Holding Cost in Fulfillment: What It Is and Why It Matters

When it comes to fulfillment costs, storage fees often get the most attention. But there’s a hidden cost many ecommerce and retail brands overlook: holding cost. These ongoing expenses of keeping inventory in a warehouse can quietly eat into profit margins if they’re not carefully managed.

What Is Holding Cost in Fulfillment?

Holding cost in fulfillment, also called carrying cost, is the total expense of storing unsold inventory in a warehouse. It includes storage fees, insurance, depreciation and obsolescence, shrinkage from theft or damage, and the opportunity cost of capital tied up in unsold products. In short, the longer your inventory sits, the more it costs—even if it isn’t selling.

Understanding and managing holding costs is essential for profitability, especially for eCommerce and retail brands where fast turnover is key.

What’s Included in Holding Costs?

Holding costs typically include the following:

Storage fees: Monthly or per-pallet charges for storing inventory in a fulfillment center.


Insurance: Coverage costs for protecting stored goods.


Depreciation and obsolescence: Loss in value over time, especially for perishable or seasonal products.


Shrinkage: Loss due to theft, damage, or administrative error.


Opportunity cost: The money tied up in unsold inventory that could have been used for new products or marketing.

Even if your 3PL charges a flat fee for storage, these indirect costs still affect your overall margins.

How to Reduce Holding Costs

Reducing holding costs comes down to improving inventory turnover and optimizing your warehousing strategy. Here are some proven tactics:

1. Improve Forecasting
Accurate demand forecasting helps avoid overordering and prevents slow-moving inventory from clogging up space.

2. Use Just-in-Time Replenishment
For B2B or high-volume DTC brands, just-in-time strategies reduce the need to hold excess inventory for long periods.

3. Organize Inventory by Turnover Rate
Storing high-volume SKUs in more accessible areas improves picking speed and frees up premium storage space for fast movers.

4. Optimize Packaging and Storage
Reducing product dimensions through smart packaging helps you fit more inventory into less space—lowering storage costs and shipping fees.

5. Partner with a 3PL That Tracks Inventory Accurately
Real-time inventory tracking helps you quickly spot deadstock, forecast reorder points, and reduce unnecessary storage.
