The free money a '50% up to 6%' match adds on $60k
Two numbers, one formula
A common formula is '50% up to 6%'. It's easy to misread as a flat 6% match — on a $60,000 salary, that overestimates the match by $1,800.
The math: 6% × $60,000 = $3,600 (misread) vs 50% × $3,600 = $1,800 (real).

The first number: 50%
50% is the rate: for every dollar you contribute, your employer adds fifty cents on top — not a full dollar-for-dollar match.
The math: $1 you contribute means $0.50 match added by your employer.

The second number: 6%
6% is the most of your salary your employer will match. You can contribute more, but nothing past 6% of salary gets matched.
The math: 6% of a $60,000 salary is $3,600, the most that gets matched.

Putting both numbers together
On a $60,000 salary, contributing 6% ($3,600) gets you a 50% match worth $1,800 a year, added to your 401(k), not your paycheck.
The math: $3,600 contributed at a 50% match adds $1,800 a year from your employer.

Contribute less or more
Contribute 3% and the match is only $900. Contribute 10% and the match still caps at $1,800 — the extra 4% earns no additional match.
The math: 3% contribution gives $900 match; 10% still caps at $1,800.

Find your real numbers
Check your plan's summary plan description for your exact match rate and cap. Formulas vary, and some plans make you wait up to 6 years before the match is fully yours (vesting).
The math: A 100% match instead of 50% would double this example's $1,800 to $3,600.
