Doesn't make much sense anyway. So you make $40/hr, 40 hours a week. Well there is 168 hours in a week, subtract 40 from that and you have 128 hours those 40 hours must pay for.

As if that wasn't enough you have a lot of expenses that are flat-rate that you must pay regardless of how you spend your time (such as your rent).

All this is further assuming that your goal is to spend everything you make every month. Most probably put away some money to be able to buy a new car, travel etc. (or even just to be able to repair the car when it breaks)
