EV Charging Cost Calculator — Estimate Your Electric Car’s Charging Cost
How much does it actually cost to fully charge your electric car? The EV Charging Cost Calculator gives you an instant answer based on your battery’s capacity (kWh), your electricity price per unit, and whether you’re charging at home or at a public/fast-charging station.
How It Works
Charging Cost = Battery Capacity (kWh) × Electricity Price per Unit (₹/kWh)
For example, a 40 kWh battery charged at a home electricity rate of ₹8/unit costs 40 × 8 = ₹320 for a full charge — compared to a public fast-charger, which may charge ₹15-20/unit, bringing the same full charge to ₹600-800.
Home Charging vs Public Charging
Home charging is almost always cheaper than public charging, but takes significantly longer (often 6-10 hours for a full charge on a standard home socket, versus 30-60 minutes at a DC fast-charging station). This calculator lets you compare both scenarios so you can plan charging around cost versus convenience.
| Charger Type | Typical Rate | Time for Full Charge (40 kWh battery) |
|---|---|---|
| Home Socket (Level 1) | ₹6-9 / kWh | 8-12 hours |
| Home AC Charger (Level 2) | ₹7-9 / kWh | 4-6 hours |
| Public DC Fast Charger | ₹15-20 / kWh | 30-60 minutes (to 80%) |
For accurate results, check your electric car’s actual usable battery capacity (in kWh, found in the owner’s manual or manufacturer’s website) rather than the advertised gross capacity, and use your real electricity tariff slab rather than a flat average — many states use tiered pricing where higher consumption is charged at a higher rate.
This calculator pairs well with our EV Running Cost Calculator: use this tool to estimate a single full-charge cost, and the running cost calculator to estimate your ongoing per-km or per-month energy spend.
Frequently Asked Questions
How much does it cost to fully charge an electric car at home?
For a typical 40 kWh battery at a home rate of ₹7-9 per unit, a full charge costs roughly ₹280-360, though this varies by battery size and your local electricity tariff.
Is public EV charging more expensive than home charging?
Yes, public and fast-charging stations typically charge ₹15-25 per unit compared to ₹6-9 per unit for home electricity, making home charging 2-3x cheaper on average.
How do I calculate my EV’s charging cost?
Multiply your battery’s usable capacity in kWh by your electricity price per unit (kWh). For example, 40 kWh × ₹8/unit = ₹320 for a full charge.
How long does it take to fully charge an EV?
A standard home socket (Level 1) can take 8-12 hours, a home Level 2 AC charger 4-6 hours, and a public DC fast charger 30-60 minutes for an 80% charge, depending on battery size and charger output.
