In UK property development finance, the debt to total cost ratio—commonly referred to as the loan-to-cost (LTC) ratio—measures the proportion of a development project’s overall cost that is financed through debt. This total cost includes land acquisition, construction expenses, professional fees, and contingency allowances. Calculated by dividing the total borrowing amount by the full development cost, the LTC ratio indicates the level of external funding and lender exposure. Maintaining an appropriate LTC ratio is essential for achieving a balanced capital structure, effectively managing financial risk, and supporting the successful delivery of development projects on schedule and budget.
This sits beneath Leverage Ratios, introducing a more specific variant of the measure without changing its core interpretation. It is commonly considered alongside Debt to CFADS at Stabilisation, as both are closely related measures used to assess similar aspects of performance or risk. In funding terms, Debt to Total Cost is most commonly encountered in connection with 1st Charge + Top-Up in Same Loan within the property development capital stack.
