Formula
- Add VAT:
gross = net × (1 + rate ÷ 100),VAT = gross − net - Remove VAT:
net = gross ÷ (1 + rate ÷ 100),VAT = gross − net
Worked example
Adding 20% to a net price of 200: 200 × 1.20 = 240, so VAT is 40. Removing 20% from 240: 240 ÷ 1.20 = 200 net, VAT 40.
Frequently asked questions
How do I add VAT to a price?
Multiply the net price by 1 plus the rate. At 20%, 200 × 1.20 = 240, so the VAT is 40.
How do I remove VAT from a price?
Divide the gross price by 1 plus the rate. At 20%, 240 ÷ 1.20 = 200, so the VAT is 40. Do not subtract 20% of 240, which would give 192.
Why is removing 20% not the same as subtracting 20%?
VAT is charged on the net price, not on the gross one. VAT is 20% of 200 (40), which is only 16.7% of 240.
Which VAT rate should I use?
Use the rate that applies to your goods or service in your country. Rates differ between places and products, so check with your tax authority.
