I can give you an idea about the cost of doing an MBA from NITIE as one of my friends is a student there. At present, the tuition fee for MBA is 11 lakhs for a period of 2 years.
Other than that, if you consider assuming Rs. 3500 as the average mess fees for a total of one month, then it sums up to Rs. 35,000 for a time period of 10 months (considering 2 months of vacation period).
The mess fee sums up to Rs. 80,000. The overall amount you might personally require can be 1 Lakh in a total of 2 years. Thus, it can possibly be around or over 13 Lakhs, if you go on to plan for a rather controlled cost vacation in NITIE.
