What is Return on Investment (ROI)?

Return on Investment (ROI) is a financial metric used to measure the profitability or efficiency of an investment by comparing the gain from the investment to its cost.

The standard formula is: ROI = (Gain from Investment − Cost of Investment) ÷ Cost of Investment × 100%.

ROI helps businesses and investors determine whether investments such as marketing campaigns, technology systems, equipment purchases, or business expansions produce returns that justify their costs.
