Calculation Steps

    How Fuel Cost Is Estimated

    Trip cost is distance multiplied by fuel use, then by local pump price.

    Fuel economy

    Imperial fuel economy uses miles per gallon, so fuel used is distance divided by MPG. Metric fuel economy uses liters per 100 km.

    Shared trips

    Add travelers to split fuel cost per person. The total fuel estimate stays the same, while cost per traveler changes.

    CO2 estimate

    The gasoline CO2 figure is a rough tailpipe estimate based on fuel burned. Vehicle type and fuel blend can change the actual footprint.

    Fuel Cost Examples

    Quick estimates for common road-trip and commute scenarios.

    Weekend road trip

    300 miles at 30 mpg and $3.50/gal = about $35

    Shared round trip

    Four travelers split the same fuel cost four ways

    Metric commute

    120 km at 6.5 L/100 km and 1.85/L = about 14.43
