What is VAT and GST Calculator?

VAT (value added tax) and GST (goods and services tax) are sales taxes added to the price of most goods and services. Businesses often need to move between prices with and without tax.

What this tool does

Takes an amount and a tax rate. If the amount does not include tax it adds the tax. If it does include tax it works backwards to find the price before tax and the tax part.

How to use it

  1. Enter the amount and the tax rate.
  2. Say whether the amount includes tax or not.
  3. Read the price without tax, the tax and the price with tax.

Did you know?

  • To remove a 20 percent tax you divide by 1.2, not subtract 20 percent.
  • Tax rates differ by country and by product, so check the correct rate for your case.
