In a cost sheet, Work-in-Progress (WIP) adjustments are made to determine the accurate Factory Cost. Opening WIP is added as it signifies work from the previous period finalized in the current one. Closing WIP is subtracted as it represents work commenced but not finished within the current period.
Cost Sheet Treatment:
Prime Cost: ₹ 20,00,000
Add: Factory Overheads: ₹ 8,00,000
Gross Works Cost: ₹ 28,00,000
Add: Opening WIP: ₹ 2,00,000
Sub-Total: ₹ 30,00,000
Less: Closing WIP: ₹ 1,40,000
Factory Cost: ₹ 28,60,000
Consequently, the Factory Cost, adjusted for WIP, amounts to ₹ 28,60,000.
This calculation ensures the cost sheet reflects solely the expenses incurred for work completed within the reporting period.
