VAT calculator by country

How it’s calculated

VAT is charged as a percentage of the net (pre-tax) price. To add it, multiply the net amount by the rate; to find the net amount inside a tax-inclusive price, divide the gross amount by 1 plus the rate.

A common mistake is to remove VAT by subtracting the rate from the gross price (e.g. 119 − 19% = 96.39). That is wrong — the correct net amount is 119 ÷ 1.19 = 100.

  • Gross = Net × (1 + rate ÷ 100)
  • VAT = Net × rate ÷ 100
  • Net = Gross ÷ (1 + rate ÷ 100)
  • VAT included in a gross price = Gross − Net = Gross × rate ÷ (100 + rate)

Frequently asked questions

How do I add VAT to a price?

Multiply the net price by 1 plus the VAT rate. At 20%, a net price of 100 becomes 100 × 1.20 = 120, of which 20 is VAT.

How do I remove VAT from a gross price?

Divide the gross price by 1 plus the VAT rate. At 20%, 120 ÷ 1.20 = 100 net, so the VAT included is 20. Don’t simply subtract 20% of the gross price — that gives the wrong result.

Which VAT rate should I use?

Most goods and services use the country’s standard rate. Reduced rates only apply to categories defined by law (often food, books, medicines or passenger transport). If you are not VAT-registered, you usually charge no VAT at all.

Does this work for GST and other consumption taxes?

Yes. GST, consumption tax and similar taxes are calculated the same way — just pick the country or enter the rate.

Are the rates up to date?

Rates are reviewed regularly, but tax rules change. Always confirm the rate with the tax authority before relying on it for filings.
