Charging an EV at home in India typically costs about ₹6 to ₹9 per unit (kWh), while public DC fast charging is commonly quoted at roughly ₹15 to ₹25 per kWh. For a 40 kWh battery, that is about ₹240 to ₹360 at home and about ₹600 to ₹1,000 at a public fast charger. Your exact cost depends on your state tariff, your operator and your car. This guide gives you the formula, realistic ranges and ways to charge for less.
How to calculate your EV charging cost
Cost of one charge = energy added (kWh) × tariff (₹ per kWh)
A "unit" on your electricity bill is one kWh. Because some energy is lost as heat during charging (roughly 5% to 10%), the energy drawn from the meter is a little higher than the energy that reaches the battery.
EV charging cost in India: home vs public
| Where you charge | Typical rate (₹ per kWh) | Full 40 kWh charge (approx.) |
|---|---|---|
| Home (domestic tariff) | ₹6 to ₹9 | ₹240 to ₹360 |
| Public AC charger | ₹10 to ₹18 | ₹400 to ₹720 |
| Public DC fast charger | ₹15 to ₹25 (many near ₹18 to ₹22) | ₹600 to ₹1,000 |
Ranges come from published 2026 guides and differ between sources. They are estimates for budgeting, not guaranteed prices. A 40 kWh example is used for easy comparison; your battery size will differ.
Cost per km (worked example)
This is an illustration, not a promise. Assume a car that uses 15 kWh per 100 km (0.15 kWh per km):
| Charging type | Rate (₹ per kWh) | Cost per km |
|---|---|---|
| Home | ₹6 to ₹9 | ₹0.90 to ₹1.35 |
| Public AC | ₹10 to ₹18 | ₹1.50 to ₹2.70 |
| Public DC fast | ₹18 to ₹25 | ₹2.70 to ₹3.75 |
To compare with petrol, divide your local petrol price by your petrol car's real-world km per litre, then compare it with the EV cost per km above. Your own driving and efficiency will change the result.
Why your real home charging cost can be higher than the base rate
- Slab tariffs: Most states use slabs, so extra EV charging can push you into a higher slab. Your marginal rate may be higher than your average rate.
- Add-on charges: Fuel or power purchase adjustments, taxes and duties can raise the landed cost per unit above the headline slab rate.
- Charging losses: Around 5% to 10% of energy can be lost during charging.
- Fixed charges: A higher sanctioned load for a home charger can increase fixed monthly charges.
Do charging rates differ by state?
Yes. Each state electricity regulator sets tariffs for its DISCOMs, and slabs, adjustments and any EV-specific or time-of-day tariffs differ. Some DISCOMs offer a separate EV connection or lower overnight rates. Always check your DISCOM's latest tariff order, because published state-wise tables from third-party sites can be outdated. Public charging prices also vary by operator and location, so compare in the apps for your city (see Best EV Charging Apps in India).
How to reduce your EV charging cost
- Charge at home whenever you can. It is usually the cheapest option.
- Ask your DISCOM about EV or time-of-day tariffs. Overnight charging can be cheaper where they are offered.
- Use public DC fast charging only when needed, such as on highway trips.
- Compare operators. Prices vary between networks and even between sites of the same network. See the list of EV charging companies in India.
- Check parking and session fees at malls, hotels and offices.
- Consider rooftop solar if you have your own roof and steady daytime charging.
How many public chargers can you use?
India has 52,718 public EV charging stations, including 16,561 fast chargers for cars, according to data shared in the Lok Sabha in July 2026. That is more choice than a year or two ago, but station quality and pricing still vary. Find chargers in your city, starting with Jaipur, and read the India charging network guide.
For charging companies: show your tariff on TRANDS
Drivers compare prices before they choose a charger. Add your station address, connector types, power rating and tariff so they can find you. List your business free, claim your profile, or ask about featured placement. Planning your own station? See the EV Charging Franchise guide.
Conclusion
Home charging is the cheapest way to run an EV in India, public AC sits in the middle, and DC fast charging costs the most per kWh but saves time on the road. Use the formula with your own battery size and your DISCOM or operator tariff to get your real number.
