Overview

The EV Charging Cost Calculator estimates how much it costs to charge an electric vehicle based on battery capacity, energy efficiency (km/kWh), driving distance, and charger rate. Compare home (Level 2), public slow, and DC fast-charging costs to optimize your charging strategy.

Formula

Charging Cost = (Distance / Efficiency) x Price per kWh. Example: efficiency 5 km/kWh, 200 km, fast charge at 324.4 KRW/kWh → (200 / 5) x 324.4 = 12,976 KRW.

How to Use

1. 1Enter the vehicle's energy efficiency in km/kWh (check the official rating).
2. 2Enter the expected driving distance in km.
3. 3Select the charger type (home Level 2, public slow, DC fast) to auto-set the rate.
4. 4Click 'Calculate' to see the estimated charging cost.

Tips

• ✔Charging at home during off-peak hours (11 PM–9 AM) is the cheapest option in Korea.
• ✔Signing up for the Ministry of Environment charger network gives you a member discount.
• ✔DC fast charging (50 kW+) is convenient but costs roughly twice as much as slow charging.
• ✔In winter, efficiency drops 20–30% due to reduced battery performance in cold weather.
• ✔Consider KEPCO's dedicated EV charging tariff to avoid progressive residential electricity pricing.
