Guide on Return on Investment (ROI)
Return on Investment (ROI) is a critical metric in project cost management under the broader concept of the capital asset pricing model (CAPM).
Why is it important?
ROI is crucial because it quantifies the profitability of an investment or project. It expresses the net benefit (profit or loss) as a percentage of the total investment to reasonably compare different investments. Further, it assists investors in making informed decisions.
What is Return on Investment?
It is the ratio between the net gain from an investment and the cost of the investment. The formula to calculate ROI is (Net Profit / Cost of Investment) x 100%.
How does it work?
A positive ROI implies a profitable investment, while a negative one suggests a loss. A higher ROI percentage indicates higher profitability.
