It's probably safe to assume that Mark Zuckerberg has a bit more cash on hand than the average person, but until today, we weren't exactly sure how much the Facebook CEO, and other company execs, were taking home each year.

According to paperwork filed with the SEC yesterday in conjunction with Facebook's much-publicized IPO, Zuckerberg took home about $1.5 million in salary, bonus, and other compensation. But that's pocket change compared to his stock holdings. The social network's founder owns 533.8 million shares, or 28.4 percent, of Facebook stock.

With a potential valuation up to $100 billion, that could make Zuckerberg worth about $28.4 billion.

Specifically, Zuckerberg last year earned a base salary of $483,333 and took home $220,500 in bonuses and $783,529 in other compensation, which included use of a private jet, as well as real estate and financial planning.

With billions in stock, however, Zuckerberg will switch to a $1 per year salary in January 2013. He is also the "holder of the majority of the voting power," the filing said.

Also not faring too badly is Sheryl Sandberg, Facebook's chief operating officer. She earned about $300,000 in salary and more than $86,000 in bonuses, but the approximately $30.5 million in stock awards put her total 2011 compensation at $30.8 million.

Similarly, engineering vice president Mike Schroepfer saw his total compensation reach $24.7 million last year, primarily due to the $24.3 million in stock awards. CFO David A. Ebersman was at $18.6 million and general counsel Theodore W. Ullyot was at the "low" end of things at $6.9 million.

In the filing, Facebook said in 2011, its executive salaries "were below market relative to our Peer Group, both to retain the ethos of a start-up company and because of our emphasis on equity-based compensation." In 2011, however, Zuckerberg got a $100,000 pay raise, while other execs saw their base salaries jump $25,000.

Facebook also provided details on payment to family members, which included Zuckerberg's sister Randi, who served as marketing director. She left Facebook in August to start her own company, but in the last three years, Randi Zuckerberg earned salary, bonus and other compensation of $128,750, $139,578, and $89,536.
