The research found that guidelines of setting manufacturing cost of small ceramic factory were calculated by using normal costing. Due to the factory manufactured various products by using the same basic materials. Therefore, in allocating costs to products, so use an estimate of the expenses to the product which is to be used, the cost of raw materials and labor. The expense in the production section use estimate using the Plant wide Rate. the estimated expenses were divided into three parts; cost of direct materials, direct labor and manufacturing overhead. The rate of manufacturing overhead based on product volume. For example,
