Maximum 401k Contribution Limit 2025. For 2025, the 401(k) limit for employee salary deferrals is $23,000, which is above the 2023 401(k) limit of $22,500. The 2025 contribution limits for 401 (k), 403 (b), and most 457 plans have been raised, increasing by $500 the amount plan participants can contribute.

Employer matches don’t count toward this limit and can be quite generous. In 2025, the contribution limit for a roth 401 (k) is $23,000, plus an additional contribution of $7,500 if you are age 50 or older.
