Calculating VAT from a VAT inclusive price
Sometimes products or services that are VAT taxable are sold at a price including VAT, and the VAT is not shown on the receipt. Photocopying is an example. The standard rate of VAT is 20% and to calculate the VAT exclusive price, divide the VAT inclusive price by 1.2
if your photocopying has cost you £8.20, the VAT exclusive price is £6.83, and the VAT element is £1.37.
