Cost of Goods Sold (COGS)

When a soap maker sells a ₹100 bar, how much of that simply went into making the bar before any marketing, salaries or profit? That number, the direct cost of production, is the Cost of Goods Sold (COGS), and it tells you a great deal about a business's quality.

What's inside COGS

COGS captures the costs tied directly to producing goods sold during a period: raw materials, direct labour and manufacturing overheads. It deliberately excludes indirect costs like advertising, head-office salaries and distribution, which sit lower in the statement.

The master formula every analyst uses is simple:

Gross Profit = Revenue − COGS, and Gross Margin % = Gross Profit ÷ Revenue.

Gross margin is the cleanest measure of how much a company earns from its core product before overheads, and tracking it over time reveals pricing power and cost discipline.

Reading it in Indian financials

Here's a quirk that trips up new investors. Indian companies report under Schedule III of the Companies Act, 2013, which does not show a single neat "COGS" line. Instead you reconstruct it by combining three items: cost of materials consumed, purchases of stock-in-trade, and changes in inventories of finished goods and work-in-progress.

Add those together and you have the effective COGS. For a manufacturer, the cost of materials consumed line usually does most of the heavy lifting.

Why it matters for stock picking

Gross margin behaviour separates strong businesses from fragile ones. A premium FMCG or branded-goods company commands pricing power and tends to hold or expand its gross margin even when input costs rise. A commodity-style or low-differentiation manufacturer sees margins squeezed the moment raw-material prices climb.

Watching the trend matters more than the absolute number: a steadily widening gross margin signals pricing strength, while a shrinking one, even on rising sales, hints that the company is absorbing cost inflation it cannot pass on.

Takeaway: when you scan an Indian company's P&L, don't hunt for a "COGS" line, build it from cost of materials consumed, stock-in-trade purchases and inventory changes. Then track gross margin across several years. Consistency and direction there often reveal the true competitive strength of a business well before the bottom line does.
