The honest answer is: it depends on how much you drive and where you charge — but the running-cost gap is large enough that for most regular drivers, it's worth doing the math before assuming either option is obviously cheaper.
Running cost per km
Charging at home on a typical domestic electricity tariff (₹6-8 per kWh) with average EV efficiency, most electric cars cost roughly ₹0.80-1.15 per km to run. A comparable petrol car typically costs ₹6-7 per km at current fuel prices. That's a real, large gap — but it shrinks a lot if you rely on public DC fast charging, which in India commonly runs ₹18-25 per kWh, pushing your effective cost to ₹3-4 per km.

The GST gap
Since GST 2.0 took effect (22 September 2025), electric vehicles are taxed at a concessional 5% GST, while petrol/diesel cars fall under 18% or 40% depending on size and engine — a difference that, on a ₹15 lakh car, can mean roughly ₹3.45 lakh or more in tax alone. This is on top of whatever state-level incentives apply (see our Punjab EV Policy guide).
Where petrol still wins
- Upfront price: Even with the GST advantage, most EVs still cost more than an equivalent petrol model before incentives, because battery packs remain expensive.
- Refuelling time: A petrol fill-up takes minutes; even fast DC charging takes 20-40+ minutes for a meaningful top-up, and home charging takes hours.
- No home charging access: If you can't charge at home (no dedicated parking, no wiring), you're pushed toward more expensive and less convenient public charging, which erodes the running-cost advantage.
- Long, frequent highway trips: Range anxiety and charging-stop planning are real considerations if most of your driving is long-distance — check our EV Trip Planner before assuming a road trip will be as simple as a petrol car's.
Where the EV wins clearly
If you drive more than roughly 1,000-1,200 km a month, have access to home or workplace charging, and mostly do city/commute driving, the lower running cost compounds fast — commonly cited annual fuel savings are in the ₹85,000-90,000 range for a typical mid-size EV versus its petrol equivalent, which over 5 years adds up to several lakh rupees, often enough to offset the higher purchase price.
The real comparison to make
Don't compare list prices alone — compare total cost of ownership over the years you'll actually keep the car. Our ownership cost calculator factors in depreciation, energy cost, insurance and maintenance together, which is the number that actually decides which option is cheaper for your situation.
