We are glad to hear from you, above all when a calculator looks wrong or a law has changed. Write to us at the address below.

Reporting a wrong result

If you think a calculator gave a wrong result, please send us:

  • The page link, ideally the link to the result itself (the “Copy link” button under the slip).
  • The result you expected and where it comes from: an official calculator, your employer’s settlement, or a court ruling.
  • Your source if you have one: an article number, an official page or a recent decision.

We check every report against the law. If we confirm a mistake, we correct the rules file and update the review date on the page.

Before you write

  • We cannot advise on your own legal, tax or religious case. For a dispute with your employer, turn to the labour ministry in your country or a qualified lawyer.
  • Please do not send sensitive data such as ID numbers, contracts or bank statements. We only need the figures.
  • We read every message, but a reply may take some time.

The privacy policy explains what we do with your message and your email address.
