EV vs Petrol Running Cost Comparison in India

Electric cars can have lower energy costs per kilometre than petrol cars, particularly when owners charge at home. However, the difference depends on the vehicle’s efficiency, electricity tariff, petrol price and charging method.

Consider this illustrative comparison using recorded Delhi fuel prices and assumed vehicle efficiencies. The Petroleum Planning and Analysis Cell (PPAC), Government of India, listed retail selling prices from an IndianOil outlet in Delhi on 9 October 2026 at ₹102.12 per litre for petrol and ₹95.20 per litre for diesel. These are dated Delhi examples, not guaranteed prices for every city or fuel station. For the EV, this example assumes electricity costs ₹8 per unit and the car consumes 15 kWh per 100 km. The petrol car is assumed to deliver 15 km per litre, while the diesel car is assumed to deliver 20 km per litre.

Example: Cost Per Kilometre

Source for Delhi fuel-price examples: PPAC, Government of India. Vehicle efficiency and home electricity price are illustrative assumptions. The calculations exclude charging losses, maintenance, insurance, finance costs and vehicle purchase prices.

Under these assumptions, the EV’s estimated energy cost is about ₹5.61 less per kilometre than the petrol car. At 15,000 km per year, that represents a potential difference of approximately ₹84,120 in annual energy expenses if the same prices and efficiencies continue. This is not a guaranteed saving or a complete ownership-cost comparison. Your result could be different if your petrol car has better mileage, your EV consumes more electricity, you depend on public fast charging or fuel and electricity prices change.

Comparing monthly running costs is useful for understanding your regular expenses. For a specific journey, use the EV Trip Cost Calculator to estimate charging expenses based on your trip distance, electricity consumption and charging rate.

How Does the EV vs Petrol Cost Calculator Work?

The calculator compares how much you spend on electricity or fuel to cover the same distance. It then multiplies the estimated cost per kilometre by your driving distance.

EV cost per kilometre

EV cost per km = EV energy consumption (kWh per 100 km) × electricity price per kWh ÷ 100
For example, an EV that consumes 15 kWh per 100 km at ₹8 per unit has an estimated energy cost of ₹1.20 per kilometre before charging losses and additional charging fees.

Petrol cost per kilometre

Petrol cost per km = Petrol price per litre ÷ petrol mileage in km per litre
At ₹102.12 per litre and 15 km per litre, the estimated petrol cost is approximately ₹6.81 per kilometre.

Diesel cost per kilometre

Diesel cost per km = Diesel price per litre ÷ diesel mileage in km per litre
At ₹95.20 per litre and 20 km per litre, the estimated diesel cost is ₹4.76 per kilometre.

Running cost and estimated savings

Cost for a period = Cost per km × Distance driven during that period

Potential EV savings = Petrol or diesel running cost − EV running cost

A positive result means the EV has a lower estimated energy cost under the inputs you supplied. A negative result means the EV’s estimated energy cost is higher under those assumptions. If your EV’s dashboard consumption does not include the electricity lost during charging, the amount drawn from the supply may be higher than the energy used by the vehicle. Use charging-bill data where possible, and do not add a charging-loss allowance twice if your calculator already accounts for it.

How Much Does an EV Cost Per Kilometre in India?

The cost of driving an EV depends on how efficiently it uses electricity and what you pay to charge it. Home charging and public fast charging can have very different prices.

For example, at an assumed consumption of 15 kWh per 100 km:

The public charging example uses ChargeDekho’s price snapshot dated 18 September 2026. It reported a median listed DC fast-charging price of ₹17.99 per kWh across 5,776 entries with published prices. This is a median for the listed chargers included in that dataset, not a fixed national tariff or the price of every public charger.

At the same assumed vehicle efficiency, the public charging example increases energy costs to approximately ₹2.70 per kilometre before any additional fees or charging losses. Your local station may charge more or less, so check its actual rate before using the calculator. Your EV’s energy efficiency directly affects its charging expenses. Use the EV Mileage Calculator to understand how electricity consumption influences the cost of driving your electric car.

