According to this article, USF's rent of the stadium is between $142,500 and $153,000 per game, depending upon how many butts are in the actual seats, and not just how many tickets are distributed. I'm not sure how much of the ticket money they receive, but I haven't read anything that suggests they get any money from concessions or any share of the parking revenues beyond the season ticket holder spots they are allocated.
"In lobbying for a stadium, USF will have to explain why a venue that's good enough for Super Bowls and a college football championship isn't good enough for the Bulls. USF pays the Tampa Sports Authority a fee of $142,500 for games when attendance is less than 24,000, and $153,000 per game when it's above that threshold."
