## Definition of 'Average Cost Method'

The average cost method is a method of valuing inventory that is based on the average cost of all units purchased during a period. It is a weighted-average method, meaning that the cost of each unit is calculated by multiplying its quantity by the average cost of all units purchased during the period.

The average cost method is often used by businesses that sell a large number of similar items, such as grocery stores or department stores. It is also used by businesses that produce their own products, such as manufacturers or bakeries.

To calculate the average cost per unit, you add up the cost of all units purchased during the period and divide by the total number of units purchased. For example, if you purchase 100 units of inventory at \$10 each and 200 units at \$12 each, the average cost per unit would be \$11.

The average cost method is easy to use and understand, and it provides a consistent way to value inventory. However, it can sometimes produce inaccurate results if the prices of inventory items fluctuate significantly during the period.

Another disadvantage of the average cost method is that it does not take into account the specific costs of individual units of inventory. This can be a problem if some units of inventory are more expensive than others.

For these reasons, the average cost method is not always the best method for valuing inventory. In some cases, it may be more appropriate to use a different method, such as the first-in, first-out (FIFO) method or the last-in, first-out (LIFO) method.
