Contact
Found a wrong number, a broken link or an unclear explanation? We would like to hear about it.
Email the site owner
Email is the only contact channel. Messages are read by the person who maintains the calculators, and a reply usually follows within a few business days.
Why there is no contact form
A form would send your message to a server and create a data-handling obligation. This site has no backend at all, so a plain email link keeps things simple and keeps calculator data out of any database. Your email client handles the message; we never receive calculator inputs.
Reporting a calculation issue
To help us reproduce the problem, please include:
- The page address (URL) where you saw it.
- The inputs you used, listed as plain numbers.
- The result you saw and the result you expected.
- Your browser and device, if the page looked broken.
Please do not send personal financial documents, account numbers, tax returns, identification or other sensitive information. We cannot store or act on them.
