I was surprised at the amount of debt they calculated. It translated to about $4600 which is 70-80 hours of work @ $65/hour. I think it was underestimated but calculating value in this way makes it very easy to understand the impact.

He was also primarily focused on old debt. Unless we calculate the future value of debt we are presently incurring we will have a very incomplete picture. That said, if we could value new debt incurred in current projects we would have a more realistic way of explaining the true cost of an application.
