Project Level Internal Rate of Return (IRR) measures the overall profitability of a property development project by considering all invested capital, including both debt and equity. Unlike Equity IRR, which focuses solely on the developer’s equity returns, Project Level IRR accounts for the entire capital stack—loan drawdowns, interest payments, and all cash flows throughout the project. This metric provides a comprehensive view of financial performance, helping UK property developers and investors evaluate the viability and efficiency of development finance arrangements and make informed decisions within the competitive UK property market.
This sits beneath Equity-Based Returns, introducing a more specific variant of the measure without changing its core interpretation. It is commonly considered alongside Adjusted IRR for Drawdown Delays, as both are closely related measures used to assess similar aspects of performance or risk. In funding terms, Project Level IRR is most commonly encountered in connection with Split Return Above Hurdle (e.g. 70/30 to Sponsor) within the property development capital stack.
