Calculate the cost of charging an electric vehicle for any journey with our free EV Journey Cost Calculator. Enter your trip distance, vehicle efficiency and electricity tariff to estimate the total charging cost, cost per mile, energy required and how much of your vehicle’s range the journey will use.
Whether you are planning a single trip, estimating weekly or monthly running costs, or comparing home charging with public rapid charging, the calculator helps you understand the real cost of driving electric.
You can adjust the calculation for temperature and driving style, or select a popular vehicle to use a realistic efficiency figure. Default electricity rates are based on typical UK benchmarks, and you can also enter your own custom tariff.
Please note: This calculator is for guidance only. Actual electricity consumption and charging costs will vary depending on the vehicle, driving conditions, weather, payload, speed, charging losses and the exact tariff you pay.
EV Journey Cost Calculator
Estimate the cost of charging an electric vehicle for any journey. Adjust for temperature, driving style and electricity tariff.
1 Trip Distance
Enter a one-way trip, daily commute, monthly or annual total — whatever you need to cost.
2 Vehicle Efficiency
City driving is typically more efficient. Cold weather reduces real-world range significantly.
3 Charging Tariff
Defaults reflect typical UK rates. Public rapid charging is significantly more expensive than home charging.

How to Use the EV Journey Cost Calculator
1. Enter your trip distance
Add the number of miles you plan to travel. This can be a one-way journey, a daily commute, or a monthly or annual total.
2. Select or enter vehicle efficiency
Choose a popular electric vehicle from the presets or enter your own miles-per-kWh figure. You can also adjust for driving style (City, Combined or Motorway) and temperature to reflect real-world conditions more accurately.
3. Choose your charging tariff
Select Domestic Cheap (off-peak home charging), Domestic Standard, Public Rapid, or enter your own electricity rate in pence per kWh.
4. Review the results
The calculator shows the estimated total charging cost, cost per mile, energy required in kWh, and the percentage of the vehicle’s typical range used for the journey.
What Affects EV Journey Costs?
Several factors influence how much it costs to charge an electric vehicle for a given journey:
- Distance – Longer trips require more energy and therefore cost more to charge.
- Vehicle efficiency – Measured in miles per kWh. A more efficient vehicle will use less electricity for the same distance.
- Driving style – City driving is often more efficient than motorway driving. Aggressive acceleration and higher speeds increase energy use.
- Temperature – Cold weather reduces battery efficiency and range. Heating the cabin also draws additional power.
- Charging location and tariff – Home charging (especially off-peak) is usually far cheaper than public rapid charging.
Businesses looking at the wider picture of electric vehicle costs may also find our Electric Vehicle Running Cost Calculator useful for estimating annual, monthly and per-mile electricity expenditure.
Understanding the Results
- Total charging cost – The estimated cost of the electricity needed for the journey at the selected tariff.
- Cost per mile – Average electricity cost for each mile travelled.
- Energy required – How many kilowatt-hours (kWh) the vehicle is estimated to use.
- Range used – The proportion of the vehicle’s typical real-world range that the journey would consume. If this figure exceeds 100%, a mid-journey charge is likely to be needed.
Home Charging vs Public Rapid Charging
Home charging, particularly on an overnight or EV-specific tariff, is typically the cheapest way to power an electric vehicle. Public rapid chargers (often found at motorway services and dedicated charging hubs) are considerably more expensive per kWh.
Using the calculator to compare different tariffs can help fleet managers and drivers understand the cost impact of relying on public charging versus maximising home or depot charging. For businesses that reimburse employees for home charging, our guide to home EV charging reimbursement for fleets explains the key considerations.
Drivers using fully electric company cars may also want to compare actual charging costs with HMRC’s Advisory Electric Rates using our AER Reimbursement Calculator.
