How This Calculator Works
This FIRE age calculator uses your spending target and withdrawal rate to estimate the portfolio you need. From there, it projects your current portfolio forward with monthly investing and compounded growth until the plan reaches that target.
If you want an even simpler output, the Years to FIRE Calculator focuses on time remaining. If you want a more complete planning page with richer milestones, open the FIRE Calculator.
