Mark Zuckerberg has made $4.4 million for every day he's been alive

Facebook founder Mark Zuckerberg's turns 32 on Saturday, and he has a few billion 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.

Obviously, there are better measures of business acumen, but it gives you a sense of how quickly business titans can amass their huge fortunes.

Look at Microsoft's Bill Gates. He's the richest person in the world, and at age 60, he's earned $3.5 million per day in his life. Jeff Bezos, 52, ofAmazon is third with a per-day fortune of $3.3 million. He's increased his rate significantly since last year. They are the only people averaging over $3 million per day.
