Your simple explanations just brought it all back! Kudos.....didnt find any of the complicated academic journals of any use! Hey Paul:

For the record - you rock. Total typo on my part. I meant for the initial cost to be $250K, but wrote the example as $200K. I've updated the text to show the proper initial values. I've also added a note explaining the update so that future readers don't think you're a loon. I really appreciate it, and hope you'll stick around and find more mistakes for us!

Where does the 250,000 value come from, for some reason I am not seeing its base. “The ROI would therefore be ($272,256 – $250,000)/$250,000 = 9%.” Where does the 250,000 value come from, for some reason I am not seeing its base.
