💡 Key 401(k) Strategies

  • Always get the full employer match — it's free money (100% return)
  • Traditional vs Roth 401k: Traditional = tax deduction now; Roth = tax-free in retirement
  • Increase contribution by 1% per year — you won't notice the difference
  • Don't cash out when changing jobs — roll over to IRA or new employer's plan
