First things first: ‘Do people get in debt because of it?’ – When you take a loan, you get into debt.
Moving on, I believe you are asking about your chances of being able to pay off the loan on time, without defaulting.
With an average package at ISB which I assume would be north of 21-22 lakhs (haven’t checked the latest figures), you’d be able to pay off your loan comfortably in the next 7-15 years(depending on your tenure), if you simply pay the bank mandated EMI. Paying it off sooner will depend on your in-hand salary, financial planning and priorities, among other things.
