How to Split Carpool Costs Fairly
Enter the round-trip distance, your vehicle's MPG, the gas price, and how many people are sharing the ride. The calculator divides the total fuel cost equally. If the driver should ride free, check the box and passengers split the full cost.

Carpooling Cost-Sharing Etiquette
Most carpools split fuel costs equally. Some groups let the driver ride free since they provide the car and absorb wear-and-tear costs. For long road trips, consider also splitting tolls and parking. Use this calculator to agree on a fair number before the trip.
