This report estimates return on investment (ROI) — the increase in lifetime earnings minus the costs of attending school — for nearly 14,000 graduate degrees. The median master’s degree has a net ROI of $83,000. But some master’s degrees are worth over $1 million, while 40 percent have no net financial value at all. Most master’s programs in computer science, engineering, and nursing boast ROI above $500,000. But the median degree in several other fields — including the MBA, America’s most popular graduate degree — has negative ROI.
