How it works

VAT amount = net amount × VAT rate. Gross amount = net amount + VAT amount.

Three practical tips

  • Confirm which rate applies to the specific goods or services.
  • Keep invoices and use the rounding method your tax authority requires.
  • This calculator adds VAT; removing VAT requires dividing the gross amount by 1 + rate.

How do I remove 20% VAT from a gross price?

Divide the gross price by 1.20 to find the net amount; subtract net from gross to find the VAT component.
