This is the month when I receive the maximum phone calls or emails or whatsapp messages. Students and parents are confused between various programs and if you ask them for the source of confusion, it is almost always, which program has a marginally higher RoI. I wrote a blog last year on Return on Investment in Education where my thesis was that one should try to figure out what people are doing 5-10 years after graduation and not worry about the first month salary after the graduation. But I think it was a bit complex and talked about too many things. Still if you want to understand RoI thing in more details, do read that.
In this blog, I will take a simple example to show why considering just the first month salary is not a good way to consider RoI. By the way, I am of the opinion that one should never look at RoI in these terms, and should just consider the quality of education in a university, and hope that higher quality education will lead to a good career. But since I can't convince people to not look at fake placement data, let me take a small step and point out some obvious fallacies.
Let us start with the question. You have options to take admission in two different programs. The program 'P1' has the total cost over 4 years as Rs 10 lakhs and the median salary offered last year to graduating students was Rs. 50,000 per month. The program 'P2' has the total cost over 4 years as Rs 20 lakhs and the median salary offered last year to graduating students was Rs. 60,000 per month. Which one would you choose.
The typical answer I have received is that P1 has the payback period of 20 months, and P2 has a payback period of 33 months (just divide the total cost by first month salary), and hence P1 is obviously far better.
Let us do some maths now. But before that, let us make some assumptions. One will work for 50 years. OK, let us say 40 years. That the average growth rate in salary per year will inflation plus 5% (an extremely conservative estimate). Now, let us look at what does an additional investment of Rs. 10 lakhs give us:
First year, an additional Rs 1.2 lakhs and every year, this number increases by 5% at constant prices. So in 40 years, you will earn an extra 1.45 crores. Remember this is at constant prices and over and above inflation. There is no investment in the world that can beat this or come even close. And this is when we had taken an extremely conservative numbers. Just to compare, an investment at 10% (remember, we are discounting inflation in all our calculations), will give you 1 lakh per year for 40 years, that is 40 lakhs in 40 years. (I am not assuming reinvestment, but consumption, but it would not make any difference to the point.)
Now, if we assume that P1 is likely to be poorer quality and P2 is likely to be higher quality and that is why P2 is able to command a higher price, there will be an additional effect. People with P1 may grow at 5% (plus inflation) but people with P2 degree may grow at 7% (plus inflation). Better quality education also has other side effects in terms of taking better decisions in life.
The summary is that if a higher cost program results in even a small increase in placement, it is a better RoI for you. (Again, a statutory warning to nor consider RoI but quality of faculty, personal interests, curriculum, while taking the decision regarding higher education.)
