How do you compare an electric car with gasoline and ethanol?
The calculator turns electricity rates, fuel prices and vehicle efficiency into a cost per kilometer. You can quickly see the monthly cost of driving the same distance with each option.
When does an electric car really pay off?
Lower charging costs do not automatically mean a lower total cost. The complete model adds purchase price difference, home charger, maintenance and resale value to estimate payback and minimum driving distance.
Frequently asked questions
