Return of investment is nothing but the amount of capital invested by a company or single person and what is the profit i.e return they get of that investment.
As a performance measure, ROI is used to evaluate the efficiency of an investment or to compare the efficiencies of several different investments.
The investment with the largest ROI is usually in the top prioritization,the spread of ROI over the time period of an investment should also be taken into account.
Risk with ROI usage
To use ROI as an indicator for prioritizing investment projects is very risky since usually the ROI figure is not accompanied by an explanation of its make-up.
As there are no proper reasons or explanations with the measuring results of roi it is quite risky.
One of greatest risks that comes with the traditional ROI calculation is that it does not fully “capture the short-term or long-term importance, value, or risks associated with natural and social capital” because it does not account for the environmental, social and governance performance of an organization.
