Linux Foundation has estimated it would cost to develop the Linux code from scratch, the result is 10,800 million , speak specifically of the distribution Fedora 9, which was made available to the public the May 13 of 2008 .
The process of measuring software costs is a really important factor in the analysis of a project. There are various methods for estimating costs of developing software, also known as metric software .
The vast majority of these methods are based on the measurement of the number of lines of code (LDC) containing the development (excluding comments and blank lines for sources).
Costs of software development
Data development of Fedora 9
In the above-mentioned report “Estimating the Total Cost of Development to Linux Distribution” is estimated to Fedora 9 has a value of 10.8 billion dollars and the kernel would have cost only a value 1.4 billion dollars .
This distribution has some 205 million lines of code and work invested by a single person will develop alagaría for about 60,000 years .
How we’ll see in the table below ( “Trouble of a project in his role lines of code”) the project should be developed by 1000 – 5000 developers’ to ‘and that estimate does not go very misleading because in the 2 Recent years have helped some 3,200 developers although the number of workers in the history of the distribution is much higher.

By the way looking for some information about this method I found this page that contains a form with which to estimate quickly the different data estimated cost of developing a project based on the method COCOMO.
I also found a
