How GST is calculated
Excluding GST: GST = Amount × Rate%. Including GST: Base = Amount ÷ (1 + Rate%), GST = Amount − Base. For sales within the same state, GST splits equally into CGST and SGST; inter-state sales attract IGST at the full rate.
Common rates: 5% (essentials, transport), 12% (processed foods, some services), 18% (most goods & services — the default rate), 28% (luxury/sin goods). 0.25% and 3% apply to rough precious stones and gold respectively.
