In our first example formula, we used 365 days, but you can adjust this figure to align with your examination period. For instance, you could calculate the DSI ratio for a 30, 60, or 90-day period. Learn how Inventory management ensures the right stock balance to meet demand and maximize efficiency. Set Max to cover one full order cycle plus lead time (or simply “how much you’re comfortable holding”). The order quantity is usually Max − on-hand (minus on-order if you track it).

Definition of DSI

Fast-moving consumer goods generally target lower DSI (under 30 days), while luxury goods or seasonal items accept higher values. The optimal ratio balances carrying costs against stockout risks while maintaining safety stock appropriate for your lead time. Rather than seeking an arbitrary benchmark, compare your DSI to direct competitors and your historical performance to identify improvement opportunities. Unexpected surges or drops in demand can affect inventory levels and turnover times, requiring companies to adjust their inventory management strategies swiftly. Well-optimised procurement, production, and distribution processes can reduce the time inventory is held, leading to a lower DSI. Conversely, supply chain disruptions, such as raw material delays or bottlenecks, can increase DSI.

What Is Inventory Days & Why Does It Matter?

Days Sales of Inventory (DSI): Definition, Formula & Calculation

This means that it’s especially important to have good inventory management processes in place to keep up with demand. Your customers will expect prompt service without stockouts, no matter how busy the business is.

Proactively renegotiating lead times or building vendor-managed inventory agreements with critical suppliers helps shift this burden outside the plant, reducing both DSI and working capital pressure. High-turnover, high-critical parts demand https://www.bookstime.com/ tighter cycle counts and closer forecasting, while slower-moving consumables can follow more cost-efficient bulk purchasing cycles. Rather, it focuses on maintaining a healthy balance between having the right parts on hand and avoiding excessive buildup.
