2026 401(k) contribution limits
The IRS adjusts retirement plan contribution limits most years to keep pace with inflation. For 2026, the limits for 401(k), 403(b), and most 457 plans are:
| Limit | 2026 amount |
|---|---|
| Employee elective deferral limit | $24,500 |
| Catch-up contribution (age 50+) | +$8,000 |
| Total employee limit with catch-up | $32,500 |
| Combined employee + employer limit (under 50) | $72,000 |
| Combined employee + employer limit (50+) | $80,000 |
The "employee elective deferral limit" is the most relevant number for most people — it's the cap on what you personally can contribute from your paycheck in a year. The much higher "combined" limit includes your contribution plus whatever your employer adds through matching or profit-sharing, and only becomes relevant if you have an unusually generous employer match or are also making after-tax contributions.
How much should you actually contribute?
The IRS limit is a ceiling, not a target — very few people need or are able to max out a 401(k). A more useful way to think about your own contribution percentage is in this order:
- Get the full employer match first. If your employer matches, say, 100% of your contributions up to 4% of your salary, contributing at least 4% is an immediate 100% return on that portion — money left on the table if you contribute less.
- Build toward 10–15% of income (including any employer match) as a common long-term savings benchmark, adjusted for how early or late you're starting and when you want to retire.
- Increase gradually — many plans let you set an automatic annual increase (often 1% per year) so your contribution rises with raises rather than requiring a separate decision each year.
Why employer match changes the math so much
A dollar-for-dollar or 50%-match employer contribution is effectively a guaranteed, immediate return that no investment can reliably match — which is why "contribute at least enough to get the full match" is close to universal advice among financial planners, even for people focused on paying down debt or building an emergency fund first. Skipping the match to pay extra on a low-interest debt, for example, usually costs more in lost match than it saves in interest.
Beyond the match, the value of contributing more comes down to time horizon and expected investment growth — the earlier money goes in, the longer it has to compound. Our 401(k) Retirement Calculator lets you enter your salary, contribution percentage, employer match, and expected return to project your balance at retirement, so you can see the long-term effect of moving your contribution from, say, 6% to 10% rather than guessing.
What if you can't hit these numbers this year?
That's normal — the IRS limits describe the maximum allowed, not an expectation. If money is tight, prioritizing the full employer match and building a small emergency fund alongside even a modest 401(k) contribution (3–5%) is a reasonable starting point; you can use our Savings Goal Calculator to plan that emergency fund in parallel and increase your retirement contribution as your budget allows.
