What is the cost estimate to build Open edX?

According to OpenHub.net, it is $5,4 million.

This math comes from considering that the size of the Open edX codebase size is 374,602 lines, the average salary of a developer is $55,000 per year and the estimated effort amounts to 99 person-years. The Basic COCOMO model, an algorithmic software cost model, was used for the estimate.
