The 15-year-old Canadian actor will earn a base salary of $65,000 for his co-starring role in The Goldfinch, according to an article on Monday by TMZ.
Finn also can earn up to an additional $50,000 if the film based on the Pulitzer Prize-winning novel of the same name is a blockbuster.
The actor's overtime rate if filming exceeds planned dates is $4,333 per day, according to the contract that must be filed in court since he's age 15.
The contract also states that Stranger Things has top priority if The Goldfinch filming runs into production of the Netflix series.
Finn and his Stranger Things co-stars recently received pay increases of $250,000 per episode of season three.
Millie Bobby Brown, 14, reportedly will make $350,000 per episode.
Finn plays Mike Wheeler in the Netflix series that enjoyed breakout success with its first season.
The series also stars young actors Gaten Matarazzo, Caleb McLaughlin and Noah Schnapp and adult stars David Harbour and Winona Ryder.
Finn also had a starring role in the 2017 supernatural horror film It based on the 1986 Stephen King novel.
He also can be seen later this year in the drama Dog Days that follows a group of people in Los Angeles interconnected by their canine companions.
Dog Days also starring Nina Dobrev, Vanessa Hudgens and Eva Longoria is scheduled for release on August 10.
