How the 401(k) raise calculator works
The pre-tax discount, explained
Traditional 401(k) dollars skip income tax on the way in. Electing $100 at a 22% marginal bracket costs $100 of gross but only $78 of lifestyle, because $22 of tax was never withheld. That discount is why a 3% election feels like a 2.3% pay cut — and why "I can't afford it" usually means "I am looking at gross, not net."
The match is the loudest money in finance
A 50% match is an instant 50% return; a 100% match doubles the money on deposit day. Nothing legal competes. The standard play: elect at least to the full match before any other goal — the 401(k)-raise calculator shows the match line so the decision is impossible to misread.
The 1%-a-year automation trick
Election increases of 1–2% a year (or auto-escalation if your plan offers it) outrun lifestyle perception: each step costs under $20 per paycheck for a median salary, and the compounding does the rest. The pain never arrives; the balance does.
