Yes, if you're good and that's what you want to do. I know someone who knows someone who went to UC Irvine (not one of the top 10) and got a $40,000 signing bonus, which on average wipes out a UC Irvine MBA's outstanding debt.
If his tuition costs were an additional $40,000, you would need a $120,000 (plus any gains that could be accumulated from that $120K) bonus to recoup the expenses. Not to mention that if you really are good, you probably would have made far more than minimum wage during those four years, so we could probably assume, even conservatively, $150-$200,000 for the real cost of the education.
Can a graduate expect to earn $200K more in the all important early stage of the career† over someone who is equally skilled and connected without a degree?
† Early stage being the most important time to collect due to the rules of compounding interest. An extra $200K made in the last year of your career is far less valuable.
Virtually all full-time MBA programs are two-year programs.
Here's an example of the math a prospective MBA student might consider:
Current cash comp (incl. bonuses) = ~$120k/year
Length of program = 2 years
------------------------------
Total expected comp lost for next two years = ~$240k (figure $160k after taxes)
Tuition = ~$60k/year
Living expenses = ~20k/year
------------------------------
Total two-year costs = $160k
Internship earnings est = $20k
------------------------------
Total two-year net impact = ~$380k ($300k after taxes)
(Note that this doesn't factor in things like student loan interest)
Some things are more important than money. I enjoy learning new things as much as the next guy, so I often value education above income. However, I am not sure it is a wise choice if money is your only motivator.
