What this figure is
It is EPA's own annual cost estimate, the kind printed on a new car's window sticker. It assumes 15,000 miles a year, 55% of them in the city and 45% on the highway, at the national fuel prices EPA uses, which it revises from time to time.
To estimate your own cost, scale it by your mileage: someone who drives 10,000 miles a year would pay about two thirds of the figure. Fuel prices where you live move it too. The gas mileage ratings come from EPA's standard laboratory tests.
