What Is VAT?
Value Added Tax (VAT) is a consumption tax applied to goods and services at every stage of production and distribution.
Unlike income tax, VAT is paid by consumers while businesses collect and remit it to tax authorities.
Many countries — including the UK, most European Union countries, the UAE, Saudi Arabia, and Australia (GST) — use VAT or similar indirect tax systems.

VAT Formula
When adding VAT:
VAT Amount = Net Price × VAT Rate
Total Price = Net Price + VAT
When removing VAT:
Net Price = Gross Price ÷ (1 + VAT Rate)
These formulas are built directly into the CalcWisee VAT Calculator, so you never have to calculate them manually.

Suppose the total invoice is $240, including 20% VAT.

Frequently Asked Questions
Is VAT the same as Sales Tax?
Not exactly. Both are consumption taxes, but VAT is collected at multiple stages of production, while sales tax is usually charged only at the final sale.
Can I calculate VAT for any country?
Yes. Simply enter your country's applicable VAT percentage and the calculator adds or removes it from your amount instantly. Standard rates vary widely — for example 20% in the UK, 19% in Germany, and 5% in some regions — so always confirm the current rate for your jurisdiction before relying on the result.
Does the calculator support custom VAT rates?
Yes. You can enter virtually any VAT percentage, including reduced rates, zero-rated goods, or temporary rate changes introduced by governments. This flexibility lets you handle both standard VAT and special cases such as a 5% reduced rate on certain goods, simply by typing the rate that applies to your transaction.
