"EVs are cheaper to run" is repeated so often it has become background noise. But how much cheaper, really — and does it offset the higher sticker price? Let's put actual numbers to it, so you can decide based on your own driving rather than a slogan.
The per-kilometre maths
Petrol car: a typical car doing ~15 km per litre, with petrol around ₹100/litre, costs roughly ₹6.7 per km in fuel. A less efficient car or city driving pushes that higher.
Electric car: a typical EV uses about 6 km per kWh (i.e. ~15–16 kWh/100 km). Charged at home at ~₹8/unit that's about ₹1.3–1.5 per km. On public fast chargers at ₹18–24/kWh it's more like ₹3–4 per km — still below petrol, but the gap narrows sharply.
So the headline is true: home-charged, an EV can cost a fifth of a petrol car per km. The catch is that the saving depends heavily on where you charge.
Beyond fuel: maintenance and other costs
- Maintenance: EVs have far fewer moving parts — no engine oil, spark plugs, timing belts or clutch. Servicing is genuinely cheaper over time.
- Upfront price: EVs still cost more to buy than an equivalent petrol car, though central and state incentives narrow the gap (these vary by state and change — check your state's current EV policy).
- Battery & resale: batteries are warrantied for years/lakhs of km, but long-term battery health and resale value are still maturing in India — factor them in for a long hold.
- Charging time & access: a home charge point transforms the economics; without one, you rely on public networks that cost more and need planning.
Working out your own break-even
The switch pays off faster the more you drive and the more you can charge at home. A rough approach:
- Estimate your annual km.
- Multiply by the per-km saving (petrol ₹6.7 − home-EV ₹1.4 ≈ ₹5.3/km if you charge at home).
- Add typical maintenance savings per year.
- Divide the EV's price premium by that annual saving to get the break-even in years.
For a high-mileage driver who charges at home, break-even often lands within a few years — comfortably inside typical ownership. For a low-mileage driver dependent on public charging, it can stretch out, and a fuel-efficient petrol (or CNG) car may still make more sense.
Planning EV trips
Range anxiety fades once you plan. For long drives, know where chargers sit along your route and how many stops you'll need — the Road Trip Planner shows charging stations along the corridor and estimates charging stops, and you can browse stations on the EV charging directory.
Frequently asked questions
Is an EV really cheaper to run than petrol? Yes, especially charged at home — often around a fifth of the per-km fuel cost. Public fast charging costs more but is usually still cheaper than petrol.
What's the biggest factor in EV savings? Home charging. Without it, savings shrink considerably.
Does an EV make sense for low annual mileage? The upfront premium takes longer to recover; a fuel-efficient petrol or CNG car may be more economical.
