How this calculator works

Enter an amount and a rate. Choose whether the amount already includes GST or not: adding GST to ₹10,000 at 18% gives ₹11,800, while removing GST from ₹11,800 gives a taxable value of ₹10,000.

For a supply within a state, the tax splits equally into CGST and SGST or UTGST. For a supply between states, the same total is charged as IGST instead, and the split does not apply.

Some goods also attract compensation cess on top of GST. Where it applies, it is charged on the taxable value in the same way as the tax.

What is the difference between CGST, SGST and IGST?

On a supply within a state the tax is split equally between the Centre and the state as CGST and SGST. On a supply between states the whole amount is charged as IGST. The total rate is the same either way.

Which rate applies to my product?

The rate follows the classification of the goods or service under the rate schedules. Classification is not always obvious and getting it wrong creates a demand later, so confirm it rather than assume.
