The 10-Point Pre-Investment Checklist

  1. Emergency fund first: 3 months of expenses in HYSA before investing anything. This prevents forced withdrawals at bad times.
  2. High-interest debt paid: Any debt above 8% APR costs more than your expected investment return. Pay it first.
  3. Employer match captured: Confirm your 401(k) contribution captures 100% of available employer match.
  4. Correct account type: Roth IRA for tax-free growth; Traditional 401(k)/IRA for pre-tax; HSA if eligible. Get the account right before choosing funds.
  5. Expense ratio checked: Every fund in your portfolio should have an expense ratio below 0.20%. Index funds: 0.03–0.10%.
  6. Diversification confirmed: A single total market index fund provides adequate diversification. You don’t need more than 3–5 funds maximum.
  7. Auto-invest enabled: Confirm new deposits auto-invest rather than sitting in cash in the account.
  8. Beneficiaries designated: Retirement accounts with designated beneficiaries bypass probate. Name them now.
  9. Contribution limits checked: Know your annual limits (2025: $23,500 401k, $7,000 IRA) and confirm you won’t exceed them.
  10. 30-year projection run: Use the compound interest calculator to confirm your plan reaches your retirement goal. Adjust contributions if it doesn’t.

🔑The One Thing That Matters Most

All 10 checklist items matter — but starting is what matters most. A perfect investment setup started at 35 doesn’t beat an imperfect setup started at 25. Get the basics right (low fees, right account type, automated contributions) and begin. You can optimize later. You cannot recover lost compounding time.
