Example #3
Suppose an investor invests $1000 in the bakery in 2015 and sold his stock in 2016 at $1200. Then, ROI Formula will be as follows:
ROI _{Bakery }= (12001000) * 100 / 1000 = 20%
He also invested $2000 in the shoe business in 2015 and sold his stock in 2016 at $2800 then ROI Formula will be as follows:
ROI _{Shoes_Business }= (28002000) * 100 / 2000 = 40%
