It is true that $170-180K is a big amount and repaying that is not very easy. In my case, fortunately I have received $30K scholarship and that reduced the total cost to $140K.
Even then it is a lot of money. From my prior savings and summer internship savings I could raise $25 K and some amount of money from my family. Net, net I have less than $100k loan and the loan has been arranged entirely by the Booth school with out any surety. If I don't live ostentatiously, it will take me less than 2 years to repay the loan.
But, each case is unique. It depends on whether you get a scholarship and how much and even more importantly whether you get a good job and in US or other such places with high savings potential.
Most people do get fairly good jobs after graduation, most of them in US (
I am referring to the case of Indians from Booth school. I presume, it must be equally good with other top schools). In all such cases, I think the loan could be repaid in 2 to 3 years, provided the loan is not much more than $100K. I am sure every one will have some savings and can save some amount from summer internship.
But I do know one or two stray cases of people struggling to find a good job after graduation. In such an event, the loan can be very onerous. But the probability of such an occurence, in my view, would be less than 5%.
It will also depend on your past background. If you are a strong candidate, to begin with, you are likely to get a scholarship and a very good job on graduation.
But if you are borderline candidate who happened to scrape through the admission process, then the risks are more. As I mentioned in my previous posts, people with prior US education and experience or if from India, if they worked in companies like Mckinsey, Goldman, JP Morgan etc. prior to their doing the MBA, then they are not likely to have much of a problem in finding a good job.
Net,net, if you have to take a loan of $100K or less, I think it is worth taking the risk, in most cases. But, if you want to finance your studies entirely through loan, that would mean $150K or more and that increases risks. But some people may still find it worth while! But I would be a little more worried to take on a $150K loan. Since my loan was less than $100K, I felt that it was a risk I could take.
It also depends on business cycles. Just now the business cycle seems to be improving and job scene is good.
