About the vat / gst calculator
Calculate VAT or GST amounts and tax-inclusive or tax-exclusive prices using your local rate. This tool is designed to provide a quick estimate with clear, easy-to-understand results. It runs in your browser and does not require you to create an account.
How the calculation works
For exclusive mode, tax is added to the net amount. For inclusive mode, tax is extracted from the gross amount.
Example
At a 20% rate, a net amount of 100 becomes 120 including tax.
When should you use it?
