Contractor Calculator is an independent site run by a small team. We'd love to hear from you — whether you've spotted an error in a calculation, have a suggestion for a new tool, want to report a problem, or have a general question about the site.

A note on tax questions

Please note that we cannot provide personal tax, financial, or legal advice. Our calculators offer general estimates only — for advice tailored to your circumstances, please consult a qualified accountant or tax adviser. If you spot a rate that looks out of date or a calculation that seems wrong, though, do let us know and we'll investigate.
