The 401(k) match you're leaving on the table

It's the closest thing to free money your job offers — a guaranteed 100% return — and about one in five workers walks past part of it every paycheck.

There is no investment on earth that reliably returns 100% the instant you make it — except an employer match. Put in a dollar, your employer drops in a dollar (up to a limit), before the market does anything at all. And yet a sizeable share of workers leave part of it sitting there, usually because no one ever spelled out the math.

The match, in plain numbers

Take that typical “100% of 3% + 50% of 2%” formula on a $60,000 salary. Contribute 5% and the free money lands on top of your own savings — no strings, no waiting.

Contribute 5%, get 4% free — on a $60k salary

Why a “small” 4% is enormous over time

That $2,400 a year isn’t just $2,400. Invested and compounding over a career, the match you skip becomes a six-figure hole in your retirement.

Turning down the full match is the only “investment decision” guaranteed to lose money.

The fix, and the Canadian version

In the US: log into your 401(k) and raise your contribution to at least the percentage that earns the full match (often 5–6%). Find your exact formula in your plan summary or ask HR: “What do I need to contribute to get the full match?” If money’s tight, even getting to the match line first beats almost everything else.

In Canada: the same logic applies to a group RRSP or a Deferred Profit Sharing Plan (DPSP). If your employer matches contributions, contribute at least enough to capture the full match — it’s the same free 100% return.
