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.
But compared to the players, referees are earning less than minimum wage. The average NHL player salary in 1970 was $18,000; Buffey was making $12,000 two years earlier as an official.The average player salary in 2011-12 was $2.4 million in the NHL ... so yeah, there's a larger disparity between the players and those officiating them now than in 1968.he referees make between $110,000 to $255,000 each year. The linesmen earn between $70,000 to $162,000 per year. The average pay for a referee is between $115,000 to $255,000 each year.
