Opening stock Work done in current period Direct materials Conversion costs €23,000 €10,000 €25,000 €11,000 The following table summarises the costs assigned to units completed and those still in progress under the weighted-average and FIFO process-costing methods for our example. Weighted Average (Solution Exhibit Cb bFIFO (Solution Exhibit 4.21) Difference Cost of units completed and transferred out Work in progress, closing Total costs accounted for €3,192,866 322,134 €3,515,000 €3,188,000 327,000 €3,515,000 −€4,866 +€4,866 The FIFO closing stock is higher than the weighted-average closing stock by €4,866. This is because FIFO assumes that all the lower-cost prior-period units in work in progress are the first to be completed and transferred out while closing work in progress consists of only the higher- cost current-period units. However, the weighted-average method smoothes out cost per equivalent unit by assuming that more of the higher-cost units are completed and transferred out while some of the lower-cost units in opening work in progress are placed in closing work in progress. Hence, in this case, the weighted-average method results in a higher cost of units completed and transferred out and a lower closing work-in-progress stock relative to FIFO.
