Massachusetts colleges and universities offer a good return on investment, according to a new report from PayScale Inc., a Seattle-based data firm.
Seven Massachusetts colleges ranked in the top 50 nationally, and Babson College in Wellesley finished at number one for business schools nationwide, and 25th overall.
PayScale ranked more than 1,500 undergraduate programs based on how much graduates are projected to earn over a 30-year period, after subtracting the cost of their degrees.
The report took into account such expenses as tuition, fees, room, board, books, supplies, and wages students might earn if they enter the workforce immediately after high school instead of going to college. The calculations did not include financial aid. Full story for BostonGlobe.com subscribers.
