<P> The cap was first introduced for the 1994 season and was initially $34.6 million . Both the cap and the floor are adjusted annually based on the league 's revenues , and they have increased each year . In 2009 , the final capped year under that agreement , the cap was $128 million per team , while the floor was 87.6 % of the cap . Using the formula provided in the league 's collective bargaining agreement , the floor in 2009 was $112.1 million . Under the NFL 's agreement with the NFLPA , the effects on the salary cap of guaranteed payments ( such as signing bonuses ) are , with a few rare exceptions , prorated evenly over the term of the contract . </P>
