How this calculator works

The taxable invoice value is unit taxable price × quantity. GST is then applied using the selected rate and shown as CGST + SGST/UTGST for intra-State or IGST for inter-State.

GST structure note

For a typical intra-State taxable supply, GST is split into CGST and SGST/UTGST. For an inter-State taxable supply, IGST applies. The applicable rate depends on the classification and current notifications, so the rate is editable rather than guessed from the product or service name.
