Fuel Cost Formula

The fuel cost for a trip depends on total distance, your vehicle's fuel efficiency, and the price of fuel. The formula first determines how much fuel is needed, then multiplies by cost per unit.

Smart Tip

"Carpooling with friends cuts your per-person cost significantly while reducing total emissions."

The Formula

Distance = Total trip distance, Efficiency = Vehicle fuel economy.
