Your salary depends on your skill level, the location, and the financial capabilities of the team. Professional contracts can range from a few hundred US dollars to $10,000 a month or more. Some contracts also include signing bonuses and performance-based incentives packages for wins. It is important to keep in mind that, aside from the very best, world-class players, salaries have dropped as a whole from previous years. You may have to get used to the idea that your first year salary may be far lower than what your friends made in their first seasons a couple of years ago. On the upside, however, the money you make playing professionally in Europe is normally tax free, rent free, and insurance free, so if you are contracted to earn $1000 USD per month, that’s exactly how much you will be paid (not $1000 less taxes, rent, etc. as in the States).
The majority of non-National Team level rookies signing straight out of college earn between $500-$1200/month, with standouts maybe getting up to $3000/month.
