His net worth is estimated to be 71.5 billion dollars as of September 2017, and he is ranked by Forbes as the fifth richest person in the world.

Zuckerberg launched Facebook from his Harvard University dormitory room on February 4, 2004. He was assisted by his college roommates and fellow Harvard students Eduardo Saverin, Andrew McCollum, Dustin Moskovitz, and Chris Hughes. The group then introduced Facebook to other college campuses. Facebook expanded rapidly, reaching one billion users by 2012. Meanwhile, Zuckerberg was involved in various legal disputes brought by others in the group, who claimed a share of the company based upon their involvement during the development phase of Facebook.

Mark Zuckerberg has a success story so great that most people could only wish for a tenth of what he's managed to accomplish. Despite all of his success, he comes from a modest background and normal parents.
