Social Value Bank

In performing SROI analysis, one key step is to map appropriate financial proxies with the social outcomes. This social value bank provides examples of these social outcome-proxies mapping and reference amounts of some financial proxies are provided. You can also try the SROI calculator.

As highlighted in the key concepts, there are in general two approaches in monetising social outcomes. One is the “Social Opportunity Cost” (SOC) approach and the second is the “Willingness-to-pay” (WTP) approach.

Social opportunity cost (SOC) approach

The following types of social outcomes can be monetized using the social opportunity cost (SOC) approach:
