Frequently asked questions
How do I add 20% VAT?
Multiply the net price by 1.2. £100 plus VAT is £120.
How do I remove VAT from a price?
Divide the gross price by 1.2 for 20% VAT (or by 1.05 for 5%). £120 / 1.2 = £100 net, so the VAT is £20. A quick shortcut for 20%: VAT = gross / 6.

The UK has a standard rate (20%), reduced rate (5%) and zero rate (0%). Which one applies depends on the goods or services; check GOV.UK.
