How this reverse VAT calculator works
A reverse VAT calculator helps you remove VAT from a VAT-inclusive total. This is useful when you know the final amount paid and want to see how much of it is the original price and how much is VAT.
Formula
Net amount = gross amount ÷ (1 + VAT rate ÷ 100)
Example
If the total including VAT is £120 and the VAT rate is 20%, the net amount is £100 and the VAT portion is £20.
