What is Return on Investment (ROI)?

As the name suggests, ROI or Return on Investment is the premium or return earned on the money invested in the business. Hence, the name Return on Investment.

ROI is part of the profitability ratios. The profitability ratio helps in ascertaining the profit earned by the business during the year using different formulas. These formulas include:

  • Gross profit ratio
  • Net Profit Margin
  • Operating Ratio
  • Price-Earning Ratio

The formula used for ROI is given below:


The scene mentions an investment of Rs. 10 crores or 10,00,00,000 in the reality show. Returns or profits that Rahul talks about are approximately 400%. So the ROI can be calculated as below:

Profit = 400/100*10 crores= 40 Crores

ROI= 40/10*100= 4%

Gross profit ratio (GPR):

This ratio indicates the portion of each rupee of sales above the cost of goods sold. GPR generally varies for different industries. For example, the average GPR for the retail industry is close to 42.53%, for the software industry, it is close to 58%, and for the transport industry, it stands at 20%.
