Code Duplication Removal ROI Calculator

I found some interesting website which provides visitor with nice return on investment calculator: http://www.semanticdesigns.com/Purchase/CloneCalc.html

The basis for the estimate is Brenda Baker paper “On Finding Duplication and Near-Duplication in Large Software Systems.” You can find it for example on IEEExplore (http://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=514697&isnumber=11405).

Bottom line: on average 13%-20% of the code can be removed (as is a result of code duplication) making maintenance of the project significantly cheaper. Assuming that code maintenance is proportional to its' size - up to 20% cheaper.

So if you are spending $70,000+ on your software engineer and have 5 of them maintaining the code invest $5,000 on code duplication removal product and get your money back in less than a month. Within a year you will be $30,000 up in the blacks. On average of course. Not bad.
