Floyd Mayweather Jr. – $565 Million

There aren’t many athletes who can compare to the earnings and net worth of acclaimed boxing champion Floyd Mayweather Jr. For a single fight; sources report that he brings in about $300 million, while Mayweather’s fortune is estimated at $450 million.

The last time that we saw the fighter of the decade in the ring was against the UFC’s Conor McGregor, where he seized victory by TKO before announcing his retirement in 2017. The defensive boxing legend found himself placing on Ranker’s best boxers of the 21st century during 2020. A recent CNN interview confirms that Mayweather is retired for good and doesn’t think that he’ll box again.
