See How much Referees are earning in Top Leagues in Europe

Depending on the level, referees can earn a little or a lot for officiating a match. Amateur referees in the UK work on a game-by-game basis and their match fee is dependant on the local football associations. Pay is usually between £20 and £40 per game.
Referees at the semi-professional level - the lower leagues of the English football pyramid - get both their match fee as well as expenses. They are paid around £80 per game as well as whatever mileage they have to travel to and from the match venue.
At the top end, Premier League referees are salaried so they get paid a regular wage with match fees on top of that. Referees in the top-flight of England can earn as much as £70,000 per year. They are paid a basic yearly retainer of between £38,500 and £42,000 based on experience, and then are paid £1,150 per match on top of that.
Championship referees receive the same basic yearly retainer but are only paid £600 per game.

How much do refrees earn abroad?

Unlike in England where referees are paid a basic yearly retainer and then paid per-match on top of that, the officials in the rest of Europe's top leagues are just paid on a game-by-game basis.
La Liga games provide the higest match rate, with referees paid €6,000 a game - which works out at around £5,200. France and Germany's top-flight referees get paid just over half that amount.

Champions League referees are divided into tiers depending on their experience, and thus the more senior officials are paid over £5,500 per game if they are in the Elite tier. Elite Development referees get £3,800, while the bottom tier ones get £700 per game.
