What Are Inventory Days On Hand?
Inventory days on hand, otherwise known as days of inventory on hand, is the measurement of how fast a business can turn inventory. Companies can calculate their inventory days on hand to minimize stock-outs while optimizing their inventory management.

Why Inventory Days On Hand Is Important
There are many reasons why calculating your inventory days on hand is beneficial for establishing an optimized inventory management system. Whether you’re a small or large eCommerce business, predicting accurate inventory count helps predict customer demand, which is especially vital during peak season or major holidays.
We’ll go over the other reasons why inventory forecasting is essential for your business and the best practices in this section.
1. Helps plan for the future
Calculating your inventory turnover ratio helps businesses forecast demand during peak sales periods like Black Friday through the Christmas season. In addition, understanding the average number of days helps you have a better idea of your company’s inventory 365 days a year.
2. Helps optimize your inventory management
Calculating your inventory days on hand helps eCommerce companies and merchants make informed decisions about inventory purchases. Purchasing too much inventory can be a significant drain on your resources. It can financially impact your business if the product is no longer in demand, which is where the DOH formula comes in handy.
3. Prevents fewer stockouts
The inventory days on hand formula prevents fewer stockouts and allows eCommerce merchants like yourself to have the correct inventory in stock. Fewer stockouts translate to a better customer experience.
4. Lowers costs & improves cash flows
You can significantly reduce the amount of money you spend on warehousing by maintaining a low average of inventory days on hand. So instead of paying an arm and a leg on warehousing, you can invest the freed-up cash in other areas of your eCommerce business.
5. Reduces risk of spoilage
Depending on the type of eCommerce business you run, calculating your DOH formula helps prevent any spoilage if you hold food or perishable goods in stock. The longer the items stay in inventory, the increased risk of spoilage or deadstock. This factor also applies to seasonal items (i.e., Christmas goods).
