With the NFL playoffs underway — only four teams remain to decide who will play in the Super Bowl on Feb. 5 — MarketWatch took a look at whether or not fans get what they pay for when they watch their teams live.

We analyzed data from the NFL and ticket aggregator TicketIQ, a ticket marketplace for sporting events and concerts. TicketIQ has been releasing initial average NFL ticket values since 2013.

The Kansas City Chiefs, Cincinnati Bengals and Arizona Cardinals charged their fans the least to see a home win. Each team won 23 home games between 2013 and 2016 and their average ticket prices were $126, $157 and $180, respectively. The Chicago Bears are the only team that could be defined as the worst value: The team sells tickets at a relatively high average price ($363.06) and has a bad home win record.

As you can see in the graphic, all four teams remaining in the playoffs deliver what fans pay for. Fans who buy expensive tickets in Green Bay, New England and Pittsburgh have a greater chance of seeing a win. And though fans have paid less on average for Falcons tickets, they haven’t won as many games as the others since 2013.

This season, more fans throughout the league had the opportunity to see a win at home compared with last season. There were 147 total home wins in the 2016 regular season compared with 138 in 2015.

Of course, as the old MasterCard advertisements about experiences being “priceless” showed, it’s hard to put a price on the full experience of going to a game. But clearly teams think if they win more, or build a new stadium, that they can charge more.

Ticket prices in general have been increasing in the NFL. Of the league’s 32 teams, 22 increased prices between 2013 and 2016. A variety of factors affect ticket prices, but it seems that the teams with the greatest percent change in price either moved cities or added a new stadium.

Methodology: A team’s value was based on its relative position on the scatterplot to other teams with a similar amount of home wins and average ticket cost. Other than the visual evidence, the value could also be quantified by calculating the average cost to see a home win. The majority of teams didn't stray too far from the trend line and for that reason were classified as ‘pay for what you get’.
