How much does Miley Cyrus make?

Factual Questions
1

Miley is the over exposed star of the Disney kid’s show, Hannah Montana. When I was out doing some Christmas shopping I saw her image, as Hannah, on just about everything. I was just looking for some items at an on-line furniture store and noticed that there is also a “Hannah Montana collection” for bedroom furniture.

So how much does she make in salary for the show, royalties for her album(s) and licensing deals for her image? Is she the wealthiest non-adult out there, at least in terms of her own money making ability? Or does Disney keep it all, sort of like when Greg Brady was a rockstar because he fit the suit?
