Return on Investment

ROI is calculated as net profit divided by the cost of investment, typically expressed as a percentage, making it straightforward to compare the efficiency of different investments. It is one of the most widely used financial metrics across business functions, from marketing campaigns and capital expenditures to software purchases and training programs. While simple on its face, effective ROI analysis requires careful attribution of both costs and returns, which can be challenging for indirect or long-term investments. Understanding ROI helps stakeholders justify budgets, prioritize initiatives, and measure the tangible value of their decisions.
