The formula
In miles: cost = distance ÷ mpg × price per gallon. In kilometres: cost = distance ÷ 100 × litres per 100 km × price per litre. For an electric car: cost = distance ÷ 100 × kWh per 100 × price per kWh.
Getting the inputs right
- Use your car's real-world economy, not the official figure, which is usually 10% to 20% better than real driving.
- Highway trips use less fuel than city driving in most gasoline cars; electric cars are the opposite.
- Charging at home is usually far cheaper than fast chargers on the road. Use the price you will actually pay.
