Employer match calculator
A match is the only guaranteed return in investing. This works out what yours is worth, and whether you are currently collecting all of it.
You put in / year
$2,100
Employer adds / year
$1,050
50% on top, before any growth
Match over 30 years
$99,184
You are contributing 3% but the match runs to 6%. Raising your contribution to 6% would add $1,050 of employer money a year — about $99,184 over 30 years, none of which comes out of your pocket.
Match formulas differ by employer and some have a vesting schedule, meaning the employer’s share only becomes yours after a set number of years. Your plan’s summary description has both — check it rather than assuming the defaults here match your plan.
Why a match is unlike any other return
Every other return in investing is uncertain. A match is not. If your employer adds fifty cents for every dollar you contribute, the moment the money lands you are up 50% on that portion — before the market has done anything, and regardless of what it does next.
No investment strategy reliably produces that. It is the one place where the return is contractual rather than hoped for, which is why “contribute at least enough to get the full match” is about as close to a consensus position as personal finance has.
How match formulas actually work
Two numbers define a match, and confusing them is the most common mistake:
- The match rate — how much the employer adds per dollar you contribute. A “50% match” is fifty cents per dollar.
- The cap — the share of your salary the match applies to. A match of 50% up to 6% of salary means the employer matches your contributions only until they reach 6% of your pay.
Contribute below the cap and you leave employer money unclaimed. Contribute above it and the extra is still worth saving — it just is not matched. The tool shows both cases.
The catch worth checking: vesting
Employer contributions often come with a vesting schedule — the money only becomes fully yours after a set period of service. Leave before then and some or all of the employer’s share goes back.
This does not change whether you should collect the match; it changes how you should think about the value if you expect to move jobs soon. Your plan’s summary description states the schedule.
What this calculator ignores
A steady return and a flat salary. Real salaries rise, which means real match amounts rise too — so a long projection here is likely conservative. It also ignores contribution limits, which cap what can go in each year, and taxes, which depend on whether the account is traditional or Roth.
Contribution limits change annually. Check the current figures at irs.gov, and confirm your own match formula and vesting schedule in your plan document rather than assuming the defaults here apply.
