401(k) Match Calculator
See exactly how much free money your employer's match is worth — including the three IRS Safe Harbor formulas — and whether you're leaving any of it on the table.

2026 compensation cap of $360,000 applied automatically for match calculation purposes. Match dollars almost always go into a Traditional (pre-tax) balance, even if your own contributions are Roth.
How to calculate employer 401(k) match
Two tiers cover almost every real-world formula, including all three Safe Harbor types.
Most match formulas — whatever your specific plan calls them — reduce to two tiers: a rate applied to your first few percent of contribution, and a second (usually lower) rate applied to the next few percent.
Match = (Tier 1 rate × Tier 1 contribution) + (Tier 2 rate × Tier 2 contribution)
Contribute below the plan's total cap and you're leaving free money on the table; contribute above it and the extra isn't matched at all, even though it's still your own money growing tax-advantaged.
How to calculate employer 401(k) match
A 401k match calculator, 401k matching calculator, matching 401k calculator, or 401k employer match calculator question usually starts with one of two common formulas: "50% up to 6%" (you get half of what you contribute, up to 6% of pay) or "100% up to 3%" (a full dollar-for-dollar match, up to 3% of pay). To calculate employer match 401k style, work out how to calculate employer 401k match, or figure out how to calculate 401k employer match for your specific plan, you just need your plan's tier rates and caps — exactly what the calculator above asks for.
Safe Harbor match formulas, exactly as the IRS defines them
A 401k safe harbor match calculator needs the precise formula, not an approximation — Safe Harbor plans exist specifically so employers can skip annual nondiscrimination testing, and the IRS defines exactly three qualifying match structures:
| Safe Harbor type | Formula | Max match |
|---|---|---|
| Basic (Classic) | 100% on first 3% + 50% on next 2% | 4% |
| Enhanced | Must equal/exceed Basic; common: 100% on first 4% | 4–6% |
| QACA (auto-enrollment) | 100% on first 1% + 50% on next 5% | 3.5% |
Worked example directly from Safe Harbor Basic guidance: an employee earning $50,000 who defers 4% gets a match of $1,750 (3.5% of pay); the same employee deferring 8% still caps out at the maximum $2,000 match (4% of pay), since contributions above the plan's cap simply aren't matched.
401(k) company match calculator: employer-by-employer variation
A 401k company match calculator, employer 401k match calculator, 401k calculator employer match, 401k contribution match calculator, or 401k contribution calculator employer match search reflects a real fact: unlike Safe Harbor formulas, a standard (non-Safe-Harbor) discretionary match can be whatever an employer chooses — different companies genuinely use different rates and caps, which is exactly why the calculator above lets you edit both tiers rather than assuming one universal formula.
Roth 401(k) contributions and the match
A roth 401k calculator with match search often assumes the match itself might be Roth — it isn't, in almost every plan. Regardless of whether your own contributions are Roth or Traditional, employer matching dollars are deposited into a Traditional (pre-tax) balance, and you'll owe ordinary income tax on that portion (and its growth) when you withdraw it. See our Roth or 401(k) Calculator for the full contribution-choice comparison.
Match vs. profit sharing
A 401k calculator with match and profit sharing search is really asking about two separate things. Matching is tied to what you personally contribute; profit sharing is a separate, fully discretionary employer contribution that doesn't depend on your own deferral at all, and can vary year to year based on company profitability. This calculator covers matching specifically — profit-sharing formulas vary too widely by employer to model with a single tool.
High earners and the compensation cap
The IRS caps how much compensation counts toward any 401(k) match formula — $360,000 for 2026. A 6%-of-pay match formula for someone earning $500,000 is still calculated on only the first $360,000, capping the employer's obligation regardless of the employee's actual salary. The calculator above applies this cap automatically.
Safe Harbor formulas and the 2026 compensation cap are verified against IRS.gov guidance on automatic contribution arrangements and current retirement plan limits. This is a planning estimate — your plan's official Summary Plan Description is the authoritative source for your specific formula.
Frequently asked questions
Before you set your contribution percentage.
What percentage should I contribute to get the full match?
Whatever your plan's total match cap is — the "Tier 2: up to this much of your pay" figure in the calculator above. Contributing less than that leaves free employer money unclaimed; contributing more doesn't earn additional match, though it can still be worth doing to reach your annual IRS contribution limit.
How do I calculate 401k employer match for my specific plan?
Check your Summary Plan Description for the exact tier rates and caps, then enter them into the calculator above — most formulas fit the same two-tier structure, whether it's a simple "50% up to 6%" or a full Safe Harbor design.
Is a Safe Harbor match better than a regular match?
Not necessarily bigger — Safe Harbor exists to let employers skip nondiscrimination testing, not to guarantee a more generous formula. Basic Safe Harbor tops out at 4%, actually lower than many discretionary "50% up to 6%" plans (3% max) or "100% up to 6%" plans (6% max).
Does the match count toward my personal IRS contribution limit?
No — the employee elective deferral limit ($24,500 for 2026) applies only to your own contributions. Employer match dollars are separate and count toward a much higher combined annual additions limit instead.
Is 401(k) match considered free money?
Effectively yes, as long as it eventually vests — some plans require a set number of years of service before employer contributions are fully yours if you leave. Check your plan's vesting schedule alongside the match formula itself.
