Weighted Average Cost of Capital (WACC) is a key financial metric in property development finance UK, reflecting the overall cost of raising capital for a project. It calculates the weighted average of the cost of equity and the after-tax cost of debt, proportionate to their share in the project’s capital structure. WACC allows UK property developers and financiers to assess required returns, evaluate investment risks, and compare financing options. A lower WACC indicates cheaper capital, enhancing project feasibility, while a higher WACC highlights more expensive funding and greater financial risk in development projects.


This sits beneath Weighted Average Cost Metrics, introducing a more specific variant of the measure without changing its core interpretation. It is commonly considered alongside Blended Gross Finance Cost Rate, as both are closely related measures used to assess similar aspects of performance or risk.
