How to add VAT

Multiply the price by 1.2. For example, £100.00 + 20% VAT = £120.00.

How to remove VAT

Divide the total by 1.2. It is not the same as taking 20% off. For example, £120.00 ÷ 1.2 = £100.00 before VAT.

Quick UK method: the VAT inside a price that includes 20% VAT is 1/6 of it. £120.00 ÷ 6 = £20.00.
