Manny Pacquiao's done quite well in the ring. His record reflects it, so does his checkbook.
The website celebritynetworth.com estimates Pacquiao's net worth to be at $70 million. That would skyrocket with a fight against Floyd Mayweather Jr., but it appears that won't be happening anytime soon. Pacquiao announced last week he will be returning to the ring on May 7, but his opponent remains unknown.
The three most likely names being thrown around are Shane Mosley, Juan Manuel Marquez, and Andre Berto.
Neither have made near the money Pacquiao has, but some boxers have exceeded him. Besides revenue strictly from boxing, some have invested well while others have made additional money off investments and others business interests, along with income from boxing.
Here's a list of the top 10 biggest cash cows, with net worth from celebritynetworth.com.
Net worth: $1 million
The figure is quite different from his peak, when it was believed his net worth was over $400 million. Tyson squandered it, but we have to put him on the list still: Six of his past fights still hold records for pay-per-view sales, including the 1997 rematch with Evander Holyfield.
Known as the "Bite Fight," it drew 1.99 million pay-per-view buys.
Net worth: $1 million
When he divorced from his previous wife in 2000, boxingscene.com reports Holyfield's net worth was at $90 million.
But his home went into foreclosure in 2008, and he also urged a judge to reduce child support payments since he wasn't make what he used to. Holyfield has 11 children, according to numerous websites.
Net worth: $45 million
The former pound-for-pound king was a staple of HBO broadcasts, and later ventured into promoting as well as the music industry.
Net worth: $60 million
The former heavyweight champion saw his first fight with Evander Holyfield land 1.2 million pay-per-view buys in 1999. Then in 2002, nearly two million in tuned in via pay-per-view to see him and Mike Tyson fight.
Net worth: $70 million
A Filippino newspaper broke it down in detail, showing how Pacquiao earned $27.5 million just on fights alone from March 2008 to November 2009.
That didn't include earnings from pay-per-view. In his fight with Miguel Cotto, the paper also reports he earned $10 million from the 1.25 million pay-per-view buys.
Net worth: $80 million
Let's forget about his past fights and consider just his name brand alone and the memorabilia linked to him. He also has a museum dedicated to him in his hometown of Louisville, Kentucky.
Net worth: $90 million
The man who calls himself "Money" could earn so much more if he fights Manny Pacquiao. His fight with Oscar De La Hoya in 2007 was record breaking, with 2.4 million pay-per-view buys. Mayweather also reportedly earned over $10 million for the fight.
Net worth: $100 million
Besides being the marquee fighter of his era and fighting in some of the biggest fights in boxing history, he also became an advertiser's dream and made the famous commercial with his son. Leonard also benefited from investments he's made.

You guessed it—the George Foreman grill made this former champ the cash cow. In a 2004 article in Businessweek magazine, Foreman didn't reveal how much he made as an endorser, but didn't argue his lifetime earnings were near $240 million.
Besides the grill, keep in mind Foreman's also been a motivational speaker and worked as a commentator for HBO.
