In this competitive market, companies must be careful regarding unnecessary expenses. Inventory holding costs are necessary for companies that store raw materials & other manufactured goods after purchasing. For any business, it is essential to maintain the balance between the holding inventories. If you have excessive inventories over time, the cost of holding inventory can be expended. The inventory carrying cost is the fee a business has to pay when they store inventory in the warehouse.

In this article, we will briefly share the cost of holding inventory. Let's look at how to calculate the inventory carrying cost & tips to minimize the cost and its benefits.

What Are Inventory Holding Costs?

Inventory holding costs refer to the expenses related to storing unsold inventory over a period of time. These costs include:

Warehouse rent and utilities
Insurance
Security
Equipment depreciation
Inventory financing
Risk of obsolescence, damage or spoilage

Holding costs can vary significantly across industries and business sizes. On average, holding costs range from 20-30% of the inventory value per year. For fast-moving consumer goods, costs tend to be on the lower end, while slow-moving spare parts can lead to very high carrying costs.

Where Inventory Holding Costs Apply

Businesses deal with inventory holding costs in facilities including:

Warehouses - Large storage facilities owned or leased by the company.
Fulfillment centers - External warehouses that handle order processing and shipping on behalf of ecommerce merchants.
Distribution centers - Facilities that store inventory and enable transportation to retail locations.
Storage units - External self-storage spaces used temporarily when warehouse capacity is exceeded.

Calculating Your Inventory Carrying Cost

You can estimate inventory carrying costs using the following formula:

Annual Holding Cost = Average Inventory Value x Carrying Cost Percentage

The carrying cost percentage represents the cost of holding inventory, expressed as a percentage of the average inventory value per year. A reasonable estimate is 25%.

Here are some proven methods to lower inventory carrying costs:

Implement inventory optimization models to align stock levels with demand.
