Thanks for the A2A.
You’ll definitely earn more than 5 LPA if you were to graduate from ISB.
ISB has a starting limit that companies coming to ISB for placements, have to adhere to and I can say from experience, the starting limit is way above 5 LPA.
ISB fees are around 33–34 Lakhs.
So, depending on the loan amount and thereby, the EMI, you can repay your loan between 5–10 years. It can even be much sooner, depending on the career moves you’ll plan and the associated salary hikes you are likely to get, once you graduate from ISB.
Hope this helps.
