  • Required distributions: Must start at 73

Roth (After-Tax)

  3. Build emergency fund: 3-6 months expenses
  4. Max out Roth IRA: $7,000/year (if eligible)
  5. Max out 401(k): $23,500/year
  6. Consider HSA: If you have HDHP
  7. Taxable brokerage: After maxing tax-advantaged accounts

Common Retirement Mistakes

  1. Not starting early enough: Compound interest is powerful
  2. Missing employer match: Leaving free money on table
  3. Cashing out when changing jobs: Penalties + taxes
  4. Too conservative too young: Missing growth
  5. Not increasing contributions: With raises
  6. Ignoring fees: 1% fee = $100K+ lost over career
  7. Taking 401(k) loans: Derails compound growth

Social Security Tips

Healthcare in Retirement

Plan for Healthcare Costs

  • Average couple needs: $315,000 for healthcare in retirement
  • Medicare starts at 65: But doesn't cover everything
  • Gap coverage: Medigap or Medicare Advantage
  • HSA: Great for healthcare in retirement (triple tax advantage)
