Absorption Rate (Units/month) is a key metric in property development finance UK that calculates the average number of units sold or let per month within a development. It indicates the speed at which a project’s inventory moves through the market, providing critical insight into sales and letting efficiency. Developers and lenders use absorption rate to forecast cash flow, evaluate market demand, and plan project exit strategies, influencing loan drawdowns and interest costs. The rate can vary by property type, location, and market conditions, making it an essential measure for both SME developers and professional investors managing development finance risk.
This sits beneath Sales/Lettings Velocity, introducing a more specific variant of the measure without changing its core interpretation. It is commonly considered alongside Void Period Mean (days), as both are closely related measures used to assess similar aspects of performance or risk.
