VAT calculator

Choose whether to add VAT to a net amount or remove VAT from a gross amount, enter the amount and the VAT rate, and the calculator shows the net, the VAT, and the gross as you type.

Use it to add VAT on top of a net price, or to back the VAT out of a gross price, at any rate you enter.

The result updates as you type. The bar splits the gross amount into the net price and the VAT on top.

How does it work?

To add VAT, multiply the net by (1 + rate/100). To remove VAT, divide the gross by the same factor; the VAT is the difference.

VAT formula

gross=net (1+rate100)\text{gross} = \text{net}\,\left(1 + \frac{\text{rate}}{100}\right)
net
Amount excluding VAT.
gross
Amount including VAT.
rate
VAT rate as a percentage.

100 net at 20% VAT gives 20 VAT and a gross of 120. Removing 20% VAT from 120 gives 100 net.

Method & sources

VAT is calculated from the amount and rate you enter using standard add/remove formulas. Official tax authority links below explain how VAT works in each market — the calculator does not look up live rates automatically.

How we calculate

  • A single VAT rate is applied to the whole amount.
  • You supply the VAT rate yourself; it is not looked up, because rates differ by country and by category of goods.
  • 'Add VAT' treats your amount as net; 'Remove VAT' treats it as gross.
  • The currency shown follows the site language; the math is the same in every market.
  • Rounding rules required for official invoices may differ slightly from this display rounding.

Rounding

Net, VAT, and gross amounts are rounded to two decimals for display. The calculation uses full precision.

What this calculator does

VAT (value-added tax) is a percentage added to the net price of goods and services. This calculator works both ways: enter a net amount to add VAT and find the gross, or enter a gross amount to remove VAT and find the net. Either way you also see the VAT amount itself.

How to use it

  1. Pick 'Add VAT' (your amount is net) or 'Remove VAT' (your amount is gross).
  2. Enter the amount.
  3. Enter the VAT rate that applies, as a percentage.
  4. Read the net, VAT, and gross below.

A worked example

Adding 20% VAT to a net price of 100 gives 20 in VAT and a gross of 120. Going the other way, removing 20% VAT from a gross of 120 gives 100 net and the same 20 of VAT. Rates differ by country and category — for example 25% in Denmark or 19% in Germany — so always enter the rate that applies to you.

Where the VAT rate comes from

You enter the rate yourself. VAT rates differ by country and often by category — standard, reduced, and zero rates all exist — so the calculator does not assume one. Use the rate that applies to your goods or invoice.

Common mistakes

  • Removing VAT by subtracting the rate from the gross. You must divide by (1 + rate/100), not multiply, to back out VAT correctly.
  • Mixing up net and gross. 'Add VAT' starts from the net; 'Remove VAT' starts from the gross.
  • Using the wrong rate for the category of goods.

When it's useful

Quoting prices with or without tax, checking an invoice, or working out how much of a price is tax.

FAQ

How do I add VAT to a price?
Multiply the net price by (1 + rate/100). For 20% VAT, multiply by 1.20. The calculator does this for you in 'Add VAT' mode.
How do I remove VAT from a price?
Divide the gross price by (1 + rate/100). For 20% VAT, divide by 1.20. The VAT is the difference between the gross and the net.
Why can't I just subtract the rate to remove VAT?
Because the VAT was added to the net, not the gross. Subtracting the rate from the gross overstates the net and understates the VAT.
Which VAT rate should I use?
The one that applies to your country and category of goods. The calculator does not assume a rate; you enter it.
Which currency does it use?
The currency follows the site language. The calculation is identical in every market.
Can I share a calculation?
Yes. Use Share to copy a link that reopens the calculator with the same amount, rate, and mode.
