what is return on investment (roi)? 

Return on investment or ROI is a measure of the efficiency of your investment. In other words, how much did you get back after investing in a certain area and how many years do you need that return to finally make a profit.

Here's an example:  
Invesment
Return every year
ROI
From which year will it start making a profit?
Rs. 1 lakh
Rs. 25,000
25 percent
From 5th year

how's education and roi linked?

An education is a big investment and your ROI starts when your son/daughter starts earning after finishing a course and getting a placement through the college. We will try to give you a rough idea about which college and what course gives you what kind of ROI.

Here's another example:
Total education cost (4 years for B.E.)
Average salary for that course/college
Return On Investment (ROI)
Rs. 10 lakh
Rs. 3 lakh/year
30 percent
ROI can also be a range (example: 30% - 40%) depending on courses or colleges if the cost for studying a particular course in various colleges varies wildly.
 
You need to be aware that these calculations are estimates based on various volatile numbers. We take the averages of various numbers to give you an idea of a potential ROI to make an informed decision. We are in no way responsible for any decision that you make based on these numbers.
