  • These are indirect costs, and it is difficult to control them, unlike direct costs, as they don`t have a direct link with the output and, in some cases, are difficult to allocate as well.
  • The allocation of factory overhead is a cumbersome process, and there is no single method that is entirely objective. Due to this limitation, at times, such overhead leads to the wrong estimation of production cost or rendering a service.
  • Another big drawback is that allocation is generally based on machine hours or labor hours. However, it has been observed that not all factory overhead is linked to these factors; expenses like rent, insurance taxes are not affected by these factors much.


  • Factory Overhead is a significant expense incurred by the business, especially in manufacturing set up, and it involves all indirect expenses which cannot be directly attributable to any particular job or work is undertaken.
  • However, their importance is equal, just like direct expenses, and needs to be accounted for with utmost care. Another critical factor is the general nature of these expenses. Most of these are fixed or semi-variable, unlike direct costs, which are mostly variable. As such, business needs to understand these factory overheads holistically and keep a tab on them as these are most difficult to control and also at the same time pivotal to the success of a business.
