Please find out more about calculating your inventory costs, why they affect your business, and what types of inventory costs exist.

What are Inventory Costs?

Inventory costs are the carrying costs of inventory or the costs associated with keeping inventory on hand. They can include storage costs, insurance, taxes, and shrinkage (the loss of inventory due to theft or damage).

The importance of inventory cost management cannot be overstated. Inventory represents a significant investment in a business, and it is important to keep track of the associated costs to make sound financial decisions. 

There are several different types of inventory costs, which will be discussed in more detail below.

The most common type of inventory cost is the storage cost. This includes the cost of renting or leasing space to store inventory, utilities (such as electricity and heating/cooling), and other maintenance expenses.

Insurance is another important type of inventory cost. This protects businesses against loss due to fire, flood, theft, or other disasters. 

The insurance premium is based on the value of the inventory being insured.

Taxes are also a significant type of inventory cost for many businesses. Inventory is typically subject to property taxes, and businesses may also incur sales tax on sold inventory.

Finally, shrinkage refers to inventory loss due to theft or damage. This can be a major problem for businesses, especially those that sell high-value items such as electronics or jewellery. 

Shrinkage can be difficult to quantify, but it nonetheless represents a real cost for businesses.

Importance of Inventory Costs to a Business

Inventory costs are the costs associated with keeping and managing inventory. They can include storage costs, obsolescence costs, and shrinkage costs.

Inventory costs are a significant expense for businesses, and they can significantly impact a company's bottom line. 

To effectively manage inventory costs, it is important for businesses to understand the different types of inventory costs and how they can be controlled.

Storage Costs

Storage costs are the expenses associated with storing inventory. They can include the cost of rent or mortgage payments for warehouse space, the cost of insurance for inventory, and the cost of labour for employees who handle inventory.

Obsolescence Costs

Obsolescence costs are the expenses associated with inventory that is no longer sellable. 

This can happen when products become outdated or damaged. Obsolescence costs can also occur when there is a change in consumer demand and businesses are left with excess inventory that they cannot sell.

Shrinkage Costs

Shrinkage costs are the expenses associated with inventory that is lost or stolen. 

This can happen due to employee theft, shoplifting, or damage during shipping or storage. Shrinkage is a major problem for businesses and can significantly impact profitability.

Inventory management is a crucial part of running a successful business. By understanding the different types of inventory costs and how to control them, businesses can save money and improve their bottom line.

Different Types of Inventory Costs

Different types of inventory costs can have a significant impact on a company's bottom line. 

It is important to understand the different types of inventory costs and how they can be managed to keep them under control.

The four main types of inventory costs are:

  1. Storage Costs: These are the costs associated with storing inventory, such as rent for warehouse space, utilities, insurance, and security. They can be minimized by efficient storage practices and careful selection of storage locations.
  2. Ordering Costs: These are the costs associated with placing orders for new inventory, such as the cost of materials, labour, shipping, and administrative expenses. They can be minimized by streamlining the ordering process and negotiating better terms with suppliers.
  3. Stock-Out Costs: These are the costs associated with not having enough inventory on hand to meet customer demand, such as lost sales, the opportunity cost of lost sales, or lost production time due to downtime. They can be minimized by effective forecasting and planning to ensure that adequate stock levels are maintained at all times.
  4. Obsolescence Costs: These are the costs associated with inventory that becomes outdated or no longer needed, such as storage costs, disposal costs, or write-off of unsold items. They can be minimized by careful selection of products and regular review of inventory levels to ensure that obsolete

How to Calculate Inventory Cost

A company incurs inventory costs to hold or store inventory. The purpose of the inventory is to provide a buffer between production and sales so that a company can continue to produce even when sales are slow.

There are several methods of calculating inventory cost, but the first-in, first-out (FIFO) method is the most common. 

Under this method, the costs of the oldest units in inventory are charged to expense first.

To calculate inventory cost using the FIFO method, start by adding up the costs of all the purchased units during the period being accounted for. This will give you the total cost of goods available for sale.

Next, subtract the sales from this number to get the ending inventory balance. Finally, divide this number by the number of units in ending inventory to get the average cost per unit. 

This average cost per unit can then be applied to future sales to determine the cost of goods sold.

Inventory Cost Considerations

Inventory cost considerations are important to take into account when making business decisions regarding inventory. 

There are several types of inventory costs, including opportunity costs, storage costs, and carrying costs.

Opportunity cost is the value of the best alternative use of resources. For example, suppose a company has $100,000 to invest and uses it to buy inventory instead of investing in new equipment. 

In that case, the opportunity cost is the return that could have been earned from investing in new equipment.

Storage costs are incurred when inventory is stored. These can include renting space to store inventory, paying for insurance on stored inventory, and paying employees to manage and monitor stored inventory.

Carrying costs are incurred when inventory is carried or held by a company. These can include the cost of financing the purchase of inventory, the cost of storage space for holding inventory, and the opportunity cost of not using the funds invested in inventory for other purposes.
