Good stuff.

It's sort of amazing, the range of return on investments for these schools. For instance, at the top school (IMD,) graduated students can plan on, over the five years after graduating, raking in $230,000 after MBA fees.

At the bottom of the list is HEC Montreal, where the 5-year ROI is only $46,000.
