Use this 401k max contribution calculator to check deferral room against IRS limits. Enter your age, planned employee contributions, and employer match to see remaining room, catch-up eligibility, and whether you are within IRS annual addition limits. For balance projections, use the 401(k) Calculator.
Enter your age, annual compensation, planned annual employee contribution, employer match % (match rate), and match up to % of salary. Calculate to see deferral limits, employer match dollars, total additions, and whether you are within IRS caps. Planned contributions can be entered as dollars or a percent of compensation.
Example: age 40, $100,000 compensation, $20,000 employee deferral, 50% match up to 6% of salary → $3,000 employer match and $23,000 total additions, within both the deferral and total additions limits.
Checks your planned 401(k) contributions against 2026 IRS limits: $24,500 elective deferral, $8,000 catch-up for age 50+, and $72,000 total annual additions including employer match. Employer match is salary-based: matched % = min(your deferral % of compensation, match-up-to %); employer dollars = compensation × matched % × match rate. Shows remaining room and any amount over the limits.
