What is GST / VAT Tax Calculator?
The GST Calculator adds tax to a price or extracts tax from a price that already includes it. In exclusive mode, 18% GST on 5,000 is 900, for a total of 5,900. In inclusive mode, the tool works backwards from the total to show the net amount and the tax inside it. Rates of 5%, 12%, 18% (standard) and 28% are available, matching India’s GST slabs, and the same maths applies to VAT and sales tax anywhere.
