Financial Independence, Retire Early (FIRE) Calculator

Calculate your path to financial freedom and early retirement

What is FIRE?

The FIRE (Financial Independence, Retire Early) movement is focused on intense saving and investing that allows people to retire much earlier than traditional retirement plans would allow. The core principle is simple: save and invest a large percentage of your income (often 50-70%) to accelerate your path to financial independence.

Financial independence is typically defined as having enough invested assets to cover your living expenses indefinitely without needing employment income, usually following the 4% rule (or similar withdrawal strategies).

FIRE Approaches Explained

Lean FIRE

Lean FIRE focuses on minimizing expenses and living frugally. The target is financial independence with minimal expenses, typically under $40,000 per year for a household.

  • Lower FIRE number required
  • Emphasis on frugality and minimalism
  • Faster path to financial independence
  • Less buffer for unexpected expenses

Regular FIRE

Regular FIRE balances saving with maintaining a moderate lifestyle. The target typically supports expenses in the $40,000-$100,000 range annually.

  • Balanced approach to spending and saving
  • More flexibility than Lean FIRE
  • Reasonable timeline to independence
  • Moderate buffer for lifestyle changes

Fat FIRE

Fat FIRE aims for financial independence without significant lifestyle compromises. The target typically supports expenses over $100,000 annually.

  • Higher standard of living in retirement
  • Substantial buffer for unexpected expenses
  • More luxuries and travel possibilities
  • Typically requires higher income to achieve

Understanding Withdrawal Strategies

The 4% Rule

The 4% rule is a guideline for how much a retiree should withdraw from retirement savings each year. This rule states that retirees can withdraw 4% of their portfolio in the first year of retirement and then adjust that amount for inflation each subsequent year.

Based on historical market performance, this approach gives a high probability that your portfolio will last at least 30 years.

Lower Withdrawal Rates

Some FIRE adherents prefer lower withdrawal rates (2.5-3.5%) for increased safety:

  • Higher probability of success over long retirements (40+ years)
  • Better protection against poor market returns early in retirement
  • More suitable for early retirees with longer horizons
  • Requires larger nest egg to generate the same income

Variable Withdrawal Strategies

Alternative approaches adjust withdrawals based on market conditions:

  • Decrease withdrawals during market downturns
  • Increase withdrawals during strong markets
  • Maintain a cash buffer for 1-2 years of expenses
  • Consider part-time work during poor market periods
