This document discusses process costing and provides examples of how it is applied. It begins by explaining the key differences between job-order costing and process costing. Process costing accumulates costs by department rather than individual jobs. It then provides an example of calculating equivalent units of production using the weighted-average method for a department that started 6,000 units and completed 5,400 units during the period. The document also includes examples of production reports and cost flows for a process costing system.
