COGS formula
A common inventory formula is beginning inventory + purchases − ending inventory = cost of goods sold. It estimates the inventory cost associated with goods sold during the period.
Example
If beginning inventory is 30,000, purchases are 80,000 and ending inventory is 25,000, COGS is 85,000.
Accounting method matters
Inventory valuation rules such as FIFO, weighted average and permitted tax methods can affect reported costs. Freight-in, production labor and overhead treatment also vary by business and accounting policy.
