Earnings Premium
The additional income a college graduate earns compared to a worker with only a high school diploma, measuring the financial value added by a degree.
Detailed Explanation
The earnings premium, also called the college wage premium, measures how much more college graduates earn compared to workers with only a high school diploma. On average, bachelor's degree holders earn about 75% more than high school graduates over their careers, translating to roughly $1.2 million in additional lifetime earnings. However, this average obscures enormous variation by field of study, institution, and individual circumstances. Engineering and computer science graduates may earn 150-200% premiums, while graduates in some humanities and arts fields may see premiums of only 10-20%, sometimes not enough to justify the debt incurred. CollegeROI weights the earnings premium at 20% in the ROI Score, comparing program-specific median earnings to the median income for 25-34 year-olds with a high school diploma (approximately $30,000-$32,000 nationally). A negative earnings premium, where graduates earn less than the high school median, is a serious red flag and results in a significant ROI Score penalty. The earnings premium also varies by geography: degrees that command large premiums in major metropolitan areas may offer smaller advantages in rural regions.
