EVEV charging cost calculator
This calculator helps you quickly estimate the cost of charging an electric vehicle and the approximate charging time in three modes: home outlet, charging station, or compare (side-by-side). It’s useful for planning both home charging and public charging sessions.
How to use the calculator
1) Enter your battery capacity (kWh), current (%) and target (%).
2) Optionally add charging losses (typically 5–15%). Losses mean you draw a bit more energy
from the grid than what ends up in the battery.
3) Choose a mode:
Home outlet — select your outlet type (power) and enter your price per kWh.
Charging station — enter the station tariff (UAH/kWh or UAH/min) and station power.
Compare — fill both tariffs to see which option is cheaper.
What the result shows
You will see: energy added to the battery, energy drawn from the grid (with losses), estimated charging time and total cost. In Compare mode, the cheaper option is highlighted and the cost difference is shown.
Tariffs for 2026
Home electricity (households) is commonly presented as a fixed price of 4.32 UAH/kWh. With a two-zone meter, a night tariff of 2.16 UAH/kWh may apply (half price). Some special cases (e.g., electric heating) can have 2.64 UAH/kWh up to 2000 kWh, then 4.32 UAH/kWh.
Public charging stations use commercial pricing set by operators. Prices vary by network, AC/DC type, location, and time. In 2026, articles and market examples often show fast DC prices roughly in the 25–32 UAH/kWh range, but real prices can be lower or higher depending on the operator.
Tip: for the most accurate result, use the tariff from your utility bill/app or from your charging network app.
Frequently asked questions
Why is “from the grid (with losses)” higher than “to the battery”?
Some energy is lost due to AC/DC conversion, heat, battery balancing, and onboard electronics. That’s why the grid energy is higher than what is actually stored in the battery.
What does “estimated charging time” mean and why can it differ in real life?
Time is calculated as grid kWh / power (kW). In real conditions, charging power may drop above ~70–80% SoC, and results also depend on temperature and vehicle/station limits.
How does the station tariff “UAH/min” work?
In “UAH/min” mode the calculator estimates charging time (minutes) and multiplies it by the per-minute price. Some networks use this model to encourage freeing the connector faster.
Does charging power affect the number of kWh needed?
Not directly. Power mainly affects time. The energy needed depends on battery capacity and the SoC difference (and losses). However, efficiency and losses can vary slightly between slow and fast charging.
What loss percentage should I use if I’m not sure?
A good starting point is 10%. Typical real-world losses are often around 5–15% depending on the vehicle, temperature, and charging setup.
