EV charging cost
Estimate a charge using your own tariff.
Estimated charge cost
Formula: battery × (end − start) ÷ 100 ÷ (1 − loss ÷ 100) × price
Electricity cost calculator: kWh to cost
Choose the figures you have. Enter the price from your contract or bill; the prefilled value is an example only.
kW measures power; kWh measures energy used. A label in kWh/100 cycles is not an annual figure.
Compare two tariffsEstimated cost
The formula appears for the chosen method.
Compare two electricity tariffs
Same consumption, same period. See when a lower price per kWh offsets a higher fixed charge.
Starting values are examples, not current offers. Compare prices with the same charges included.
Enter total fixed charges for your chosen period; for example, a daily fee × the number of days. The tool does not turn this into a monthly or annual estimate. Empty fixed charges mean zero. This tool does not save your entries.

Tariff A—
Tariff B—
Cost difference—
A = kWh × applicable price A + fixed charge for the entire period A
B = kWh × applicable price B + fixed charge for the entire period B
What if your consumption is uncertain?
Use the same period, rates and fixed charges as above. Starting values are examples. You choose this range; it is not a forecast.
| Consumption | A | B | Lower cost |
|---|---|---|---|
The difference A − B is a straight line: consumption × (rate A − rate B) + fee A − fee B. Checking both endpoints shows whether the cheaper option changes within the range. Only entered costs are compared, not complete offers.
