About GST Calculator

The Goods and Services Tax (GST) is a value-added tax used in India. It is split into Central GST (CGST) and State GST (SGST) for transactions within one state, or charged as Integrated GST (IGST) for transactions between states or imports.

Rates in real invoices may include cess on certain goods, or different rates for composition dealers, so use the calculator as a quick planning estimate and verify the figures on any actual bill.

Frequently asked questions

When should I choose CGST+SGST instead of IGST?

Use CGST+SGST when the supplier and buyer are in the same state. Use IGST when the states differ or for imports.

Can I use it for composition scheme invoices?

No. Composition dealers pay tax at different rates and usually cannot charge GST separately on the invoice.

Why are CGST and SGST equal?

By default the central and state portions are equal, each half of the total GST rate. This tool shows the standard split.
