🇮🇳 Fuel & Efficiency Calculator
EV vs Petrol Savings Calculator
Calculate how much you save annually switching to an electric vehicle, and how many years until the EV price premium pays for itself.
⛽ Your Petrol Car
⚡ Electric Vehicle
Tata Nexon EV: ~6-7 · MG Comet: ~8 · Larger SUVs: ~4-5
Representative home rate: ₹7-8/kWh, varies by state and slab. Public fast charging: ₹12-20+.

Electric vs petrol: the real cost picture.
Switching to electric almost always lowers your cost per kilometre - the question is by how much, and how long it takes to offset the higher purchase price. This calculator compares annual fuel cost head-to-head and tells you the breakeven point, but the full picture also includes maintenance, GST savings, and where you plug in.
Where you charge changes everything
Home charging overnight is the cheapest energy most drivers will ever buy - typically ₹6-9/kWh depending on your state and consumption slab. India's public fast-charging network is growing but still costs more per unit, often ₹12-20/kWh. If you can't charge at home, run the calculator with a realistic public rate before assuming an EV will save you money.
Beyond fuel: maintenance and GST
EVs have no oil changes, no spark plugs, and regenerative braking that makes pads last longer. On top of running-cost savings, EVs attract only 5% GST versus 28%+cess on petrol/diesel cars - use the EV Tax/GST Savings calculator to see that number for your specific vehicle.
Frequently asked questions.
How much cheaper is it to charge an EV vs fill up with petrol in India?
At representative rates (₹7.5/kWh home electricity, ₹96/litre petrol), an EV doing 6 km/kWh costs about ₹1.25/km vs roughly ₹6.40/km for a 15 km/l petrol car - a large per-km saving. Home charging tariffs vary a lot by state and slab, so check your own electricity bill for the most accurate number.
What is India's EV incentive if there's no federal tax credit?
India taxes EVs at a much lower GST rate (5%) than petrol/diesel cars (28% GST plus a cess that can push the effective rate to 43-50%). Some states add further road-tax or registration waivers. See the EV Tax/GST Savings calculator for the details.
Do EVs cost more to maintain in India?
Generally yes, less maintenance - no oil changes, fewer brake replacements thanks to regenerative braking, and a simpler drivetrain. Actual savings vary by model and service network, since EV service centers are less widespread than petrol/diesel ones in many cities.
How many years until an EV pays for itself?
It depends on how much you drive, your electricity rate, and the upfront price premium. A high-mileage driver charging cheaply at home can break even in a few years; a low-mileage driver relying on pricier public charging might take much longer. Use the breakeven figure above with your own numbers.
Does home charging really cost less than public charging in India?
Yes, though the gap is narrower than in the US. Home electricity in India often runs ₹6-9/kWh depending on state and consumption slab, while public/DC fast charging can run ₹12-20/kWh or more. The EV cost advantage assumes most of your charging happens at home overnight.
What about battery replacement and resale value?
Most Indian EV batteries carry an 8-year warranty and retain the bulk of their capacity well beyond that, so most owners never replace one during typical ownership. Resale values for EVs in India are still maturing as the used-EV market is relatively young.
