REVEALED: Floyd Mayweather's net worth after knocking out Conor McGregor

• 'Money' took home a cool $100m guaranteed but will have upside from pay-per-view revenue

Floyd Mayweather stopped Conor McGregor with an emphatic 10th round TKO but the hard work was already done long before.

'Money' moved to 50-0 but that meant little compared to the incredible £500m the fight was reportedly worth when considering revenue from pay-per-view and gate revenue.

For a man obsessed with money, it was the perfect storm: a fight where the outcome or risk, both in terms of his official record and the potential damage physically in the ring, was minimal.

Mayweather looked like he had come in from a run in the post-fight interview with Showtime, accept a slight cut to his eyebrow.

What is Floyd Mayweather’s net worth?

Mayweather has changed the face of the game in terms of prize fighting.

When you can fight Andre Berto, a fringe world level fighter throughout his career, for $32m, why risk fighting Manny Pacquiao in his prime or taking on a young lion like Errol Spence Jr or Terence Crawford right now?

His fight with Manny Pacquiao broke all records, despite missing its window for a competitive duel by a few years, landing 4.6 million PPV buys, a total gate worth $73m and sponsorships totalling $13m.

All together the Pacquiao fight produced $600m to become the highest-grossing day in sporting history—wow!

The Las Vegas resident became cosy atop of Forbes rich list for highest paid athletes in 2012, 2013 and 2014 and ranked number 34 in a list of America's richest entrepreneurs under 40 last year, but has now turned 40 years of age.

While Mayweather earned $100m basic from the Pacquiao fight, he brought home a total of $220-240m once the PPV revenue was divided up, meaning a 40 percent cut.

So Mayweather earned 120 percent more than his basic fee for fighting when it was all said and done, so we can expect at least that this time around and probably more given expectations of new records for PPV buys.

Based on Forbes' initial $340m worth before the fight, Mayweather will now be worth at least $580m (£450m)
