Cost of developing 1 hour of elearning

Here is what I use. I took the figures that Chapman put together but tried to make some meaning out of them for myself.in a handy spreadsheet.
Chapman provides some averages for three general course categories split into 3 levels of development effort across 12 development activities. While the breakdown is only provided for the average effort in each of the categories, I used the percentages derived from this to fill in the low and high effort buckets. Then, I use these numbers as a guide. For example, below you can see a course where I think my analysis will be:

1. close to the basic course/average effort
2. heavy on design
3. light on storyboarding
4. with graphics provided
5. no video
6. no audio
7. Average authoring (thanks StoryLine!)
8. Light QA Testing
9. 0 Project management (I work alone)
10. With a few reviews
11. an average pilot
12. and time for email back and forth with the client

My estimated time spent for one hour of training falls between Chapman's Low and Average effort for the basic course I am developing. (Even though I chose to put in a higher degree of time and effort into design).
Knowing the time you will spend is only part of the equation. You also have to know what you will charge. I've observed some make the rookie mistake of jumping out of the gate by charging what they used to make when they worked for a corporation. They forget that now they have all of the costs and overhead of their new business that they have to account for. So for example, assume a person had an annual salary of $65,000 as an ID, the hourly equivalent would be $31.25.

If they charged this, lost a few weeks for vacation (unpaid now), had business expenses of $10,000, and spent 25% of their time looking for clients, their effective hourly rate drops to about $21. If they had accounted for these other assumptions up front, they would have billed at a rate of $50 to reach their same prior salary, cover their business overhead, time spent engaging new clients, and their vacation. If I am just starting, and struggling to stay engaged (managing a 50/50 split between working and looking) my hourly rate would jump all the way to $75. Once I have a reasonable rate based on my desired income (what I think my work is worth - without being too greedy) adjusted for expenses and a reasonable work -v- work search split, the rest is simple math.

Attached is my spreadsheet you can use along with 3 screenrs that walk through it. My spreadsheet uses a modifier that is just a restatement of the cost per hour of training to a cost for each 5 minutes. This makes it easier for me to estimate courses that don't fit neatly into even hour buckets.
