What is weighted average cost inventory?

In accounting, the Weighted Average Cost (WAC) method of inventory valuation uses a weighted average to determine the amount that goes into COGS. The weighted average cost method divides the cost of goods available for sale by the number of units available for sale.

How do I calculate a weighted average?
