How GST Calculation Works

GST Exclusive means the entered amount does not include tax — GST is added on top. GST Inclusive means the entered amount already includes tax — the calculator extracts the tax component from the total. For intra-state transactions, GST splits equally between CGST (Central GST) and SGST (State GST). For inter-state transactions, the full amount is charged as IGST (Integrated GST).
