get the clearest benefit, since they're the ones most likely to already be bumping against the old ceiling. But even if you're nowhere near maxing out, the new limit is worth noting because it resets the ceiling on tax-deferred growth and, for Roth 401(k) savers, tax-free growth. If you got a raise this year, redirecting even half of it toward your 401(k) is a painless way to inch closer to the cap.

Catch-up contributions after 50

If you're 50 or older, you can still stack an additional catch-up contribution on top of the $24,500 base limit, meaningfully raising your personal total for the year. Savers aged 60 to 63 get an even higher catch-up amount under the SECURE 2.0 rules, so double-check your plan's contribution settings if you fall in that window, since many payroll systems don't apply the enhanced catch-up automatically.

A simple plan to actually reach $24,500

Divide $24,500 by your number of remaining pay periods this year to see the per-paycheck deferral you'd need starting now, then compare that to your current contribution. If the gap feels too large to close all at once, raise your deferral percentage by 1-2% each quarter, or route your next raise and any bonus directly into your 401(k) before it hits your checking account. The goal isn't perfection in month one, it's a contribution rate that trends toward the cap by year-end.

Model it before you commit

Because the new limit changes your available tax-deferred space, it's worth re-running your numbers rather than guessing. The Retirement Planning Workbook lets you plug in your current contribution rate, age, and target retirement date to see exactly how much closer the $24,500 cap gets you to your personal retirement number, and what a modest increase in your deferral rate does to your projected balance over the next 10, 20, or 30 years.
