simpleFIRE
simpleFIRE puts three FIRE calculators in your pocket. Move a slider and see what you'll have, when you can stop working and how long your money will last.
- Projection, Time to FI and Drawdown — growth with contributions, the month you reach your target, and how long your portfolio lasts once you live off it.
- Monte Carlo, historical or a fixed rate — 5,000 simulations of your plan, or a backtest through every period of real market history, the way the Trinity study tested the 4% rule.
- Every number explained — a chart you can drag year by year, and every assumption behind the result.
- Private by design — no account, no tracking; everything is calculated on your device.
Projection is free; Premium is a one-time purchase. More on simplefire.app.
