In UK property development finance, the time-weighted cost of finance calculates the average borrowing expense by weighting interest and fees according to both the timing and amount of funds drawn during the entire development project. This approach takes into account fluctuations in loan balances and the drawdown schedule, providing property developers with a more accurate and detailed measure of financing costs throughout each construction phase. For SME developers, understanding this metric is essential to forecast capital expenditure effectively and to manage their financing strategies in line with project cash flows and funding requirements.


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