Count up the hours you spend doing the weekly tasks in your online class. Multiply that by the number of weeks the course runs. Add in the hours you spend handling before-class prep and after-class finalizing and recording grades. Divide that number by the amount of money you earn for the course. How much do you make per hour?
My hourly pay ranges from $25/hr to $60/hr. And the highest per hour school is, surprisingly, NOT the highest paying school.
Have you figured out yet how much you earn per hour teaching online?
