FIRE Calculator is a free, browser-based tool that helps you visualize your path to Financial Independence, Retire Early (FIRE). Adjust your age, savings rate, expected returns and withdrawal rate to see an estimated FIRE number, target retirement age, and years remaining.
All calculations run entirely in your browser — we don't collect or store the financial figures you enter. The tool is built to be simple, fast, and usable from anywhere in the world.
