Storage costs

If you don’t know your storage costs, you can’t control them. Here you can find out what types of costs are involved in warehousing, how to calculate storage costs, and what levers you can pull to reduce your warehousing costs in a targeted manner.

What are storage costs and why are they so important?

Storage costs are all expenses incurred by storing goods, raw materials, or finished products in a warehouse and include fixed storage costs such as rent and depreciation as well as variable storage costs such as personnel, energy, and capital commitment, which together determine the economic cost of warehousing.

In everyday language, storage costs and warehousing costs are often used synonymously. Both terms refer to the totality of all costs associated with maintaining inventory. In most companies, storage costs are the largest single item within logistics costs:

• In industry, warehousing accounts for around 50 percent of logistics costs.
• In wholesale and retail, the share is even higher, at 60 to 80 percent.
• The average warehousing cost rate across all industries ranges between 15 and 35 percent of the inventory value.

This is precisely why transparent recording and regular calculation of warehousing costs is so crucial. Only those who know where the costs arise can optimize in a targeted manner and strengthen their own competitiveness.

Fixed and variable storage costs at a glance

When calculating storage costs, it is essential to distinguish between fixed and variable storage costs. Fixed storage costs are incurred regardless of inventory levels, while variable storage costs rise or fall with the quantity of goods stored.

Fixed storage costs

Fixed storage costs include, among other things:

• Rent or lease for storage space
• Depreciation on shelving systems and conveyor technology
• Basic insurance for buildings and equipment
• Basic fees for IT systems and warehouse management software

These costs remain constant, regardless of whether the warehouse is 30 or 90 percent full. In Germany, the average peak rent for modern logistics warehouses is currently around EUR 7.60 per square meter per month.

Variable storage costs

Variable storage costs change with the size of the warehouse and the activity in the warehouse:

• Personnel costs for order picking and warehouse management
• Energy costs for lighting, heating, and cooling
• Consumables such as packaging and labels
• Maintenance and repair of equipment and conveyor systems

Personnel costs are the largest single item among storage costs, accounting for 40 to 55 percent.

Capital commitment costs and risk costs

An often underestimated component of storage costs is capital commitment costs. Every euro tied up in inventory is not available for investment or other business purposes. It is common to calculate a 5 percent interest rate on the average inventory value. Added to this are risk costs due to shrinkage, spoilage, damage, or obsolescence of the goods.

Cost Type	Type	Examples	Typical Share
Personnel costs	variable	Order pickers, warehouse management	40 to 55 %
Facility costs	fixed	Rent, cleaning, property tax	20 to 26 %
Depreciation	fixed	Shelving, forklifts, conveyor systems	6 to 14 %
Capital holding costs	variable	Interest on tied-up capital	5 to 12 %
Insurance	fixed	Goods insurance, building insurance	2 to 9 %
Other costs	variable	Energy, IT, packaging	3 to 8 %

Calculating storage costs using a formula and example

Storage costs are calculated in two steps. First, all cost types are added together, then the storage cost rate is determined as a percentage.

Calculating storage costs in euros

The total storage costs are calculated by adding up all individual items:

Total storage costs = space costs + personnel costs + capital commitment costs + depreciation + insurance + other costs

Calculating the storage cost rate

The storage cost rate compares the total storage costs to the average storage value:

Storage cost rate (%) = Total storage costs ÷ Average inventory value × 100

Determining average storage costs and average inventory value

You can calculate the average inventory value as follows:

Average inventory value = (Opening balance in EUR + Closing balance in EUR) ÷ 2

Calculation example: A trading company has the following annual storage costs:

Item	Amount
Personnel costs (3 warehouse employees)	18,000 EUR
Facility costs (rent, energy, cleaning)	10,500 EUR
Depreciation (shelving, forklifts)	6,200 EUR
Capital holding costs (5% on avg. inventory value)	5,000 EUR
Insurance	2,400 EUR
Other costs (IT, packaging)	1,900 EUR
Total warehouse costs	44,000 EUR

The inventory value at the beginning of the year is EUR 180,000 and at the end of the year EUR 220,000. The average inventory value is therefore EUR 200,000.

Inventory cost rate = 44,000 ÷ 200,000 × 100 = 22 percent

This means that the inventory cost rate shows potential for optimization, as the benchmark is 15 percent or less.

Warehouse Cost Rate	Assessment
Below 15%	Well optimized
15 to 25%	Industry standard, optimization potential available
Above 25%	Significant need for action

Factors influencing storage costs

Several variables determine how high your storage costs actually are:

• Storage location: There are considerable differences between Munich, at around EUR 10.50 per square meter, and secondary locations, at EUR 4.00 to 5.50 per square meter. A central location, such as in the Rhine-Main area, offers short transport routes at more moderate space prices.
• Inventory level: The higher the inventory, the more capital is tied up. A high turnover rate significantly reduces the average storage costs per item.
• Degree of automation: Automated warehouses have higher depreciation costs but lower personnel costs per unit moved. The ratio of fixed to variable storage costs shifts.
• Seasonal fluctuations: Storage space is fully utilized during peak periods and partially empty during quiet periods. Fixed storage costs continue to run in both cases.
• Assortment complexity: A broad assortment with many SKUs requires more storage space, more complex picking, and higher administrative costs than a lean product portfolio.

Reducing storage costs with the right levers

Inventory optimization and key performance indicator management

The most effective lever for reducing storage costs is to reduce average inventory levels without compromising delivery capability. The following measures have proven effective in practice:

• Performing an ABC analysis to identify items with the largest share of inventory value
• Regularly monitor inventory key figures such as inventory cost rate, turnover rate, and average storage duration
• Reduce excess inventory by reordering according to demand
• Introduce FIFO or FEFO principles to prevent spoilage and obsolescence

Fulfillment outsourcing as an alternative to in-house warehousing

For many companies, outsourcing warehousing to a fulfillment service provider is an economical alternative to in-house warehousing. Instead of fixed storage costs for rent, personnel, and infrastructure, you pay variable costs per pallet per month.

With an external service provider such as Lufapak, you benefit from economies of scale that a single company cannot achieve on its own. Over 20,000 square meters of warehouse and logistics space in Neuwied, ISO 9001-certified processes, and flexible scaling as needed turn fixed storage costs into predictable, variable costs.

Frequently asked questions about storage costs

What is included in storage costs?

Storage costs include space costs such as rent and energy, personnel costs for warehouse staff, depreciation on warehouse equipment and conveyor technology, capital commitment costs on tied-up inventory, insurance, and risk costs due to shrinkage, spoilage, or obsolescence.

How can storage costs be calculated?

Storage costs are calculated by adding up all storage-related cost types. You can calculate the storage cost rate by dividing the total storage costs by the average storage value and multiplying by 100. The result shows the storage costs as a percentage of the value of the goods.

What is the difference between fixed and variable storage costs?

Fixed storage costs such as rent, depreciation, and insurance are incurred regardless of the amount of stock. Variable storage costs such as personnel, energy, and packaging materials increase or decrease with the amount of goods stored and moved.

How can storage costs be reduced in e-commerce?

Effective measures include inventory optimization through key performance indicator management, reduction of excess inventory, use of shared warehousing, or outsourcing to a fulfillment service provider. Variable billing per pallet or order converts fixed storage costs into predictable, volume-dependent costs.

What is the difference between storage costs and logistics costs?

Storage costs are a sub-area of logistics costs. While storage costs only include the expenses for storing goods, logistics costs also include transport, packaging, picking, IT systems, and administrative expenses for the entire supply chain.
