Chloë Grace Moretz -- I Win Big Bucks If Denzel Puts Asses In Seats

Nobody's pulling for Denzel Washington's new action flick more than his young co-star Chloë Grace Moretz -- because she's on the verge of a six-figure haul that will make her one of the highest paid teens in Hollywood.

17-year-old Chloë -- who also starred in the "Kick-Ass" movies -- already took home a $400,000 payday for "The Equalizer" ... but according to the her contract she stands to make a ton more if the movie achieves a couple of magic box office numbers.

Since Chloë is a minor her deal has to be filed with the courts -- and TMZ obtained a copy ... which shows she'll get another $150,000 if the movie earns $100 million in the U.S. and Canada. Girl's got a shot -- after 2 weeks it's at $64 million domestically.
