Work out what to charge with VAT on top, or pull the VAT back out of a gross price — the two calculations freelancers and shoppers actually need.

What it does

The VAT Calculator does the two calculations that actually come up in real life: adding VAT on top of a net price (what to charge, what to write on an invoice) and pulling the VAT out of a gross price (what a receipt was actually made up of, or what the pre-tax cost of an expense was). It handles any rate, so it works whether you're on 21% in the Netherlands, 20% in the UK, 19% in Germany or a reduced rate for food and books.

How to use it

  1. Select your calculation mode: 'Add VAT' to calculate the gross price, or 'Remove VAT' to find the net price.
  2. Enter the price amount in the input field.
  3. Set the VAT rate percentage — common rates include 20% (UK), 21% (NL/BE), 19% (DE).
  4. View the results instantly: VAT amount, net price, and gross price.
  5. Adjust any value to compare different scenarios — results update in real-time.

Key features

Why it helps

Freelancers reach for this while writing an invoice; shoppers use it to see the pre-tax price of a big purchase; accountants use it to reverse-check what a supplier billed. Getting the two directions right matters — adding 21% to 100 gives 121, but 21% of 121 is not the VAT inside it. Doing the math here beats doing it in your head at the end of the month.
