For example, social return on investment (SROI) is a principles-based method for measuring extra-financial value (i.e., environmental and social value not currently reflected in conventional financial accounts) relative to resources invested. Return on investment may be extended to terms other than financial gain. In a survey of nearly 200 senior marketing managers, 77 percent responded that they found the "return on investment" metric very useful. For a marketing ROI percentage to be credible, the effects of the marketing program must be isolated from other influences when reported to executives. Marketers should understand the position of their company and the returns expected. Marketing decisions have an obvious potential connection to the numerator of ROI (profits), but these same decisions often influence assets’ usage and capital requirements (for example, receivables and inventories). net present value): most textbooks describe it with a "Year 0" investment and two to three years' income. ROI is often compared to expected (or required) rates of return on money invested.

ROI and related metrics provide a snapshot of profitability, adjusted for the size of the investment assets tied up in the enterprise. Recently, the concept has also been applied to scientific funding agencies’ (e.g., National Science Foundation) investments in research of open source hardware and subsequent returns for direct digital replication. The investment with the largest ROI is usually prioritized, even though the spread of ROI over the time period of an investment should also be taken into account. It is also used as an indicator to compare different investments within a portfolio.
