Report an Error

Accuracy is our top priority. If you notice a calculation that doesn't look right, an outdated rate, or a typo, please let us know. When reporting an error, it helps if you include:

  • The name of the calculator
  • The values you entered
  • The result you received
  • What you expected the result to be
  • Your source for the expected result (e.g. HMRC, your accountant)

We investigate every report and typically resolve issues within 24-48 hours.

Suggest a Calculator

We're always expanding our collection. If there's a calculator you'd find useful that we don't currently offer, let us know. We prioritise suggestions based on:

  • How many people would benefit from it
  • Whether reliable official data sources exist
  • How complex the calculation is to implement accurately
