You, as a provider, get to choose how much your courses cost and how many credits they are valued at. Take into account what it took to get the courses approved, the quality of the content and course, and how many others are offering similar courses.
For hosting with Table Mesa, we have some suggestions based on our research and metrics. As a general guideline, we suggest pricing courses at about $10 per credit hour. Most of our current courses range from about $10-30, but depending on the content, we have seen courses range up to $100+ and still be successful.
