Every assumption is editable, and you can share your exact result with a link.
How this EV vs petrol calculator works
- Running cost — EV electricity cost per km (from battery size, real-world efficiency and your tariff) vs petrol/diesel/CNG fuel cost per km.
- Total cost — running cost plus typical maintenance over your chosen years of ownership.
- Break-even — when the EV’s cumulative savings pay back its higher on-road price versus a comparable petrol car.
Prices and tariffs are indicative defaults for India and fully editable. For reference only, not a quote.
EV vs petrol cost — FAQs
Is an EV really cheaper to run than petrol in India?+−
Usually, yes. At roughly ₹8 per unit of electricity versus about ₹100 per litre of petrol, an electric car’s running cost per kilometre is a fraction of a petrol car’s. This calculator shows your exact yearly saving and how many years it takes to offset an EV’s higher upfront price.
How is the cost of ownership calculated?+−
It compares the per-kilometre energy cost (EV electricity vs petrol, diesel or CNG fuel) plus typical maintenance, across your daily distance and years of ownership, using prices you can edit. Break-even is the point where cumulative running-cost savings offset the EV’s price premium over a comparable petrol car.
Does it compare diesel and CNG as well?+−
Yes. Alongside petrol, the calculator shows diesel and CNG running costs too, so you can compare an EV against whichever fuel you would otherwise buy.
Can I change the electricity tariff and fuel prices?+−
Yes — tap “See 5-year breakdown” to edit the electricity tariff, petrol/diesel/CNG prices, mileage and the EV/petrol price assumptions. Your inputs are saved in the page link, so “Copy link” shares the exact result you see.
