Will Switching to an EV Actually Save You Money?
Running costs are only part of the answer. This compares the full picture — purchase price, fuel, maintenance and resale — so you can see whether the savings really recover the higher upfront cost.

EV vs Petrol in India — What Actually Decides It
The headline case for electric cars in India is real: charged at home, an EV costs roughly ₹1 to ₹1.40 per kilometre against about ₹7 per kilometre for an equivalent petrol car. At 12,000–15,000 km a year, that alone is ₹60,000–1,00,000 saved annually. What the headline usually omits is that you paid ₹4–5 lakh more to buy the car, and you will probably get less of it back when you sell.
The two questions that decide the answer
First, how much do you drive? Savings accrue per kilometre, so the upfront premium is recovered by distance, not by time. A buyer covering 20,000 km a year reaches breakeven far sooner than one covering 6,000.
Second, can you charge where you park? Home charging at ₹6–10 per kWh is what produces the dramatic savings. Public DC fast charging at ₹18–25 per kWh still beats petrol, but it roughly triples your per-kilometre cost and pushes breakeven much further out. If you have no home charging option, the economics change from compelling to marginal.
Why resale value complicates it
An internal-combustion car's used value is reasonably predictable from age and odometer. An EV's value depends heavily on battery State of Health, and India has no universally accepted way to certify that yet. The result is that used EV pricing is soft and cautious: where a petrol car might retain 55–65% of its value after three years, an EV typically retains 40–55%. That gap is a real cost, and it partially offsets the fuel savings.
The battery question, in proportion
Out-of-warranty battery replacement is expensive — roughly ₹4–12 lakh, or 30–40% of the vehicle price. It is also uncommon within a typical ownership period: major manufacturers warrant packs for 8 years or 1,60,000 km, and real-world useful life is generally 10–12 years with 70–80% capacity retained. The honest framing is a low-probability, high-cost risk rather than a scheduled expense — which is why this calculator does not add it to the running total, and instead flags it separately.
