How do I calculate GST on a price?
Multiply the price by the GST rate and divide by 100. GST amount = price × rate ÷ 100. The final price is the price plus the GST amount.
How do I remove GST from a GST-inclusive price?
Divide the inclusive price by (1 + rate ÷ 100) to get the base price. For 18% GST, base price = inclusive price ÷ 1.18. The difference is the GST amount.
What is the difference between CGST, SGST and IGST?
For a sale within the same state, GST is split equally into CGST (central) and SGST (state). For a sale to another state, the full amount is charged as IGST.
