Ans.
Direct manufacturing expenses are costs, other than
material or wages, which are incurred for a specific product or saleable
service.
Examples of direct manufacturing expenses are (i)
Royalties for using license or technology if based on units produced, (ii) Hire
charge of the plant and machinery used on hire, if based on units produced,
etc.When royalty or hire charges are based on units produced, these expenses
directly vary with production.
Indirect Manufacturing expenses are also called
Manufacturing overhead, Production overhead, Works overhead, etc. Overhead is
defined as total cost of indirect material, indirect wages and indirect expenses.
Overhead = Indirect Material + Indirect Wages + Indirect
Expenses
Indirect material means materials which cannot be linked
directly with the units produced, for example, stores consumed for repair and
maintenance work, small tools, fuel and lubricating oil, etc.
Indirect wages are those which cannot be directly linked
to the units produced, for example, wages for maintenance works, holding pay,
etc.
Indirect expenses are those which cannot be directly
linked to the units produced, for example, training expenses, depreciation of
plant and machinery, depreciation of factory shed, insurance premium for plant and
machinery, factory shed, etc. Accordingly, indirect manufacturing expenses
comprise indirect material, indirect wages and indirect expenses of the
manufacturing division.
