Per Celebrity Net Worth, Cory Monteith's net worth at the time of his death was $2 million. Of course, "Glee" had a big role to pay in Monteith's success and subsequent wealth, but he'd also had some larger roles in other projects too. He starred in the movies "Monte Carlo" and "Sisters & Brothers" in 2011, and was also involved in the films "All the Wrong Reasons" and "McCanick," which were both released posthumously (via IMDb).
The actor hadn't always found things easy, using alcohol and marijuana from the age of 13 (via Parade) and had attended sixteen different schools by the time he dropped out at 16. Living with addictions, the actor turned to petty crime to fund them (via HuffPost), until his mother and his friends encouraged him to attend rehab at the age of 19. Four months before his death, he was confirmed to have entered a treatment facility for substance addiction, and was written out of the end of the fourth season of "Glee" as a result, but was promised by co-creator Ryan Murphy that he would still have a job upon return (via The Hollywood Reporter).
