What to email about

A result that looks wrong. Please include the page, the numbers you entered and what you expected.
A calculator you'd like added, or a change that would make one easier to use.
Questions about this site, or about advertising and partnerships.

What to expect

XYCalc is run by one person, so replies can take a few days. I can't give personal financial, tax, legal or medical advice, but I'm happy to explain how a calculator works.

When you email, I use your address only to reply to you. See the privacy policy for details.
