Cost of Goods Sold (COGS): Meaning, Examples, Formula & Importance

🧾 Definition:

Cost of Goods Sold (COGS) refers to the direct costs incurred by a business to produce or purchase the goods it sells during a specific period.

📘 Understanding Cost of Goods Sold (COGS) in Simple Terms:

The Cost of Goods Sold includes all the direct expenses related to the production or acquisition of products. These may include raw materials, direct labor, packaging, and other production costs. It does not include indirect expenses such as office rent, salaries of admin staff, or marketing costs.

COGS is subtracted from total revenue to determine gross profit. Lower COGS = higher profit margin (assuming revenue remains the same), and vice versa.

🧠 Breakdown of COGS:

1. Components Included in COGS:

• Cost of raw materials
• Direct labor cost
• Manufacturing supplies
• Packaging costs
• Freight-in or transportation to bring goods to factory
• Purchase cost for goods sold (for traders)

2. Excluded from COGS:

• Administrative salaries
• Advertising expenses
• Distribution expenses
• Interest or depreciation

🏭 Example of COGS:

Scenario:
ABC Traders buys 500 shirts at ₹300 each to sell in retail.

• Beginning Inventory: ₹0

• Purchases: ₹1,50,000 (500 shirts × ₹300)

• Ending Inventory: ₹30,000 (100 shirts unsold)

➤ COGS = ₹1,50,000 – ₹30,000 = ₹1,20,000

That ₹1,20,000 is the cost incurred to generate revenue from 400 shirts sold.

COGS in Indian Accounting & Taxation:

In India, COGS is referred to while calculating Gross Profit and Net Profit for Income Tax purposes. For businesses under audit, accurate valuation of inventory is essential as it directly impacts taxable income.

• For manufacturers, COGS aligns with “Cost of Production” under Indian GAAP.

• Under Section 145A of the Income Tax Act, inventories must be valued including duties, taxes, freight, etc.

📈 Why COGS Is Important:

• Determines gross profit margin

• Helps track business efficiency

• Impacts pricing decisions

• Critical for tax planning and audit

• Essential for financial reporting and ratio analysis

🔢 COGS Formula:

$$\text{COGS} = \text{Opening Inventory} + \text{Purchases During the Period} – \text{Closing Inventory}$$

COGS=Opening Inventory+Purchases During the Period–Closing Inventory

📓 Journal Entry (with example):

ABC Retailer sold goods costing ₹1,00,000.

Journal Entry:

Cost of Goods Sold A/c     Dr. ₹1,00,000  
     To Inventory A/c                     ₹1,00,000  
(Being cost of goods sold during the period)

📊 Detailed Accounting Illustration:

Details:

• Opening Stock: ₹40,000

• Purchases: ₹2,00,000

• Closing Stock: ₹50,000

$$\text{COGS} = ₹40,000 + ₹2,00,000 – ₹50,000 = ₹1,90,000$$

COGS=₹40,000+₹2,00,000–₹50,000=₹1,90,000

Gross Revenue: ₹3,00,000
Gross Profit: ₹3,00,000 – ₹1,90,000 = ₹1,10,000

This calculation is presented in the Trading Account:

Particulars	Amount (₹)	Particulars	Amount (₹)
To Opening Stock	40,000	By Sales	3,00,000
To Purchases	2,00,000	By Closing Stock	50,000
To Gross Profit (Bal. fig)	1,10,000
Total	3,50,000	Total	3,50,000
