EV or combustion car: compare cost, energy use and daily driving
This comparison is about the full cost of using a car, not the purchase price alone. Energy price, consumption, mileage, maintenance, fixed costs and depreciation determine which option is cheaper over the chosen period.
Quick answer
Quick answer: when is an EV cheaper in everyday use?
The cheaper car is usually decided by mileage, energy price and holding period, not by fuel cost alone. Depreciation, insurance, maintenance and tyres belong in the comparison.
Example
Example: Total cost beats fuel-price intuition
Start by clarifying which car is cheaper over the period of use. Then the comparison clarifies the effect of energy price, consumption, mileage, maintenance and fixed costs and the boundary set by depreciation, charging price, repairs and driving profile.

How to read the resultDecision focus: which car is cheaper over the period of use. Separate check: depreciation, charging price, repairs and driving profile.
Read the result together with energy price, consumption, mileage, maintenance and fixed costs. Depreciation, charging price, repairs and driving profile limit how directly you can act on it.
Decision view
Total cost beats fuel-price intuition
The overview separates result, lever and boundary: which car is cheaper over the period of use; energy price, consumption, mileage, maintenance and fixed costs; depreciation, charging price, repairs and driving profile. This turns the graphic for EV or combustion car into decision support rather than decoration.
The three areas of interpretation
The colours connect the overview with the explanations: result, main lever and separate check remain readable.

Separate checkdepreciation, charging price, repairs and driving profile
The practical benefit becomes clear only when energy price, consumption, mileage, maintenance and fixed costs are realistic and depreciation, charging price, repairs and driving profile are checked separately.
How it is calculated · Mathematical background
How it is calculated
The starting point is energy price, consumption, mileage, maintenance and fixed costs. The transfer limit comes from depreciation, charging price, repairs and driving profile.
Set annual mileage
Annual distance determines how strongly energy costs matter.
Enter consumption
Electricity use in kWh and fuel use in litres are treated separately.
Apply energy prices
Electricity, petrol or diesel prices determine the cost per kilometre.
Calculate annual cost
Cost per kilometre × annual mileage gives the running energy cost.
Compare fairly
Both options need the same mileage and realistic price assumptions.
Interpret the decision
The comparison gives direction, but it is not a full purchase or leasing analysis.
The statement helps when which car is cheaper over the period of use. Before binding steps, depreciation, charging price, repairs and driving profile remain separate.
Detailed calculation explanation
In simple terms: annual energy cost = annual mileage × consumption per kilometre × energy price. For EVs the model uses kWh, for combustion cars it uses fuel consumption. A fair comparison needs the same mileage, realistic prices and separate checks for purchase price, maintenance and depreciation.
If-then rules
If-then rules for the decision
When usage or prices can change
energy price, consumption, mileage, maintenance and fixed costs set the main driver. The statement is robust when less favourable assumptions still work.
When choosing technology or tariffs
depreciation, charging price, repairs and driving profile also decide whether the calculation can become a binding next step.
When planning the next step
The next action should read the calculated value, main lever and model boundary together.
Step by step
How to interpret this topic
Read demand and generation
The central value needs a clear question: which car is cheaper over the period of use. depreciation, charging price, repairs and driving profile stay beside the number for interpretation.
Find the strongest energy lever
The main driver is energy price, consumption, mileage, maintenance and fixed costs. Small changes here can matter more than additional details.
Keep model limits realistic
Beside the result sit depreciation, charging price, repairs and driving profile. This is where calculation ends and judgement begins.
Plan the next energy step
The calculation becomes practical when which car is cheaper over the period of use leads to a concrete action with enough margin.
Checklist
Quick checklist
- Define the starting question: which car is cheaper over the period of use.
- Vary the main lever within the same scenario: energy price, consumption, mileage, maintenance and fixed costs.
- Keep the boundary separate: depreciation, charging price, repairs and driving profile.
- Compare base case and cautious case only with the same reference value: which car is cheaper over the period of use.
- Turn the result into action only when energy price, consumption, mileage, maintenance and fixed costs and depreciation, charging price, repairs and driving profile remain plausible together.
Common mistakes
Common mistakes
EV or combustion car: reading the result without context
The value helps only when its purpose is clear. Otherwise details hide the boundary from depreciation, charging price, repairs and driving profile.
EV or combustion car: setting the main lever too optimistically
energy price, consumption, mileage, maintenance and fixed costs should not be set as wish values. Otherwise the normal case gets confused with the best case.
EV or combustion car: overlooking the model boundary
A binding step needs both the result and a clear view of depreciation, charging price, repairs and driving profile.
FAQ
FAQ about EV vs Gas Car Cost Calculator
What is EV vs Gas Car Cost Calculator useful for?
If energy price, consumption, mileage, maintenance and fixed costs are uncertain, the decision should not depend on the most favourable scenario.
When is a second scenario worthwhile?
The best comparison value is the one that turns an acceptable result into a risky one.
Where does the calculation stop?
The result is useful for orientation. Binding steps also need a view of depreciation, charging price, repairs and driving profile.
