About

This is a small, fast GST calculator for India. Enter an amount, choose whether you are adding or removing GST, pick the rate that applies, and read the result — including the CGST, SGST or IGST split.

Every calculation runs in your browser. Nothing you type is sent anywhere, and there is no account to create.

The suggested rates are shortcuts, not a ruling on what applies to your goods or service. Any rate can be entered manually.
