What does this calculator estimate?
A 401(k) employer match is free money your employer adds to your retirement account, typically matching your contribution up to a percentage of your salary. This calculator estimates the match and its value. Enter your salary, contribution, and match terms see it.
- Employer match is a guaranteed return
- Match = salary × contribution % up to the limit
- Contribute at least enough to get the full match
How a 401(k) match works
An employer match adds money to your 401(k) when you contribute — commonly 50% or 100% of your contribution up to a cap (e.g. 6% of salary). It's essentially free money and usually the best return you'll get, because the match is immediate.
Limitations to watch for
The match is capped — contributing more than the match limit doesn't increase the match. Vesting schedules mean unvested match money may be forfeited if you leave early. The match is tied to your salary and pay periods, and you must contribute enough to earn it.
How to use it in practice
Contribute at least enough to capture the full match — anything less leaves free money on the table. Because the match is a guaranteed return, max it before investing elsewhere. Factor in vesting and your tax situation as part of the overall retirement plan.
- Enter your annual salary.
- Enter your contribution % and the employer match % and limit.
- The calculator estimates the annual match value.
How the match formula works
The most common match is dollar-for-dollar on the first 3 percent of salary, then 50 cents on the next 2 percent — a '3% dollar-for-dollar, 2% half' structure. On a $60,000 salary, that adds up to 3% of $60,000 = $1,800 at full match, plus 1% of $60,000 = $600 at half match — $2,400 total, or 4 percent of salary.
The free-money threshold
The match is employer money you forfeit by contributing less than the full match threshold. Contributing 3 percent to a plan with a 3 percent dollar-for-dollar match leaves the other 3 percent unclaimed — an immediate 100 percent return that no investment can beat. The calculator shows the forfeited amount so the decision is visible.
Vesting changes the eventual value
Unmatched contributions are yours immediately; the match may vest over a schedule (for example, 20 percent per year over five years). If you leave before vesting, the unvested match is forfeited. The calculator shows the gross match; check your plan's vesting schedule to know what you actually keep.
Match cap and contribution limits
The match is capped at a percentage of salary, and total contributions (yours plus employer) are subject to annual IRS limits. High earners can hit the cap before year-end; the calculator models the match on your salary and chosen contribution so the cap effect is visible.
A worked example
On a $50,000 salary with a 4% dollar-for-dollar match, contributing 4% adds $2,000 from you and $2,000 from the employer each year. At a 7% return over 30 years, that extra $2,000 annually grows to more than $200,000 — the match is the largest guaranteed return most employees can get.
How this calculator works
Formula
Employer match = salary × employee contribution % matched up to the employer's limit, applied per pay period. The calculator computes how much your match is worth and how it accumulates with your own contribution.
Worked example
A $60,000 salary, 6% employee contribution, 100% employer match up to 6% limit: the employer adds $3,600/year, effectively doubling your contribution up to that limit.
Assumptions to verify
- Match is a percentage of salary, capped at the employer's limit.
- The employee contribution qualifies for the match only up to the stated cap.
- Pay periods are annualized for the estimate.
Frequently asked questions
What is the 401(k) employer match?
An employer contribution matching yours, typically up to a percentage of your salary (e.g. 100% of up to 6%). It's free money on top of your own contribution.
How much should I contribute?
At least enough to capture the full match — that's an immediate guaranteed return. Most advisors recommend matching, then maximizing other tax-advantaged accounts.
What does 'matching up to 6%' mean?
The employer matches your contribution (often dollar-for-dollar) until it reaches 6% of your salary. Above that, the employer match stops.
Is the match subject to vesting?
Sometimes. Vesting schedules mean unvested matched money may be forfeited if you leave before a set period. Your own contributions are always yours.
How is the match calculated?
Match = your salary × your contribution % × the employer match %, capped at the employer's limit (e.g. 6% of salary).
What is the 2025 401(k) limit?
The employee contribution limit is $23,500, plus a $7,500 catch-up for those 50+. Employer matches don't count toward your limit. Confirm the current year's figure.
Should I choose traditional or Roth 401(k)?
It depends on whether you expect higher taxes now or later. Traditional gives a tax deduction now; Roth gives tax-free withdrawals later. Many use both.
What is a typical 401(k) employer match?
Common structures are dollar-for-dollar on the first 3–6% of salary, sometimes with a half-match on the next tier.
How much should I contribute to get the full match?
At least the full match threshold — anything less forfeits free employer money.
What does vesting mean?
Vesting is when the match becomes yours; leaving before fully vested forfeits the unvested portion.
Is the match part of the contribution limit?
Employee and employer contributions together count toward the annual IRS limit, though the employer portion has its own rules.
