EV vs Petrol: What 5 Years of Ownership Really Costs (With Numbers)

The short answer: over five years and 60,000 km, a ₹13 lakh electric compact SUV costs about ₹12.0 lakh to own after you sell it. A comparable ₹10 lakh petrol car costs about ₹12.6 lakh, so the EV saves roughly ₹60,000. That only holds if you drive 10,000+ km a year, charge mostly at home, and skip road tax on the EV. Miss any one of those and petrol wins.

The setup: two comparable cars

Let's compare like with like: a compact SUV, the kind you'd cross-shop at the same showroom.

Petrol in Delhi has climbed to about ₹102 a litre, up nearly 8% in a year, so I rounded to ₹100. Charging rates and road-tax rules come from current sources. The car prices, insurance, servicing and resale figures are my modeling assumptions. Treat them as a template and swap in your own.

The 5-year cost breakdown

(1 lakh = ₹1,00,000)

The EV wins by about ₹60,000. That's a squeaker, not the ₹5 lakh victory some calculators promise.

Where the money actually goes

Here's the useful way to see it: the EV earns ₹3.75 lakh in running-cost savings, then hands ₹3.15 lakh back through higher upfront and ownership costs. The gap between those two numbers is your profit.

Purchase price and road tax

The EV starts ₹3 lakh behind. Everything else is the EV clawing that back.

Road tax is the swing factor. Delhi exempts EVs up to ₹30 lakh, while Uttar Pradesh waives tax only for EVs made in the state, and Karnataka reworked its exemption in April 2026. Rules keep moving. Ask the dealer for a full on-road price breakup before you fall for any EV.

Fuel versus electricity

The petrol car costs about ₹7.14 per km (₹100 ÷ 14). The EV costs about ₹1.73 per km on our blended mix. That's ₹5.41 saved on every kilometre.

Charge only at home and it drops to roughly ₹1.33 per km. Public fast charging is a different story: ₹18–24 per unit including service fees, or about ₹3–4 per km. One more catch: adding an EV can push a household into a higher tariff slab, so your real rate may exceed your old average.

Servicing

No engine oil, no spark plugs, no clutch. As a real-world example, Tata's Punch EV first service ran about ₹4,200 versus ₹8,500 for the petrol Punch.

I left tyres out of both columns on purpose. EVs are heavy and quick off the line, so tyres wear as fast or faster.

Insurance

Premiums follow the car's declared value, so the pricier car costs more to insure. I added ₹0.3 lakh over five years for the EV. Get real quotes, because this line varies by insurer.

Resale and the battery

This is the EV's weak spot. EV resale in India still trails petrol and diesel, with listings showing value drops from 20% to over 50% within one to four years. I assumed the petrol car keeps 50% of its price and the EV keeps about 35%.

On the battery: many makers cover it for around eight years, and a few offer lifetime cover for the first owner, but that cover usually shrinks back to the standard term when you resell. In year five you're safely inside warranty. A used-car buyer will still worry about the pack, and that worry is priced into your resale.

What flips the result

Most calculators use the best-case home tariff and quietly skip resale. Here's what happens when one assumption changes:

That last row surprised me. Extra interest on the ₹3 lakh premium costs roughly ₹60,000, which cancels the base-case saving. Distance, home charging and road tax move the needle more than anything else.

Work out your own break-even in 4 steps

1. Petrol cost per km = price per litre ÷ km per litre.
2. EV cost per km = your blended price per kWh ÷ km per kWh.
3. Extra EV ownership costs = price gap + insurance gap + charger + resale gap − road tax you skip. In our case that's ₹3.15 lakh.
4. Break-even km = (extra costs − maintenance savings) ÷ (petrol cost per km − EV cost per km).

Our numbers: (₹3.15 L − ₹0.5 L) ÷ ₹5.41 ≈ 49,000 km. That's about 10,000 km a year over five years.

Which one should you buy?

An EV makes sense if you:

• Drive 10,000+ km a year, roughly 30 km or more a day
• Can charge at home or at work
• Live where EV road tax is waived
• Plan to keep the car five years or more

Stick with petrol (or look at CNG or a hybrid) if you:

• Drive under 8,000 km a year
• Park on the street with no charging access
• Take long highway trips often, since fast-charging eats the savings
• Might sell within three years, when resale is a gamble

Common mistakes to avoid:

• Comparing a base petrol variant with a loaded EV. Match features, or you'll flatter the petrol car.
• Assuming 100% home charging when you'll really charge 80–90% at home.
• Comparing ex-showroom prices instead of on-road prices.
• Ignoring loan interest on the higher price.

Final takeaway

An EV wins on running costs, not on purchase price. It's the better buy when you drive a lot, charge at home and dodge road tax. Otherwise a petrol car often comes out ahead, and the gap is smaller than the marketing suggests.

Before you decide, plug your own distance, tariff and on-road quote into the four-step formula. Ten minutes of math beats a decade of regret.
