What is the average NFL referee salary, and are refs paid more for the Super Bowl?

It's well known that the National Football League's star athletes make tens of millions of dollars a year. NFL referee salaries, on the other hand, are more elusive. Certainly, they earn considerably less than the players, despite the tremendous amount of pressure they're under to make game-deciding calls, that could influence the outcome of the 2024 Super Bowl. 

Referee pay is governed by a collective bargaining agreement between the NFL Referees Association (NFLRA) — the union that represents them — and the NFL.

The latest contract, signed by both parties in September 2019, is effective through May 2026, but is not publicly available.
