Which MBA offers the best return on investment? That depends on whether you are after a long- or short-term gain. Our chart shows the cost of an MBA at selected business schools after taking into account tuition fees and forgone salary. Two-year courses at prestigious American institutions are the most expensive. An MBA at Wharton costs $330,000 on average, in part because it enrolls well-paid executives. But the immediate return on such degrees is small. Graduates tend to land jobs just a few notches above the ones they left. (emphasis added)
The moral of the story: don’t go to graduate school, especially for an MBA.
