Frequently Asked Questions
Everything you need to know about this tool, how it works, and privacy.
How does the VAT calculator work?
Enter the net amount, which is the price before VAT, and the VAT rate as a percentage. The calculator uses VAT amount = net amount x (rate / 100) and total including VAT = net amount + VAT amount. For example, a 1,000 net amount at a 20% rate gives 200 VAT and a total of 1,200.
Which VAT rate should I use?
Use the rate that applies to your country and the product or service you are purchasing. Standard, reduced, and zero rates vary by jurisdiction and product type, so check the relevant tax authority for the current rate before relying on a result.
Which inputs are accepted?
Enter a net amount greater than zero and a VAT rate between 0% and 100%. Amounts are rounded to two decimals for display, and missing or non-numeric entries show a clear error instead of a result.
Do my amounts leave my browser?
No. The calculation runs locally in your browser. CodeASystem does not upload or store the amounts or rate you enter.
