The Most a brain surgeon should strive for making is around $750,000 a year. So, basically, you make $600,000 after taxes. That is if you are really good. If you are mediocre, you can and would probably make $350,000 - $450,000. If you are very selective or you are lazy, but do a decent job, you make $250,000 a year. You will have lots of medical schooling bills, but only if you don't become something first and you only want to be a brain surgeon.
