The highest-paid athletes in the world compete in such sports as American football, soccer, basketball, tennis, and boxing. They make a combined annual salary that tops $778 million, according to the latest listing by Forbes magazine. However, their income is not limited to just salary or participation fees. Together, these athletes also pulled in more than $500 million in endorsements. At least three athletes on the list make more money from endorsing products than they do playing their sport.

1. Floyd Mayweather, Jr.

This undefeated boxing champion in several weight classes retired with a record of 50-0. In 2016, ESPN declared him to be the greatest boxer, pound for pound, in the last 25 years. During his career, Mayweather has made more money – $285 million – than any other athlete in the world. He is one of the most popular pay-per-view attractions ever and has generated approximately 23.8 million pay-per-view buys and $1.67 billion income for the company.
