Social Return on Investment

Also Available In: Español

Social Return on Investment (SROI) is a systematic way of incorporating social, environmental, economic and other values into decision-making processes. By helping reveal the economic value of social and environmental outcomes it creates a holistic perspective on whether a development project or social business or enterprise is beneficial and profitable. This perspective opens up new opportunities and forms the basis for innovative initiatives that genuinely contribute to positive social change and poverty reduction for all. SROI balances proving and improving or addresses the paradox between accountability and learning by placing the perspectives of the different stakeholders at the center of the valuation process.

​SROI originated in the USA from social enterprises interested in new ways to value the contributions they were making to society. It later arrived in Europe, where there is an increasing interest in the methodology as noted by recent publications by Context international cooperation in the Netherlands, the New Economics Foundation in the UK and Social Value UK.

SROI is used for planning purposes in terms of designing a Theory of Change, or Business Plan, and for assessing to what extent impact is realised or changes need to occur in the Business Plan. Although the SROI approach supports the thinking along the lines of a result chain, it does not support the idea of the components being connected in a linear fashion. The SROI approach is embedded in the acceptance of development taking place in situations of complexities.

Here is a simple, illustrative example: A project aims to uplift the standard of living of people in a certain area and a beekeeping initiative is set up. As a result a beekeeper now enjoys regular meals whereas before this was not the case. In traditional Cost Benefit analyses, the value of the lunch would be measured in market prices. However after interviewing the beneficiaries, and applying some valuation tools, it turns out that the ‘real’ value is much higher than the market price; social value has been created above the market / economic value which is now being accounted for. 

Like traditional cost-benefit analysis, SROI includes a ratio; in this case a Social Return on Investment ratio. Where in traditional cost benefit analyses the ratios would be used to compare different projects, the SROI ratio is much more seen as one element in explaining and communicating general progress of certain developments. The number itself is not seen as the end goal. It can be interpreted as aiding the narrative of this particular initiative. 

The aspect of stakeholder perspectives is essential in the SROI approach. It is precisely the value perspectives of the stakeholders (and most importantly the key beneficiaries), assessed, not by assuming these values, but by thoughtfully and intellectually engaging the stakeholders themselves, which is at the heart of this innovative (e)valuation approach.

Linkages with other approaches and options

How is it done?

There are different components that are followed (not necessarily in a linear or chronological order) which collectively constitute the SROI approach.

A. Defining the boundaries (objective and scope). Depending on the nature of the project, programme or initiative, a specific geographic area will need to be chosen. For example it could be a value chain of a certain commodity, which would include a range of actors in a specific geographic area, over a time span of five years.

B. Identification and selection of key stakeholders. With a selection of key actors and use of participatory tools such as an ‘influence-importance matrix’, all relevant actors are identified who either will be affected by the activities within the scope or who influence the project (either positively or negatively).

C. Developing the Business Plan / Theory of Change. Representatives of all stakeholders (diversity is good) create the theory of change or business plan. This will enhance collective ownership and encourage learning from and about different perspectives and realities. It above all provides clarity regarding the key actors for whom the intention is to create value; reduce poverty, improve health, etc. This is one of the most important steps within the SROI framework: it tells the story of how stakeholders were (are) involved in the project and their perception and belief of how their lives have changed or will change.

D. What goes in (identifying inputs for each outcome) and what comes out (identifying results). For each intended outcome there are different investments or ‘costs’ linked to the realisation of the specific outcome. There may be unintended outcomes (or investments), which can also be measured; these can be positive or negative. Semi-Structured Interviews are conducted to identify benefits (see) and investments.

E. Valuation is the process of developing indicators to turn the articulated benefits and costs into a monetary value. Some benefits and costs are easy to valuate, for example when an intervention saves time, which can be used for productive work. Other benefits, like a higher status in the community are more difficult to attach a value to. Different tools can be used for this, including value ranking, use of opportunity cost, etc.

F. Calculation of the SROI ratio. By calculating the SROI ratio a comparison is made of the investments (inputs) on the one hand and the financial, social and environmental returns (outcomes and impact of an intervention) on the other. To enhance rigour in the ratio and credibility, it is most important that good solid research data has been used, as well as the best possible estimates of deadweight and attribution. This is generally seen as difficult (also by all other evaluation approaches and methodologies). However, through semi-structured interviews compared with other research data, approximates can be arrived at.

