GST Calculator
Add GST to a price or take it out of a GST-inclusive price, at the GST 2.0 rates of 5%, 18% and 40%, with the CGST, SGST or IGST split.
How this calculator works
From 22 September 2025, GST 2.0 replaced the 5/12/18/28% structure with two main slabs, 5% and 18%, plus 40% for luxury and sin goods such as aerated drinks and larger cars (tobacco and pan masala moved to 40% on 1 February 2026, when the compensation cess ended). Gold and silver stay at 3% and rough diamonds at 0.25%; many fresh foods and essentials are exempt.
Adding GST: GST = price × rate ÷ 100. Removing GST: price before GST = inclusive price ÷ (1 + rate ÷ 100). Within a state the GST is split equally into CGST and SGST (UTGST in union territories); between states it is charged as IGST.
Worked example: ₹10,000 at 18%
| Item | Amount |
|---|---|
| GST added | ₹1,800 |
| Price including GST | ₹11,800 |
| CGST + SGST | ₹900 + ₹900 |
| Removing 18% from ₹11,800 | ₹10,000 |

Frequently Asked Questions
What are the GST slabs in 2026?
Since 22 September 2025: 5% and 18% as the main rates, 40% for luxury and sin goods, 3% for gold and silver, 0.25% for rough diamonds, and 0% for exempt items.
How do I remove GST from a price?
