What Factors Go Into Calculating Social Return on Investment (SROI)?

Social return on investment (SROI) is a method for measuring values that are not traditionally reflected in financial statements, including social, economic, and environmental factors. They can identify how effectively a company uses its capital and other resources to create value for the community. While a traditional cost-benefit analysis is used to compare different investments or projects, SROI is used more to evaluate the general progress of certain developments, showing both the financial and social impact the corporation can have.

How Social Return on Investment Works

SROI is useful to corporations because it can improve program management through better planning and evaluation. It can also increase the corporation’s understanding of its effect on the community and allow better communication regarding the value of the corporation’s work (both internally and to external stakeholders). Philanthropists, venture capitalists, foundations, and other non-profits may use SROI to monetize their social impact, in financial terms.

A general formula used to calculate SROI is as follows:

$\begin{aligned} &SROI = \dfrac{SIV - IIA}{IIA \times 100\%}\\ &\textbf{where:}\\ &SIV = \text{social impact value}\\ &IIA = \text{initial investment amount}\\ \end{aligned}$​SROI=IIA×100%SIV−IIA​where:SIV=social impact valueIIA=initial investment amount​

Assigning a dollar value to the social impact can present problems, and various methodologies have been developed to help quantify the results. The Analytical Hierarchy Process (AHP), for example, is one method that converts and organizes qualitative information into quantitative values.

While the approach varies depending on the program that is being evaluated, there are four main elements that are needed to measure SROI:

• Inputs, or resources investments in your activity (such as the costs of running, say, a job-readiness program)
• Outputs, or the direct and tangible products from the activity (for example, the number of people trained by the program)
• Outcomes, or the changes to people resulting from the activity (i.e., new jobs, better income, improved quality of life for the individuals; increased taxes for, and reduced support from, the government)
• Impact, or the outcome less an estimate of what would have happened anyway (For example, if 20 people got new jobs but five of them would have been hired in any event, the impact is based on the 15 people who got jobs directly as a result of the job-readiness program.)
