Sharing a car for a road trip is one of the cheapest ways to travel — as long as everyone chips in fairly for gas. This splitter turns the distance, your car's MPG, and the pump price into a per-person amount in seconds.
How the split works
Divide the trip distance by your MPG to get the gallons needed, multiply by the price per gallon for the total, then divide evenly by the number of people. For a round trip, enter the full there-and-back distance.
Some groups also split tolls and parking the same way, or have passengers cover gas while the driver covers wear and tear — whatever feels fair for your trip.
