Use this form for anything: a number that looks wrong, a calculator you wish existed, a question about the method, or a bug on your device. Messages about incorrect figures get answered first.
This is a one-person project, so replies take a few days. Your email address is used only to reply to you — it is not added to any list, and there is no newsletter.
If a calculation looks incorrect, please include the exact inputs you used — balance, expected return, monthly withdrawal, and the currency — along with the result you saw and what you expected. That makes it reproducible, and reproducible reports get fixed quickly.
