Ex-showroom price is what the car costs at the showroom before state taxes and legal charges. On-road price is what you actually pay to drive it out. For most petrol and diesel cars, the final number lands 10% to 25% above the sticker, so a ₹12 lakh car ends up near ₹14 lakh.

Most of that gap is fixed by law or set by regulators. The rest is where dealers add padding. This guide shows every line, which ones you can push back on, and how to check your own quote in 10 minutes.

The difference between ex-showroom and on-road price at a glance

Ex-showroom price meaning: what's inside the sticker

Three things sit inside it: the cost of building the car and getting it to the dealer, the dealer's margin, and GST. That's why it can differ a little from city to city.

GST changed recently, and it matters. Since 22 September 2025, cars fall into two slabs, 18% for small cars and 40% for larger ones, with no separate compensation cess. Small means petrol, CNG or LPG cars up to 1200cc, or diesel up to 1500cc, and no longer than 4 metres. Electric cars pay 5%.

If a guide still says 28% GST, it's out of date.

What is on-road price? Car on-road price components

On-road price is the ex-showroom price plus everything the law and your dealer add before the car can leave the lot. Some pieces are fixed. Others are yours to argue with.

Why one number moves everything

Road tax, TCS and own-damage insurance all ride on the price of the car. So when the base moves, the whole bill moves.

Think about what happened when GST dropped in September 2025. Own-damage premiums fell along with car prices, but third-party premiums stayed the same. Road tax followed the same logic, because it's a percentage of the price, so a higher GST directly raises it.

Here's the catch for negotiation. Ask whether a discount comes off the invoice or arrives as free accessories. In many states, taxes are worked out on the invoice value, so an invoice discount can shrink your road tax too, while freebies won't. Confirm the rule for your state with the dealer.

Road tax on new cars and RTO registration charges

Road tax is a one-time state levy on a private car. It's paid once and covers the car for 15 years. It's the biggest single piece of the gap, and it depends on where you live.

Most states charge between 7% and 14% of the ex-showroom price, while Gujarat sits lower at about 6% of the price before GST. The same car can cost very different amounts. On an ₹8 lakh petrol car, one tracker puts total RTO costs at about ₹38,000 in Gujarat and about ₹1,27,000 in Karnataka.

Fuel matters as well. Some states, including Maharashtra and Karnataka, add a 2% surcharge on diesel cars. Electric cars usually pay little or no road tax, but four states rewrote their EV tax rules in 2026 alone, so check your state before you assume.

Registration itself is cheap. Expect about ₹600 for the registration fee, ₹230 to ₹400 for HSRP plates, ₹500 to ₹600 for FASTag, and ₹1,500 for the loan entry if you're financing.

Don't try to save money by registering in a cheaper state. A car must be registered in the state where you live, and one kept from another state for over 12 months has to be re-registered and taxed in yours. Check your state's rate on its transport department site or Parivahan, and ask the dealer for the RTO receipts.

Car insurance cost for a new car

Why does insurance look so heavy on a new-car quote? Because you're paying for more than one year. The bundled policy gives three years of third-party cover and one year of own-damage cover.

The third-party part is fixed. IRDAI sets it at ₹2,094 a year up to 1000cc, ₹3,416 from 1001cc to 1500cc, and ₹7,897 above 1500cc, plus 18% GST. Electric cars get a 15% discount. You can't bargain on that piece. What you can compare across insurers is the own-damage premium and the cashless garage network.

Own-damage cost depends on your IDV, the value your insurer agrees to pay if the car is stolen or totalled, and on add-ons like zero depreciation cover. So compare like for like. Ask the dealer for the premium breakup, then get an outside quote with the same IDV and add-ons. You're free to buy from any insurer.

TCS on luxury cars (and every car above ₹10 lakh)

If the sale value crosses ₹10 lakh, the dealer collects 1% TCS. It isn't only for luxury cars. The threshold applies per vehicle and covers all motor vehicles. From 1 April 2026 the rule sits in Section 394 of the Income-tax Act, 2025, at the same 1% rate. It's worked out on the ex-showroom price including GST.

So is it a cost? Not really. It works as a tax credit that reduces your income tax or comes back as a refund. But it's cash out on day one. On a ₹30 lakh car, that's ₹30,000 you need in hand.

Ask for the certificate. The old Form 27D is now called Form 133. Then check that the amount shows up in your Form 26AS before you file your return.

Hidden costs when buying a car

A good new car buying guide should also cover the charges that don't appear in the advertised price. These are the lines that make quotes swell. Every one of them is worth a question.

• Insurance markup: Match the dealer's premium against your own quote. The gap can be five figures.
• Accessory kits: Mats, mudflaps and seat covers are often priced well above the open market. Check online prices before you nod.
• Extended warranty: Worth it if you'll keep the car past five years or drive a lot. Compare the dealer's price with the carmaker's own. We break down when an extended warranty pays off in a separate guide.
• Paint protection and anti-rust packages: Ask for the product name, brand and a written warranty. If they can't show it, skip it.
• Handling or "processing" fees: Ask why it isn't already in the ex-showroom price.
• Fancy numbers: Optional. If a dealer says a special number is compulsory, push back.
• Prepaid service packs: Compare with what pay-as-you-go servicing would cost you.

