Electric Vehicle Cost Calculator
Calculate the running cost per kilometer of an electric vehicle from its energy consumption and your electricity rate.
- Free to use
- Accurate results
- No registration required
- Works on all devices
EV cost per km = (energy consumption in kWh/100km × electricity rate per kWh) ÷ 100. Enter your figures to calculate it.
Check your EV's spec sheet or trip computer — typical EVs use 12-20 kWh/100km.

AI explanation
Formula
Cost per 100 km = energy consumption (kWh/100km) × electricity rate (per kWh)Worked example
15 kWh/100km at ₹8/kWh
| Field | Value |
|---|---|
| Energy consumption (kWh per 100 km) | 15 |
| Electricity rate (per kWh) | 8 |
| Cost per km | 1.2 |
| Cost per 100 km | 120 |
Assumptions
- Uses your home/charging-point electricity rate — public fast-charging rates are often significantly higher per kWh than home charging.
- Does not include charging losses (energy lost as heat during charging) — see the EV Charging Cost Calculator for that.
Frequently asked questions
How do I find my EV's energy consumption figure?
Check your vehicle's trip computer or infotainment display (often shown as kWh/100km or Wh/km), or refer to the manufacturer's published efficiency figure.
Why is my electricity rate different at different times of day?
Many electricity providers use time-of-day (ToD) tariffs, charging less during off-peak hours (often late night) — charging your EV overnight can meaningfully reduce your running cost if your provider offers ToD rates.
How does EV running cost compare to petrol?
Use the Petrol vs EV Cost Calculator to directly compare monthly running costs for both, based on your actual driving distance.
