EV Charging Cost & Time Calculator
Calculate EV charging cost & time
This calculator tells you in seconds what a charge costs and how long it takes. Enter battery capacity, target charge level, charging power and your electricity price.
How it works
- Enter your EV battery capacity in kWh (see the data sheet/registration).
- Set the charge level from–to in percent and your wallbox/station power in kW.
- Add your price per kWh – result: energy added, cost and duration.
Charging cost depends on battery size, charge range and electricity price; charging time also on power. Home wallbox charging is usually cheaper than fast charging – with the right cable (Type 2/Mode 3) you stay flexible at both.
Frequently asked questions
How do I calculate charging cost?
Energy added kWh = capacity × (target − start level) ÷ 100. Cost = kWh × electricity price.
Why does my car charge slower than the wallbox?
The weakest link limits it: on-board charger, cable/plug or connection. A Mode-3 Type-2 cable with enough amps uses the power optimally.
How much does a single charge cost?
For a 60 kWh battery charged from 20 to 80 %, about 36 kWh are added — at a home wallbox (≈0.35 €/kWh) that is roughly 12–13 €, at a fast charger (≈0.60 €/kWh) around 22 €.
How much does 100 km cost — compared with petrol?
At about 18 kWh/100 km and 0.35 €/kWh the distance costs around 6 €. A petrol car using 7 l (1.70 €/l) costs about 12 € — roughly twice as much.
How long does a charge take?
Charging time equals the kWh added divided by the charging power: 36 kWh on an 11 kW wallbox takes about 3.3 hours, on a 50 kW fast charger only around 45 minutes.
