Common Match Formulas

• Dollar-for-dollar up to 3%: $60K salary, contribute 3% ($1,800) → employer adds $1,800
• 50 cents per dollar up to 6%: Contribute 6% ($3,600) → employer adds $1,800
• 100% up to 4%: Contribute 4% ($2,400) → employer adds $2,400

1. Emergency starter fund ($1K)
2. Employer 401k match ← before other debt or investing
3. High-interest debt (>7%)
4. Full emergency fund
5. Additional retirement savings

Millions of Americans leave ~$1,300/year on table by not contributing enough to capture full match—described as “turning down free money” or “leaving a raise on the table.”
