Frequently asked questions
How do I add GST to a price?+
GST amount = price × rate ÷ 100, and total = price + GST. To remove GST from an inclusive price, GST = price × rate ÷ (100 + rate).
What is CGST and SGST?+
For intra-state sales, GST splits equally into CGST (central) and SGST (state). An 18% rate becomes 9% CGST + 9% SGST.
