VAT Calculator

Adds VAT to a net figure or extracts it from a gross one. Both directions matter in practice: you add VAT when quoting a customer, and you remove it when reconciling a receipt that shows only the total paid.

What the VAT Calculator does

Removing VAT is where mistakes happen. Taking 20% off a gross price does not give the net figure — you divide by 1.2 instead. On a £120 gross total the VAT is £20, not £24, because the 20% was charged on the £100 net, not on the total.

How it works

Using the VAT Calculator

  1. 1Enter the amount you have.
  2. 2State whether it currently includes VAT or not.
  3. 3Enter the VAT rate — 20% is the UK standard rate.
  4. 4To add VAT the net is multiplied by 1 plus the rate.
  5. 5To remove it the gross is divided by 1 plus the rate, and the difference is the VAT.
