EV Charging Cost Calculator 2026
Exact charging cost, time, and savings vs petrol — in seconds

1. Battery capacity and how much you're topping up

You rarely charge from empty to full. Most daily charging is a top-up — say from 30% to 80% — so the relevant number is the percentage gap, not the full battery size.

2. Charging losses — the energy you pay for but don't store

Some electricity is lost as heat converting AC grid power to DC battery power, and keeping the battery at a safe temperature. Home AC charging loses roughly 8–12%; DC fast charging loses slightly more, around 12–15%.

3. Electricity rate — home vs public vs your state's tariff

This is the single biggest lever. Home charging on a domestic tariff (₹6–₹9/unit, or a discounted EV tariff where available) is dramatically cheaper than public DC fast charging (₹18–₹25/unit), which carries a premium for speed, land, and station overheads.

Home charger installation

A dedicated 7.2 kW AC wall charger typically costs ₹15,000–₹30,000 installed, including any electrical panel upgrades. Not mandatory (you can use a standard socket), but it charges roughly twice as fast with lower losses.

Battery degradation over time

Lithium-ion EV batteries typically retain 70–80% of original capacity after 8–10 years or 1.5–2 lakh km, depending on charging habits and climate. Most manufacturers offer 8-year/1.6 lakh km battery warranties covering excessive degradation.

Tyre wear

EVs are heavier than equivalent petrol cars (due to battery weight) and deliver instant torque, which can wear tyres 10–20% faster. Budget slightly more frequent tyre replacement into running costs.

Insurance premium

EV insurance premiums are sometimes 10–15% higher than petrol equivalents due to battery replacement costs, though this gap is narrowing as EV repair networks mature in India.

A 3 kW rooftop solar system generates roughly 12–15 kWh per day in most Indian cities — enough to cover 80–100 km of typical EV driving range. Since most EV charging happens overnight when solar isn't generating, net metering matters: daytime solar export offsets the electricity you draw back at night to charge.

The PM Surya Ghar Muft Bijli Yojana scheme offers subsidies covering a meaningful share of eligible rooftop solar system costs, which can shorten the payback period for a solar + EV combination considerably compared to solar alone.

PM E-DRIVE Scheme

The PM E-DRIVE (Electric Drive Revolution in Innovative Vehicle Enhancement) scheme, a ₹10,900 crore central initiative that replaced the earlier FAME programmes, sets aside roughly ₹2,000 crore specifically for expanding public charging infrastructure, alongside vehicle purchase incentives for two- and three-wheelers, buses, and ambulances. Operational guidelines released under the scheme define a tiered subsidy: government premises, hospitals, and residential colonies offering free public access can get up to 100% support on upstream infrastructure and equipment, while high-footfall public locations like railway stations, airports, and highway retail outlets typically qualify for 70–80% support.

State EV Policies

Beyond the central scheme, individual states run their own EV policies with capital subsidies for setting up charging stations (commonly in the ₹1–10 lakh per station range depending on charger type and state), mandates for EV-ready parking in new buildings, and in some cases additional purchase incentives layered on top of central benefits.

What This Means for Your Charging Cost

These subsidies mostly target the businesses and government bodies building charging stations, not individual EV owners directly — but more subsidised stations generally means more competition and, over time, more stable public charging prices near you. If you're setting up a charger for a housing society, RWA, or business, it's worth checking current eligibility with your state nodal agency since scheme terms and deadlines are revised periodically.

Expect to rely almost entirely on DC fast charging

On the road, you won't have overnight AC access, so most stops will be at highway DC fast chargers priced ₹18–₹25/unit — roughly double to triple your home rate. A 300 km trip in a Nexon EV-class car might need one or two top-up stops of 20–40 minutes each.

Sample cost: Delhi to Jaipur (~280 km)

A car with a real-world range of around 300 km could complete this largely on one charge, but most drivers top up once en route as a safety margin — typically a 30–40% top-up costing roughly ₹300–₹500 at highway DC rates, plus whatever remains to top back up to full at the destination.

Budgeting rule of thumb

For trip planning, assume your effective cost per km on the highway will be 2–3× your home charging cost per km, purely because you're paying DC fast-charging rates instead of home AC rates — not because the car is less efficient at highway speed (though higher speeds do modestly reduce range too).

A petrol car doing 50 km a day at roughly 12 km/litre burns about 4.2 litres of fuel daily, and each litre of petrol combusted releases roughly 2.3 kg of CO₂ — putting daily tailpipe emissions for that commute at around 9–10 kg of CO₂, or roughly 3.3–3.6 tonnes a year, before accounting for upstream fuel extraction and refining emissions.

An EV shifts that emission point from the tailpipe to the power plant generating the electricity, and how "clean" that is depends on your local grid mix — a home charged mostly off rooftop solar comes close to zero operational emissions, while a grid still heavily reliant on coal will have a smaller, but still meaningful, emissions edge over petrol per km.

Either way, EVs are generally significantly cleaner per km than petrol even on India's current grid mix, and that gap widens every year as more renewable capacity comes online — meaning the environmental case for an EV bought today keeps improving over its lifetime, on top of the running-cost savings already covered above.
