How to read your employer match result
Two percentages that sound alike do completely different jobs. The match rate is cents per dollar you contribute; the match limit is how far up your salary that offer runs. The limit is what decides your maximum — at the defaults you're contributing 4% into a 6% offer, and the $800 gap is the whole point of the page.
How your 401(k) employer match is calculated
Two rules applied in order. Your employer matches a percentage of what you contribute — but only counts your contributions up to a ceiling expressed as a share of your salary. The ceiling bites first.
Which is why the maximum match is always match rate × match limit × salary, and never depends on what you actually contribute. At the defaults that's 50% × 6% × $80,000 = $2,400, whether you contribute 6% or 30%.
your contribution = contribution % × salary matched % = min(contribution %, match limit) employer match = matched % × salary × match rate max match = match limit × salary × match rate left on table = max match − employer match
- contribution %
- The share of your salary you defer into the plan — only the part below the match limit earns anything from your employer
- salary
- Your gross annual pay — both the match and the limit are percentages of this
- match rate
- Cents your employer adds per dollar you contribute — 50% is the most common; 100% ("dollar for dollar") exists on tighter limits
- match limit
- The share of salary your employer will match up to — the binding constraint — this sets your ceiling, not the match rate
- matched %
- The part of your contribution that actually earns a match — your rate or the limit, whichever is lower
- left on table
- Employer money you're eligible for but not collecting — goes to zero the moment your contribution reaches the match limit
One consequence of the formula is worth internalising: a headline match rate tells you almost nothing on its own. A 100% match up to 3% of salary and a 50% match up to 6% both max out at exactly 3% of pay — identical money, opposite-sounding offers. The generous-sounding one requires you to contribute half as much to collect it. Read the limit first, always. And note that everything here is annual: this calculator prices one year of match, while the 401(k) calculator compounds it to retirement.
Worked examples
Example: $80,000 salary, contributing 4% into a 50%-up-to-6% match
The calculator's defaults, and a common situation — you're contributing something, just not quite enough to reach the ceiling your employer set.
| Your contribution4% of $80,000 | $3,200 |
| Matched shareyour 4% is below the 6% limit, so all of it counts | 4% |
| Employer match4% × $80,000 × 50% | $1,600 |
| Maximum match available6% × $80,000 × 50% — i.e. 3% of pay | $2,400 |
| Left on the tableevery year you stay at 4% | $800 |
| Total into the 401(k)$3,200 yours + $1,600 theirs | $4,800 |
$800 a year of your own compensation, declined. Note what your 4% does earn: the full 50% on every dollar of it. Nothing is being wasted — you're simply stopping two percentage points short of where the offer stops.
Example: the same person moves to 6%
One slider, from 4% to 6% — exactly the match limit, and not a point further. Salary, match rate and limit all unchanged.
| Your contributionup $1,600 | $4,800 |
| Employer matchup $800 — now the maximum | $2,400 |
| Left on the tablefull match captured | $0 |
| Total into the 401(k)up $2,400 from $4,800 | $7,200 |
| Return on the extra $1,600instant, guaranteed, before any market return | 50% |
$1,600 more out of your pocket puts $2,400 more into the account. Push the slider past 6% and the match stays at $2,400 forever — at 20% you'd contribute $16,000 and still collect the same $2,400. The offer has a ceiling, and it's the limit, not the rate.
Frequently asked questions
What does a 50% match up to 6% mean?
Your employer puts in 50 cents for every dollar you contribute, counting only your contributions up to 6% of your salary. Contribute the full 6% and the employer adds 3% of your pay — half of 6%. That's the arithmetic the phrase hides: the match tops out at 3% of salary, not 6%.
On the $80,000 default, contributing 6% means $4,800 from you and $2,400 from them, $7,200 total. Contribute 4% and you get $1,600 instead of $2,400. Contribute 15% and you still get $2,400 — the limit caps what's matchable, and the rate only decides how much of that is matched.
What is the average 401(k) employer match?
Vanguard's plan data puts the average employer match around 4.6% of pay with a median of 4%, and roughly 98% of plans that offer a 401(k) offer some match. The single most common formula is exactly the calculator's default: 50 cents on the dollar on the first 6% of pay.
Tiered formulas are common too — a full match on the first 3% and 50% on the next 2%, for instance, which maxes out at 4% of pay for a 5% contribution. This calculator models the single-tier version only, so for a tiered plan enter the effective figures your summary plan description implies rather than the headline rate.
Does my employer's match count toward the 401(k) contribution limit?
Not toward yours. The $24,500 elective-deferral limit for 2026 (IRS Notice 2025-67) covers only what you defer from your own pay — your employer's match sits outside it entirely. You can max out at $24,500 and still receive every dollar of match on top.
There is a separate ceiling that covers both: the 415(c) limit, $72,000 for 2026, on everything going into the account from all sources in a year. It binds only where a large contribution meets a generous match or profit-sharing, and it's high enough that most savers never approach it. Neither this calculator nor the 401(k) projection applies it.
What is a 401(k) vesting schedule?
Vesting is when your employer's money actually becomes yours. Your own contributions are always 100% yours from day one — vesting applies only to the match. Until you're vested, that $2,400 a year is conditional on you still being there.
The IRS sets the outer bounds (Retirement Topics — Vesting): a plan can require up to three years of service before the match vests all at once ("cliff"), or vest it gradually over up to six years ("graded"). Some plans vest immediately. This calculator shows the match as though it were yours the moment it lands, which is true for the immediate-vesting plans and premature for the rest — check your summary plan description before counting it.
What this match calculator doesn't model
It prices a single year of one common match formula. Plans have more shapes than that, and the money has conditions attached.
- Vesting — The match is treated as yours immediately. Under a three-year cliff schedule, leaving at two years and eleven months forfeits every dollar of it. Graded schedules can run to six years.
- One tier only — Real formulas are often tiered — 100% on the first 3% then 50% on the next 2% is widespread. This model applies one rate up to one limit, so tiered plans need their effective equivalent entered instead.
- Per-paycheck true-up — The calculation is annual. Many plans match per pay period, so front-loading your contributions and hitting the deferral limit in October can forfeit the match on the pay periods you contributed nothing — unless your plan offers a true-up. This is a real and commonly-missed way to leave match money behind.
- No contribution limit applied — The calculator will let you contribute 20% of a $400,000 salary — $80,000 — without flagging that your deferrals are capped at $24,500 for 2026. It's pricing the match, not policing the plan.
- It's one year, uncompounded — The $800 left on the table is $800 this year. The reason it matters is what forty years of $800 becomes, and that question belongs to the 401(k) calculator, not this one.
