Who uses a GST calculator?

Shoppers checking how much tax is included in a price.
Accountants splitting tax into CGST, SGST or IGST.
Multiply the price by the GST rate and add it on. For ₹1,000 at 18%: GST is ₹180, so the total is ₹1,180.
How do I remove GST from a price that includes it?+
Divide the inclusive price by (1 + rate). For ₹1,180 at 18%: ₹1,180 ÷ 1.18 = ₹1,000 before GST, so the GST is ₹180. Do not simply subtract 18% of ₹1,180.
What is the difference between CGST, SGST and IGST?+
For a sale within the same state, GST is split equally between the centre (CGST) and the state (SGST). For a sale to another state, the whole amount is charged as IGST.
What are the current GST rates?+
After the GST rate rationalisation, most goods and services fall under 5% or 18%. A 40% rate applies to a small list of luxury and sin goods, and special rates such as 3% apply to gold and jewellery. Some items are exempt. Check the latest notification for your product or service.
