  • 22. 22 Indirect expenses  Such as rent, rates, depreciation, maintenance expenses that do not have instant relationships with the manufacturing processes
  • 23. 23 Cost accumulation •Prime cost = direct materials + direct labour + direct expenses •Production cost = Prime cost + factory overhead OR = Direct materials + Conversion cost *Conversion cost is the production cost of converting raw materials into finished product •Total cost = Prime cost + Overheads (admin, selling,distribution cost) OR = Production cost + period cost (administrative, selling, distribution and finance cost) •Period cost is treated as expenses and matched against sales for calculating profit, e.g. office rental
