Calculating Job order costing and process costing in a manufacturing company

Differences between Job order and process costing:

Similarities
  • objectives (accumulating production costs, assigning costs to products)
  • flow of costs
  • use of factory overhead accounts (normal costing system)

Differences
  • manufacturing environment
  • cost object used for cost accumulation (departments not jobs as in job order costing)
  • usually have multiple WIP accounts (includes transferred in costs included in product costs)

Manufacturing overhead applied 90,000

During the year, products costing $310,000 were completed, and products costing $316,000 were sold for $455,000.
