Easy: Calculate Average Cost Inventory + Examples

The average cost method assigns a weighted average cost to each item in inventory. This approach involves dividing the total cost of goods available for sale (beginning inventory plus purchases) by the total number of units available for sale during a specific period. The resulting average cost is then used to determine the cost of goods sold and the value of ending inventory. For example, if a company starts with 100 units costing $10 each and then purchases another 50 units costing $12 each, the average cost is calculated as follows: [(100 $10) + (50 $12)] / (100 + 50) = $11.33 per unit.

Employing an average cost approach provides a simplified and smoothed valuation compared to other methods, which may fluctuate due to variations in purchase prices. This simplification is especially valuable in situations where inventory items are indistinguishable or when tracking individual item costs proves impractical. The method’s use extends to mitigating the impact of price fluctuations, promoting stability in reported financial results, and reducing the potential for income manipulation.
