The wages for each player in Hattrick are calculated using the player's skills. Wages are updated at the start of each season, at the same time that the players turn a year older.
A players main skill is the single most important factor for his salary. The salary will be 500 € plus a certain amount based on his skills and age. When a player reaches 27 years of age, his salary starts to decrease. Players who are playing out of their home country cost their clubs an extra 20%, which at higher levels can amount to several thousand €.
With training, it is possible to overtrain a player, so that his wages become astronomically high. Many National Team players have wages of several hundred thousand euros each week, and the best players are over the 1 million euro per week mark. Many of these are trained by farm teams who operate solely to support one NT player.
Transfer market wise, these players are generally worth less than players with slighty lower skills, due to their enormous wages.
