401(k) Match vs Salary Calculator
See how much free employer-match money you're capturing — or leaving on the table — and what it's worth years from now.
Your 401(k) Match Breakdown
Your Contribution
$2,400
Employer Match
$1,200
Total This Year
$3,600
You're leaving $1,200/year of employer match on the table.
Contributing at least 6% instead of 3% would capture the full match, worth an extra $147,584 after 20 years at a 7% return.
What Is the 401(k) Match vs Salary Calculator?
An employer 401(k) match is money your employer contributes to your retirement account on top of your salary, based on how much you personally contribute — most plans match a percentage of every dollar you put in, up to a cap expressed as a percentage of your salary. This calculator shows exactly how much of that match you're capturing at your current contribution rate, how much you're leaving unclaimed if you're contributing below the cap, and what that gap is actually worth by the time you retire, not just this year.
The "leaving money on the table" framing matters because an unmatched employer contribution is effectively free compensation tied to a specific action (contributing at least up to the cap) — unlike salary, you can't get it back later by contributing more next year. If your plan matches 50% up to 6% and you only contribute 3%, you permanently forfeit that year's unmatched portion the moment the plan year closes.
For the full picture of what a 401(k) contribution costs you in take-home pay, see the Take-Home Pay After Benefits Calculator, and for the traditional-vs-Roth decision once you know your contribution amount, a 401(k) vs Roth IRA comparison is planned for this category as well.
401(k) Match vs Salary Calculator Formula
Employer Match = Salary × min(Your %, Match Cap %) × Match Rate %
Money Left on Table = (Salary × Match Cap % × Match Rate %) − Employer Match
Future Value = Annual Total × [((1 + r)^n − 1) / r]
How Is the 401(k) Match vs Salary Calculator Calculated?
The employer match only applies up to the plan's cap — contributing more than the cap doesn't get you more match, it just means more of your own money is going in unmatched (which can still be worthwhile for the tax-advantaged growth, just not for "free money" purposes). The future value figure uses the standard future-value-of-an- ordinary-annuity formula, treating your combined annual contribution as a level amount invested once a year and compounded at your expected return — real contributions are usually per-paycheck rather than once a year, which in reality compounds slightly faster than this simplified annual model shows.
Your own contribution is capped at the 2026 IRS elective deferral limit ($24,500, or $32,500 if you're 50 or older) regardless of what percentage you enter, since that's the legal maximum a plan can accept from you in traditional or Roth 401(k) elective deferrals combined.
401(k) Match vs Salary Calculator Example
A $80,000 salary with a plan that matches 50% up to 6%: contributing only 3% gets you $2,400 of your own money plus $1,200 in match — but leaves $1,200/year of match unclaimed. Over 20 years at a 7% return, capturing the full 6% instead of just 3% is worth an extra $147,584, since the total going in every year doubles from $3,600 to $7,200.
A $60,000 salary with a dollar-for-dollar match up to 3% (100% match rate, 3% cap): contributing exactly 3% gets $1,800 from you and $1,800 in match — the full match, with nothing left on the table, growing to roughly $340,059 over 30 years at 7%.
A high earner on $500,000 contributing 10% (which would be $50,000) hits the 2026 IRS limit of $24,500 well before reaching that percentage — the calculator caps the contribution at the legal limit and computes match based on the requested rate.

Understanding Your Result
"Money left on the table" is the employer match you're not receiving because your contribution rate is below your plan's match cap — it's not a tax or penalty, it's simply match your employer would pay if you contributed more, that goes unclaimed at your current rate. The projected future value shows what capturing (or not capturing) that match is worth by the end of your chosen time horizon, assuming steady contributions and a constant annual return.
If the result shows you're already capturing your full match, contributing further beyond the cap is still tax-advantaged retirement saving — it just isn't matched by your employer, so it doesn't carry the same "instant return" the matched portion does.
