Formula: Inventory ÷ average daily consumption  Example: Inventory: 10,000 units Daily consumption: 200 units → Days of inventory = **50 days**   ### Benchmarks - 20–60 days = typical - < 20 days = risk - >= 60 days = high capital commitment   ### Significance This metric helps manage: - replenishment - capital commitment - delivery capability ### Optimization - more accurate forecasts - adjustment of [safety stock](https://bitergo.com/en/glossary/safety-stock) - better replenishment planning   ### Relation to other KPIs - [inventory turnover](https://bitergo.com/en/glossary/inventory-turnover) - [out-of-stock](https://bitergo.com/en/glossary/out-of-stock) rate   ### Practical Example Reduction of days of inventory from 80 to 45 days: → lower storage costs with stable delivery capability   ### ❓ FAQ ### Which is better: high or low range? A medium range is ideal—balance is key.  ### How often should I calculate? Regularly (daily or weekly).  ### Conclusion  Days of inventory is a key control metric for inventory and liquidity.  ##### Bitergo GmbH Saarlandstr. 117 44139 Dortmund Germany +49 231 878008-0 [wecare@bitergo.com](mailto:wecare@bitergo.com) ##### Company - [About us](https://bitergo.com/profile) - [Information Security](https://bitergo.com/information-security-iso-27001) - [People at Bitergo](https://bitergo.com/team) - [Career](https://bitergo.com/en/career) - [Contact](https://bitergo.com/contact) ##### Products - [Bitergo WMS](https://bitergo.com/bitergo-warehouse-management-system) - [Bitergo WMS Free](https://bitergo.com/bitergo-wms-free) - [Bitergo Warehouse Automation](https://bitergo.com/warehouse-automation-with-bitergo) ##### Resources - [Blog](https://bitergo.com/en/blog) - [WMS-Calculator](https://bitergo.com/cost-savings-calculator) - [References](https://bitergo.com/references) - [Media](https://bitergo.com/media) - [WMS Academy](https://bitergo.com/wms-academy) - [Glossary](https://bitergo.com/en/glossary)   ##### Support - [Support Services](https://bitergo.com/en/support) - [AI Support-Assistant](https://bitergo.com/support-ai-assistant) ##### [Prices](https://bitergo.com/prices)   [![ISO_27001_Horizontal](https://bitergo.com/hs-fs/hubfs/ISO_27001_Horizontal.png?width=200&height=75&name=ISO_27001_Horizontal.png)](https://bitergo.com/information-security-iso-27001) ISO 27001-certified Information Management System for **Bitergo WMS** and **Bitergo Warehouse Automation**   © Bitergo GmbH [Legal information](https://bitergo.com/imprint) | [Privacy](https://bitergo.com/privacy) | Cookie-Settings [LinkedIn icon](https://www.linkedin.com/company/bitergo-gmbh) ```json { "@context" : "https://schema.org", "@type" : "BlogPosting", "author" : { "@type" : "Person", "name" : "Bitergo", "url" : "https://bitergo.com/en/glossary/author/bitergo" }, "dateModified" : "2026-04-13T13:35:01.131Z", "datePublished" : "2026-04-13T10:03:33.000Z", "headline" : "Days of Inventory – Definition, Calculation & Benchmarks", "mainEntityOfPage" : { "@id" : "https://bitergo.com/en/glossary/days-of-inventory", "@type" : "WebPage" }, "publisher" : { "@type" : "Organization", "logo" : { "@type" : "ImageObject", "url" : "https://bitergo.com/hubfs/bitergo-logo-1.svg" }, "name" : "Bitergo GmbH" } } ```
