Enter a figure and pick a rate; the VAT amount, the net and the gross come out together, so a quote and its tax break down in one glance. The calculation is a pure number, so it runs here on the page with no account and no data sent anywhere.

VAT (value added tax) is added to the net price of most goods and services. In Belgium, the standard rate is 21 %, with reduced rates of 12 % (notably food service) and 6 % (food, medicines, renovation of buildings over 10 years old). In France, the standard rate is 20 %, alongside the 10 %, 5.5 % and 2.1 % rates.
This calculator works in both directions: add VAT to a net amount to get the gross price, or start from a gross amount to recover the net base and the VAT amount — handy for expense reports and tax filings.

Frequently asked questions
How do I calculate a gross price from a net amount?
Multiply the net amount by (1 + rate). Example in Belgium at the standard rate: €100 net × 1.21 = €121 gross.
How do I get the net amount back from a gross price?
Divide the gross amount by (1 + rate). Example: €121 gross ÷ 1.21 = €100 net. Never simply subtract 21 % from the gross — the result would be wrong.
What are the VAT rates in Belgium and France?
Belgium: 21 % (standard), 12 % and 6 % (reduced). France: 20 % (standard), 10 %, 5.5 % and 2.1 % (reduced). Some operations are exempt or subject to reverse charge.
