Charging-only cost
Narrow estimateThe result covers electricity for driving, not insurance, tyres, servicing or depreciation.

EV Charging Cost Example
An EV charging estimate starts with distance and efficiency, then adjusts for charging losses and electricity prices. This example keeps the calculation narrow and readable.

Quick answer
User question: "If I drive 1,000 km a month and charge at home, what might charging cost?" In this example, the estimate is about 32 per month before public charging, installation costs or broader vehicle costs.
Primary calculator
EV Charging Cost Calculator
Use the EV charging cost calculator to enter your own distance, efficiency, electricity prices, charging mix and loss assumptions.
Example inputs
These are the assumptions used in the scenario.
- Monthly driving The example uses 1,000 km per month.
- EV efficiency The vehicle uses 16 kWh per 100 km in the scenario.
- Charging loss A 10% charging-loss allowance is included.
- Electricity price Home electricity is entered as 0.18 per kWh.
- Charging mix The simple example assumes all charging is at home.
- No installation costs Charger hardware, installation and subscription fees are outside this charging-only estimate.
Worked example
- Distance
- 1,000 km per month
- The monthly driving assumption.
- Efficiency
- 16 kWh per 100 km
- Energy used by the vehicle before charging losses.
- Driving energy
- About 160 kWh
- 1,000 km times 16 kWh per 100 km.
- Grid energy with losses
- About 178 kWh
- Includes a 10% charging-loss allowance.
- Electricity price
- 0.18 per kWh
- Home charging price used in the example.
- Estimated monthly charging cost
- About 32
- Rounded cost in the currency unit entered.
The estimate is a charging-only cost. It is useful for energy planning, but it is not the same as total vehicle ownership cost.
Result interpretation
Read the result as a scenario based on the assumptions entered, not as a decision rule.
Home price assumption
Important inputThe example uses one home electricity price. Public charging or peak rates can change the result.
Charging losses
IncludedLosses increase the grid energy estimate above the driving energy estimate.
Fuel comparison
Separate questionUse the Gas vs Electric calculator when you want a side-by-side gas, petrol and EV energy-cost comparison.
Assumptions that change the result most
Before using the tool, gather the inputs or assumptions that are most likely to move the result.
- Driving distance Monthly distance is the main volume driver. More distance means more energy needed.
- Vehicle efficiency A less efficient EV uses more kWh for the same distance.
- Electricity price Home, public and time-of-use prices can produce very different charging costs.
- Charging losses Losses mean the electricity bought from the grid can be higher than the energy used while driving.
Common mistakes
These are common ways an estimate can become cleaner than the real-world scenario.
- Using annual distance as monthly distance Check the calculator frequency so distance is not accidentally counted twelve times.
- Leaving out public charging Public charging can cost more than home charging, depending on the price entered.
- Ignoring charging losses The energy billed can be higher than the energy the car uses while driving.
- Treating charging cost as total car cost Charging is only one ownership cost. Total car cost needs a broader calculator.

FAQs
Why is grid energy higher than driving energy?
Charging losses mean some electricity is lost before it reaches the battery, so the amount billed can be higher than the driving energy estimate.
Does this include public charging?
This example uses home charging only. The calculator can model a home and public charging mix where those inputs are available.
Does the example include charger installation?
No. Hardware, installation, subscription fees and parking charges are outside this simple charging-cost example.
Can I compare this with petrol?
Use the Gas vs Electric Car Cost Calculator when the question is side-by-side energy cost for an EV and a gas or petrol vehicle.
What currency is the result in?
The calculator treats the electricity price you enter as already being in your chosen currency. It does not convert exchange rates.
Methodology and limits
This EV charging example is a general estimate only. It is not financial advice, tax advice, energy-price advice or a vehicle recommendation, and it does not include every tariff, public charger fee, charger installation cost or ownership cost.
