How to Calculate an EV's Running Cost Per Kilometer

An electric vehicle's running cost per kilometer comes from multiplying its energy consumption per 100 km by the local electricity rate, a simpler calculation than a petrol vehicle's since there's no separate mileage-in-a-different-unit conversion involved.

How to Calculate the Cost of Charging an EV (Accounting for Charging Loss)

Charging an EV isn't perfectly efficient — some energy is lost as heat during the AC-to-DC conversion process, so the energy actually drawn from the wall (and billed by the utility) is always somewhat more than the energy that ends up stored in the battery.

Petrol vs EV: How Running-Cost Savings Are Calculated

Comparing a petrol vehicle's running cost to an electric vehicle's requires converting both into a cost per unit of distance using each vehicle's own consumption metric — liters per distance for petrol, kilowatt-hours per distance for electric — since the two vehicles don't share a common fuel unit to compare directly.

Why Charging Losses Raise Your Real EV Cost Per Km

A simple EV running-cost estimate based on energy consumption per 100 km can understate the true cost per kilometer, because it doesn't account for the energy lost as heat during charging — energy you're billed for but that never reaches the battery.
