#### What is the return on investment (ROI)?

“Return On Investment (ROI)” is a measure of performance that is used to determine the productivity or efficiency of an investment or to compare the productivity of multiple investments. ROI directly measures the return on a particular investment relative to its cost. To calculate ROI, the return or profit of a particular investment is examined in relation to its cost.

Also, the rate of return on investment can be calculated by dividing the return on an investment by the cost of doing so.

`return on investment (ROI) = Profit rate ÷ Cost rate` According to the above formula, for example, if the cost of a project is equal to 10,000 $ and the amount of profit obtained from it is equal to 10,000 $, the return on investment will be equal to 1 unit or 100%.
