Compound interest calculator for planning financial independence. Enter your age, retirement goals, savings, and expected returns to see when you can “coast” to retirement — the point where your investments can grow enough on their own to meet your target income.
The app adjusts for inflation, lets you choose your target withdrawal rate, and includes calculations with ongoing savings. Results are presented in a clear, year by year table so you can track your progress easily.
