How the calculation works
COGS = beginning inventory + net purchases and direct costs − ending inventory
Use the result as a planning aid. Check the source records and the assumptions before making financial decisions.
Follow inventory through the period
The tool uses beginning inventory plus purchases minus ending inventory to calculate cost of goods sold. Use consistent inventory valuation and period boundaries.
Keep the model in scope
This simplified inventory model does not replace the accounting policies for manufacturing costs, freight, returns or valuation adjustments. For turnover, use average inventory rather than only the ending balance.
