Question 1

How accurate is this EV vs petrol calculator?

Accepted Answer

We use real 2026 Indian prices for petrol, electricity, vehicle mileage, and maintenance. The defaults are based on average Indian conditions. You can change every number to match your city, so the result is as close to your real life as possible.

Question 2

Does this EV savings calculator include battery replacement cost?

Accepted Answer

Yes! Many basic calculators skip this. We let you set when the battery needs replacement (anywhere from 3 to 10 years) and how much it costs. Even after adding battery replacement, EVs usually come out cheaper over 5 to 7 years of ownership.

Question 3

What is Total Cost of Ownership (TCO)?

Accepted Answer

TCO means the total amount you spend on a vehicle over the years. It's not just the price tag. It includes the purchase price, fuel or electricity cost, yearly maintenance, and battery replacement for EVs. Our total cost of ownership calculator for EVs gives you this full picture instead of just comparing per-km cost.

Question 4

Why is an EV so much cheaper to run than a petrol vehicle?

Accepted Answer

Electric motors use energy much more efficiently. They're about 3 to 4 times better than petrol engines. For example, a typical electric scooter costs around ₹0.30 to ₹0.50 per km, while a petrol scooter costs ₹2 to ₹3 per km. EVs also have fewer parts that wear out, so maintenance is cheaper too.

Question 5

What electricity rate should I enter in the electric car running cost calculator?

Accepted Answer

Use the rate you pay at home. In most Indian states, home electricity is ₹5 to ₹10 per kWh (unit). If you charge at a public station, it's usually ₹12 to ₹18 per kWh. The default is ₹8/kWh, which is a typical home rate.

Question 6

Can I use this EV vs gas calculator outside India?

Accepted Answer

The defaults are set for India (rupee currency, Indian fuel and electricity prices). But you can change every input. Prices, mileage, the currency doesn't matter for the math. So yes, it works anywhere. Just update the numbers to match your country.

Question 7

Are there government subsidies for EVs in India?

Accepted Answer

Yes. EVs have a lower 5% GST compared to 28% for petrol vehicles, and many states like Delhi, Maharashtra, and Gujarat offer extra discounts. There are also income tax benefits under Section 80EEB. Our calculator does not include these subsidies, so your actual savings might be even higher than what we show.

Question 8

Is my data safe? Do you store anything?

Accepted Answer

We do not store any of your data. All calculations happen directly inside your web browser. We never ask for your name, email, or phone number, and there are no ads or tracking scripts. It is completely private.

Question 9

How do you calculate EV running cost per km in India?

Accepted Answer

To find the cost, divide your electricity rate by how many kilometers your vehicle gets per unit. For example, if you pay ₹8 per unit and your scooter goes 35 kilometers per unit, your cost is about ₹0.23 per kilometer. Our calculator does this math for you automatically.

Question 10

Is an EV cheaper than CNG in India?

Accepted Answer

Yes. CNG costs around ₹2.50 to ₹3.50 per km for a car, while an EV costs ₹1.00 to ₹1.50 per km on home charging. That's roughly 2 to 3 times cheaper. CNG also requires periodic tank certification and has limited refueling stations outside major cities. An EV vs CNG vs petrol comparison clearly shows EVs are the cheapest to run in India.

Question 11

How much does it cost to charge an EV at home vs petrol cost?

Accepted Answer

A full home charge for an electric scooter (3 to 4 kWh battery) costs ₹24 to ₹40 at standard residential rates, giving 100 to 140 km range. Filling a petrol scooter for the same range costs ₹210 to ₹330. For electric cars, a full charge costs ₹200 to ₹400 vs ₹1,400 to ₹2,100 for the equivalent petrol fill-up. Home charging is 5 to 7 times cheaper than petrol.

Question 12

Is the Ola S1 Pro cheaper to run than a petrol Activa?

Accepted Answer

Much cheaper. The Ola S1 Pro gives you about 30 to 35 km per kWh, making its running cost about ₹0.23 to ₹0.27 per km. The Honda Activa averages 45 km per litre, costing ₹2.33 per km at ₹105/L petrol. That's a 9 times difference. Over a year of riding 30 km a day, the Ola saves you roughly ₹22,000 to ₹23,000 in fuel alone.

Question 13

What is the total cost of ownership (TCO) of an EV in India?

Accepted Answer

TCO includes purchase price plus fuel or electricity cost plus maintenance plus battery replacement over your ownership period. For a typical electric scooter over 5 years (riding 30 km a day), the TCO is around ₹1,75,000 to ₹2,00,000. A similar petrol scooter's TCO is ₹2,10,000 to ₹2,50,000. The gap is even wider for cars. An EV can save you ₹2 to ₹4 lakhs over 10 years.

Question 14

Are EVs worth it for commercial delivery fleets in India?

Accepted Answer

Absolutely. Commercial vehicles cover 80 to 150 km a day, which makes the per-km savings add up fast. A delivery fleet switching from petrol to EVs can save ₹1.5 to ₹3 lakhs per vehicle per year in fuel costs. Electric three-wheelers cost ₹0.40 to ₹0.60 per km vs ₹4 to ₹6 per km for diesel autos. For a fleet of 10 vehicles, that's ₹12 to ₹18 lakhs saved every year.

Question 15

How does hybrid vs EV vs petrol compare in India?

Accepted Answer

Hybrids fall between EVs and petrol vehicles in running cost. They typically cost ₹3 to ₹5 per km for a car. They're cheaper than pure petrol but still 3 to 5 times more expensive per km than a full EV. Hybrids also don't qualify for EV subsidies or the lower 5% GST rate. For most Indian buyers who drive within city limits (under 100 km a day), a full EV is the better financial choice.

Question 16

What is the break-even km for Nexon EV vs Nexon Petrol?

Accepted Answer

The Tata Nexon EV costs roughly ₹4 to ₹5 lakhs more upfront than the Nexon Petrol. The EV saves about ₹5 to ₹6 per km in running costs (₹1/km vs ₹7/km), so you break even at around 70,000 to 90,000 km. That's typically 4 to 5 years for someone driving 40 to 50 km a day. After break-even, every km driven is pure savings.
