How It Works

Employer 401(k) Match

A common match structure is 50% of your contributions up to 6% of salary.

Match = min(Your Contribution, Salary x Match Limit) x Match Rate

Common Match Formulas

| Formula | Example ($80k salary) | |---|---| | 50% up to 6% | $2,400/year | | 100% up to 3% | $2,400/year | | 100% up to 6% | $4,800/year |

Not contributing enough to get the full match is like leaving free money on the table.

Worked Example

$80,000 salary, contributing 6%, employer matches 50% up to 6%.

salary = 80000your_contribution_pct = 6match_rate = 50match_limit_pct = 6
  1. 01Your contribution = $80,000 x 6% = $4,800
  2. 02Matchable amount = min($4,800, $4,800) = $4,800
  3. 03Employer match = $4,800 x 50% = $2,400
  4. 04Total = $4,800 + $2,400 = $7,200/year
