Home and public charging
At 18 kWh/100 km, electricity price alone can materially change driving cost.
| Location | Energy price | Cost per 100 km |
|---|---|---|
| Home | $0.15/kWh | $2.70 |
| Fast charger | $0.55/kWh | $9.90 |
Record energy, price and mileage together
The useful charging record combines energy, price, date and odometer. Without those values, a cheap home session and an expensive rapid charge are difficult to compare fairly.
- energy delivered in kWh
- total cost and charging location
- odometer for cost-per-distance trends
Compare home and public charging fairly
Record energy, total price and mileage for each session. Home tariffs, public charging fees and charging losses can produce very different costs even when the car’s displayed consumption stays similar.
Include charging in the full vehicle budget
Keep charging sessions beside service and other vehicle expenses rather than treating electricity as a separate household note. This makes EV running cost comparable with the rest of the car budget.
Estimate a route or follow a longer trend
Use the calculator for a planned route and saved charging entries for a longer trend. The calculator can include an optional loss percentage without storing the entered values.
