ROI may stand for:

Return on investment (ROI) is the benefit to an investor resulting from an investment of some resource. A high ROI means the investment gains compare favorably to investment cost. As a performance measure, ROI is used to evaluate the efficiency of an investment or to compare the efficiency of a number of different investments. In purely economic terms, it is one way of considering profits in relation to capital invested.

Purpose

In business, the purpose of the "return on investment" (ROI) metric is to measure, per period, rates of return on money invested in an economic entity in order to decide whether or not to undertake an investment. It is also used as indicator to compare different project investments within a project portfolio. The project with best ROI is prioritized. Recently, the concept has also be applied to scientific funding agencies (e.g. National Science Foundation) investments in research of open source hardware and subsequent returns for direct digital replication.
