What Is Business ROI and How Do You Calculate It?

Business ROI, or Return on Investment, compares the value an investment creates with the money spent to produce that result. A positive ROI means the investment generated more value than it cost, while a negative ROI means the investment lost money during the measured period.

Basic ROI formulaROI = (Net Profit ÷ Investment Cost) × 100
