This calculator helps you determine your financial independence number (also known as your FI or FIRE number), which is the amount of money you need for the rest of your life.
While you can’t control all of the variables (like inflation and investing returns), you can control most of the variables, like how much money you spend and how much money you make. You might need less money than you think.
You can use this calculator to estimate your own FIRE number. But it’s important to not stress out about it and understand that your number will and should change as you change. The key is to calculate an estimate and to get comfortable with adjusting your own numbers as you grow and your life changes.
