Facebook founder Mark Zuckerberg's turns 32 on Saturday, and he has a few million things to celebrate. With a fortune estimated at $51.8 billion, he's one of the world's richest people. But because of his youth, he's actually made more money per day of living than anybody else on the planet.

Specifically, Zuckerberg's potent combo of youth and wealth has averaged out to $4.4 million for every day he's been alive, according to CNBC calculations. That rate is bigger than anybody else on Forbes' list of billionaires.
