Fuel cost questions
Where do the MPG figures come from?
From fueleconomy.gov, the official US fuel economy site of the EPA and the U.S. Department of Energy. They are the EPA test results for each car, the same figures as on the window sticker.
Where do the fuel prices come from?
The suggested prices are the US averages published by fueleconomy.gov (read on Nov 13, 2026). Prices differ by state and station, so enter what you pay.
Why is my real MPG different?
EPA figures come from a standard test. Your result depends on speed, traffic, weather, tire pressure, load and how you drive. Use the city/highway share to match your driving.
How is an electric car worked out?
With the EPA figure in kWh per 100 miles and your price per kWh. Charging at home is usually much cheaper than fast charging, so enter the price you really pay.
How are plug-in hybrids worked out?
On gasoline only. The real cost is lower when you charge it and drive on electricity.
