Money your employer adds to your 401(k) based on what you contribute.
An employer match is a contribution your company makes to your retirement plan, usually matching a percentage of your own contributions up to a cap. It is effectively an instant, guaranteed return on your savings — free money — so contributing at least enough to get the full match is almost always the highest-priority financial move.
A 50% match up to 6% of pay adds 3% of your salary if you contribute at least 6%.
