Never Leave Employer 401(k) Match on the Table
Of all the mistakes people make in retirement planning, failing to capture a full employer match is arguably the most avoidable — and the most expensive. Unlike market timing or fund selection, this one is entirely within your control the moment you set your contribution rate.
How Employer Match Works
Employer match is additional money your company contributes to your 401(k), tied to how much you personally contribute. A widely used formula is 50 cents per dollar you contribute, up to 6% of your salary — meaning if you contribute 6% of your salary, your employer adds another 3%. Formulas vary: some match dollar-for-dollar up to a smaller percentage, others match a smaller rate up to a higher cap.
Why It's Effectively Free Money
Employer match is compensation you've already earned the right to by taking the job — it just requires you to contribute your own share to unlock it. There's no equivalent in the open investment market for a guaranteed, immediate return on your contribution the moment it posts. Skipping it is like leaving a portion of your salary unclaimed.
The Long-Term Cost of Missing It
Because missed match compounds the same way regular contributions do, a small annual shortfall becomes large over a career. Missing $2,000/year in match for 20 years isn't just a $40,000 loss — it's the loss of everything that $40,000 would have compounded into, which at a 7% average return can be two to three times the original amount.
How to Make Sure You're Capturing It
Check your plan document or benefits portal for the exact match formula and the contribution rate needed to receive it in full. If you're contributing below that threshold, consider raising your contribution rate incrementally — many plans let you schedule automatic annual increases tied to raises, so the adjustment is barely noticeable in your paycheck.
Frequently Asked Questions
What is a typical employer match formula?
A common formula is 50 cents per dollar contributed, up to 6% of salary — meaning you need to contribute 6% of your own salary to receive the maximum match.
Is employer match considered free money?
Yes, in the sense that it's compensation you're entitled to that requires no market risk to receive — it's added the moment you contribute enough to qualify, functioning like an immediate guaranteed return.
Does employer match count toward the 401(k) contribution limit?
It doesn't count toward your personal elective deferral limit, but it does count toward the higher combined employee-plus-employer annual limit.
What if I can't afford to contribute enough for the full match?
Even a partial contribution captures partial match. Increasing your contribution rate gradually, such as with each raise, is a common way to work up to the full match threshold over time.
Does vesting affect whether I keep the match?
Some employers require a vesting schedule before you fully own matched contributions if you leave the company early. Check your plan's vesting schedule — your own contributions are always fully yours immediately.
