Free GST VAT Calculator — Inclusive Split

How to use GST / VAT Calculator with a clear next step.

Choose tax-exclusive if the entered price is before tax, or tax-inclusive if it already includes tax. Enter the applicable percentage and any supported cess, then compare the net, tax and gross amounts.

This calculator splits an entered price; it does not classify a product, verify GST registration or prepare an e-invoice. Use the India GST invoice generator when you need supplier, customer and HSN/SAC fields in a document. Check whether the source amount already includes tax. At an illustrative 20%, a tax-exclusive amount of 100 gives tax of 20 and gross of 120. Starting from an inclusive 120 instead requires dividing by 1.20 to recover net 100; subtracting 20% of 120 would incorrectly produce 96. Use the example only to verify the arithmetic and enter the rate that applies to your real transaction. Confirm whether a supported cess uses the same base and whether any rounding convention matters. If the split disagrees with an invoice, first compare inclusive versus exclusive mode, then rate and amount. A percentage result does not establish product classification, place-of-supply treatment, registration status or eligibility for credit. Keep the original price and chosen mode with the calculation. Use the appropriate invoice workflow when you need transaction identities and document fields, and verify compliance through your normal accounting process.

For an exclusive price, tax equals net price multiplied by rate divided by 100. For an inclusive price, net equals gross divided by (1 + rate/100). Check whether cess uses the same base before applying it.
