There are some key differences between the two process costing methods, for example, the weighted-average method calculates Equivalent Units of Production by taking all units completed and transferred out and adding the equivalent units in ending work in process, whereas FIFO calculates it by taking the EU needed to complete work in process plus the number of units started, completed, and transferred out plus equivalent units in ending work in process. As you mentioned in your post, FIFO has many advantages to being used, however, what are some of the key differences in using FIFO in comparison to the weighted-average method? In what situation do you think that using an alternative to FIFO would be more appropriate when using a process costing?
