Cost of developing 1 hour of elearning

I just wanted to add in another resource that I've used (or really, a collection of resources): https://christytucker.wordpress.com/2013/09/09/instructional-design-hourly-rates-and-salary/

I also wanted to point out that there hasn't been much mention of agency vs. individual which may be why the prices seem to be so high for some of the calculators. An agency is likely going to have a separate ID, dev, graphic designer, project manager, etc, plus have more overhead in general.

Very few individuals are an expert at all of those items, so you're paying for the expertise in each little piece of your elearning development when hiring an agency.

Some people don't need a full agency though, and that's where we come in as freelancers.

I think Owen's example is fantastic - there's a lot that goes into pricing. 

I've also seen a couple people post the Slideshare on How Long Does it Take to Create Learning. Here it is broken down: http://www.chapmanalliance.com/howlong/ - I have used this formula once so far, and it has worked out (it actually seems to be giving me more time than it actually took, but it was a much more casual project than usual as well).
