According to Inside Jobs and the CIA website, agents can make anywhere from $52,000 to $81,000 per year as of 2014. As with most other jobs, the more special skills, education and experience an individual has, the more that person can make.
CIA agents are responsible for protecting American citizens. Sometimes, that is done on the home front by catching murderers, cyber criminals and other types of terrorists. Other times, protection happens in remote locations by protecting citizens abroad, or just being the eyes and ears the country needs to be ready. An agent's job encompasses many duties, and sometimes it's dangerous work. An agent's pay may reflect that.
The two biggest factors that influence an agent's pay include level of training and the location of the position. For example, an entry-level agent working in an office in Washington, D.C., is going to make less than an agent who has been on the job for four years and located in the middle of a war zone. The Bureau of Labor and Statistics predicts that the wage in this field will grow on average with other fields. One way an individual can improve his or her chances of getting in is by learning foreign languages.
