FIRE Estimate
What Is FIRE?
FIRE stands for Financial Independence / Retire Early, a movement that focuses on saving aggressively, investing wisely, and controlling expenses to achieve early retirement. The central idea is to accumulate enough wealth that your investments generate enough passive income to cover your living expenses.
The most widely used principle is the 25x Rule: multiply your expected annual expenses by 25 to determine the total savings required for financial independence. For example:
- Annual expenses: $40,000
- FIRE target: $40,000 × 25 = $1,000,000
Once your investments reach this target, you can potentially live off the returns without needing to work full-time.
How the FIRE Calculator Works
Our calculator uses the following inputs to provide accurate projections:
- Current Savings ($): Your existing investment and savings balance.
- Annual Contribution ($): How much you plan to save and invest each year.
- Annual Expenses ($): Estimated yearly expenses during retirement.
- Expected Annual Return (%): The average return rate on your investments.
The calculator applies the compound interest formula while adding annual contributions to estimate how long it will take for your total savings to reach your FIRE target. It then displays:
- Years to Financial Independence
- Total Savings at FIRE

Example Calculation
Suppose:
- Current savings: $50,000
- Annual contribution: $15,000
- Annual expenses: $40,000
- Expected return: 6%
The calculator applies the 25x rule:FIRE Target=40,000×25=1,000,000
By factoring in annual contributions and investment growth:
- Year 0: $50,000
- Year 1: $50,000 + $15,000 + 6% growth ≈ $69,000
- Year 2: $69,000 + $15,000 + 6% growth ≈ $91,140
- … and so on
Result: Approximately 22 years to reach financial independence, with total savings exceeding $1,000,000.