Why Does Your City Affect EV and Petrol Running Costs?

The price you pay for energy depends on where and how you refuel or charge. Petrol and diesel prices may vary by city and fuel outlet. Household electricity bills depend on the local electricity provider, tariff category and usage slab. Public charging prices can also vary by network, charger type, location and applicable fees.

For example, a driver who can regularly charge at home may have a different EV running cost from someone who relies on paid DC fast chargers. Apartment residents should check whether their parking location supports a suitable charging installation and what their applicable electricity rate would be.

To keep your calculation useful:

• Use your local petrol or diesel price rather than a price from another city.
• Check the electricity tariff that applies to your charging setup.
• Use the actual public charger price when planning for public charging.
• Update your assumptions whenever fuel prices, tariffs or your driving patterns change.

You can check indicative petrol and diesel prices using IndianOil’s official price information. The company notes that prices may vary between outlets within a city.

Key Advantages of Electric Cars in India

An EV can offer practical advantages, but the value of each benefit depends on how and where you drive.

• Potentially lower energy expenses: An efficient EV can cost less per kilometre to charge than a petrol car, particularly when home electricity is available at a suitable tariff.
• Less routine powertrain maintenance: EVs do not require conventional engine-oil changes and have fewer moving parts in their powertrain. Regenerative braking can also reduce brake wear. India’s e-AMRIT portal explains these general maintenance differences. Tyres, suspension, air conditioning, brakes and other components still require inspection and servicing.
• Smooth, responsive driving: Electric motors deliver power differently from conventional combustion engines and can provide smooth acceleration in everyday driving.
• No tailpipe exhaust emissions while driving: Battery-electric cars do not emit exhaust gases from a tailpipe during use. However, emissions can still arise from electricity generation, vehicle manufacturing and battery production, so this should not be interpreted as zero lifecycle emissions.

Before buying, review the vehicle’s real-world range, charging access, battery warranty and service arrangements. A low running cost alone does not determine whether a car is suitable for you.

How Much Could You Save Over Five Years?

Your annual driving distance can make a considerable difference to the energy savings from an EV.

Using the earlier example, the EV costs ₹1.20 per kilometre and the petrol car costs approximately ₹6.81 per kilometre. At 15,000 km per year, the estimated annual energy-cost difference is approximately ₹84,120. Over five years, that would be about ₹4,20,600 if fuel prices, electricity rates and vehicle efficiency remained unchanged.

This is a simplified running-cost estimate, not a five-year ownership forecast. It excludes the difference in vehicle purchase price, loan interest, insurance, maintenance, tyres, charging equipment, battery-related costs and resale value. To assess whether buying an EV makes financial sense, compare these costs over the period you expect to own the vehicle. A car that costs less to run may still have a higher total ownership cost if its purchase price or financing expenses are substantially higher.

What Are the Main Disadvantages of Electric Cars?

EVs are not the best fit for every driver. Consider these factors alongside the potential savings.

• Initial purchase price: A comparable EV may have a higher upfront price than a petrol car. The difference varies by model, variant and available offers.
• Charging access: Drivers without home parking or a suitable charging point may need to depend on public stations. Check access, cost and convenience before purchasing.
• Long-distance planning: Some journeys may require charging stops. Practical range and charging availability depend on the vehicle, route and conditions.
• Real-world range variation: High speed, heavy traffic, gradients, air-conditioning use, weather and battery age can affect energy consumption and range.
• Battery condition and warranty: Battery performance changes over time and depends on use and conditions. Review the exact warranty terms, including any time, distance or battery-health limits.

Before making a decision, compare a vehicle’s purchase cost and practical suitability with its estimated energy savings. Consider how far you drive, where you park, how you charge and how long you plan to keep the car.
