EV Charging Cost Calculator

See the cost of a charging session and your monthly driving, using your own electricity tariff.

Your vehicle, your numbers

Example numbers are prefilled. Replace them with your vehicle data and local prices. Currency changes the label, not the exchange rate.

Where do I find this?

Use the exact model and market in the vehicle documents. A matching name alone does not verify battery specifications.

kWh
Where do I find this?

Match usable/net capacity to the exact pack and configuration. Check whether this field asks for original or current capacity; gross capacity is different.

%
Where do I find this?

Read the battery charge percentage at the start of the scenario. This is state of charge, not state of health.

%
Where do I find this?

Choose the end charge percentage for this charging session and follow the vehicle’s charging guidance.

USD/kWh
Where do I find this?

Copy the per-kWh energy price from your bill or charging payment screen. Check whether tax is already included.

%
Share of grid energy not stored in the battery. This is an editable scenario assumption.
Where do I find this?

Enter the assumed share of grid energy that does not reach the battery. It is a scenario unless supported by measurements.

See the explanation →
kWh/100 km
Use battery-side driving consumption, not energy from your electricity bill.
Where do I find this?

Find recent driving consumption in the vehicle’s trip or energy display. Record the period and units. A charger receipt includes losses.

km
Where do I find this?

Use your expected distance for a full year, not the car’s lifetime odometer.

See the explanation →
USD/kWh
Excludes session fees and idle charges.
Where do I find this?

Use the public AC price you would actually pay; subscriptions and fixed fees may be separate.

See the explanation →
USD/kWh
Excludes session fees and idle charges.
Where do I find this?

Use the public DC price for your intended operator and plan. Do not assume it matches home charging.

A clearer picture starts here.

Review the example inputs, then calculate. We show the assumptions alongside your result.

Why is this an estimate?

The same loss assumption is used for optional tariff comparisons. Your actual loss, tariff, subscription fees and idle charges can differ.

See how the calculation works

Grid energy = capacity × (target − start) ÷ 100 ÷ (1 − losses ÷ 100). Cost = grid energy × electricity price.

The same loss assumption is used for optional tariff comparisons. Your actual loss, tariff, subscription fees and idle charges can differ.

Example: electricity bought is not all stored in the battery

A 60 kWh usable pack charged from 20% to 80% gains 36 kWh. At an assumed 10% loss of grid energy, it draws 40 kWh. At an illustrative price of 0.25 per kWh, the session costs 10 in the selected currency. Monthly and annual energy costs use the driving-distance input, not a fixed number of these sessions.

Where to get useful inputs

  • Copy the relevant per-kWh price from your bill or charging payment screen.
  • Enter prices yourself; changing currency does not perform a currency conversion.
  • Public AC and DC comparisons use the same loss assumption. Add parking, connection or subscription charges separately.
Why not just add 10% to battery energy?

Here, losses are a share of the energy drawn from the grid. To deliver 36 kWh when 90% reaches the battery, divide 36 by 0.90. Multiplying by 1.10 describes a different definition of losses.
