#2 – Indirect Manufacturing Expenses or Manufacturing Overhead Expenses

This can also be called Production overhead, works overhead etc.. Overhead is the total cost of indirect – material, wages and expenses. Indirect material, wages, and expenses mean materials, wages, and expenses which cannot be linked directly with the units produced.

Example of indirect material is stores consumed for repair and maintenance work, small tools, fuel, and lubricating oil etc. Example of indirect wages is wages for maintenance work, holding pay, etc.  Example of an indirect expense is training expense, depreciation of factory shed, insurance premium for plant and machinery, factory shed etc.

By-Product

In most manufacturing operations the production of the main product is accompanied by the production of a sub-product which has a certain value on sale. This sub-product is called as a by-product because its production is not consciously undertaken but results out of the production of the main or primary product. An example is (i) molasses is by-product of sugar, (ii) buttermilk is the by-product of a dairy which produces butter and cheese etc.

It is usually difficult to ascertain the cost of the product. Moreover, its value usually forms a small portion of the main product. It is often treated as “Miscellaneous income” but the correct treatment would be to credit the sale value of the by-product to manufacturing account so as to reduce to that extent the cost incurred to manufacture the main product.
