What is FIRE?
FIRE stands for Financial Independence, Retire Early. It is a lifestyle movement focused on aggressive saving and investing to build a portfolio large enough to sustain your living expenses indefinitely, allowing you to retire much earlier than the traditional age of 60-65.
The core idea is to save a large percentage of your income (typically 50-70%) and invest it wisely so that your investment returns can cover your expenses. Use our Retirement Calculator for traditional retirement planning.
Types of FIRE
- Lean FIRE: Achieves FI with a minimalist lifestyle and lower expenses. Typically targets 25x of a bare-bones budget.
- Fat FIRE: Targets a higher portfolio to maintain a comfortable or luxurious lifestyle after retirement.
- Barista FIRE: Semi-retirement where part-time or freelance income covers some expenses while your portfolio covers the rest.
- Coast FIRE: Saving enough early that compound growth alone will reach full FI by traditional retirement age, without further contributions.
FIRE Number Formula
FIRE Number = Annual Expenses × (100 / Withdrawal Rate)
Using the 4% rule:
FIRE Number = Annual Expenses × 25
Where:
- Annual Expenses = Your yearly living costs (inflation-adjusted at FIRE)
- Withdrawal Rate = Safe annual withdrawal percentage (typically 3-4%)
- 25 = Multiplier derived from the 4% rule (100 / 4 = 25)
Key Factors Affecting FIRE
- Savings Rate: The single most important factor. A higher savings rate dramatically reduces years to FIRE.
- Investment Returns: Higher returns accelerate portfolio growth. A diversified portfolio of stocks and bonds is common.
- Inflation: Erodes purchasing power over time. Your FIRE number must account for inflation-adjusted expenses.
- Withdrawal Rate: A lower rate (3%) is safer but requires a larger corpus. The 4% rule is widely used but may need adjustment.
- Income Growth: Rising income with controlled expenses accelerates savings.
