How to Compare an EV and a Petrol Car

Enter your monthly kilometres and how many years you will keep the car. Fill in the price, real mileage and fuel rate of the petrol car, then the price, real range per unit and electricity rate of the EV. Press compare to see running cost per km, monthly saving, break-even time and the total cost over your years.

Is an EV really cheaper than a petrol car?

An EV usually costs less to run, but its purchase price is often higher. The tool adds both so you can see how many years it takes for the running saving to cover the extra price.

How do I find the cost per km of an EV?

Divide the electricity rate by the km you get from one unit. With power at 8 rupees and 6 km per unit, the energy cost is about 1.33 rupees per km.

What is break-even in this tool?

It is the point after which the money saved on running cost is more than the extra amount you paid for the EV, including any battery cost you enter.

Which numbers should I use?

Use your real petrol price, your real mileage (not the company claim), your home electricity rate and how much you charge at public stations. Every field can be changed.

What is not included?

Resale value, insurance, road tax, loan interest and future price changes are not included, so treat the result as a close estimate.

Is an electric car cheaper than a petrol car?

An electric vehicle usually costs less per kilometre to run, but it often costs more to buy. Whether it is the better deal for you depends on how far you drive, how long you keep the vehicle, and what you pay for petrol and electricity. This calculator puts those numbers side by side instead of guessing.

How the cost per km is worked out

Petrol cost per km is the fuel price divided by your real mileage. For example, petrol at 100 rupees a litre and a car that gives 15 km per litre costs about 6.67 rupees per km before service. EV cost per km is the electricity rate divided by the km you get per unit. At 8 rupees per unit and 6 km per unit, that is about 1.33 rupees per km. Service cost per km is then added to both.

Break-even

If the EV costs more to buy, the monthly running saving slowly pays back the difference. The break-even time is the extra price divided by the monthly saving. The more you drive, the sooner it comes. Someone who drives 300 km a month may never reach break-even in a normal ownership period, while someone who drives 2,000 km a month may reach it within a few years.

Tips for using real numbers

  • Use the mileage you actually get in city and highway driving, not the number in the brochure.
  • If you charge at public stations often, raise the public charging share, because those rates are usually much higher than home power.
  • Add a battery replacement cost if you plan to keep the EV for many years and the warranty will end.
  • Remember that resale value, insurance, road tax and loan interest are not in the result, and they can change the final picture.
