Process Costing
Normal loss- Expected loss forms part of cost of product,
arises from opening WIP or newly started production.
Abnormal loss- Unexpected can be avoided(Accident),
-not part of normal process of manufacturing.
-Recorded as a expense, not allocated to product cost.
-Only arises from newly started production
Abnormal Gain-need knowledge won’t need to apply in question,
Expected loss> Actual loss.
Steps in process costing
  1. Timeline
  2. Inputs/outputs table( FIFO Split completed into opening WIP and
     newly started, Split normal loss into the 2 categories,) Only have
     abnormal loss from closing WIP) (Weighted average, completed from
     whole process, normal, abnormal all from whole process)
  3. Allocation of normal loss(Split. Between completed, closing WIP,
     Abnormal loss)Table (Slides) only relates to newly started
     production.
  4. Equivalent units(FIFO, Current period) (Weighted Average, Current
     and prevois period)
  5. Calculate total costs(FIFO, Current period costs) (Weighted average,
     Current and previous period costs)
  6. Cost per equivalent units
  7. Allocate costs
  8. Answer the required
     If abnormal loss occurs at a different stage in the process it does not
      attract part of the normal lost.
