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
- 01Your contribution = $80,000 x 6% = $4,800
- 02Matchable amount = min($4,800, $4,800) = $4,800
- 03Employer match = $4,800 x 50% = $2,400
- 04Total = $4,800 + $2,400 = $7,200/year
