Specific Considerations for Couple with 1 Kid

  • Education funding: 529 plans can hold $300K+ per child for college. Factor $50-100K/year per child for private college, $25-30K/year for in-state public.
  • Healthcare costs are higher: Family ACA premiums run $1,200-2,500/month before subsidies. After 65, Medicare + family Medigap is significant.
  • Childcare vs. FIRE tradeoffs: Daycare ($15-25K/year per child) is the silent FIRE killer. Some families delay FIRE by 2-3 years to absorb this cost.

Recommended Strategy

For Couple with 1 Kid families, the path to FIRE typically requires:

  1. Maintaining a 40-60% savings rate for 15-20 years
  2. Maxing out tax-advantaged accounts (401k, IRA, HSA, 529 if applicable)
  3. Keeping housing costs under 25-30% of gross income
  4. Having 6-12 months emergency fund (more for families with dependents)
  5. Term life insurance (10-12x income) if dependents rely on your earnings
