Key ideas in Cost Accounting in Practice
- Product costs attach directly to goods and stay on the balance sheet as inventory until sold
- Period costs are non-manufacturing expenses like sales and admin that hit the income statement right away
- Any cost incurred inside the factory walls is a product cost, while costs outside the factory are period costs
- Making a physical product always requires three inputs: direct materials, direct labor, and manufacturing overhead
- Direct materials are traceable parts that become the physical product
- Direct labor is hands-on work directly assembling the unit
- Manufacturing overhead includes indirect factory costs like factory rent, machine depreciation, and factory utilities
- Work-in-Process gathers all direct costs and overhead as debits while products are being assembled
- Completed items are credited out of Work-in-Process as Cost of Goods Manufactured
- Cost of Goods Manufactured represents the total cost invested into goods that were finished during the period
- Finished Goods acts as a temporary holding asset on the balance sheet for unsold completed items
- Manufacturing a product does not trigger an expense; selling it does
- Purchased inputs sit first in Raw Materials inventory
- Materials flow into Work-in-Process as assembly takes place
- Finished items move into Finished Goods inventory
- The dollar finally exits the balance sheet to become Cost of Goods Sold expense when the item is sold
