Start a carpoolFuel Cost FAQ
How do you calculate fuel cost for a trip?
Divide trip miles by vehicle MPG, then multiply the gallons by the gas price per gallon. For a round trip, double the one-way distance first.
How do you split gas money for a carpool?
Calculate the total fuel cost and divide it by the number of riders sharing the cost. Include the driver if everyone is splitting evenly.
Should a carpool include parking or tolls?
Fuel cost is only one part of a shared ride. Add parking, tolls, or mileage reimbursement separately when the driver pays those costs.
What MPG should I use?
Use the vehicle's real average MPG for the route. City-heavy school runs often use a lower MPG than highway trips.
