You can prepare a financial cost-benefit analysis for each session.

Hours Worked: (please format in decimals, not minutes, so 3:15 = 3.25, :30 = .5, etc.)
Hourly Fee: $
Expense Reimbursement: $
Total Unpaid Time: (In hours - include travel, other unpaid time)
Total Costs: $ (food, travel, supplies)


You can prepare a financial cost-benefit analysis for each session by adding together all income (fee and expense reimbursement) for that session, subtracting costs not reimbursed from the total income, then dividing by the total number of hours involved, including travel and waiting time.

If this ratio seems lower than your time is worth, and there are no reasons of friendship, education, professional advancement, curiosity, and such that make you want to repeat work with people, discuss the possibility of raising your fee or getting transportation reimbursement. If this doesn't work out, look for appointments somewhere else.
