Runs locally · nothing is uploaded

0.00Net amount
0.00VAT (20%)
0.00Gross amount

Features

Both directions

Add VAT to a net amount, or remove it from a gross price to find the net and the tax inside it.

Rounded to the cent

Worked in whole cents, so net plus VAT always equals the gross exactly.

Type it your way

Comma or dot decimals and thousands separators are understood, and results answer in the same style.

How to use

  1. 1 Choose Add VAT for a net amount, or Remove VAT for a price that already includes it.
  2. 2 Type the amount, then pick a rate or type any rate yourself.
  3. 3 Read the net, VAT and gross amounts, or copy all three at once.

Common use cases

  • Pricing a product or service with VAT included
  • Finding the VAT inside a receipt for your expenses
  • Checking the totals on an invoice before sending it
  • Working out the net price behind a gross quote
  • Comparing prices across countries with different rates

About this tool

VAT is a percentage added on top of a net price. Adding it is a simple multiplication; taking it out of a price that already includes it is where mistakes happen, because the tax is a share of the net amount, not of the gross.

This calculator does both, works in whole cents so the three figures always add up, and reads amounts typed with a comma or a dot. The same math works for GST and any sales tax charged as a percentage.

This tool is built by ToolClack and, like everything we make, it is local-first: your data stays in your browser.

Frequently asked questions

How do I work out the VAT in a price that includes it?

Choose Remove VAT and type the gross price. The net is the gross divided by one plus the rate: at 20%, a price of 120.00 holds 100.00 net and 20.00 of VAT. Taking 20% of 120 would give 24.00, which is wrong.

How are the results rounded?

To the nearest cent. The VAT (or the net, when you remove VAT) is rounded, and the third figure is worked out from the other two, so they always add up. On invoices with many lines, some countries round per line and others per total.

Can I type 1.234,56 or 1,234.56?

Yes. When a comma and a dot both appear, the last one marks the decimals. A single comma or dot followed by exactly three digits, as in 1,500 or 1.500, is read as a thousands separator. Results use the style you type.

Which rate should I use?

The one that applies to what you sell and where. Most European standard rates sit between 17% and 27%, with reduced rates for items such as food or books. The presets cover common rates; type any other, decimals included.
