Internal Rate of Return (IRR) is a key metric in property development finance UK that measures the annualised percentage return earned on invested capital over the project life. It represents the discount rate that equates the net present value (NPV) of all project cash inflows and outflows to zero. IRR captures timing and scale of cash flows, allowing developers and investors to assess project profitability and compare multiple development opportunities on an equivalent basis. Typically expressed as a percentage, it aids decision-making on equity deployment in UK property development projects.

It is commonly considered alongside Equity IRR, as both are closely related measures used to assess similar aspects of performance or risk. In funding terms, Internal Rate of Return (IRR) is most commonly encountered in connection with Preferred Return Based on IRR Hurdle within the property development capital stack.
