How GST add / remove works
Add GST: tax = amount × rate / 100, total = amount + tax. Remove GST: exclusive = inclusive ÷ (1 + rate/100), tax = inclusive − exclusive. Intra-state splits the tax 50/50 into CGST and SGST. Inter-state uses the full rate as IGST.
Common GST slabs in India
5% (essentials), 12% and 18% (most goods and services), 28% (luxury / sin goods). Some items also attract cess — this calculator does not add cess.
