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.
by 2019 nfl refs will make $ 200000 per year for refereering maybe 20 four hour games per year probably the refs have to go to some classes and training so maybe it s $ 200000 for what amounts to a few weeks of work still these guys have other full time jobs
