In this lesson from Yale's Creating Change through Social Entrepreneurship course, students are introduced to a simplified financial template for quantifying a social venture's path to financial viability. The lecture walks through how to translate revenue assumptions, costs, and operational efficiencies covered in earlier lessons into a working financial model that shows a venture's route from revenue to profit or sustainability. As a practical tool building lesson, it consolidates the course's earlier material on revenue models and operational efficiency into a single applied exercise students can use to plan their own venture's finances.
