What is CoastFIRE?
CoastFIRE is a free retirement planning tool for people chasing financial independence. It helps you figure out when you can stop saving for retirement and let compound growth do the work. Enter your age, spending, savings, assets, return assumptions, and retirement age to see your Coast FIRE number, coast age, and progress toward full FIRE. The site also compares Coast FIRE with Barista FIRE, Lean FIRE, and Fat FIRE, and includes simple guides on topics like safe withdrawal rates, inflation, and Roth conversion ladders. It is built for planning only, with your data staying in your browser.
