- Fuel profile built from your actual mileage and local prices
- Fuel tracker: what you really spend, month by month
- Insurance and fuel folded into 5-year cost to own
- Compare any two cars on total cost, not sticker price
- No ads, no tracking — and much more
How we count
Fuel-economy figures come from EPA fueleconomy.gov — the same laboratory numbers printed on the window sticker. We don't adjust them; real-world consumption depends on how and where you drive.
What we add is money. Yearly cost assumes 12,000 miles at $3.20 a gallon — change either and the ranking stays, only the size of the bill moves. Cost per mile is the same figure divided out, useful when comparing a commute against a weekend car.
