How GST is calculated
- GST excluding: GST = amount x rate / 100; total = amount + GST.
- GST including: base = total / (1 + rate / 100); GST = total – base.
- Within one state GST splits equally into CGST and SGST; across states it is charged as IGST.
Rates change by notification, so confirm the rate for your HSN/SAC code with your CA.
FAQ
How do I calculate GST on an amount?
Multiply the price by the GST rate and divide by 100. For GST-inclusive prices, divide the total by (1 + rate/100) to get the base value.
What is the difference between CGST, SGST and IGST?
For a sale within the same state, GST is split equally into CGST and SGST. For a sale to another state, the full GST is charged as IGST.
Which GST rate should I use?
Use the rate that applies to your item’s HSN or SAC code as per the latest GST notification. Confirm with your CA if unsure.
