The average NFL referee salary was $173,000 in 2013, and it is set to rise to $201,000 by 2019. Note that the NFL season only lasts about half the year, and for most NFL referees, refereeing is not their only job.
No idea. But the base salary range for NHL referees is $110,000 to $255,000 and $72,000 to $162,000 for linesmen. There is one particular NHL ref that is currently making $357,000 per year on his contract. Competition is HUGE (some say even more intense than it is to get on a team as a player) and is based on seniority and evaluations.
