FAQ
What is a VAT reverse calculation?
A VAT reverse calculation finds the net price and VAT amount when you start from a VAT-inclusive gross price. It is commonly used to calculate VAT backwards or convert gross to net.
How do you reverse-calculate VAT?
Divide the gross amount by 1 + (VAT rate / 100). For example, for a £120 gross price at 20% VAT: net = 120 ÷ 1.20 = £100, VAT = £20.
What is the difference between a VAT reverse calculator and a VAT removal calculator?
They perform the same arithmetic. The reverse calculator emphasises finding the original net price, while the removal calculator emphasises how much VAT is stripped out of a price. Both start from a gross amount.
Can I use this for any VAT rate?
Yes. Use the preset buttons for common UK (20%, 5%, 0%) and Italy (22%, 10%, 4%) rates, or type any custom VAT percentage directly into the field.
Is this the same as “extracting VAT”?
Yes. Extracting VAT, backing out VAT, removing VAT and reverse VAT all refer to the same operation: recovering the net amount from a VAT-inclusive price.
