Net Worth and Salary
As of 2025, A.J. Cook's net worth is estimated to be approximately $5 million. Her salary for "Criminal Minds" was $100,000 per episode in the early 2010s, which likely increased significantly over the years due to the show's popularity.
Beginning in September 2005, she starred as Jennifer "J.J." Jareau in the CBS drama Criminal Minds. On June 14, 2010, it was announced that her contract option would not be picked up for season six as a series regular reportedly due to budget cuts on the show, but she returned for two episodes to wrap up her character's storyline due to thousands of letters and petitions written to the show's producers. She also returned for one episode for the departure of Paget Brewster from the series. Former executive producer of Criminal Minds, Ed Bernero, later claimed that CBS executives called him one day and asked him to get rid of Cook and Brewster. Brewster also mentioned in a separate interview that someone from CBS called Bernero and said they wanted "new women" which led to their firing. She said that it was not due to budget cuts as their replacement was paid twice what they were paid. In April 2011, it was reported that Cook had signed to reappear for two more seasons of the show. In 2013, Cook and her Criminal Minds co-star Kirsten Vangsness managed to negotiate salary raises but not parity after years of being paid less than half the salary of fellow co-stars Matthew Gray Gubler and Shemar Moore. In 2017, both women held out on signing new contracts as they sought pay parity with Gubler. They eventually succeeded and closed new deals to return. Cook would continue to star in the series until it ended in 2020 after 15 seasons. After the show wrapped, Cook decided to take a break from acting and in 2022, she guest-starred on the show 9-1-1. It was also announced that she would be returning for the Criminal Minds revival.

Cook was declared legally blind in the second grade because of severe astigmatism, but wore contacts and thick "Coke bottle" glasses to correct her vision. Talking about her childhood, Cook recalled how other kids were "cruel" and that she "really couldn't see" and "everything looked like a smear of colour with no shapes". She also said that at the time of her diagnosis, she was not doing well in school. At first, people thought she had a learning disability because she could not read. In reality, she could not see the board, which affected her ability to recognize letters and know the sounds they made. In 2007, a surgical lens implant corrected the impairment.
After Higher Ground, Cook appeared in the 2000 TV movie The Spiral Staircase (alongside Higher Ground alum Kandyse McClure), and then captured leading roles in several films, including Out Cold (as Jason London's love interest), Ripper, I'm Reed Fish, and Final Destination 2.
