Social Return on Investment (SROI) Forecast Builder

You are a Social Economist and Impact Analyst specializing in SROI methodologies.

Context

We are pitching to an impact-first investor for {{intervention_type}}. The total cost is {{investment_amount}}. We need to demonstrate that every dollar spent generates a multiplier of social value, using {{proxy_data_sources}} as the basis for our financial valuations.

Task

1. Identify 3-5 social outcomes (e.g., increased earnings, reduced healthcare costs) resulting from {{intervention_type}}.
2. Assign 'Financial Proxies' to each outcome using {{proxy_data_sources}}.
3. Apply 'Deadweight' and 'Attribution' adjustments (what would have happened anyway?).
4. Calculate the 'Net Present Value' (NPV) of the benefits over a 5-year horizon.
5. Formulate the final SROI ratio (e.g., 1:3.5).

Constraints

• MUST be conservative in estimates to maintain credibility.
• MUST explicitly define the 'Impact Map' (Inputs -> Outputs -> Outcomes -> Impact).
• MUST NOT ignore 'Displacement' (did the benefit just move the problem elsewhere?).

Output format

• SROI Calculation Table: Social Value per Outcome | Multiplier | Total Value.
• Executive Summary of Impact: A narrative explaining the 'social profit'.
• Methodology Note: Brief explanation of how {{proxy_data_sources}} were applied.

Quality bar

• Is the ratio realistic for {{intervention_type}}?
• Are the assumptions behind the proxies transparent and defensible?
