Why Use FIRE Calculator?
Unlike basic retirement calculators, FIRE Calculator provides detailed projections tailored for those who aim to retire early. Whether you're growing your portfolio, planning to live off passive income, or optimizing withdrawals, this tool helps you visualize your financial future with precision.
Key Features of FIRE Calculator
📈 Growth Projection: Plan Your Capital Growth
Curious about how your investments will grow over time? Just enter your starting balance, monthly savings, annual savings growth rate, and expected return rate. The calculator generates a dynamic projection, showing how your capital will accumulate over decades. Key financial milestones — like when you’ll reach your first million — are highlighted along the way.

💰 Living Off Interest: FIRE Without Touching Principal
Want to retire while keeping your capital intact? This mode calculates when your passive income will fully cover your expenses, allowing you to live off investment returns alone. Enter your monthly retirement expenses, post-retirement return rate, and expected inflation. The tool then models your financial future and finds the earliest sustainable retirement age.

🎯 Living Off Savings: Retirement with a Drawdown Strategy
For those who prefer a more flexible approach, this mode factors in life expectancy to determine how long your capital will last. By optimizing withdrawal amounts, the tool helps you retire sooner while ensuring you won’t outlive your savings.

🖥️ How FIRE Calculator Delivers Accurate and Fast Results
Most calculators rely on simple formulas, but FIRE Calculator uses an advanced binary search algorithm for maximum precision. Instead of running 600+ simulations month by month, the algorithm quickly narrows down the optimal retirement age in just 10 iterations. This ensures lightning-fast calculations without sacrificing accuracy.

🧐 The Impact of Inflation: Why 1% Matters
Inflation can make or break a FIRE plan. Even a 1% difference in inflation rates can drastically shift your financial projections. FIRE Calculator allows you to experiment with different inflation scenarios, showing how small changes can impact your retirement timeline by years.
