Ok, since you asked from a purely financial point of view, let me answer the same from a purely financial point of view.
Your salary right now is 10 lakhs. You will pay 30 lakhs, + lose 1 year of your salary in the process. So total investment would be 40 lakhs.
Now, the average salary in ISB is around 21 lakhs. Even if I consider that you fall in the 25th quartile, and the minimum salary (as far as I remember) is around 14-15 lakhs, you would end up with, say, 16 lpa.
That’s 6 lakhs more than your current salary. You would recover the total cost in less than 7 years.
Please note, I haven’t accounted for:
- Your increased market value that will lead to faster promotions and raises
- A degree from a premier college that will safeguard you from any future layoffs
- 1 year of learning from some of the brightest minds in the industry
- 1 year of spending time with some of the smartest people in the country.
