What is VAT?
Value Added Tax (VAT) is a consumption tax placed on a product whenever value is added at each stage of the supply chain, from production to the point of sale. In the United Kingdom, businesses with a turnover exceeding the VAT threshold must register for VAT and collect it on behalf of HM Revenue and Customs (HMRC).

How to Calculate VAT
Adding VAT (Net to Gross)
Formula: Net Price × (1 + VAT Rate)
Example: If you have a net price of £100 and want to add 20% VAT, you calculate 100 × 1.20 = £120 total.
Removing VAT (Gross to Net)
Formula: Gross Price ÷ (1 + VAT Rate)
Example: If a product costs £120 including 20% VAT, you calculate 120 ÷ 1.20 = £100 net.
