How GST is worked out
To add GST, multiply the amount by the rate. ₹10,000 at 18% is ₹1,800 of GST, so the customer pays ₹11,800.
GST = Amount × Rate ÷ 100 and Amount before GST = Total × 100 ÷ (100 + Rate)
Within your state, GST splits equally into CGST and SGST. For a sale to another state, it is charged as IGST.
Which rate applies to me?
Rates depend on the HSN code of what you sell. Check with your CA when unsure.

Is this calculator up to date with GST rates?
It works with any rate. The quick buttons show the common slabs; type any other rate in Custom.
What is the difference between IGST and CGST + SGST?
CGST + SGST is for sales within your state; IGST for sales to another state. The total is the same.
