This is a static site with no form backend, so email is the only channel. It is run by one person, so replies typically take a few days — thanks for your patience.

When reporting a calculation issue, the fastest way to help is to use the “Copy shareable link” button in the calculator and paste the link into your email — it encodes your exact inputs so the scenario can be reproduced immediately.
