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

FIRE Calculator – Plan Your Path to Financial Independence Retire Early
Are you dreaming of leaving the 9-to-5 grind and living life on your own terms? The FIRE calculator is your first step toward achieving Financial Independence, Retire Early. This tool gives you a crystal-clear roadmap to reach your retirement goal sooner than traditional plans allow.
By entering your income, expenses, savings rate, and target lifestyle, the FIRE calculator reveals when you can walk away from your job — not at 65, but maybe at 45, 40, or even earlier.
What Is a FIRE Calculator?
A FIRE calculator helps you estimate the time it will take to reach financial independence based on your:
- Annual income
- Annual expenses
- Current savings
- Yearly investment returns
- Savings rate
- FIRE target number (your financial independence goal)
Once your net worth hits the target number, you’ve reached FIRE — meaning your investments can support your lifestyle indefinitely without needing active income.
How Does the FIRE Calculator Work?
The FIRE calculator uses two critical formulas:
- FIRE Number = Annual Expenses × 25
(Based on the 4% Safe Withdrawal Rule) - Time to FIRE = Years needed to save & invest until your net worth hits FIRE number
The calculator factors in compounding returns, inflation, and annual savings growth — giving you a realistic projection of your financial freedom date.
🧮 Example: FIRE Scenario
| Annual Income | Annual Expenses | Savings Rate | Current Savings | Investment Return | FIRE Age |
|---|---|---|---|---|---|
| $80,000 | $35,000 | 56% | $25,000 | 7% annually | 43 yrs old |
Result: If you’re 28 today and maintain this lifestyle, the FIRE calculator shows you can retire by age 43!
