9 Mind-Blowing Facts That Show Just How Wealthy Jeff Bezos, the World's Richest Man, Really Is The Amazon CEO is worth an estimated $121 billion.

Jeff Bezos is the richest person on the planet. Worth an estimated $121 billion, the Amazon CEO is $16 billion richer than the world's next-richest person, Bill Gates.

Bezos even retained his ranking as the world's richest person following his divorce from MacKenzie Bezos, after which she kept a 4% stake in Amazon worth roughly $35.7 billion, making her the third-richest woman in the world.

Although his annual salary is only $81,840, most of Bezos' wealth comes from his Amazon shares. The world's richest man makes $2,489 per second -- more than twice what the median U.S. worker makes in one week, according to calculations by Business Insider.

1. Bezos is worth $121 billion despite being paid an annual salary of just $81,840, less than what most U.S. representatives take home.

Of course, a large portion of Bezos' wealth is tied to Amazon stock, not his salary.

Business Insider previously calculated how much Bezos actually makes in a year, based on the change in his net worth year-over-year, and found it to be closer to $8.9 million.

What's even more impressive is if you break that down to how much Bezos makes every day, every hour, and even every second.

2. Bezos makes $2,489 per second -- more than twice what the median U.S. worker makes in one week.

That's $149,353 per minute.

As Business Insider's Hillary Hoffower previously reported, that means that in just one minute, the Amazon chief makes more than three times what the median US worker makes in a year -- $45,552. These numbers were calculated shortly before the Bezos divorce.

3. After divorcing MacKenzie and giving up 25% of the Amazon stock co-owned by the couple, Bezos still kept his ranking as the richest person in the world.

MacKenzie, on the other hand, is now the third-richest woman in the world after L'Oreal heiress Francoise Bettencourt Meyers and Walmart heiress Alice Walton.

MacKenzie, who was one of Amazon's first employees, is now worth an estimated $38.9 billion.

4. With his $121 billion, Bezos could theoretically buy more than 30% of the top 100 U.S. college endowments.

The top three richest colleges in the U.S. -- based on the size of their endowments -- are Harvard University with $38.3 billion, the University of Texas system with $30.89 billion, and Yale University with $29.35 billion.

Bezos' fortune is greater than those three universities' endowments combined -- with more than $22 billion to spare.

5. Bezos is so rich that an average American spending $1 is similar to Bezos spending $1.2 million.

The median net worth of an average U.S. household is $97,300. Dividing $121 billion by $97,300 comes to about $1.2 million, according to previous calculations by Business Insider.
