Perry's high performance this year was due mostly to her Prismatic World Tour, which grossed more than $2 million per city over the course of 126 shows--75 of them were overseas. She reportedly also drew in $20 per head in merchandise sales. That's a lot of Katy Perry shirts.

Her deals with brands like Coty, Claire's and Covergirl also helped her score big this year. And with a new Perry-themed mobile game due out this fall, she's bound to score big next year too.
