Estimated Savings
Got Questions on EV?
1. What is an EV savings calculator?
An EV savings calculator estimates the difference between the running cost of an electric vehicle and a petrol or diesel vehicle using inputs such as driving distance, vehicle efficiency, fuel price and electricity or charging cost.
2. How can I calculate EV savings in India?
Enter your driving distance, petrol or diesel mileage, fuel price, EV efficiency and applicable electricity or charging cost. The calculator can use these values to estimate conventional fuel costs, EV running costs and potential savings.
3. How is EV running cost per km calculated?
EV running cost per kilometre can be estimated using the vehicle's energy efficiency and electricity or charging tariff. For an efficiency expressed in km/kWh, divide the applicable ₹/kWh rate by the vehicle's km/kWh efficiency.
4. How is petrol car running cost per km calculated?
Petrol running cost per kilometre can be estimated by dividing the petrol price per litre by the vehicle's mileage in kilometres per litre. Actual running cost varies with fuel price, mileage and driving conditions.
5. Is an EV cheaper to run than a petrol car?
Running-cost comparisons depend on the specific vehicles, fuel price, electricity or charging tariff, efficiency, driving distance and charging pattern. Use the calculator with your actual inputs rather than relying on a universal savings figure.
6. How much does it cost to charge an electric car in India?
EV charging cost varies according to the energy consumed and applicable electricity or charging tariff. Home, workplace and public charging can have different pricing structures, so the relevant rate should be used for the calculation.
7. What affects EV savings the most?
Major factors include monthly driving distance, petrol or diesel price, ICE vehicle mileage, EV efficiency and electricity or public charging tariff. Changes in any of these variables can significantly affect estimated savings.
8. Does the EV savings calculator include public charging costs?
It can estimate public charging costs when the applicable public charging tariff is entered as the electricity or charging cost. If you primarily charge at home, use the relevant home electricity rate instead.
9. Can I calculate monthly and yearly EV savings?
Yes. Once the estimated cost per kilometre and driving distance are known, monthly running costs can be compared and the difference can be used to estimate potential monthly and annual savings.
10. Are EV savings calculator results exact?
No. Calculator results are estimates based on the values entered. Actual costs can vary because of charging losses, driving style, traffic, weather, vehicle efficiency, fuel prices, charging tariffs and other operating conditions.
