How it works

Enter the price and the VAT or GST rate. Choose whether your price is tax-exclusive (net) — and you want to add VAT — or tax-inclusive (gross) — and you want to extract the VAT. The tool computes the tax amount and the other price in real time. Common rate presets (5%, 10%, 15%, 20%, 23%) are shown for quick entry. All arithmetic runs locally in your browser.


              Net × (1 + rate) = Gross | VAT = Gross − Net

Common use cases

  • Checking how much VAT is included in a receipt total.
  • Adding the correct VAT rate to a quoted price before invoicing.
  • Comparing prices that are listed with and without tax.
