An employer 401(k) match is the closest thing to free money in personal finance, yet a large share of workers leave part of it unclaimed by contributing less than the match threshold. This calculator shows exactly what your match is worth. Enter your salary, your contribution percentage, and your employer's match formula — most commonly '50% of contributions up to 6% of salary' or '100% up to 3%' — and it computes the dollars your employer adds each year, the instant return that represents on your own contributions, and what the match alone compounds into by retirement at your expected return. If you are contributing below the match limit, it also shows the annual amount you are leaving on the table, which is usually the single highest-return fix available in any financial plan: capturing a 50% match is an immediate 50% return before any market growth. The projection uses a steady salary and annual contributions for clarity; real outcomes will vary with raises, job changes, vesting schedules, and market returns, but the core message rarely changes — contribute at least enough to capture the full match before directing savings anywhere else.

How It Works

The match formula has two parts: the rate (how many cents your employer contributes per dollar you put in) and the limit (the maximum percentage of your salary they will match). Annual match = salary × min(your contribution %, match limit %) × match rate. Example: on an $80,000 salary with a 50%-up-to-6% formula, contributing 6% ($4,800) earns a $2,400 annual match; contributing 3% earns only $1,200, leaving $1,200 unclaimed every year. The instant-return figure is the match divided by your own contribution — a 50% match formula is an immediate 50% return on every matched dollar, which no ordinary investment reliably offers. The long-term projection treats the match as an end-of-year contribution compounding at your expected annual return: FV = match × [((1+r)^n − 1) ÷ r]. The projection holds salary constant for clarity — with raises, both your contributions and the match grow, so real outcomes are typically higher. Note that employer matches may be subject to a vesting schedule (commonly 3–6 years); unvested match dollars are forfeited if you leave early.

Examples

Standard formula: 50% up to 6% on $80,000
Contributing the full 6% with 30 years to retirement at a 7% return.
Result: $2,400 of free money per year — roughly $226,700 at retirement from the match alone.
Under-contributing: 3% on the same plan
Same salary and formula, but contributing only 3% of salary.
Result: $1,200/year captured — and $1,200/year left on the table, worth six figures over a career.
Dollar-for-dollar match: 100% up to 4% on $120,000
A generous full match at a higher salary, 25 years out.
Result: $4,800/year at a 100% instant return — about $303,600 by retirement from the match alone.

Frequently Asked Questions

What does '50% match up to 6%' actually mean?
It means your employer contributes 50 cents for every dollar you put in, but only on contributions up to 6% of your salary. On an $80,000 salary: if you contribute 6% ($4,800), the employer adds 50% of that ($2,400). If you contribute 10%, the employer still adds only $2,400 — the match stops at the 6% threshold. If you contribute 3%, you get just $1,200. The formula varies by employer; '100% up to 3%' and tiered formulas like '100% on the first 3%, 50% on the next 2%' are also common. Check your plan documents or ask HR for your exact formula.
Should I contribute more than the match limit?
Capturing the full match is the universally-agreed first step — it's an instant 50–100% return. Beyond the match, the answer depends on your situation: high-interest debt (credit cards at 20%+ APR) is usually worth eliminating before contributing beyond the match, while additional tax-advantaged saving (up to the annual IRS contribution limit) is excellent for most people once expensive debt is gone. A common ordering: full match → pay off high-interest debt → emergency fund → max IRA/401(k) → taxable investing.
What is vesting and how does it affect the match?
Vesting is the schedule on which employer contributions become permanently yours. Your own contributions are always 100% yours immediately. Match dollars may vest immediately, on a 'cliff' (e.g., 0% until 3 years, then 100%), or gradually (e.g., 20% per year over 5 years). If you leave before vesting, you forfeit the unvested portion. If you're planning a job change, checking your vesting date first can be worth thousands of dollars.
Does the match count toward my IRS contribution limit?
Not toward the employee limit. The IRS sets two caps: an employee deferral limit (your own contributions) and a higher combined limit covering employee plus employer contributions together. Employer match dollars consume only the combined limit, which most savers never reach. This means the match is additive — it never reduces how much you're allowed to contribute yourself.
Is the match taxed?
Traditional (pre-tax) match contributions are not taxed when made — they're taxed as ordinary income when withdrawn in retirement, like other traditional 401(k) dollars. Note that even if you make Roth 401(k) contributions, most employer matches are deposited as pre-tax dollars into a traditional sub-account (though newer rules allow some plans to offer Roth matching). Either way, the match is additional compensation that compounds for decades — the tax treatment changes when you pay tax, not whether the match is worth taking.
