You fail to say what you earn and how many kids you are supporting.? You have to pay 20% of your net income as defined by Illinois law for 1 and 28% for 2 children. If 160 equals that amount, then you are not paying too much. If it is too much you need to file a motion seeking a downward adjustment.
