Goods and Services Tax (GST) is charged on most goods and services sold in India. Use this calculator to add GST to a price, or to work back from a price that already includes GST.
GST rates after GST 2.0
From 22 September 2025, most items moved into two main slabs, 5% and 18%, with a 40% rate for luxury and sin goods. Gold and jewellery attract 3%, and some rough diamonds and precious stones 0.25%. Many essential items are exempt (0%). The rate that applies depends on the HSN or SAC code of the product or service, so check the exact rate for what you sell.
Examples
- Adding GST: a ₹1,000 service at 18% costs ₹1,180, of which ₹180 is GST (₹90 CGST + ₹90 SGST within a state).
- Removing GST: if ₹1,180 includes 18% GST, the price before GST is ₹1,000. Note that 18% of ₹1,180 is not the GST amount. You must divide by 1.18.
CGST, SGST and IGST
When the seller and buyer are in the same state, GST is split equally between the Centre (CGST) and the state (SGST). For sales between states, the full amount is charged as Integrated GST (IGST).
