What a 401(k) match is actually worth in dollars
Most match explanations stop at the percentage. Percentages are not what lands in the account, so here is the same three formulas run against a $70,000 salary, which is close to the median for a small-employer plan.
| Match formula | What it means | You defer | Employer adds |
|---|---|---|---|
| 50% up to 6% | Half of every dollar you defer, capped at 6% of pay | $4,200 | $2,100 |
| 100% up to 3% | Dollar for dollar to 3% of pay | $2,100 | $2,100 |
| 100% of first 3% + 50% of next 2% (safe harbor basic) | Tiered; rewards deferring at least 5% | $3,500 | $2,800 |
Two of those formulas hand over the same $2,100 for wildly different contribution levels. That is why "we match 6%" tells an employee almost nothing on its own, and why the deferral rate needed to capture the full match is the number worth publishing in your enrollment materials.
The three ways employees quietly lose match money
1. Deferring below the match threshold
An employee deferring 3% into a 50%-up-to-6% formula collects $1,050 instead of $2,100. Nothing is broken, nothing gets flagged, and the money is simply never earned.
2. Front-loading without a true-up
Plans that match per pay period rather than annually will stop matching once an employee hits the deferral limit mid-year. If the plan document does not provide an annual true-up, the employee who maxed out in September permanently forfeits the match on the pay periods they sat out. Whether your plan trues up is a document question, not a payroll question — and plenty of sponsors do not know which one they signed.
3. Leaving before vesting
Deferrals are always 100% vested. The match usually is not. A six-year graded schedule means an employee who leaves at year three keeps 40% of the employer money and forfeits the rest.
What the match obligates the employer to do
This is the part that gets skipped. Promising a match creates operational duties that sit with the plan administrator, and failing them is one of the most common corrections we see:
- Fund on time. Deferrals must be deposited as soon as they can reasonably be segregated from general assets. Late deposits are a prohibited transaction, are reported on the Form 5500, and require lost-earnings restoration.
- Use the plan's definition of compensation. If the document says bonuses and commissions are included and payroll excludes them, every match calculation is wrong. This is the single most frequent operational failure in small plans.
- Pass the annual tests. A discretionary match must clear ACP testing. A safe harbor match buys an exemption — but only if the annual safe harbor notice went out on time.
- Track vesting and forfeitures. Forfeited match dollars must be used the way the document says, and unused forfeiture accounts sitting for years are now a live audit target.
Safe harbor match vs. discretionary match
| Safe harbor match | Discretionary match | |
|---|---|---|
| Annual testing | Exempt from ADP/ACP and usually top-heavy | Must pass ACP each year |
| Vesting | Immediate, 100% | Can be graded or cliff |
| Can you turn it off? | Only mid-year with notice and strict rules | Yes, year to year |
| Notice requirement | Annual notice, on a deadline | None |
| Best fit | Owner-heavy plans failing testing | Plans with strong rank-and-file participation |
The trade is flexibility for certainty. Sponsors who keep failing ADP testing and refunding money to owners almost always come out ahead with safe harbor, even though the match costs more.
Frequently asked
Does the employer match count against my contribution limit? Not against the employee deferral limit. It counts toward the much higher combined annual additions limit, which almost no small-plan participant reaches.
Can an employer stop a match mid-year? A discretionary match, generally yes going forward. A safe harbor match, only under specific conditions with advance notice to participants.
Is the match taxed? Traditional match dollars go in pre-tax and are taxed on withdrawal. Plans may allow the match to go to Roth, in which case it is taxable in the year contributed.
What if we discover our match was calculated wrong? It is correctable under the IRS EPCRS program, usually by making a corrective contribution plus earnings. Correcting it voluntarily is dramatically cheaper than having it found on audit.
