Formula

Fuel Cost = (Distance / MPG) × Fuel Price

Calculate your fuel economy in MPG, cost per mile, and annual fuel costs. Convert between MPG, L/100km, and km/L.

Estimate the total cost of a road trip including fuel, hotels, meals, and tolls. Split costs between passengers.

Calculate the cost to charge your electric vehicle at home or at a station. See charging time estimates for Level 1, 2, and DC fast charging.
