My parents always fight and it's affecting me?

Well not to be rude if your dad respected yor mom he probably wouldn't treat your mom like he does and he may love her I get that but love should never hurt no matter what and even if you all had millions of dollars money would still be an issue it sounds like your dad is a controling person more than just the money thing but I don't know that for sure one thing you could try is when they are arguing about the money thing and your dad is being mean to your mom flat out ask him why he is treating her like that if you love mom like you should you wouldn't treat her like that dad and mom doesn't treat you like that dad so stop it dad
