What is Return on Investment?A performance metric called return on investment (ROI) is used to assess an investment's effectiveness or profitability or to compare the effectiveness of several distinct investments. ROI is to quantitatively assess how much money is earned in relation to the cost of an investment.
ROI is determined by dividing an investment's return (or benefit) by its cost. As a percentage or ratio, the outcome is shown.
Because ROI is expressed as a percentage, it is simple to compare to returns from other investments, allowing one to compare a range of investment kinds against one another.
Thus, return on Investment is the cost of investment.
