Corrections to the maths are the most welcome kind of message and get dealt with first.

What to include
Reporting an error in a calculator
Please include the page, the exact inputs you used, the result you got, and the result you expected — along with the source you are checking against if there is one. That is usually enough to reproduce and fix it the same day.
Requesting a new calculator
Tell us what you are trying to work out and what you currently do instead. Tools that solve a real recurring problem get built; tools that exist mainly to fill a gap in a list do not.
Advertising
Advertising is served programmatically. For direct placement enquiries, email the address above with your requirements and expected volumes.
Privacy requests
For access, correction or deletion requests relating to personal data, see the privacy policy and email the address above with "Privacy request" in the subject line.
Response times
This is a small operation, so expect a few days rather than a few hours. Reports of incorrect results are prioritised above everything else.
