| Rate | Examples (not a complete list) |
|---|---|

GST formulas
- Add GST: GST = price × rate ÷ 100, total = price + GST. Example: ₹1,000 at 18% gives ₹180 GST and ₹1,180 total.
- Remove GST: price before GST = total × 100 ÷ (100 + rate). Example: ₹1,180 including 18% gives ₹1,000 before GST and ₹180 GST.
- Within a state, GST is split equally into CGST and SGST (or UTGST). Between states, the full amount is IGST.

Frequently asked questions
What are the new GST rates in 2026?
Since 22 September 2025 the main GST slabs are 5% and 18%. A special 40% rate applies to luxury and harmful goods such as pan masala, sugary drinks and large cars. Gold and silver are at 3%, rough diamonds at 0.25%, and many essentials such as fresh milk, paneer and individual health insurance are exempt.
How do I calculate GST from an inclusive price?
Choose "Remove GST", type the price that already includes GST and pick the rate. The tool divides by (100 + rate) and multiplies by 100 to find the price before tax; the difference is the GST. For ₹1,180 at 18%, that is ₹1,000 plus ₹180 GST. The Reverse GST Calculator does only this.
What is the difference between CGST, SGST and IGST?
For a sale within one state, GST is split equally: half goes to the centre as CGST and half to the state as SGST (UTGST in union territories). For a sale to another state, the whole amount is charged as IGST by the centre. The total tax is the same either way.
Is 12% GST removed?
For most items, yes. In GST 2.0, most goods that were at 12% moved to 5%, and most at 28% moved to 18%. A few items and transitional cases remain different, and invoices dated before 22 September 2025 still show the old rates, which you can enter with "Other".
What is the 40% GST rate for?
The 40% rate is for "sin" and luxury goods: pan masala, aerated and caffeinated sugary drinks, cars above the small-car limits, motorcycles above 350cc, yachts, private aircraft and some similar items. It replaced the earlier 28% rate plus compensation cess for these goods.
How do I add 18% GST to a price?
Multiply the price by 0.18 to get the GST and add it: ₹2,500 × 18% = ₹450, so the total is ₹2,950. In this calculator, choose "Add GST", type 2500 and pick 18%. Within the state that is ₹225 CGST and ₹225 SGST.
