How it works

To add VAT: gross = net × (1 + rate ÷ 100). To remove VAT: net = gross ÷ (1 + rate ÷ 100). VAT is gross minus net. The display rounds to two currency decimal places; your invoice rounding policy may differ.

Three practical tips

  • Confirm which rate applies to the specific goods or services using the official VAT-rate guidance.
  • Keep invoices and use the rounding method your tax authority requires.
  • Removing 20% VAT is not the same as taking 20% off the gross amount.

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.
