Return on Investment (ROI)

Return on Investment (ROI) is a performance measure used to evaluate the efficiency of an investment or compare the efficiency of several different investments. To calculate ROI, the benefit (or return) of an investment is divided by the cost of the investment. The result is expressed as a percentage or a ratio.

The formula is typically written as: ROI = (Net Profit from Investment / Cost of Investment) x 100. The "Net Profit" component can be calculated in various ways, but it often represents the gross profit from the investment minus its associated expenses. The "Cost of Investment" can include initial Capital Expenditures (CAPEX) as well as ongoing operational costs depending on the analysis.

ROI is a critical Key Performance Indicator (KPI) for assessing past investments and for forecasting the potential returns on future ones. It provides a straightforward measure of an investment's profitability, helping finance teams and business leaders make informed decisions about where to allocate resources for maximum financial gain. It is a foundational element in building business cases for new projects and evaluating the performance of different business units or initiatives.
