Beginning inventory + purchases - ending inventory
Value of inventory at start of period
Cost of inventory purchased or raw materials
Value of inventory at end of period
Total sales revenue for the period
COGS = Beginning Inventory + Purchases - Ending Inventory
Gross Profit = Revenue - COGS
For manufacturing businesses, add direct labor and manufacturing overhead to purchases before subtracting ending inventory.
Included
Raw materials, direct labor, manufacturing overhead, freight-in, factory supplies
Not Included
Marketing, sales commissions, administrative salaries, office rent, distribution costs
Cost of Goods Sold (COGS) represents the direct costs attributable to the production of goods that a company sells. This includes the cost of materials, direct labor, and manufacturing overhead directly used to create the product. COGS is a critical metric for understanding a company's profitability and pricing strategy.
COGS is deducted from revenue to determine gross profit. A lower COGS relative to revenue means a higher gross margin, indicating the company is efficient in producing its goods. Monitoring COGS helps businesses identify cost reduction opportunities and maintain competitive pricing.
Income Statement Impact
COGS is the first expense deducted from revenue on the income statement, resulting in gross profit. It directly affects operating income, net income, and all profitability ratios. Accurate COGS calculation is essential for reliable financial reporting.
Tax Implications
COGS is a tax-deductible expense. Higher COGS means lower taxable income. Businesses must use consistent and accepted inventory valuation methods (FIFO, LIFO, or weighted average) as required by tax regulations.
Balance Sheet Connection
COGS connects the income statement to the balance sheet through inventory. As goods are sold, their cost moves from the inventory asset on the balance sheet to COGS on the income statement.
Negotiate with Suppliers
Secure volume discounts, explore alternative suppliers, and negotiate better payment terms. Building strong supplier relationships can lead to preferential pricing and priority service.
Improve Production Efficiency
Implement lean manufacturing, reduce waste, automate repetitive tasks, and optimize workflows. Even small efficiency gains compound over time into significant cost savings.
Optimize Inventory Management
Use just-in-time (JIT) inventory, implement demand forecasting, and minimize carrying costs. Reducing excess inventory frees up cash and reduces storage and obsolescence costs.
