Value Added Tax (VAT) is a consumption tax placed on a product or service whenever value is added at each stage of the supply chain, from production to the point of sale. It is a broad-based tax levied on the value added to goods and services. Most countries worldwide have a VAT system, though the rates and specific applications can vary.
How VAT is Calculated
Calculating VAT typically involves two main scenarios: determining the VAT amount to be added to a price, or determining the original price before VAT was applied. Our calculator focuses on the former, which is common when issuing invoices or pricing goods.
Scenario 1: Calculating VAT to Add
When you know the price of a good or service before VAT (the net amount) and the applicable VAT rate, you can calculate the VAT amount and the total price including VAT (the gross amount).
VAT Amount = Net Amount × (VAT Rate / 100)
Total Amount (Gross) = Net Amount + VAT Amount
Alternatively: Total Amount (Gross) = Net Amount × (1 + (VAT Rate / 100))
For example, if a service costs €100 and the VAT rate is 20%:
VAT Amount = €100 × (20 / 100) = €20
Total Amount = €100 + €20 = €120
Use Cases for this Calculator
This VAT calculator is useful for:
Businesses: Accurately calculating VAT on invoices for goods and services sold.
