It's been a unique journey for Manny Pacquiao. Arguably the most accomplished and famous athlete to ever come from the Philippines, Pacquiao grew up in the slums of General Santos City and rose to become one of the greatest pound-for-pound boxers of all-time and take home roughly $500 million.

Defeating Timothy Bradley by unanimous decision on Saturday, Pacquaio reportedly made at least $20 million for his last career bout. It was another financial boon for one of the most recognizable figures in the sport.

According to Forbes estimates, Pacquiao ranks second all-time in career earnings, trailing only Floyd Mayweather, who made over $700 million.

Pacquiao’s biggest payday by far came in his May 2 mega-fight against Mayweather. He lost by unanimous decision and made a little more than half of what Mayweather earned, but Pacquiao still reportedly walked away with about $120 million for one night’s work. The pay-per-view grossed close to $600 million, and it helped make Pacquiao the second highest paid celebrity of 2015.

Before fighting Mayweather, Pacquiao had been routinely earning at least $20 million per fight. He earned about $25 million to fight relative unknown Chris Algieri before he faced Mayweather. Pacquiao was guaranteed $20 million when he fought Bradley for a second time in 2014.

Pacquiao has come a long way since his first fight in 1995. At just 16 years old, Pacquiao fought for $20 in his native Philippines, traveling three hours by boat to get to the fight venue. He would eventually land a featherweight title bout in 2003 against Marco Antonio Barrera at the Alamodome in San Antonio, Texas, knocking out the famed Mexican fighter on his way to becoming an eight-division world champion.

As his popularity grew with exciting fights and a string of knockouts against top competition in the second half of the 2000s, Pacquiao became one of the all-time great PPV draws. His 2008 fight with Oscar De La Hoya grossed 1.25 million buys, and four of his next six fights surpassed one million buys. In fights against Antonio Margarito, Shane Mosley and Juan Manuel Marquez from Nov. 2010 to Nov. 2011, Pacquiao generated 3.6 million PPV buys.

Endorsements also piled in for the Filipino icon, with Forbes reporting that he earned $12 million from deals in 2015. In February, Nike ended their endorsement deal with Pacquiao after the boxer made homophobic remarks.

Despite his massive earnings in the ring, Pacquiao hasn’t been able to completely avoid financial troubles. He faced charges of tax evasion when Philippine authorities claimed he owed $75 million in unpaid taxes from earnings in 2008 and 2009.

With his boxing career seemingly ending, Pacquiao is looking to become a senator in the Philippines. Speculation has persisted that the 37-year-old may once again return to the ring. He owns a 58-6-2 record, winning four of his last five fights.
