Designated players like Tim Cahill, Robbie Keane, Landon Donovan, Thierry Henry are the most expensive goal-scorers in the league - costing their respective teams at least one-quarter of a million for each goal they have scored, so far this season.
Furthermore, of those elite 4, only Henry has more than 3 goals, while on the other end of the scale, Adam Jahn's (4 goals) and Jack McInerney (7 goals) set their teams back less than $10k for each goal they have scored this season.
For further analysis, I include value for providing assists - 2 assists is worth 1 goal - an arbitrary amount but one that is designed to give credit for the play maker as well as the finisher. Here you can see that, with 1 assist, the defender Doneil Henry is paid a cool half-mill. To be fair, defenders are not paid for assists, but midfielders are.
Tim Cahill looks a little more affordable (at $320k for goals and assists) for New York but there are some very affordable options out there. Houston, for example, pays Will Bruin less than $8k for his 4 goals and 3 assists, while Graham Zusi earns slightly more than $10k for his 3 goals and 4 assists.
If you are interested in the math - I take the player's total salary and divide by percentage of games played for the season (or the 90 minute equivalent) and then divide that by the number of goals scored to date. For the goals and assists calculation, it is the same, but I divide assists by 2.
For example, if a player earns $100 for the season, and has played 17 games out of a 34 game season = 100 * (17/34) = $50. This means the player has been paid $50 to date for his playing time. If he has scored 1 goal = $50/1 goal. If he has scored 5 goals = $50/5 goals, this means he earns $10 per goal.
If the same player has scored 1 goal and 2 assists, he earns:
$100 * (17 games played/34 total games in season) / 1 goal + (2 assists/2) = $50 / 1 + 1 = $25 per goal and assists.
