To identify the 50 top-ranked colleges and universities that pay off the least, 24/7 Wall St. reviewed the median earnings of former students who received federal financial aid that are working and not enrolled in school 10 years after matriculation from the U.S. Department of Education, last updated in May 2019. We ranked the schools based on the average earnings as a percent of annual tuition and fees. We only considered schools from U.S. News & World Report’s 2019 rankings of the best national universities and liberal arts colleges, with the exception of U.S. service academies and universities for which data was not available. Tuition and fees data is for the 2018-2019 school year and also came from U.S. News & World Report. For public institutions, in-state tuition is listed.
