Days Sales of Inventory: What Is, How to Calculate + Formula

Understanding DSI is crucial for optimizing warehouse operations and enhancing financial performance.

The inventory turnover ratio is a related metric to DSI that measures the number of times a company sells and replaces its inventory within a given period.

That is nearly $27,000 of cash released back into operations without any increase in sales or reduction in costs. For example, holiday sales might result in a temporary drop, while post-season inventory can push DSI higher. Misinterpreting these trends could lead to unnecessary changes in your strategy.
