What is FIRE?

FIRE stands for Financial Independence, Retire Early. The goal is to build a large enough investment portfolio that withdrawals from it can sustainably cover your living expenses indefinitely, without needing traditional employment income.

The Formula

Your FIRE Number = Annual Expenses ÷ Safe Withdrawal Rate (commonly 4%). This calculator also projects your current savings forward, adding your annual contributions and compounding at your expected return, to estimate how many years it may take to reach that number.
