Terms of Use

By using this site you accept these terms. They exist to be clear about what our calculators are — and what they are not.

Estimates, not advice. Results are estimates based on the published 2026/27 UK rates and standard assumptions. They do not constitute financial, tax, legal or employment advice, and they do not replace your payroll software, accountant or HMRC guidance.

Accuracy. We source every figure from GOV.UK and review rates each tax year, but we cannot guarantee that every result is correct for your specific circumstances. Verify figures against GOV.UK before making payroll, hiring or contractual decisions.

Liability. To the extent permitted by law, we accept no liability for loss arising from reliance on calculations on this site.

Acceptable use. You may use the calculators freely for personal and business purposes. Do not scrape, misrepresent the results as official HMRC figures, or embed the tools without permission (embed licensing is coming — see the contact page).
