COGS is the direct cost of producing or purchasing goods sold during a period. Gross profit margin = (Revenue - COGS) / Revenue × 100%. FIFO (First-In, First-Out) assumes oldest inventory is sold first; LIFO (Last-In, First-Out) assumes newest inventory is sold first. Inventory turnover = COGS ÷ Average Inventory.

COGS determines your gross profit — Walmart's COGS is 75% of revenue while Apple's is only 57%. The FIFO vs LIFO choice during inflation can swing reported profits by millions. This calculator computes COGS using beginning inventory, purchases, and ending inventory.
Key Takeaways
- COGS = Beginning Inventory + Purchases - Ending Inventory
- Gross Profit = Revenue - COGS
- FIFO vs LIFO impacts taxes during inflation

How It Works
Start with beginning inventory, add net purchases (purchases + freight - returns - discounts), subtract ending inventory. The result is the cost of goods that left your business during the period.
For manufacturers, COGS includes raw materials, direct labor, and manufacturing overhead. Retailers use purchase cost plus freight-in.

Frequently Asked Questions
What is Cost of Goods Sold (COGS)?
COGS is the direct cost of producing or purchasing goods sold during a period. It includes materials, direct labor, and manufacturing overhead. COGS = Beginning Inventory + Purchases - Ending Inventory. It determines gross profit and is a key metric for pricing and profitability analysis.
What is gross profit margin and how is it calculated?
Gross profit margin = (Revenue - COGS) / Revenue × 100%. It shows the percentage of revenue left after direct production costs. A 40% gross margin means 40 cents of every dollar remains to cover operating expenses and profit. Walmart has ~25% gross margin; Apple has ~43%.
What is the difference between FIFO and LIFO?
FIFO (First-In, First-Out) assumes oldest inventory is sold first; LIFO (Last-In, First-Out) assumes newest inventory is sold first. During inflation, FIFO yields lower COGS and higher profits; LIFO yields higher COGS and lower taxes. LIFO is banned under IFRS but allowed under US GAAP.
What is inventory turnover and why does it matter?
Inventory turnover = COGS ÷ Average Inventory. It measures how quickly inventory is sold. Higher turnover means faster sales and less capital tied up. Low turnover may indicate overstocking or slow-moving items. Retail typically aims for 4-6x annually.
What is the difference between COGS and operating expenses?
COGS are direct costs tied to producing/purchasing goods sold (materials, labor, freight-in). Operating expenses are indirect costs of running the business (rent, marketing, salaries, utilities). COGS is subtracted from revenue to get gross profit; operating expenses are subtracted from gross profit to get operating income.
What are direct vs indirect costs in COGS?
Direct costs are traceable to specific products: raw materials, direct labor, freight-in. Indirect costs (manufacturing overhead) are allocated: factory rent, equipment depreciation, utilities. Both can be included in COGS for manufacturers. Retailers typically have simpler COGS (purchase cost + freight).
