FIRE Number by Lifestyle Calculator

FIRE Number by Lifestyle lets you compare your FIRE target across three distinct spending scenarios (frugal, moderate, and luxe) side by side in real time. Instead of calculating just one FIRE number, it shows how different lifestyle choices translate into dramatically different portfolio requirements and years of work, making the trade-offs between early retirement and lifestyle spending crystal clear. The interactive scenario picker and comparison chart help you find the sweet spot between living lean to retire early versus maintaining higher spending throughout your working years, with insights that quantify exactly how much each lifestyle choice costs in terms of both dollars and additional years until financial independence.
