How do I extract VAT from a gross amount?

Choose “Extract”. The calculator divides the amount by (1 + rate/100) to get the net price, and the difference is the VAT.

Which rate should I use?

20% by default — a standard rate in many countries. If yours differs (say 10% or 18%), just type your value.

Does it work for other sales taxes?

Yes. The logic of adding and extracting a percent is the same for VAT, GST, sales tax and similar taxes — only the rate changes.

Does it round the cents?

The result is shown to two decimal places. For accounting documents, follow your jurisdiction's rounding rules.

What's the difference between net and gross?

Net is the price before VAT; gross is the price including VAT. The calculator shows both, plus the tax amount.

Why isn't adding then extracting 20% the same amount?

The percent is taken from different bases. Adding 20% to 100 gives 120; extracting 20% from 120 gives back 100 — the tool handles each direction correctly.

Why it's useful

VAT is baked into almost every purchase, but invoices and receipts show it differently: sometimes the price is net, sometimes tax is “included”. Freelancers, business owners, and careful shoppers often need to know exactly how much the tax is.

This calculator works both ways: it adds VAT to a clean amount and extracts the tax from an amount that already includes it. The rate is adjustable — handy for different countries where VAT varies, or for goods with a reduced rate.

FAQ

Choose “Add”, enter the net amount and the rate. Tax = amount × rate / 100, and the total = amount + tax.
