ROI, or return on investment, is a common business term used to identify past and potential financial returns. Managers and executives look to the ROI of a project or endeavor because this indicates how successful a venture will be.
Return on investment (ROI) is a financial ratio intended to measure the benefit obtained from an investment. Time is usually of the essence in this measurement because it takes time for an investment to realize a benefit. An ROI calculation can be illustrated by the purchase and subsequent sale of a house.f that income is factored in, the net benefit will be $64,000 rather than $40,000, and the ROI will be 64 percent. The general rule to keep in mind is that ROI is the ratio produced when all gains from a transaction, less the costs associated with that transaction, are divided by the initial investment.
