Frequently asked questions
What are the UK VAT rates?
20% standard rate on most goods and services, 5% reduced rate (e.g. domestic energy), and 0% zero rate (e.g. most food, children's clothes, books) — enter the rate that applies to what you're calculating.
How do I extract the VAT from a price that already includes it?
Choose 'Inclusive of VAT' — the calculator divides by (1 + rate) to find the net amount, then shows VAT as the difference, rather than simply multiplying the gross price by the rate (which would overstate the VAT).
