401(k) Employer Match Calculator
Your employer match is part of your pay — this shows you exactly what it's worth. Enter your salary, what you contribute, and your plan's match formula to see the match in dollars, whether you're leaving free money unclaimed, and what the match alone could grow to by retirement.
With the most common formula — 50% of your contribution up to 6% of salary — a $60,000 salary with a 6% contribution earns a $1,800/year match ($150/month, an effective 3% raise). Invested at 7% for 25 years, that match alone grows to about $113,800.
Enter your numbers
The defaults show the most common match ("50% up to 6%"). Your plan's formula is in your benefits summary or plan documents.
How to use it
- Enter your annual salary — gross pay, before taxes.
- Enter your contribution percentage — what you currently defer into the 401(k).
- Enter your plan's match formula — the two numbers in "matches X% up to Y% of salary." It's in your benefits summary; HR can tell you in one email.
- Optionally set years to retirement and a return to see what the match alone compounds into.
The headline is your annual match in dollars. If you're contributing below the match limit, the sub-line shows exactly how much free money you're passing up each year.
How an employer match works
A 401(k) match is extra pay that only exists if you claim it. Your employer commits to adding money to your 401(k) in proportion to what you contribute, up to a cap — most commonly "50% of your contribution, up to 6% of your salary."
Read that formula in two parts. The rate (50%) is how much they add per dollar you put in. The limit (6% of salary) is the most of your contribution they'll match. Contribute past the limit and the extra dollars still grow tax-advantaged — they just don't earn additional match.
That makes the match limit the single most important number in your plan: contributing at least up to it is an instant 50–100% return on those dollars, before any market growth. No other mainstream investment offers that.
Two fine-print items matter. Vesting: match money may become fully yours only after a few years of service — leave early and you forfeit the unvested part (your own contributions are always 100% yours). Per-paycheck timing: most plans match each paycheck, so front-loading contributions and hitting the annual IRS limit mid-year can accidentally reduce your match unless your plan has a "true-up" provision.
The formula & how we calculate it
Worked example (the defaults above):
- Salary $60,000, you contribute 6% ($3,600/yr), employer matches 50% up to 6%.
- Matched portion = min(6%, 6%) = 6% of $60,000 = $3,600.
- Annual match = $3,600 × 50% = $1,800/yr ($150/mo — an effective 3% of salary).
- Drop your contribution to 4% and the match falls to $1,200 — $600/yr left on the table.
- Invested at 7% for 25 years, the $1,800/yr match alone grows to about $113,848.
Common match formulas (on a $60,000 salary)
- 50% up to 6% — the classic. Full match = $1,800/yr; you must contribute 6% ($3,600) to get it.
- 100% up to 3% — dollar-for-dollar but lower cap. Full match = $1,800/yr at just a 3% contribution.
- 100% up to 4% — full match = $2,400/yr at a 4% contribution.
- Safe harbor (100% of first 3% + 50% of next 2%) — full match = $2,400/yr at a 5% contribution. For tiered formulas like this, run each tier through the calculator separately and add the results.
Whatever the formula, the rule of thumb is the same: contribute at least enough to collect the full match before putting savings anywhere else — see how the match changes your long-term balance in the full 401(k) calculator.
Frequently asked questions
How does a 401(k) employer match work?
Your employer contributes based on what you contribute, following a formula like "50% of your contribution, up to 6% of salary." On $60,000, contributing 6% ($3,600) earns a $1,800 match. Contribute less than the limit and the match shrinks proportionally; contribute more and it caps at the limit.
What is a typical employer match?
The most common formula is 50% up to 6% of salary — effectively an extra 3% of pay. The common safe-harbor design — 100% of your first 3% plus 50% of the next 2% — is worth up to 4% of salary ($2,400 on $60,000). Formulas vary a lot, so check your plan documents or ask HR.
Do I have to contribute to get the match?
Usually yes — a match only matches what you put in, so contributing 0% typically earns $0. Contributing at least to the match limit is widely considered the first rule of retirement saving: it's an instant 50–100% return before any market growth. (Some employers also make non-elective contributions that don't require you to contribute — that's a separate benefit.)
What does "leaving money on the table" mean?
Collecting less than the full available match. If your plan matches 50% up to 6% and you contribute only 4% of a $60,000 salary, you get $1,200 instead of $1,800 — $600 of compensation unclaimed every year. The calculator flags this automatically.
What is vesting?
The schedule that determines when match money becomes fully yours. Your own contributions are always 100% yours; employer contributions may vest gradually (e.g., 20% per year over 5 years) or all at once after a set period ("cliff" vesting). Leave before you're fully vested and you forfeit the unvested portion.
