Ex-showroom price is the price of a car at the dealership before it is registered for road use. In India it includes the factory cost, dealer margin and GST with compensation cess, but excludes road tax, registration charges, insurance and TCS. It is the headline price manufacturers advertise, and the base on which most other charges are calculated.
What it includes — and what it doesn't
The ex-showroom price bundles the ex-factory cost, transportation to the dealer, dealer margin and all central taxes (GST plus cess, which together range from about 29% to 50% depending on the car's size and engine). It does not include state road tax, RTO registration fees, insurance premium, TCS, FASTag or accessories — which is why the amount you actually pay is always higher. That full figure is the on-road price.
Why it matters when buying
Almost every other charge on your invoice is a percentage of the ex-showroom price. Road tax is typically 4–20% of it depending on your state, first-year insurance is quoted against it, and the 1% TCS applies when it crosses ₹10 lakh. So a small difference in ex-showroom price compounds: choosing a variant that is ₹50,000 cheaper ex-showroom can save you ₹60,000–65,000 on-road.
A concrete example
Take a car with an ex-showroom price of ₹10 lakh in a state with 10% road tax. You'd pay roughly ₹1 lakh as road tax, ₹40,000–50,000 for insurance, plus registration and handling — landing near ₹11.5 lakh on-road. The ₹10 lakh you saw in the ad is the starting point, not the final bill.
