GST What-If Calculator

Petrol and diesel are outside GST today — instead they carry central excise + state VAT. If they were brought under GST, what would the pump price be? Pick a city and a GST rate to see.

Today's Mumbai petrol pump price (live): ₹111.21

Under GST 18% (+ 0% cess): ₹75.46 / litre
₹35.75 cheaper than today
Refinery + dealer base₹63.95
GST (18%)₹11.51
Cess (0%)₹0.00
New pump price₹75.46

Replaces today's central excise (₹19.90) + Maharashtra VAT (₹22.24) + cess (₹5.12) = ₹47.26 of tax with GST + cess.

Illustrative only. Real GST adoption would need a constitutional amendment (Article 366(12A)) and states being compensated for lost VAT revenue. Pump price is live; the GST scenario replaces today's excise + VAT + cess with your chosen GST + cess.
