$120.00 gross, with $20.00 of VAT added
$100.00 net plus 20.0% VAT is $120.00 gross, made up of $20.00 of VAT.

- This carries no rate table of its own: whatever rate was typed is used exactly as typed, and is only as current as your own check of the European Commission's page for it.
- It knows nothing about which goods or services a given rate applies to, or any country-specific reduced or exempt category.
- It does not know whether this transaction is subject to EU VAT at all - a cross-border B2B sale may fall under reverse charge instead, which is a different question this page does not ask.
What this is
This VAT calculator does three things with a rate you type in yourself: adds VAT to a net amount, removes VAT from a gross amount to get back to net, or - given both a net and a gross amount already - works out the VAT amount, and the rate, that sits between them.
VAT is added to a net amount by multiplying it by the rate; it is removed from a gross amount by dividing, not by the same multiplication run backwards - gross divided by (1 + rate), not gross minus (gross × rate), is what gets back to the right net figure.
Given both a net and a gross amount already, the VAT amount is simply the difference between them, and the rate that produced it can be read back out of the two figures - useful for checking that an invoice already in hand used the rate it should have.
How to read the result
The facts row always shows all three figures together - net, VAT and gross - whichever two were typed in, so the relationship between them is visible rather than only the one number asked for.
Nowhere on this page is a rate supplied for you: the rate field is typed in by hand, and the source linked below is the European Commission's own page for what each member state currently charges - confirm the rate there before relying on the arithmetic here with it.
Common mistakes
What goes wrong most often, and how to tell.
- Removing VAT by subtracting a percentage instead of dividingA gross amount already has VAT folded in, so taking the rate off a percentage of the gross figure over-removes it - the correct net amount is the gross divided by (1 + rate), not the gross minus (gross × rate).
- Trusting a rate this page remembered from last timeThis calculator carries no rate table of its own and never did - every rate used here is whichever one was typed into the box for that calculation, and nothing is carried over from an earlier visit or cached anywhere.
- Assuming every EU sale is subject to the rate typed in at allA cross-border B2B sale within the EU may fall under reverse charge instead of either party actually paying VAT at the point of sale - a different question entirely, and one this page does not try to answer.
Questions
What people ask about this tool.
- Wherever it was typed into the rate field - this page carries no rate table of its own, and never applies a rate it was not given. The European Commission's own page, linked below, is where to confirm the rate that currently applies before relying on the figure this calculator gives back.
- By dividing the gross amount by one plus the rate as a fraction - a gross of $120 at a 20% rate divides by 1.20 to give a net of $100, with the $20 difference being the VAT. Subtracting 20% of the gross figure instead gives the wrong, smaller net amount.
- Yes - choose "work out the VAT, given both amounts" and enter the net and the gross you already have. The VAT amount is simply the difference between them, and this also shows the rate those two figures imply, which is a quick way to check an invoice used the rate it should have.
- No. Rates differ by member state and by category of goods or services, and this page has no table of either - it only does the arithmetic on the rate typed into the box, which is why confirming that rate against the official source first matters.