Timing helps too. Dealers chase targets at month-end, quarter-end and year-end, so freebies and cash discounts come easier then. Keep an eye on monthly car discounts and plan around them.

On-road price calculator: do it yourself in 10 minutes

On-road price = Ex-showroom + Road tax + Registration, plates and FASTag + TCS (if above ₹10 lakh) + Insurance + Extras you choose

1. Get the ex-showroom price for your exact variant and city from the brand's website.
2. Multiply by your state's road tax rate. In Gujarat, use the price before GST.
3. Add about ₹4,000 for registration, plates and FASTag, and ₹1,500 more if you're taking a loan.
4. Add 1% TCS if the car is above ₹10 lakh.
5. Get an online quote for three-year third-party plus one-year own damage. To estimate, take three times the IRDAI third-party rate, add roughly 2% to 3% of the ex-showroom price for own damage, then add 18% GST.

Stop here. That number is your Legal Floor: the least you can pay to drive the car out. Anything a dealer adds above it is extra.

Here's a worked example for a ₹12 lakh car. We assumed a 12% road tax, so swap in your own state's rate.

That's 17.3% above the sticker. The insurance figure uses ₹3,416 a year for three years of third-party cover and own damage at 2.5% of ex-showroom, plus 18% GST. Your actual quote will differ.

The Wheels42 Padding Score

Now you can measure a dealer quote instead of guessing. Take the dealer's total, subtract your Legal Floor, and divide by the floor. That's your padding percentage.

Say the dealer quotes the same car like this:

Dealer total: ₹14,76,500. Padding: 4.9%.

Here's how we read the score. It's our own rule of thumb, not an industry standard.

Now cut. Buy insurance outside, drop paint protection and handling, negotiate the kit to ₹12,000, and skip the warranty for now. The new total is ₹14,19,493, which saves about ₹57,000 and drops padding below 1%.

Five price cliffs that can flip a cheaper car into a pricier one

A lower sticker doesn't always mean a lower bill. Watch for these lines.

1. The ₹10 lakh TCS line. A ₹9.99 lakh car pays no TCS. A ₹10.01 lakh car pays ₹10,010 on delivery day.
2. The GST small-car line. A compact SUV with a 1500cc petrol engine falls into the 40% slab, while most sub-4-metre rivals stay at 18%. Cross the engine or length limit and the tax jumps.
3. The road tax band. Road tax is a percentage and often rises with price, so a variant that's ₹40,000 dearer can cost noticeably more once tax lands on top.
4. The engine-size line in insurance. Third-party premium goes from ₹3,416 to ₹7,897 a year once you pass 1500cc.
5. The powertrain line. Electric cars get 5% GST, a 15% third-party discount, and often no road tax, while diesel can carry a 2% surcharge in some states. Our EV vs petrol running cost guide runs the per-km numbers.

Why your EMI cares about on-road price

Lenders fund against the on-road number. They generally finance about 90% of it, so padding doesn't just cost you today. It goes into your loan.

Take a 9% rate over five years (an assumed rate). Every ₹1 lakh borrowed costs about ₹2,076 a month. On our example car, the EMI is about ₹26,300 on the Legal Floor and ₹27,600 on the padded quote. A ₹22,000 accessory kit financed the same way ends up costing about ₹27,000.

So run your car loan EMI on the on-road price, never the sticker. The 20/4/10 rule is a handy check: 20% down, a loan of no more than four years, and total car costs under 10% of your monthly income.

Compare two cars on on-road price, not sticker: the Wheels42 Two-Car Scorecard

Stuck between two cars? Don't compare two similar cars by ex-showroom price alone. Score both on the same ten lines. Each line gets 0 to 10 points, multiplied by its weight, and the maximum is 100.

A gap under 5 points is a tie, so let the test drive decide.

Delivery-day checklist

1. The invoice matches your itemised quote, line by line.
2. You have the road tax receipt and the registration application copy.
3. The insurance policy shows your chosen IDV and add-ons.
4. For cars above ₹10 lakh, you have the TCS certificate (Form 133).
5. You know when HSRP plates and FASTag will be fitted.
6. The loan entry is noted if you're financing.
7. You have it in writing which price applies, the booking date or the delivery date.

FAQs

Can I pay only the ex-showroom price and skip the rest?

No. Road tax, registration and insurance are needed to drive legally.

Does the dealer decide my insurance?

No. You can buy from any insurer. Just compare the same IDV and add-ons.

Is the on-road price the same at every dealer?

The ex-showroom price is usually the same within a city. The on-road price differs because of insurance and extras.

Does the same logic work for bikes?

Yes. Small bikes pay 18% GST and bigger ones (around 350cc and above) pay 40%. Road tax and insurance differ, so see our bike on-road price guide.

Can I register in a cheaper state?

Not unless you live there. It has to be your home state.

Ask for the itemised quote, build your Legal Floor, then negotiate only the gap.
