Financial Independence, Retire Early
Your FIRE Path Planner
Enter your financials, and let Monte Carlo simulation reveal your future—replacing guesswork with probability to drive your path to financial freedom.
📊
Configure parameters on the left and run simulation to view your future.
🧠 Core Concept
- No Straight Lines: The market never grows by a fixed 8% annually. It is highly volatile and unpredictable.
- Parallel Universes: By running thousands of random path simulations, we map out every possible direction your wealth could take.
- Probability Over Guesses: Instead of a single final number, we provide confidence intervals showing what is highly likely.
⚙️ Engine Mechanics
- Risk/Return Binding: Built-in portfolios enforce historical stock/bond return & volatility metrics, preventing naive inputs with zero downside.
- Dynamic Lifestyle: Crossing the FIRE target line automatically triggers "Retirement Phase"—halting savings and initiating cost-of-living withdrawals.
- Sequence of Return Risk: Stress tests accurately target crashes hitting immediately after you retire, mimicking true vulnerability.
📊 Interpreting Charts
- Median Curve (P50): The most likely standard outcome (50% probability above, 50% below).
- Probability Bands: The darkest band covers the highly-likely core outcomes, while the lighter bands show extreme luck and deep misfortune borders.
- FIRE Target Line: Based on the 4% Rule (25× annual expenses) and shifting upwards to account for ongoing inflation.
⚠️ Planning Advice
- Avoid Prophecy Trap: Models are based on statistical historical boundaries but cannot predict real-world Black Swan events.
- Defend the Baseline: Do not obsess over high-end potential. Ensure you can survive the "Worst Case (P5)" and extreme stress test scenarios.
- Calibrate Annually: As you age and your assets compound, re-run this simulation yearly to recalibrate your trajectory.
