Some searches lead here when you're really after another service's own tool. To be clear:
- An official HMRC tax or VAT tool – the official versions are on GOV.UK. Our tax rate calculator is an estimation tool.
- Trade union fees – the percentages vary by union. Check your own rate on your union's website and enter it into the salary calculator.
- Blood alcohol calculator – blood alcohol depends on many variables. Our punch calculator tells you a drink's strength, not your blood alcohol level.
- Did you mistype a search? "Discont" means discount and "pivot tabel" means pivot table – the links above take you to the right pages.
