The GOV.UK calculator is the official source and worth cross-checking against for peace of mind, but it's limited to core PAYE calculations. MoneySavingExpert is a trusted, well-established option for a quick salary check. UK Tax Tools offers a similarly broad calculator library to PayToolkit. Where PayToolkit differs is combining that breadth of calculators with a connected Expense Tracker and Tax Dashboard, so you're not just calculating a number once — you can track it through the year.

FAQ

Is PayToolkit as accurate as the official GOV.UK calculator?

PayToolkit uses the same official HMRC rates and thresholds as the GOV.UK calculator. For anything important, we recommend cross-checking against gov.uk directly, which we link to in our Tax Calculation Sources page.

Do I need to sign up to use any of these?

No — PayToolkit, the GOV.UK calculator, MoneySavingExpert, and UK Tax Tools are all usable without creating an account.
