Enter the total starting value of an inventory, the net purchases, and the cost of goods sold to calculate the ending inventory and turnover.

Ending Inventory Formula

The following formula can be used to calculate the ending inventory value.

Ending Inventory = (BI+ NP) - (CG)
  • Where BI is the initial inventory amount ($)
  • NP is the net purchases ($)
  • CG is the cost of goods sold ($)

To calculate the ending inventory, sum the beginning inventory and net purchases, then subtract the cost of goods sold.

The inventory turnover can than further be calculated using the ending inventory, beginning inventory, and cost of goods sold.
