How Employer Matching Works

A common employer match is "50% up to 6%". This means if you contribute 6% of your salary, your employer adds another 3% (50% of 6%). Contributing more than the match limit usually doesn't get you extra free money from the employer.

Key Calculations

Annual Employee Contribution = Salary × Your Contribution %

Annual Employer Match = min(Your Contribution, Match Limit) × Match Rate

Future Value uses compound growth on current balance + growing contributions each year.

Important Notes

  • This calculator assumes tax-deferred growth (traditional 401k).
  • It does not account for investment fees, market volatility, or changes in contribution percentage over time.
  • Always try to contribute at least enough to get the full employer match — it's free money!
  • Consider Roth 401(k) options if you expect to be in a higher tax bracket in retirement.
