FIRE Planning for Military Family

Military Family households face a 1.6x cost multiplier compared to a single person. The FIRE number for a Military Family family is approximately $19,200,000 assuming monthly expenses of $64,000 and a 4% safe withdrawal rate. This assumes baseline expenses and may not account for special circumstances (medical, education, etc.).

Specific Considerations for Military Family

  • Survivor benefits: Ensure both spouses have adequate life insurance (10-12x income) and that retirement accounts have proper beneficiary designations.
  • Social Security spousal benefits: The lower-earning spouse can claim up to 50% of the higher earner's benefit. This often makes delaying Social Security more valuable for couples.
  • Healthcare for both: Double the insurance costs, double the long-term care planning needed. Long-term care insurance or self-insurance via a $300K+ sleeve is worth modeling.

Recommended Strategy

For Military Family 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
