What Is a VAT Calculator?
A VAT (Value Added Tax) calculator helps you add tax to a net price (tax-exclusive) or remove tax from a gross price (tax-inclusive). It is equally useful for GST (Goods and Services Tax) in Australia, Canada, and India, and for general sales tax in the United States. Simply enter the amount and tax rate, and choose whether to add or extract the tax.

FAQ
What is the difference between VAT and GST?
VAT and GST are functionally similar — both are consumption taxes collected at each stage of the supply chain. The naming convention differs by country: "VAT" is common in Europe and the UK, while "GST" is used in Australia, Canada, and India. The calculation method is identical.
How is VAT added to a price?
Gross price = Net price × (1 + rate / 100). For example, a £100 item with 20% VAT costs £120 including tax.
How do I remove VAT from a price?
Net price = Gross price / (1 + rate / 100). For example, if you paid £120 including 20% VAT, the net price is £120 / 1.20 = £100, and the VAT amount is £20.
What does tax-exclusive vs tax-inclusive mean?
A tax-exclusive (net) price is the amount before tax — common in B2B invoicing. A tax-inclusive (gross) price already includes the tax — common in retail consumer prices. This calculator handles both directions.
