Paycheck

Hello, I am the wife of a truck driver that recently sign on with Malone, its been a week He does all the driving and I take care of the rest such as booking loads, faxing paperwork, keeping records and figuring out our paycheck. The problem is I am having a difficult time, figuring out how much we will make at the end of the week, I guess what i am saying is how much will we make off of each load, which in turn let me know which loads too accept. Could some one help me out with a simple formula. what does it mean you get 75% of the line haul and 100% fuel charge. and when I go to the load board, I know the line haul means, what the truck will make plus fuel surcharge, is that correct? What I am confused about is the fuel surcharge, is the fuel surcharge from the load board, is the actual amount they give you for gas, to make that run? I talk to a agent and she said it wasn't. Can someone help, I am trully confused. Thanks Jendayi
