The Economist magazine has a great calculator to estimate the added economic value of attending a particular university.  By developing a regression equation that uses a range of student, college and geographical data to predict the subsequent earnings of each graduate, one can easily search the table to find whether a particular institution is above or below the regression line, in other words, whether the college brings more or less economic gain than one would predict.
