It's an investing calculator that shows you not just the investment journey, but also how your balance behaves once you stop saving and start withdrawing. My goal is to inspire people to invest their money and learn about FIRE by showcasing how much earlier you could retire with some aggressive saving.
I hope some of you find it as beautiful and useful as I do. I'd also like to ask for feedback on the behaviour, usefulness, the math/assumptions (did I miss anything obvious?) etc.
Thanks! /Felix Schulze
