VAT formulas
Add VAT: gross = net × (1 + rate ÷ 100).
Remove VAT: net = gross ÷ (1 + rate ÷ 100), and VAT = gross − net.
The same formulas work for GST and sales tax. In the US, sales tax is usually added at checkout and varies by state and city.
Frequently asked questions
How do I remove VAT from a price?
Divide the gross price by 1 plus the rate. With 21% VAT: €121 ÷ 1.21 = €100 net, so the VAT is €21. Simply taking 21% off €121 gives the wrong answer (€95.59).
How do I add VAT?
