Development Margin on Cost is a fundamental profitability metric widely used in UK property development finance. It measures the expected profit of a project as a percentage of the total Gross Development Cost (GDC), calculated by dividing the profit by the GDC and multiplying by 100. This figure indicates how efficiently a development converts its overall investment into profit, providing SME developers and industry professionals with vital insight into the financial viability and feasibility of a scheme. It is particularly useful when benchmarking projects or negotiating funding terms with lenders, ensuring the potential returns adequately compensate for the development risks involved.
This sits beneath Project-Level Profitability, introducing a more specific variant of the measure without changing its core interpretation. It is commonly considered alongside Profit on Cost (POC), as both are closely related measures used to assess similar aspects of performance or risk. In funding terms, Development Margin on Cost is most commonly encountered in connection with Fixed Return + Profit Share within the property development capital stack.
