No. 4: Arrowhead Stadium
Team: Kansas City Chiefs
Fan cost index: $396.02
Arrowhead Stadium opened in 1972 but underwent a $375 million renovation that was completed in 2010. It has 76,416 seats, 4th highest in the league. And best of all, it doesn't cost much for one of those seats. An average ticket costs $68.38, while a premium seat costs $202.25. Both tickets are well below league average.
Frugal football fans will find deals inside the stadium, too. Game programs are free, and soda and beer are $4.50 and $7.25, respectively.
