Comparison FAQs
DriveCost multiplies your estimated annual gallons by the gasoline price you enter (or the national average). Estimated gallons = annual miles ÷ weighted MPG, where weighted MPG blends the EPA city and highway ratings using your city/highway driving split.
EPA ratings come from standardized lab tests at fueleconomy.gov. They are useful for comparing vehicles, but real-world economy varies with weather, traffic, speed, terrain, vehicle condition and driving style. DriveCost labels them "EPA-rated" and treats them as estimates.
Cost per mile = total annual operating costs ÷ annual miles. Operating costs include fuel or electricity, maintenance, tires and other recurring costs you enter. It excludes the one-time purchase price and depreciation.
Five-year energy cost is the annual energy cost multiplied by your ownership period. The full five-year ownership view also adds estimated maintenance, tires, depreciation and optional insurance/registration, using documented assumptions that are shown on the methodology page.
