Free Invoice Generator

VAT calculator

Add VAT to an amount, or take it back out of a total that already includes it. Removing VAT is a division rather than a subtraction, and subtracting is the usual mistake.

What you're working out
The amount

The figure you are charging before any VAT is added.

Round numbers to save typing. They aren't recommendations, so enter the rate that applies to your invoice.

Used only if you press Create this invoice, as the name of the line it becomes.

What the VAT calculator does not do

  • It doesn't know your VAT rate. There's no country list here on purpose. Rates vary by country, by product and by customer, and a table of them on this page would be tax advice that goes out of date the day a rate changes. Check the current rate with the tax authority: GOV.UK for the UK, and the European Commission's list for EU countries.
  • It doesn't decide whether you have to charge VAT at all. Registration thresholds, reverse charges (where the customer accounts for the VAT instead of you) and exemptions are questions for your tax authority or your accountant.
  • It doesn't keep anything. Nothing is written to your browser's storage while you use it and nothing is sent to us, so the figures are gone when you close the tab. Press Create this invoice if you need a document: the figures are handed to the invoice generator in this tab, cleared as soon as it opens, and saved there as a new invoice alongside any you already have.

If the tax is called GST, the GST calculator is the same sum under that name. For a whole invoice rather than one amount, use the invoice calculator, which takes line items, a discount and a deposit. If you bill by time, the hourly invoice calculator takes hours and a rate. For a tax quoted exclusive of the price, and for a combined rate made of several jurisdictions, use the sales tax calculator. Once the VAT figure is right, the invoice requirements checker lists what else a VAT invoice must show in your country, and the VAT number checker checks the VAT number that goes on it.
