VAT calculator

How it works

Choose a country to load its VAT rates, or pick Custom rate and type your own percentage.
Type an amount and say whether it excludes or includes VAT. The calculator works both ways.
For an invoice, switch to Invoice lines, fill in the names, number and date, add rows, then print the overview or copy it as text.

Including or excluding VAT

From a net price, the VAT is net x rate / 100 and the total is net x (1 + rate / 100). From a price that already includes VAT, the net amount is total / (1 + rate / 100) and the VAT is the difference. At 21%, 121.00 including VAT is 100.00 net plus 21.00 VAT. Amounts are rounded to cents, the way most invoices show them.

A simple invoice overview

In Invoice lines mode every row has a description, a quantity, a unit price and its own VAT rate. The overview groups the lines by rate, so you see the subtotal, the VAT at each rate and the total, with a reverse charge option for business customers abroad. Print it, save it as an image or copy it as text into an email. It is a handy check, not a replacement for your accounting software or tax adviser.

Frequently asked questions

How do I remove VAT from a price?

Choose Including VAT and type the price. The calculator divides it by 1 plus the rate, so at 21% it divides by 1.21, and shows the net amount and the VAT separately.

Why not just take 21% off the total?

Because the VAT was calculated on the net amount, not on the total. 21% of 121.00 is 25.41, but the real VAT is 21.00. Dividing by 1.21 gives the right answer.

Are my invoice details sent anywhere?

No. Everything is calculated in your browser, and your last settings and lines are only kept in this browser's local storage.
