Forge Ltd provides the following data for the year ended 31 December 2023. Calculate the production cost of finished goods.
- Opening inventory of raw materials: $15,000
- Purchases of raw materials: $85,000
- Closing inventory of raw materials: $12,000
- Direct factory wages: $60,000

Show solution outline
Step 1: Calculate Cost of Raw Materials Consumed Opening Inventory + Purchases - Closing Inventory $15,000 + $85,000 - $12,000 = $88,000
Step 2: Calculate Prime Cost
Step 3: Add Factory Overheads
Step 4: Calculate Production Cost before WIP adjustment
Step 5: Adjust for Work in Progress (WIP) Cost before WIP + Opening WIP - Closing WIP $182,000 + $8,000 - $11,000 = $179,000
Final Answer: The production cost of finished goods is $179,000.
