What this match calculator solves
A 401(k) employer match cost calculator applies the plan formula to employee deferrals and shows annual employer expense as dollars and percent of salary.
Verify that employee deferrals and employer match stay within 402(g) and 415 limits.
See whether the match formula satisfies safe harbor requirements for nondiscrimination testing.
Key signals
Employer match cost, match as percentage of salary, employee deferral amount, and IRS limit status.
Decision support
Safe harbor compliance, formula comparison, and cost optimization opportunities.
Detailed breakdown
Tier-by-tier match calculation, IRS limit checks, and total contribution summary.
Calculate the match for single-tier formulas (e.g., 100% on first 6%) or two-tier formulas (e.g., 100% on first 3% plus 50% on next 2%).
Checks employee deferrals against the 402(g) limit and total contributions against the 415 annual addition limit automatically.
Evaluates whether the match formula meets IRS safe harbor requirements for basic or enhanced matching contributions.
Shows the employer match cost as both a dollar amount and a percentage of salary for budgeting and benchmarking.

How to use the 401(k) employer match cost calculator well
Key concepts, practical steps, and guidance for modeling match costs and checking IRS compliance.
A 401(k) employer match cost calculator applies the plan formula to employee deferrals and shows annual employer expense as dollars and percent of salary.
HR directors, CFOs, benefits administrators, and plan sponsors evaluating match formulas and costs.
Annual salary, employee deferral rate, match formula (standard or tiered), match percentage, and IRS contribution limits determine the employer match cost.
Workflow
Four practical steps
Use this calculator to model the employer match cost for any formula and verify IRS limit compliance.
1
Enter salary and deferral rate.Start with the employee annual compensation and their 401(k) deferral percentage. The deferral rate determines how much of the match formula the employee triggers.
2
Set the match formula and percentages.Choose standard (one tier) or tiered (two tiers). Enter the match percentage and the salary percentage it applies to for each tier.
3
Review the employer match cost.See the annual employer match in dollars, as a percentage of salary, and the total contribution (employee plus employer) for IRS limit checking.
4
Check IRS limit compliance.Verify the employee deferral is within the 402(g) limit and total contributions are within the 415 annual addition limit.
Review Checklist
What to validate first
Key details that affect match cost calculations and IRS compliance.
Use the plan definition of compensation (W-2 wages, 3401(a) wages, or 415 safe harbor compensation). Some plans exclude bonuses or overtime from the match calculation.
The match cost depends entirely on the employee deferral rate. Model multiple scenarios (3%, 5%, 8%) to see the cost range across typical participation levels.
Verify the exact match formula from the plan document. Small differences (e.g., 100% on 3% vs 50% on 6%) produce the same cost at full deferral but different costs at lower deferral rates.
Employee deferrals cannot exceed $23,500 for 2026 ($31,000 with catch-up for age 50+). If the deferral amount exceeds the limit, the match is calculated on the capped deferral.
Total annual additions (employee deferral plus employer match plus any other employer contributions) cannot exceed $70,000 for 2026 ($77,500 with catch-up).
The IRS basic safe harbor match is 100% on the first 3% plus 50% on the next 2%. Enhanced safe harbor is 100% on the first 4% or higher. Safe harbor plans skip ADP/ACP testing.
Why This Page Exists
Built to model 401(k) match cost before committing to a formula
Match formulas have real budget impact. This page lets plan sponsors model the cost for any formula and verify IRS compliance before adoption.
See the actual dollar cost of any match formula at any salary and deferral level instead of guessing at budget impact.
Verify 402(g) and 415 limits automatically so plan administrators catch issues before contributions are made.

FAQ
401(k) Employer Match Cost Calculator questions, answered directly
Short answers for searchers and answer engines.
The cost depends on the match formula, employee salary, and deferral rate. A common formula of 100% on the first 3% plus 50% on the next 2% costs the employer 4% of salary when the employee defers at least 5%. For an employee earning $95,000, that is $3,800 per year.
A tiered match uses two or more match rates applied to different portions of the employee deferral. For example, 100% match on the first 3% of salary deferred plus 50% match on the next 2%. This encourages higher deferral rates because the employee must contribute at least 5% to receive the full match.
The 402(g) limit caps employee deferrals at $23,500 for 2026 ($31,000 with the age 50+ catch-up). This applies to employee contributions only - employer match contributions are separate and do not count toward the 402(g) limit.
The 415 annual addition limit caps total contributions (employee deferrals plus employer match plus other employer contributions) at $70,000 for 2026 ($77,500 with catch-up). This is the combined ceiling for all contributions to the plan.
A safe harbor match lets the plan skip nondiscrimination testing (ADP/ACP tests). Common formulas: basic match (100% on first 3% plus 50% on next 2%), enhanced match (100% on first 4%), or a 3% non-elective contribution to all eligible employees. Safe harbor requires immediate vesting.
