The FIRE Planner (Financial Independence, Retire Early) is a tool designed to help you calculate how long it will take to achieve financial independence and retire early based on your personal financial details. By entering your annual income, expenses, savings rate, expected return on investments, and withdrawal rate, the planner will estimate the size of the portfolio you need to retire comfortably and the number of years it will take to reach your FIRE goal. This tool is perfect for anyone looking to understand how their current financial habits and future goals align with early retirement.
