Compare the annual energy cost of an electric car and a gas car, based on mileage, consumption and price per kWh/liter.
The calculator computes annual energy cost for each car type separately, then finds the difference:
The calculator only looks at energy/fuel cost. Purchase price, taxes, insurance, service, maintenance and depreciation aren't included, but can make up a large share of total ownership costs.
Electricity prices vary with season, time of day, region and plan. Gas prices vary with crude oil prices, taxes and local competition. Use an average for a more representative figure.
Not necessarily. Energy cost is often lower for an EV, but the full picture also depends on purchase price, mileage, access to charging, and other ownership costs not included in this comparison.
