CA Intermediate · Cost and Management Accounting · Joint Products and By Products

In a chemical plant, a single process yields products P and Q jointly. Which of the following costs is, by definition, a 'joint cost' in this context?

Joint cost is the cost of materials, labour and overheads incurred up to the split-off point, where the joint products become separately identifiable. Costs of further processing, packing or selling after separation are specific to each product and are therefore not treated as joint costs.

  1. ACost of further processing Q after the split-off point
  2. BCost of packing P in retail cartons after separation
  3. CSelling expenses incurred on Q
  4. DCost of materials and conversion incurred up to the split-off pointCorrect

Explanation

Joint costs are the costs of raw material, labour and overheads incurred up to the split-off point, before the products become separately identifiable. Costs of further processing, packing and selling after separation are separable (post-split-off) costs specific to a product, so they are not joint costs.
