Floyd Mayweather Jr. didn’t just make a truckload of money in his fight against Marcos Maidana, he made an obscene truckload of money.

Mayweather did the calculations and posted a photo on Instagram on Monday, saying that he’d made $32 million in 36 minutes with his majority decision over Maidana. Then he added that he stood to more than double that with the pay-per-view cut figured in.

It’s a nice chunk of change, but how much could he make for the fight everyone wants to see, the one against Manny Pacquiao?
