How this calculator works
You enter four numbers: the annual pay your plan counts toward the match, your contribution as a percentage of pay, the match rate and the share of pay the employer matches up to. A 50% match rate means 50 cents for each dollar you contribute, and “up to 6%” means only contributions up to 6% of pay are matched.
The calculator works on a yearly basis. It shows the employer match, any match left unclaimed, the total going into the account and the contribution rate that collects the full match. It stops your own contribution at the IRS 2026 limit of $24,500 and doesn’t add the extra catch-up amount allowed at age 50 and older.
The formula
Two numbers set the match. The limit caps which of your contributions are matched, and the rate decides how much each matched dollar earns. That’s why a 50% match on contributions up to 6% of pay adds at most 3% of pay, not 6%. Contributions above the limit still go into your account; they just aren’t matched.
A worked example
Imagine an illustrative plan that matches 100% of contributions up to 4% of pay, on $50,000 of eligible pay. Contributing 2% puts in $1,000 and collects a $1,000 match, leaving another $1,000 unclaimed. At 4%, your contribution and the match both reach $2,000. At 6%, you put in $3,000, but the match stays at $2,000 because the formula stops at 4%.
The table makes the pattern visible: the match climbs with your contribution until it reaches the formula’s limit, then stays flat. Contributing more than that can still add to your own retirement saving, but it doesn’t earn more match. Whether a contribution fits your budget is a separate question from what the formula pays.
| Your contribution rate | You contribute | Employer match | Match left unclaimed |
|---|---|---|---|
| 2% | $1,000 | $1,000 | $1,000 |
| 4% | $2,000 | $2,000 | $0 |
| 6% | $3,000 | $2,000 | $0 |
What the result doesn’t tell you
Employer contributions may vest over time. Your own contributions are always 100% yours, but leaving a job before the match is fully vested can mean keeping only part of it. Some plans also match each paycheck separately, so contributions bunched early in the year can miss match later on unless the plan makes a year-end “true-up.”
The calculator also leaves out investment growth, taxes, eligibility waiting periods, catch-up contributions and other IRS limits that can apply to high earners. Which pay counts toward the match, such as bonuses or overtime, is set by each plan. Your plan’s summary plan description covers the formula, the vesting schedule and those details.
Common questions
What does a 50% match up to 6% mean?
Your employer adds 50 cents for every dollar you contribute, on contributions up to 6% of your pay. Contributing 6% therefore earns a match worth 3% of pay. On $60,000 of eligible pay, that’s $3,600 from you and $1,800 from your employer each year. Contributing more than 6% doesn’t raise the match under this formula.
How much do I need to contribute to get the full match?
Usually the “matched up to” percentage in your plan’s formula, which the calculator shows as the contribution rate for the full match. If your plan matches each paycheck, you’d need to contribute at that rate in every pay period, not just on average over the year. At very high pay, the IRS contribution limit can be reached first, and the calculator accounts for that.
Is the employer match mine if I leave my job?
Your own contributions are always fully yours. The employer’s contributions depend on the plan’s vesting schedule: some plans vest immediately, while others vest gradually or all at once after a set period of service. Money that hasn’t vested when you leave can be forfeited. The vesting schedule is in your plan documents, including the summary plan description.
Does the employer match count toward the $24,500 limit?
No. The $24,500 limit for 2026 applies to your own elective contributions. Employer contributions count toward a separate, higher limit on total contributions to your account, generally $72,000 for 2026. If the plan allows catch-up contributions, people 50 and older can add up to $8,000 more, or up to $11,250 for those who turn 60 to 63 during the year. Starting in 2026, if your pay from that employer topped $150,000 the year before, those catch-up contributions have to be Roth (after-tax) contributions.
What if my plan’s match formula has two tiers?
Some plans match one rate on the first part of pay and a lower rate on the next part, for example dollar for dollar on the first 3% and 50 cents on the dollar for the next 2%. This calculator uses a single rate and limit, so you’d work out each tier separately and add them. Collecting everything means contributing up to the top of the last tier.
