Components of Inventory Cost and Ownership

TL;DR

Inventory costs include all expenses needed to get goods ready for sale, not just the purchase price. Ownership typically transfers when control and significant risks/rewards pass to the buyer. Understanding these components and ownership rules is crucial for accurate financial reporting.

1. The Mental Model

Think of inventory as a product's full "journey cost" from the supplier's door to your warehouse shelf, ready for a customer. Ownership is about who has the risks and rewards of that product at any given point.

2. The Core Material

When you're accounting for inventory, it's not just about the price you pay the supplier. All costs necessary to bring the inventory to its present location and condition are included. This is called the "cost principle".

What Goes Into Inventory Cost?

1. Purchase Price: The amount you pay the vendor for the goods.
2. Freight-In (Shipping Costs): If you, the buyer, are responsible for shipping costs to get the inventory to your location, these costs are added to the inventory's cost.
3. Taxes (Non-Refundable): Any non-refundable sales or import duties directly related to the acquisition of the inventory.
4. Insurance During Transit: If you insure the goods while they're being shipped to you, this cost is capitalized.
5. Handling Costs: Costs incurred to get the inventory ready, like receiving, unpacking, and inspecting the goods.
6. Storage Costs (Before Ready for Sale): If storage is necessary before the goods are ready for their intended use or sale (e.g., aging wine), these can be included. However, routine storage after goods are ready for sale is generally expensed as a period cost.
7. Costs of Preparing Inventory for Sale: Any costs to get the inventory into saleable condition, such as modifications or assembly.

What Doesn't Go Into Inventory Cost?

1. Freight-Out (Shipping to Customers): Costs to ship goods from you to your customers are selling expenses, not part of inventory cost.
2. Selling Costs: Advertising, sales commissions, etc.
3. General & Administrative Expenses: Office salaries, rent, utilities (unless directly tied to production).
4. Abnormal Spoilage/Waste: Costs from inefficiencies or errors are expensed, not capitalized into inventory.
5. Interest Costs: Generally expensed, unless for self-constructed assets qualifying for capitalization.

Ownership of Inventory

Determining who owns the inventory is vital for two main reasons:
1. Who reports the inventory on their balance sheet?
2. When does a sale legally occur (and revenue can be recognized)?

The key here is understanding FOB (Free On Board) shipping terms:

graph TD
    A["FOB Shipping Point"] --> B{Who Pays Freight?};
    B --> C["Buyer Pays Freight"];
    C --> D["Ownership Transfers: At Shipping Point"];
    D --> E["Buyer owns goods in transit"];

    A --> F{Who Pays Freight?};
    F --> G["Seller Pays Freight"];
    G --> H["FOB Destination"];
    H --> I{Who Pays Freight?};
    I --> J["Seller Pays Freight"];
    J --> K["Ownership Transfers: At Destination"];
    K --> L["Seller owns goods in transit"];

• FOB Shipping Point (or FOB Origin):

  • Ownership transfers to the buyer as soon as the goods are shipped by the seller (when they leave the seller's dock).
  • The buyer is responsible for freight costs (freight-in), which are added to the inventory cost.
  • The buyer bears the risk of loss or damage during transit.
  • The buyer should include these goods in their inventory, even if they haven't physically arrived yet.

• FOB Destination:

  • Ownership transfers to the buyer when the goods arrive at the buyer's destination (when they reach the buyer's dock).
  • The seller is responsible for freight costs (freight-out for the seller, an expense for them).
  • The seller bears the risk of loss or damage during transit.
  • The seller should include these goods in their inventory until they reach the buyer.

Other Ownership Scenarios:

• Consigned Goods: If you (the consignor) send goods to another party (the consignee) to sell on your behalf, you still own the goods. The consignee only holds them and earns a commission. You include these goods in your inventory.
• Goods Sold with Right of Return: If customers can return goods, you only recognize revenue and remove inventory from your books when the returns are reasonably estimable, or the return period expires. If returns aren't estimable, you might delay recognizing the sale.

3. Worked Example

Let's say "Bake-It-Easy Co." (you) buys 1,000 bags of flour from "GrainCorp".

• Invoice Price: \$5.00 per bag
• Shipping Terms: FOB Shipping Point
• Freight Cost (paid by Bake-It-Easy Co.): \$200
• Insurance during transit (paid by Bake-It-Easy Co.): \$50
• Import Duties: \$0.10 per bag
• Unpacking/Inspection Labor: \$30 (allocated to this shipment)
• Sales Commissions for selling the flour: \$0.25 per bag (paid later)
• Normal storage costs after flour is ready for sale: \$0.05 per bag per month

Calculate the total cost of inventory for this shipment:

1. Purchase Price: 1,000 bags * \$5.00/bag = \$5,000
2. Freight-In: \$200 (capitalized, as you pay it and terms are FOB Shipping Point)
3. Insurance during transit: \$50 (capitalized)
4. Import Duties: 1,000 bags * \$0.10/bag = \$100 (capitalized)
5. Unpacking/Inspection Labor: \$30 (capitalized)

Total Inventory Cost = \$5,000 + \$200 + \$50 + \$100 + \$30 = \$5,380

The cost per bag for accounting purposes is \$5,380 / 1,000 bags = **\$5.38 per bag.**

What about the other costs?
* The Sales Commissions (\$0.25 per bag) are a selling expense, expensed in the period the flour is sold.
* The Normal storage costs after flour is ready for sale (\$0.05 per bag per month) are a period cost, expensed as they occur.

Ownership: Since the terms are FOB Shipping Point, Bake-It-Easy Co. owns the flour as soon as GrainCorp ships it. If the flour was damaged in transit, it would be Bake-It-Easy Co.'s loss (though they could claim insurance if purchased).

4. Key Takeaways

• Inventory cost includes all expenses to bring goods to a saleable condition and location.
• Freight-in is added to inventory cost; freight-out is a selling expense.
• Non-refundable taxes and duties are part of inventory cost; sales commissions are not.
• FOB Shipping Point means the buyer owns goods in transit and pays freight-in.
• FOB Destination means the seller owns goods in transit and pays freight (which is freight-out for them).
• Consigned goods remain on the consignor's (owner's) balance sheet.
• Accurate inventory costing impacts Cost of Goods Sold and ultimately net income.

Common Mistakes to Avoid:
- Forgetting to include freight-in or duties in inventory cost for FOB shipping point.
- Including freight-out or sales commissions in inventory cost.
- Incorrectly accounting for goods in transit based on FOB terms.
- Confusing which party is the buyer and which is the seller when determining ownership.
- Capitalizing routine storage costs after goods are ready for sale.

You've just purchased 500 units of a new product. The invoice price was \$20 per unit. Shipping terms were FOB Destination, and the seller paid \$300 for freight. You also paid \
