If you’re running a business that sells products—whether it’s handcrafted jewelry, gourmet coffee, or high-end electronics—understanding your Cost of Goods Sold (COGS) is essential. COGS is more than just a figure on your income statement; it’s a core component of your business’s profitability. Knowing what it includes and how it affects your bottom line can empower you to make smarter decisions about pricing, manufacturing, and inventory control.
So, what exactly is COGS, and why does it matter?
What is Cost of Goods Sold?
Cost of Goods Sold represents the direct costs attributable to the production of the goods sold by a company. This includes the cost of materials and labor directly used to create the product. Importantly, it excludes indirect expenses such as distribution costs and sales force expenditures.
In simpler terms, COGS is what it costs you to make or buy the products you sell during a specific period. For retailers, this usually means the purchase price of inventory. For manufacturers, it’s the cost of raw materials and labor.

Items Included in COGS
The inclusion of costs in COGS depends on the nature of your business. Here’s what commonly counts:
- Raw materials: Basic inputs required to make the product.
- Direct labor: Wages paid to workers directly involved in manufacturing.
- Factory overhead: Utilities, depreciation of factory equipment, and maintenance.
- Freight-in: Cost of shipping raw materials to your facility.
- Packaging costs: If required for the product to be sellable.
Items not included in COGS:
- Administrative expenses
- Marketing and advertising
- Research and development
- Distribution costs post-manufacturing
Why COGS is Important
COGS plays a pivotal role in determining a company’s gross profit and gross margin. Here’s a quick formula:
Gross Profit = Revenue – COGS
Higher COGS reduces your gross profit, which directly affects the bottom line. By managing and reducing your COGS where possible, you can significantly improve profitability. Understanding COGS also helps with:
- Pricing strategy: Set prices that cover costs and generate a healthy margin.
- Inventory management: Discover which products are profitable and which aren’t.
- Tax calculation: Since COGS is deductible, it can reduce your taxable income.
How to Calculate COGS
Calculating COGS requires knowing your inventory levels at the beginning and end of a period. The basic formula is:
COGS = Beginning Inventory + Purchases During the Period – Ending Inventory
Here’s a simplified example:
- Beginning Inventory: $10,000
- Purchases During the Year: $15,000
- Ending Inventory: $8,000
COGS = $10,000 + $15,000 – $8,000 = $17,000

COGS and Accounting Methods
How you calculate COGS also depends on your accounting method. There are several inventory valuation methods, such as:
- FIFO (First In, First Out): Assumes older inventory is sold first.
- LIFO (Last In, First Out): Assumes most recent inventory is sold first.
- Weighted Average Cost: Averages the cost of all inventory items available.
Each method can result in different COGS figures, which can influence taxes and net income. For example, in periods of rising prices, FIFO usually results in lower COGS and higher net income, while LIFO gives higher COGS and lower taxable income.
Analyzing COGS for Business Growth
Beyond simple calculation, analyzing your COGS over time can reveal trends and inefficiencies. Ask yourself:
- Are raw material costs rising faster than sales prices?
- Is there excess waste or loss during production?
- Can automation or outsourcing reduce labor costs?
Use this analysis to streamline operations. Perhaps you can negotiate better supplier deals or switch to cheaper—but still quality—materials.
Final Thoughts
Understanding and managing your Cost of Goods Sold is crucial for healthy financial performance. While it might seem like just another accounting term, COGS touches nearly every decision you make—from pricing and budgeting to operations and taxes. Get it right, and you’ll have a firm grip on your business’s true profitability.