G. Narratives are increasingly understood as the stories that complement the numbers (ratio). They provide the context by which for example the ratio would be used. The narratives also reflect on what cannot be captured in the SROI ratio.

H. Verification is done throughout the analyses, either using triangulation or through other means. Verifying the stories / narratives as well as the quantitative data from different stakeholder perspectives is an important aspect of the complete analyses, as it further builds and maintains the trust and collective ownership of the initiative and approach.

By going through all these stages and collecting both qualitative and quantitative data, an SROI report can be created, which provides the opportunity to communicate to all stakeholders (actors) of the initiative, including managers, primary actors, funders, etc. Following the learning approach this report can be used for the next stages of development and for analysing and adjusting the business plan or elements thereof.


  • SROI can be integrated in existing M&E approaches and does not need be an add-on activity. In fact the approach could guide a participatory development model, with reflection and learning as consistent ingredients.
  • The approach has the capacity to create awareness of mutual interdependence and as such develops collective ownership and commitment. 
  • It leads to mind-shifts, for example from a perception of cost (with consequently negative associations) to the realisations that they should be seen as investments with clear results benefitting the community, individuals and households.
  • Rather than positioning initiatives within imperatives such as profit maximisation and neoliberal economic growth, SROI, allows actors to create opportunities to more directly address the creation and measurement of social value.

Critical success factors

  • The approach as described above requires knowledge of participatory options and tools and excellent facilitation skills in multi-stakeholder processes. A safe and conducive environment is required for dialogues and learning amongst a diversity of actors (with often conflicting interests).
  • For SROI to be successful as an approach, good data needs to be available. Very specific data on production technology, market price fluctuations, environmental risks, etc. may be required.

Thank you the page contributors. Social Return on Investment (SROI) is increasingly gaining interest particularly within the Third Sector. It offers an opportunity to account for broader benefits of interventions that would otherwise not have been estimated or valued.

A previous review identified some strengths and limitations of SROI approach. Like the author pointed out, availability of good data for SROI analysis cannot be overemphasised. This is critical for success. In a systematic review focused on the application of the SROI methodology in public health, similar conclusions were drawn. The authors of this systematic review also concluded that best practices such as analysis involving only beneficiaries (not all stakeholders), providing justification for discount rates used in models, using purchasing power parity equivalents for monetary valuations and incorporating objective designs such as case–control or before-and-after designs for accounting for outcomes will improve robustness of public health SROI studies.

In the post-2015 era, when global interest is shifting to subjective wellbeing and need to account for value-for-money of interventions, SROI may offer an opportunity for researchers, M & E specialists and policy makers to evaluate interventions in a holistic and participatory fashion. However, in my opinion, the approach is still growing and clearer guidance and consensus on how best to conduct SROI analysis are needed in moving forward.

Thank you for sharing your thoughts on SROI. It was really informative.

As mentioned, Social Return on Investment (SROI) is a methodology that aims to do just that, assigning monetary values to change being created by the activities of an organisation.
Impact organisations increasingly need integrated solutions to their impact data management needs. Social Return on Investment impact accounting demands an even more refined data management approach to ensure transparency and accurate execution of the approach. Implementing proper monitoring systems, communicating accurate reporting of impact, and weathering the high cost of SROI execution limit organisations’ ability to successfully adopt the SROI way.

There are several tools which can be used to calculate SROI easily. Some of the tools are Sametrica, Sinzer and Impact Cloud.
1. Sametrica is a reasonable solution for organisations seeking to take the first step into impact management from an SROI perspective. Where it falls short is its inability to house and manage different types of data -- it is really a solution for organisations oriented towards survey data.
2. Sinzer offers similar features as that of Sametrica, which focuses on leveraging survey data and an SROI approach.
3. The SROI methodology demands a fairly comprehensive approach to impact accounting. Sopact's SROI tool is a more comprehensive solution to that’s nestled within Sopact's Impact Cloud, integrated with its powerful data collection and data management applications. It is also a certified platform by Social Value International.

SROI offers organisations a comprehensive approach to understand and communicate impact returns, both internally and to potential funders. Assigning monetary values to social returns provides a shared language to better inform decision making across the stakeholder ecosystem. If implemented properly, SROI can definitely help in producing favourable outcomes.

The below blog gives more details about the tools to calculate SROI.
