How does a 50% match up to 6% actually work?

Your employer adds 50 cents per dollar you contribute, but only on contributions up to 6% of your salary. Contribute 6% of $80,000 ($400 a month) and the match is 3% of salary ($200 a month); contribute 10% and the match still caps at $200.

Should I contribute more than the match limit?

The match limit is the no-brainer threshold because of the instant 50–100% return on matched dollars. Beyond it, the right amount depends on your goals, other accounts, and tax situation — model it here, decide with a professional if unsure.

Retirement Calculator — 401(k) with Match

The workplace-plan view. Instead of a flat monthly deposit, you enter your salary, the percent you contribute, and your employer's match formula — for example 50% of contributions up to 6% of salary — and the projection adds the match on top. On an $80,000 salary contributing 6% with that match, you put in $400 a month, the employer adds $200, and the page flags when contributing below the match limit leaves free money on the table.

A compounding projection from the ages, amounts, and return you assume — real returns vary year to year and are not guaranteed. This is an estimate for planning, not financial advice; taxes and fees are not modeled.

The match is an instant return

An employer match is the only place in retirement saving where a dollar becomes a dollar-fifty the moment it is deposited. With $50,000 already saved at 35, a $400 employee contribution alone projects to about $1,015,810 at 65 (at an assumed 7%); add a $200 monthly match and the same saver projects to roughly $1,137,807 — the employer's $72,000 of deposits turns into about $122,000 of extra balance through compounding.

That is why the standard ordering is: contribute at least up to the match limit before anything else. The calculator's "match left on the table" flag fires whenever your contribution percentage is below the limit your employer will match.

What the 401(k) view simplifies

Real plans add details this projection skips: annual IRS contribution limits, vesting schedules that claw back unvested match if you leave early, salary growth, and true-up policies. The math here treats salary and percentages as constant, which is the right first approximation but worth adjusting as your situation changes.
