A major advantage of using the FIFO process-costing method is that:
◦ FIFO makes the unit cost calculations simpler
◦ in contrast with the weighted-average method, FIFO is considered GAAP
◦ FIFO provides managers with information about changes in the costs per unit from one period to the next
◦ in the period of rising prices, it leads to lower operating income and lower tax payments, saving the company cash and increasing the company's value
