How to Calculate EV Running Cost Per KM in India
The EV running cost per km calculator uses a simple formula. You divide your electricity rate (₹/kWh) by your vehicle's efficiency (km/kWh). For example, if you pay ₹8 per unit of electricity and your electric scooter gives you 35 km per kWh, your running cost is just ₹0.23 per km. A petrol scooter at ₹105 per litre with 45 km/l mileage costs ₹2.33/km. That's an 85% reduction in fuel cost.
For electric cars like the Tata Nexon EV, efficiency is around 7 to 8 km/kWh. At ₹8/kWh, that works out to roughly ₹1.00 to ₹1.14 per km. That's still way cheaper than petrol cars which average about ₹7/km. Our electric vehicle vs petrol cost comparison calculator does this math automatically for both vehicle types, so you get instant results in Indian rupees.
Electricity Cost to Charge an EV at Home in India
Home charging is the cheapest way to refuel an EV. In most Indian states, domestic electricity costs ₹5 to ₹10 per kWh (unit). A typical electric scooter with a 3 to 4 kWh battery costs just ₹24 to ₹40 for a full charge, giving you 100 to 140 km of range. That comes out to roughly ₹0.25 to ₹0.35 per km.
For electric cars, a 40 kWh battery pack costs about ₹200 to ₹400 to charge at home, and it gives you 250 to 320 km of range. Public fast-charging stations charge ₹12 to ₹18 per kWh, which makes it 2 to 3 times more expensive than home charging. Our kWh to km mileage calculator converts your electricity rate into a per-km cost so you can compare it directly against petrol prices.
Quick Reference: Home Charging Cost (2026)
Electric Scooter
₹24 to ₹40
per full charge (100 to 140 km)
Electric Car
₹200 to ₹400
per full charge (250 to 320 km)
Public Charging
₹12 to ₹18
per kWh (2 to 3 times home rate)
EV Battery Replacement Cost vs Petrol Savings
Battery replacement is the biggest concern for EV buyers in India, and for good reason. A replacement battery for an electric scooter costs ₹30,000 to ₹50,000 (after 4 to 6 years), while an electric car battery costs ₹2,50,000 to ₹4,00,000 (after 7 to 10 years). These are big costs that most basic EV vs petrol calculators just skip over.
But here's the thing. The fuel savings over the same period are huge. An electric scooter rider covering 30 km a day saves roughly ₹22,000 to ₹25,000 per year on fuel alone. Over 5 years, that adds up to ₹1,10,000 to ₹1,25,000 in savings. That's more than enough to cover the ₹40,000 battery replacement. Our TCO calculator for EVs in India includes battery replacement cost so you see the net savings, not an inflated number.
Electric Scooter vs Petrol Scooter: Which Costs Less?
Two-wheelers are where India's EV revolution is happening fastest. An electric scooter vs petrol scooter cost comparison shows dramatic savings. The Ola S1 Pro costs roughly ₹0.25 per km to run, while a Honda Activa costs ₹2.33 per km at current petrol prices. That's a 9 times difference.
Let's look at some real examples. The Ola S1 Pro vs petrol scooter running cost comparison shows that with 30 km daily usage, the Ola saves about ₹22,700 per year in fuel. The Ather 450X vs petrol scooter TCO is similar. The Ather gets about 30 km per kWh, which means fuel costs under ₹0.30 per km. Compared to the Activa's ₹2.33 per km, the EV breaks even in 12 to 18 months for most riders.
Our calculator has a "Scooter" preset with real Indian values. You can switch to it and enter your exact daily distance to get a personalized Activa vs EV cost comparison.
EV vs Petrol vs CNG vs Diesel: The Full Running Cost Comparison
In India, the choice isn't just EV vs petrol. Many buyers, especially in cities like Delhi, Mumbai, and Ahmedabad, also look at CNG vs electric car running cost. Here's how all four fuel types compare on a per-km basis (2026 estimates):
| Fuel Type | Cost/km (Car) | Annual Fuel Cost* |
| Electric (EV) | ₹1.00 to ₹1.50 | ₹14,600 to ₹21,900 |
| CNG | ₹2.50 to ₹3.50 | ₹36,500 to ₹51,100 |
| Diesel | ₹4.00 to ₹5.50 | ₹58,400 to ₹80,300 |
| Petrol | ₹6.00 to ₹8.00 | ₹87,600 to ₹1,16,800 |
*Based on 40 km/day driving. CNG at ₹85/kg, Diesel at ₹92/L, Petrol at ₹105/L. EV at ₹8/kWh home charging.
Even CNG, which many people think is the cheapest fuel, costs 2 to 3 times more per km than an EV. The EV vs diesel cost comparison in India is even more dramatic for commercial vehicles. A Nexon EV vs Nexon Petrol cost comparison shows the EV saving ₹60,000 to ₹80,000 per year in fuel alone.
Is an EV Worth It for Commercial Fleets in India?
Commercial vehicles cover a lot more ground every day. Delivery fleets typically do 80 to 150 km, and auto-rickshaws cover 100 to 200 km. This makes the commercial EV vs petrol ROI even more impressive. A last-mile delivery EV vs petrol comparison shows the EV saving ₹1.5 to ₹3 lakhs per year per vehicle in fuel costs alone.
Electric loaders vs diesel auto cost comparisons are just as dramatic. An electric three-wheeler (e-rickshaw) costs ₹0.40 to ₹0.60 per km to run, while a diesel auto costs ₹4 to ₹6 per km. If a fleet of 10 vehicles each covers 100 km a day, switching to EVs saves ₹12 to ₹18 lakhs per year. Our delivery fleet petrol to EV savings calculator factors in higher daily distances so fleet operators can see their real ROI.
Petrol Price vs EV Charging Rate: The 2026 Math
As of 2026, petrol prices in India range from ₹95 (Jaipur) to ₹110 (Mumbai) per litre, while home electricity costs ₹5 to ₹10 per kWh. With our petrol price vs EV charging rate calculator, you can enter your city-specific prices and see exactly how much you save. The electric vs petrol savings in rupees depends on three things: your electricity rate, your petrol price, and how far you drive every day.
The gap gets bigger every year. Petrol prices have historically gone up 5 to 8% per year, while electricity rates rise much slower at just 1 to 3%. Even if petrol drops to ₹85 per litre, an EV still costs 3 to 5 times less per km to run. Our calculator lets you adjust all these numbers so you get the most accurate EV vs ICE vehicle cost comparison for your situation.
