Frequently asked questions
How do I add 20% VAT? Multiply the net price by 1.20. The difference from the original price is the VAT.
Is VAT the same as the gross price? No: VAT is only the tax; the gross price is the net plus VAT.
How do I remove VAT from a VAT-inclusive price? Use the reverse VAT calculator, which starts from the gross price and finds the net.
