EV Charging Cost Calculator
From battery size, charge levels, charging efficiency and the kWh price, work out the charging cost, grid energy, cost per 100 km, range added and charging time.
Things to keep in mind:
- DC fast-charging power drops sharply above roughly 80 %; real charging can take longer than estimated.
- Battery temperature, weather and the car's maximum accepted power affect time and efficiency.
- Per-minute, session or idle fees and subscription discounts at stations are not included.
- The electricity price is your input; with time-of-use tariffs enter the price for the hours you charge.

About this tool
This tool calculates, for charging an electric car at home or at a public station, the energy drawn from the grid, the charging cost, the charging loss, the car's cost per 100 km, the range added and an estimated charging time at a given power.
Formulas
- Energy into the battery (kWh) = capacity × (target % − start %) ÷ 100
- Grid energy = battery energy ÷ (efficiency ÷ 100)
- Charging cost = grid energy × price per kWh
- Cost per 100 km = consumption (kWh/100 km) ÷ (efficiency ÷ 100) × price per kWh
- Range added = battery energy ÷ consumption × 100
- Charging time (h) = grid energy ÷ charging power (kW)
Example
A 60 kWh battery charged from 20 % to 80 % at 90 % efficiency, 3.50 TRY per kWh, on an 11 kW wallbox: 36 kWh enter the battery, 40 kWh come from the grid and the charge costs 140.00 TRY. At 16 kWh/100 km the range added is 225 km and the cost per 100 km 62.22 TRY; the estimated time is 3.64 h (3 h 38 min).
Where to find the price
At home use the all-in kWh price from your electricity bill (Turkish tariffs are set by EPDK and change periodically); at a station use the operator's AC or DC kWh price. The tool does not hard-code any tariff.
How to use
- Enter the usable battery capacity (kWh).
- Enter the start and target charge levels and the charging efficiency.
- Enter the price per kWh (home or station).
- Optionally enter consumption (kWh/100 km) for range and charging power (kW) for time.
- Click Calculate.
Notes
Money is rounded HALF_UP to 2 decimals, energy to 2 decimals and range to 1. Charging time assumes constant power; hours and minutes come from total minutes rounded to the nearest whole minute. If the target is not above the start level, energy and cost are 0.
Frequently asked questions
Multiply the grid energy by your all-in kWh price: 40 kWh × 3.50 TRY = 140.00 TRY. Grid energy exceeds battery energy because of losses.
Charger, on-board charger and battery heating losses mean part of the energy never reaches the battery. At 90 % efficiency, 36 kWh in the battery needs 40 kWh from the grid, and you pay for 40.
Grid energy divided by the usable charging power: 40 kWh ÷ 11 kW ≈ 3.64 h. A car can only use the AC power its on-board charger supports.
Compare this tool's cost per 100 km with the per-100 km fuel cost from the Fuel Cost and Trip Expense tool. The result depends on whether you charge at home or at a station and on current prices.
Enter whatever target suits your consumption and range needs; the car and charging speed also affect the time. Because DC fast-charging power can drop sharply once the battery reaches about 80 %, high targets may take longer than estimated.
