Early Retirement (FIRE) Calculator
Calculate your financial independence and early retirement needs with our advanced FIRE calculator.
How to use
Enter your current savings, yearly contributions, expected return, annual expenses, and withdrawal rate. Calculate to see how many years until you reach FIRE.
Methodology
We compute total savings needed via the safe withdrawal rule (expenses / withdrawal rate) and solve for the time required to reach that target using annual contributions and compounded returns.
- Withdrawal rate defaults to 4% (the 25× rule).
- Years solve the future value equation using a binary search on the annual compound growth.
- Results show total savings target and annual expenses for context.
