Floyd Mayweather

It’s not a huge surprise that Floyd Mayweather is one of the richest athletes of all time. After all, the professional boxer was Forbes’ highest-paid athlete and celebrity of 2015.

In addition to his $300 million 2015 salary, Mayweather made approximately $15 million in endorsements. CelebrityNetWorth.com reports that the boxing champion’s salary is $100 million per fight — way more than his first paycheck of $10 million, according to Forbes — and his total career earnings come out to around $700 million.
