COGS represents the direct costs of producing or purchasing the products you sell. It includes only the cost of inventory sold during a specific time period—not overhead, rent, or payroll.
Formula
COGS = Beginning Inventory + Purchases During the Period − Ending Inventory
Example:
Let’s say you started the year with $15,000 in inventory. You purchased $50,000 in new stock throughout the year. At the end of the year, your remaining inventory is $10,000.
COGS = $15,000 + $50,000 − $10,000 = $55,000
That means your cost of goods sold for the year is $55,000.
Why it matters
COGS directly affects your gross profit and helps you understand how much it costs to keep products on the shelf. Accurate COGS helps with pricing, inventory planning, and tax reporting.
