Benefits and Costs of a College Education If an individual chooses not to go to college at age 18, he or she enters the labor market on leaving high school, and earnings rise and fall along the path labeled “High School.” The college student incurs the direct costs of education, such as tuition and books, and the forgone earnings of not immediately entering the job market. The benefits of the college education show up as the difference in earnings from ages 22 to 65.
