How much money will Floyd Mayweather make from Conor McGregor fight?

After earning nearly a billion dollars during his legendary career, Floyd Mayweather will be making one last withdrawal from the bank of big-money boxing before hanging his gloves up for good

Floyd Mayweather has never shied away from sharing the details of his personal finances with the world, and his upcoming super fight against Conor McGregor has given the former boxing champion more reasons to brag about his bank account than ever.

In 2015, Mayweather’s long-awaited bout with Manny Pacquiao made the fighter known as “Money” well over $200 million. But during a recent episode of Showtime’s “All Access”, Mayweather claimed that he’ll make $300 million for his fight against the UFC’s lightweight champion. If that’s true, it’ll represent the largest payday of Mayweather’s entire career, and there’s a chance that this historic fight will top the $623.5 million in total revenue that Mayweather-Pacquiao generated nearly two years ago.

A large percentage of Mayweather’s massive payday will come from his cut of the pay-per-view profits. Very few know how much of the pay-per-view haul he’ll receive from this fight, but again, his fight against Pacquiao provides a good idea of what that number might be. For that bust of a boxing match, Mayweather and Pacquiao were left with a 60-40 split–in Mayweather’s favor of course, of what remained of $455 million in pay-per-view profits after cable and satellite providers took a combined 30-40 percent and HBO and Showtime split 7.5 percent.

Even if Mayweather-McGregor only matches that $455 million, Mayweather’s take of the pay-per-view profits this time around would easily exceed $100 million. When added to a purse that’s likely between $100 and $150 million, you can see why Mayweather isn’t so crazy for claiming that he’ll make over $300 million for fighting the Irishman.

And that’s not including the money Mayweather will make from his share of the revenue generated from the sale of tickets, food and beverages, merchandise, as well as what he stands to bring home from branding and sponsorship deals.

Recently, it was reported that Mayweather will make around $25 million from branding and sponsorship deals on fight night. That $25 million includes $1 million each for the right to advertise on Mayweather’s “victor’s cap”, weigh-in shorts, boxing shoes and robe. Over half of that $25 million is revenue generated from sponsors paying to advertise on a specific patch of Mayweather’s fight shorts, including $3.5 million each for the front waistband and “front side seams,” $2 million for the “rear top waist,” $3 million for the “rear center” and $1.5 million for the “rear thigh”.

Another $5 million of that $25 million will come just from ring sponsorships including the $3.1 million that a betting agent recently paid for the right to advertise on the ring cushion that will be behind Mayweather’s head on fight night.

Obviously, we can’t come to an exact number for Mayweather’s earnings without knowing the totals of fight night revenue from food and beverages, tickets and merchandise, or what his cut of that revenue is. But based on what we do know and information provided from Mayweather’s bout against Pacquiao, it’s safe to say that “Money” will easily make somewhere between $250 and $300 million for his final night in the ring.
