Adding GST: multiply the base amount by the rate and add it. ₹1,000 at 18% = ₹180 GST, so the total is ₹1,180. Removing GST from a GST-inclusive price: divide by (1 + rate). ₹1,180 ÷ 1.18 = ₹1,000 base, meaning ₹180 was GST. This calculator does both instantly and also shows the CGST/SGST or IGST split.
India has five main GST rates: 0% (essentials like fresh milk, vegetables, books), 5% (packaged food, footwear under ₹1,000), 12% (processed food, some appliances), 18% (most goods and services, restaurants, phones) and 28% (cars, ACs, luxury and sin goods, often with an extra cess). Always confirm the exact rate and HSN/SAC code for your specific product before invoicing.
To add GST, multiply the amount by the GST rate and add it: e.g. ₹1,000 at 18% GST = ₹180 GST, total ₹1,180. To remove GST from a GST-inclusive price, divide by (1 + rate): ₹1,180 ÷ 1.18 = ₹1,000 base + ₹180 GST.
For a sale within the same state, GST is split equally into CGST (central) and SGST (state) — so 18% becomes 9% + 9%. For an inter-state sale, the whole GST is charged as IGST (integrated GST) instead.
The main GST rates are 0%, 5%, 12%, 18% and 28%. Essentials are often 0% or 5%, most goods and services are 18%, and luxury or sin goods are 28% (sometimes with an extra cess).