Tips
- If you can't afford to contribute up to the full match cap right now, prioritize getting there before increasing contributions elsewhere — it's typically the highest guaranteed return available.
- Check whether your plan matches based on a per-paycheck rate or a full-year true-up — some plans stop matching once you hit the IRS limit early in the year, causing you to miss match in later paychecks.
- A higher match rate with a lower cap can be worth less in total dollars than a lower match rate with a higher cap — compare the dollar amount, not just the headline percentage.
- Re-run this after every raise, since your match cap in dollar terms grows with your salary even if your contribution percentage stays the same.
- This tool assumes annual compounding as a simplification — actual per-paycheck investing compounds slightly more, so real results tend to be marginally higher than shown.
Common Mistakes
- Contributing less than the match cap and not realizing the unmatched portion is gone for good once the plan year ends.
- Assuming a higher match percentage is always better without checking the cap it applies to.
- Forgetting that your own contribution is capped by the IRS limit regardless of the percentage you set.
- Not accounting for a plan's lack of true-up provisions, which can cause high earners to miss match by front-loading contributions early in the year.
- Comparing only this year's match dollars and ignoring the compounding effect over a full career.
Frequently Asked Questions
What does 'match cap' mean?
It's the maximum contribution percentage your employer will match, expressed as a percentage of your salary. A plan that matches '50% up to 6%' pays 50 cents for every dollar you contribute, but only on the first 6% of your salary you contribute — anything beyond 6% isn't matched.
Is employer match counted toward the IRS contribution limit?
No — the 2026 employee elective deferral limit ($24,500, or $32,500 with catch-up) applies only to what you personally contribute. Employer match doesn't count against that limit, though it does count toward a separate, much higher combined limit ($72,000 for 2026) under IRC Section 415(c).
What if I can't afford to contribute up to the match cap?
Contribute what you can — even partial capture of the match is better than none. This calculator is meant to show the size of the gap so you can prioritize increasing your rate when your budget allows, such as after a raise.
Does this calculator account for vesting schedules?
No — some employers require you to work a certain number of years before employer match contributions are fully yours (vesting). This calculator assumes the match is fully vested; check your plan documents for your specific vesting schedule.
What return rate should I use for the projection?
There's no guaranteed rate — 7% is a commonly used long-term estimate for a diversified stock-heavy portfolio after inflation, but actual returns vary significantly year to year and depend entirely on your investment choices within the plan.
Why is my own contribution capped in the results?
The IRS sets an annual maximum on employee elective deferrals across all 401(k)/403(b)/governmental 457 plans combined — $24,500 for 2026 ($32,500 if you're 50 or older). Entering a percentage that would exceed this at your salary gets capped at the legal limit.
Does a Roth 401(k) match work the same way?
The matching mechanics are the same, but employer match contributions are always made on a pre-tax (traditional) basis, even if your own contributions are Roth — this calculator models the match dollar amount, which is the same regardless of which type you contribute to.
Is 'free money' from a match actually free?
It's not taxed as income when contributed, and it's yours (once vested) without you having done anything except contribute your own portion — it's about as close to free compensation as exists in a typical pay package, which is why maximizing it is common financial advice.
What's the difference between this and a total compensation calculator?
This tool focuses specifically on the 401(k) match trade-off. A broader Job Offer Total Compensation comparison, covering salary, bonus, equity, and benefits together, is planned for this category as a separate tool.
Can I model an increasing match tier, like 100% on the first 3% and 50% on the next 2%?
Not directly — this calculator uses a single match rate and cap. For a tiered match, run it once per tier and add the results together, or use the average effective match rate across your total contribution.
Does changing jobs reset my contribution limit?
No — the IRS elective deferral limit applies per calendar year across all employers combined, not per employer. If you contribute the max at one job and then switch employers mid-year, you need to track your year-to-date total to avoid over-contributing.
Can I share my match breakdown as an image?
Yes — tap Share and, on supported devices, your result is shared as a branded image card, not just a text link.
