But you can estimate it. Record your earnings every day, any compare it by the hour, day, week, and month, as well as miles driven each day. Estimate the total cost of driving (IRS estimate of ~$0.50/mile is a good place to start). Use this simple formula:
(Income - expenses) / hours worked = hourly wage
Is your hourly wage reasonable? If so, it may make sense to optimize away your expenses and generally stay the course. If it's not, would changing your work hours or location make it reasonable?
Unfortunately, I get your feeling that people only look at the income and ignore the rest of the equation (hey, I got $50 tonight! I had to drive 100 miles though...). If you're making $3/trip, you had better drive less than 6 miles or you just lose.
