An independent research tool that calculates driving costs using official U.S. government data. Fuel economy ratings and fuel prices sourced exclusively from the EPA via FuelEconomy.gov.
All figures are estimates for informational purposes only and do not constitute financial, legal, or purchasing advice. Actual costs vary based on driving habits, location, vehicle condition, and market factors. All data sourced exclusively from the U.S. EPA via FuelEconomy.gov (U.S. Department of Energy and Environmental Protection Agency).

Methodology. Combined MPG calculated using EPA harmonic mean formula: Combined = 1 / ((%City / CityMPG) + (%Highway / HighwayMPG)). All cost projections use current EPA fuel prices applied uniformly across ownership period. No inflation modeling or future price speculation is applied.
