Estimates only

Every calculator on PayToolkit is provided for general guidance and estimation purposes only. Results are based on the HMRC rates and thresholds described in our Methodology, applied to the figures you enter.

Not financial or tax advice

PayToolkit is not a firm of accountants, tax advisers, or financial advisers, and using our calculators does not create an advisory relationship. For decisions with significant financial consequences, we recommend speaking to a regulated accountant or tax adviser who can review your full circumstances.

No liability for reliance on results

While we take care to keep calculators accurate and up to date, PayToolkit accepts no liability for loss arising from reliance on calculator results. Always cross-check important figures, particularly for Self Assessment submissions, using HMRC's own tools or a qualified professional.
