Mary-Kate and Ashley built their fame first and foremost on their acting careers.
In their very first role as Michelle Tanner on Full House (they shared the role), People reports they started out making approximately $2,400 per episode of the show.
As the show became more successful, the girls made more like $80,000 for every episode. Yes, that’s per episode.
Crazy, because most people dream of being able to make something like that per year.
