FIRE Formula
FIRE Number = Annual Expenses ÷ Withdrawal Rate
$50,000.00 ÷ 4% = $1,250,000.00
The 4% Rule
The 4% withdrawal rate is based on the Trinity Study, suggesting you can withdraw 4% of your portfolio annually with a high probability of not running out of money over 30 years. Adjust based on your risk tolerance and timeline.
Calculator Assumptions
- Withdrawal rate: 4% rule based on 30-year retirement; early retirees (40+ years) may need 3-3.5% for safety
- Returns: Default 7% is historical average after inflation; sequence of returns risk not modeled
- Expenses: Assumed constant in real terms; healthcare costs typically increase with age
- Inflation: Expenses shown in today's dollars; withdrawal rate accounts for inflation adjustments
- Taxes: Not included in expense calculations; budget 15-25% extra for taxes on withdrawals
- Social Security: Not included; will reduce required savings if you qualify
