Is Cost of Goods Sold a Debit or Credit? An Explanation (with examples)

Cost of goods sold aka. COGS, would be treated as a debit. COGS represents the direct costs associated with producing the goods sold by a company.  Put more simply- COGS is the cost of making the item that you're selling.   Therefore, cost of goods sold is considered an expense and expense accounts are always increased by debits.  

What is Cost of Goods Sold (COGS)?

Cost of goods sold refers to the direct costs incurred in producing the goods that a company sells. These costs include materials,  components, freight, duties, packaging, direct labor, and any other expenses directly related to the production process. COGS is a fixture a company's income statement and is used to calculate gross profit.

The Importance of COGS in Accounting

Accurately calculating and recording COGS is essential for several reasons:

1. Determining gross profit: By subtracting COGS from revenue, you can determine your company's gross profit, which is a key indicator of profitability.
2. Tax purposes: COGS is a tax-deductible expense, which means that accurately recording it can help reduce your company's taxable income.
3. Inventory valuation: COGS is used to determine how much your inventory asset is worth, which is a crucial asset on your balance sheet.

Example 1: Calculating COGS for a Bakery

Let's consider a real-world example to illustrate the concept of COGS. Suppose you own a bakery and want to calculate your cost of goods sold for a batch of 100 cupcakes. The  materials (flour, sugar, eggs, etc.) cost $50, and the direct labor (bakers' wages) amounts to $100. In this case, your COGS for the batch of cupcakes would be:

COGS = Direct Materials + Direct Labor COGS = $50 + $100 COGS = $150

Example 2: COGS for a Furniture Manufacturer

Now, let's consider a more complex example involving a furniture manufacturer. The company produces a line of wooden chairs, and the following costs are incurred for each chair:

• Materials (wood, screws, glue): $30
• Direct labor: $20
• Overhead costs (rent, utilities) allocated per chair: $10

To calculate the COGS for each chair, we use the following formula:

COGS = Direct Materials + Direct Labor + Allocated Overhead COGS = $30 + $20 + $10 COGS = $60

Is COGS a Debit or Credit?

In double-entry accounting, every transaction affects at least two accounts. One account is debited, while the other is credited. So, is cost of goods sold a debit or credit? The answer is that cost of goods sold is always a debit.

Understanding Debits and Credits

Before we explore why COGS is a debit, let's review the basics of debits and credits in accounting:

• Debits increase asset and expense accounts, while credits decrease them.
• Credits increase liability, revenue, and equity accounts, while debits decrease them.

Why is COGS a Debit?

Cost of goods sold is an expense , and as mentioned earlier, expense accounts are increased by debits. When you record COGS, you are essentially tracking the cost of the products that you've sold. By debiting the COGS account, you are increasing the expense on your income statement, which in turn reduces your net income.

The Journal Entry for COGS

When you record cost of goods sold, the journal entry would look like this:

In this entry, you debit the COGS account and credit the inventory account. This transaction represents the transfer of the cost of the goods from your inventory to the cost of goods sold expense.

Example:  Debiting COGS and Crediting Inventory

Let's consider a real-world example to show how this works in practice.  Robin Golf sells golf equipment.  Their best selling item is the Men's Essentials 9-Club Set, which has a COGS of $150.  Let's assume for simplicity the company only buys a single unit.   Then the unit is sold to the customer for $300.  Here's what that flow would look like:

Step 1: Purchase of the Men's Essentials 9-Club Set:

In this step, Robin Golf purchases the item for $150 (COGS). The inventory account, an asset on the balance sheet, is debited, while the accounts payable account, a liability on the balance sheet, is credited.

Step 2: Sale of the Men's Essentials 9-Club Set:

When the widget is sold, several transactions occur:

1. The accounts receivable account, an asset on the balance sheet, is debited for $300, representing the amount the customer owes the company.
2. The sales account, a revenue account on the income statement, is credited for $300, reflecting the income earned from the sale.
3. The cost of goods sold account, an expense on the income statement, is debited for $150, representing the cost of the widget that was sold.
4. The inventory account, an asset on the balance sheet, is credited for $150, reflecting the removal of the widget from the company's inventory.

The net effect of this transaction on the income statement is an increase in revenue by $300 and an increase in COGS by $150, resulting in a gross profit of $150 ($300 - $150).

Inventory Valuation Methods and COGS

The inventory valuation method a company uses can significantly impact its COGS. The three most common methods are:

1. First-In, First-Out (FIFO): Under this method, the oldest inventory items are sold first, and COGS is based on the cost of the earliest purchased goods.
2. Last-In, First-Out (LIFO): With LIFO, the newest inventory items are sold first, and COGS is based on the cost of the most recently purchased goods.
3. Weighted Average: This method calculates the average cost of all inventory items and uses that average to determine COGS.

The Impact of COGS on Profitability

As a business owner, understanding the impact of COGS on your profitability is crucial. By accurately tracking and managing your COGS, you can make informed decisions about pricing, production, and inventory management. Lowering your COGS can lead to higher gross profits and, ultimately, a healthier bottom line.

Common Problems with Inaccurate Accounting for COGS and Inventory

Inaccurate accounting of cost of goods sold or inventory assets can lead to significant problems for a company.

If COGS is understated, the company's gross profit and net income will be overstated, painting an unrealistic picture of the company's profitability. This can mislead investors, creditors, and management, leading to poor decision-making based on inaccurate financial information. On the other hand, if COGS is overstated, the company's profitability will appear lower than it actually is, which can negatively impact investor confidence and the company's ability to secure financing.

Incorrectly accounting for inventory assets can also lead to issues. Overstating inventory value can make a company appear more financially stable than it really is, while understating inventory value can result in a lower reported asset value on the balance sheet. These inaccuracies can cause problems with inventory management, tax reporting, and compliance with financial reporting standards. To avoid these issues, it is crucial for companies to maintain accurate and up-to-date records of their inventory and cost of goods sold, regularly review their accounting processes, and adhere to generally accepted accounting principles (GAAP).

Companies can also employ the use of advanced software and tools to ensure accuracy and compliance.  Inventory management systems (IMSs) such as Luminous, Cin7, and Extensiv can give company operators better visibility into their inventory asset, while companies like Unit IQ offer powerful AI tools that allow businesses to quickly and accurately manage their COGS without excel or accounting software.    

Strategies for Reducing COGS

There are several strategies you can employ to reduce your cost of goods sold:

1. Negotiate better prices with suppliers
2. Optimize your production process to reduce waste and increase efficiency
3. Implement inventory management techniques to minimize holding costs and avoid obsolescence
4. Regularly review and update your pricing strategy to ensure profitability

Conclusion

In conclusion, cost of goods sold is a critical component of accounting for any inventory-based business. As an expense account, COGS is always recorded as a debit in your financial records. By understanding the concept of COGS, how to calculate it, and its impact on profitability, you can make informed decisions to optimize your business's financial performance. Remember, accurately tracking and managing your COGS is key to ensuring the long-term success and growth of your company.
