About this FIRE calculator
Financial Independence, Retire Early is a movement built on saving a large share of your income and investing it so that your assets can fund your living expenses. The FIRE number is the corpus you need, usually 25 times your annual expenses, assuming a 4% withdrawal rate.
Enter your income, expenses, savings, expected return and withdrawal rate. The tool computes your FIRE number and estimates how many years it will take to reach it, and the age at which you get there.
The estimate assumes a constant return and that you invest all surplus. Real returns and expenses vary. Use it to set a savings target and track progress.
