The kid may only be 12 years old, but last year for his role in the “Karate Kid”Jaden Smith pulled in more money than 90%  of all the adults in America!

TMZ recently obtained Jaden’s Karate Kid contract from June 2009 — back when he was only 10 — and according to the docs, his up-front fee was split into two installments … one for a whopping $900,000 and another for $100,000.

Not to mention the tiny tot’s back end deal, which was even more lucrative — since the film topped $150 million in the domestic box office, the young actor took home another $2 million bonus.

Based on several additional in-contract perks AND the astronomical success of the film, Jaden likely pulled in even more.

Sweet!
