There is a really cool carpool app out in the android market called "Carpool Calculator". It lets you add passengers at any point in your trip and it keeps track of how much each person owes you by using your phone's GPS. I've been using it because I carpool with several people and we meet at different locations so the math can get a little tricky and it's just hard to keep up with without a tool like carpool calculator.

At http://www.backseatsurfing.com you can also calculate the traveling expenses. Perhaps such an app is more easy when you are driving around but this can be done beforehand as well.
