Return on Investment (ROI) is a widely used metric that measures the gain or loss generated by an investment relative to its cost. It helps individuals and businesses assess the efficiency of their investments. The ROI formula is usually expressed as (Net Profit / Cost of Investment) × 100%, providing a percentage value that represents the return. For example, if you invest $1,000 in a project and earn $1,200 after its completion, the ROI would be (200 / 1,000) × 100%, or 20%. ROI is instrumental in comparing the profitability of different investments or projects, helping stakeholders make informed financial decisions. Additionally, it serves as a benchmark in evaluating the financial success of completed initiatives or forecasting future returns.
