While the median Football Bowl Subdivision institution spent about $50 million in 2010-11, versus $12 to $13 million, respectively, for the Football Championship Subdivision and schools without football, the research reveals a more consistent contribution from all Division I schools as the value they place on their athletics programs.
Fascinating! FCS schools pay less than 1/5 the budget, they actually also pay less than the budget at schools like Gonzaga's, St. Mary's, St. John's etc.

Other findings include that in 2010-11 for almost 1,100 NCAA institutions in all three divisions, only 23 (all in Division I) generated more revenue than their overall athletics expenses. That number has ranged from a minimum of 14 during the recent recession to a maximum of 25 over the past several years, including 22 in 2009-10.
This one is a well-worn stat, and has been consistent over the past decade, but it's notable that even with the explosion in TV revenue, these numbers are very constant. And you can probably guess who the schools are.. and they ain't UL-Monroe, Idaho, or Memphis.

There are other goodies in here, too:

Athletics spending also continues to represent a small percentage of overall university budgets – about 5 to 6 percent in the past several years. (When generated revenues are netted against expenses, the median percentage of athletics expenditures of total expenditures is less than 3 percent in the FBS.)

NCAA schools in all three divisions spent about $330 billion in 2010-11 educating their students. The $12 billion spent on athletics represents a little more than 3.5 percent of total spending. That shrinks to less than 2 percent when the $6 billion in revenues is factored into the equation.

There was an upward movement in median generated revenues for Division I institutions in all subdivisions from 2010 to 2011. Football Bowl Subdivision schools saw a 9.7 percent increase, while median generated revenues increased by 4.6 percent in the Football Championship Subdivision. The increase was 12.6 percent for schools without football.

Total expenses for the last year increased at a lower percentage than generated revenues for FBS, FCS and schools without football. The FBS median expenses increased 8.8 percent from the previous year. The increase was 1.0 percent at the FCS level and 3.2 percent for schools without football.
Think about those last two stats for a minute. FBS NET revenue only increased by 0.9% a year, while FCS NET revenue increased by 2.2% a year. FCS is growing faster than FBS, while costs are nearly 80% lower. There is plenty of good news for FCS in these statistics.
