Mixed costs are costs that contain both a variable cost component and a fixed cost component.
The difference between a project overhead and general overhead may vary from project to project based on what is
billable to the project‘s owner under the construction contract with the owner. For example, one contract may
specifically allow the construction company to bill the cost of the project manager to the project, whereas another may
specifically prohibit it and require that the project manager be paid out of the profit and overhead markup.
The Tax Cuts and Job Act, passed in December 2017, eliminated the deduction for entertainment, which includes
entertainment activities, memberships to social clubs, and associated entertainment facilities. Because of this,
entertainment costs need to be tracked separately.
The best sources of data for future general overhead costs are historical costs; however, these costs must be adjusted
to take into account the uniqueness of each year’s financial objectives.
Unallocated materials include inventory shrinkage due to theft or damage.
To control general overhead costs, a budget should be prepared for the general overhead, and the general overhead
costs should be tracked.
Charitable contributions must be tracked separately because there may be limits to their tax deductibility.
First, the budget should have enough detail to allow management to track and manage costs. Second, the budget
should not have so much detail that management spends a lot of extra time and effort tracking costs or gives up
trying to track costs because it is too difficult. Third, the budget needs to provide the information necessary to prepare
financial statements and income tax returns.
To accurately project and control costs, the general overhead budget must be estimated line by line.
Because both profit and general overhead come out of the gross profit, the smaller the overhead costs, the greater the
profit.
