Average Scheme Delivery Margin (%) reflects the mean profit margin achieved across the total gross development value of a completed property development project. In property development finance UK, this figure provides a clear view of overall scheme profitability after accounting for construction costs, professional fees, finance costs, and sales expenses. It is calculated as total scheme profit divided by total scheme revenue, expressed as a percentage. This measure helps developers, investors, and lenders benchmark performance against industry norms and assess whether the delivered margin aligns with risk exposure, market conditions, and initial feasibility targets.


This sits beneath Project-Level Profitability, introducing a more specific variant of the measure without changing its core interpretation. It is commonly considered alongside Gross Development Margin on GDV (GDM), as both are closely related measures used to assess similar aspects of performance or risk.
