Introduction
Cost of Goods Sold (COGS) is an essential financial metric that determines the direct costs attributable to the production of products sold by a company. This expense reflects the cost of materials and labor directly involved in creating goods. Understanding how to calculate COGS is crucial, as it can help businesses accurately determine their profits, inventory valuations and tax liabilities.
Calculating Cost of Goods Sold
Calculating COGS requires several pieces of financial data. Here is a step-by-step guide on how to calculate cost of goods sold:
1. Determine Beginning Inventory: This is the value of inventory at the start of an accounting period. You can find this information on your previous accounting period’s balance sheet.
2. Calculate Purchases: Throughout the accounting period, keep track of all additional inventory you acquire due to purchases made for raw materials, work-in-progress items, and finished goods. Do not forget to incorporate import duties and transportation costs — these are considered part of your overall inventory cost.
3. Calculate Labor & Overhead Costs: These are manufacturing costs and expenses incurred during the process of transforming raw materials into finished products. Labor costs include wages, salaries, and benefits paid to employees who contribute directly to the production process, while overhead costs include rent for production facilities, utilities, and depreciation on manufacturing equipment.
4. Add Total Available Inventory: Sum up beginning inventory, purchases, and labor & overhead costs to determine total available inventory for the accounting period:
Total Available Inventory = Beginning Inventory + Purchases + Labor & Overhead Costs
5. Determine Ending Inventory: At the end of your accounting period, conduct a physical count or use specialized software to determine the value of unsold finished goods in your possession.
6. Calculate Cost of Goods Sold: Finally, subtract ending inventory from total available inventory to arrive at your COGS:
Cost of Goods Sold = Total Available Inventory – Ending Inventory
Example of Cost of Goods Sold Calculation
Let’s say a clothing manufacturer has the following financial data:
– Beginning Inventory: $30,000
– Purchases: $100,000
– Labor & Overhead Costs: $60,000
– Ending Inventory: $40,000
Here’s how they would calculate their COGS:
Total Available Inventory = Beginning Inventory ($30,000) + Purchases ($100,000) + Labor &Overhead Costs ($60,000) = $190,000
Cost of Goods Sold = Total Available Inventory ($190,000) – Ending Inventory ($40,000) = $150,000
Conclusion
Understanding and accurately calculating Cost of Goods Sold is key to maintaining a healthy bottom line and ensuring prudent inventory management. Careful consideration of each element involved in determining COGS is essential for businesses looking to optimize profits and control costs.
