Frequently Asked Questions

How do I add VAT to a price?

Enter the net (pre-VAT) amount and the VAT rate. The calculator multiplies the amount by the rate to find the VAT, then adds it to give the gross total.

How do I remove VAT from a gross amount?

Enter the VAT-inclusive amount and the rate; the calculator works backwards to show the original net amount and the VAT portion included.

Can I use any VAT rate?

Yes. Use the presets for common rates or type any custom percentage your country or product requires.

Is the calculator free and private?

Yes. It's free, requires no sign-up, and calculates everything in your browser.
