How VAT works

VAT (Value Added Tax) is added to most goods and services sold in the UK. The standard rate is 20%, though some goods and services qualify for the reduced rate (5%) or zero rate (0%) — for example, most food, children's clothing, and books are zero-rated.

Adding VAT takes a net price and works out what to charge including VAT: net × (1 + rate) = gross.

Removing VAT does the reverse — useful when you have a VAT-inclusive price and need to know the underlying net amount: gross ÷ (1 + rate) = net.

This calculator is provided for convenience and general guidance — for anything you're filing with HMRC, it's worth double-checking against official guidance or an accountant.
