EV Charging Cost Calculator
Compare home-only, mixed and public-only EV charging costs using your consumption, weekly distance, tariffs and charging losses.

How the calculation works
Energy at the battery is km/year × consumption ÷ 100. Because charging is not perfectly efficient, grid energy is that figure divided by (1 − losses). Your weighted tariff blends home and public rates by the share you charge at each, and we also show home-only and public-only scenarios.
What this does not include
Real-world efficiency varies with driving style, climate, speed and terrain, so this does not imply an exact vehicle efficiency. Subscription fees and idle/connection fees at public chargers are not modelled.
How to improve the estimate
Use your vehicle's real kWh/100km from the trip computer, your actual home tariff, and a realistic public-charging share and rate for your area.
How we calculated this
This estimate uses transparent inputs and a fixed formula. See our methodology for how ranges, sources and assumptions work.
