Weighted Average Loan Margin measures the blended cost of borrowing across multiple property development finance UK facilities by accounting for the relative size of each loan within the capital stack. It is calculated by multiplying each loan’s interest margin by its proportion of total borrowing, then summing the results. This metric provides SME property developers and industry professionals with an accurate view of overall funding costs, allowing for precise risk assessment, financial planning, and scenario stress testing. Weighted Average Loan Margin is essential for managing debt efficiency and understanding the weighted financial exposure across a development project’s financing structure.
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 Interest Rate, as both are closely related measures used to assess similar aspects of performance or risk.
