401(k) Match Calculator United States
This 401k match calculator shows your 2026 employer 401(k) match in dollars and the extra match you miss by contributing below your plan's limit.
What it does
The 401(k) Match Calculator shows how much free money your employer adds to your retirement account each year and warns you if you are leaving part of that match unclaimed by not contributing enough of your salary.
Data sources & parameters
This calculator uses standard financial formulas and runs entirely in your browser. It needs no external rate data — your result is computed only from the values you enter above.
We always strive to use the latest data for every variable so our results and reports are as accurate as possible. Even so, errors are possible — you should not rely on this tool or its report alone, and we accept no liability for any decision made based on it.
The formula
Employer match = salary × min(your %, limit %) × match rate; missed match = salary × max(0, limit % − your %) × match rate
How it works
It multiplies your salary by the percentage you contribute, then applies your employer's match rate up to their match limit. If you contribute less than the limit, it also works out the extra match you could still capture.
Where it is used
- Checking you contribute enough to grab the full employer match
- Comparing job offers with different 401(k) match formulas
- Seeing the true dollar value of an employer match on your salary
Worked example
On a $60,000.00 salary, contributing 6% puts in … and earns a … employer match — … into your 401(k) that year, with … left on the table.
How the 401k match calculator works
Surveys regularly find that many employees do not contribute enough to claim their full employer 401(k) match. This 401(k) match calculator turns your plan’s match formula into dollars: what you put in, what your employer adds, the combined amount going into your account each year, and how much matching money you give up if you contribute below the limit.
A match has two parts, the match rate and the match limit. The rate is how much the employer contributes per dollar you defer, quoted as a percentage or in cents on the dollar, so a 50% match means 50 cents for every dollar you contribute. The limit caps the match at a percentage of your salary, most often 6%. Together, a 50% match up to 6% of pay is worth up to 3% of your salary in employer money, but only if you contribute the full 6% yourself. The calculator asks for your salary, your contribution percentage, the match rate and the match limit.
The two numbers answer different questions. The rate says how much each matched dollar earns, and the limit says how many of your dollars get matched. A dollar-for-dollar (100%) match capped at 3% gives the same 3% of salary as a 50% match capped at 6%, but the second plan requires you to save a larger share of your own pay to get it. Your plan’s summary description lists both figures.
Why contributing up to the limit matters
The most common mistake is contributing something, but not enough to reach the match limit. Every percentage point you defer below the limit earns matching dollars, and every point above it does not. If your limit is 6% and you contribute 3%, you receive half the available match. The calculator shows the gap as the match you are missing, in dollars.
No investment reliably returns an instant 50% or 100% on your money, and capturing the full match does exactly that: once the employer adds its share, you are up 50 cents or a dollar before the market moves. For most people, reaching the match limit should come before extra payments on low-rate debt and before taxable investing, because that return is guaranteed.
Reading the results
The calculator returns four numbers. Your contribution is your salary times the percentage you defer. The employer match applies the match rate to the smaller of your contribution rate and the plan limit, so it never overstates the benefit. Total going in per year adds the two, which is the amount invested for you. The match you are missing is the extra employer money you would get by raising your contribution to the limit. The donut chart splits the annual total into your money and your employer’s.
A worked example
Suppose you earn $60,000 and your plan offers a 50% match on the first 6% of pay. If you contribute 6%, you defer $3,600 and the employer adds $1,800, so $5,400 is invested that year and nothing is missed. If you contribute only 3%, you defer $1,800 and the employer adds $900, leaving another $900 of match unclaimed.
The lost growth is the larger cost. If that missed $900 a year were invested at a 7% average return, after 30 years the forfeited match alone would have grown to about $85,000, before counting any of your own contributions.
Common mistakes to avoid
Three traps come up often. One is front-loading contributions early in the year and hitting the IRS annual limit before December: if your plan has no true-up provision, the per-paycheck match stops for the remaining months even though you saved plenty overall. Another is treating the match limit as the savings goal. It is the minimum, and many planners suggest saving 10% to 15% of pay including the match. The third is ignoring vesting when you change jobs, because leaving a month before a vesting cliff can forfeit thousands in employer money. Check your schedule before you resign.
Assumptions and limitations
This calculator models one standard match formula: a single rate applied up to a single salary-based limit, on annual figures. It does not handle tiered or stretch matches (for example 100% on the first 3% plus 50% on the next 2%), non-elective or profit-sharing contributions, per-paycheck true-up rules, or the annual IRS contribution limits, which can cap high contributions. It also ignores vesting: the match shown is the gross amount added, not necessarily what you would keep if you left before being fully vested. Treat the output as a planning estimate and confirm the exact terms in your plan’s summary description.
