How this calculator works

VAT rates and treatment vary by country, product, customer, and transaction. This tool performs arithmetic using your selected rate rather than choosing a rate for you.

Formula

Gross = net × (1 + VAT rate ÷ 100)

Example

At 20% VAT, a net amount of 100 produces 20 VAT and a gross amount of 120.

Frequently asked questions

How do I remove VAT from a gross price?

Divide the gross price by one plus the VAT rate, then subtract that net amount from the gross amount to find VAT.

Does this calculator choose the correct VAT rate?

No. Select the rate appropriate to the transaction after checking current rules.
