Selecting an Estimated Activity Base
The movie industry uses job order costing, and studios need to allocate overhead to each movie. Their amount of allocated overhead is not publicly known because while publications share how much money a movie has produced in ticket sales, it is rare that the actual expenses are released to the public. The predetermined overhead rate calculation shown in the example above is known as the single predetermined overhead rate or plant-wide overhead rate.
Allocation Bases
This can result in abnormal losses as well and unexpected expenses being incurred.
Concerns Surrounding Predetermined Overhead Rates
Knowing the total and component costs of the product is necessary for price setting and for measuring the efficiency and effectiveness of the organization. Remember that product costs consist of direct materials, direct labor, and manufacturing overhead. A company’s manufacturing overhead costs are all costs other than direct material, direct labor, or selling and administrative costs. Once a company has determined the overhead, it must establish how to allocate the cost.
- Keep reading the article to learn more about the predetermined overhead rate and how to calculate and apply it.
- Overhead for a particular division, product, or process is commonly linked to a specific allocation base.
- Larger organizations tend to employ a different POHR in each department which improves the accuracy of overhead application even though it increases the amount of required accounting labor.
- Also, if the rates determined are nowhere close to being accurate, the decisions based on those rates will be inaccurate, too.

The limitations and problems of the predetermined overhead rate are that they are not always realistic, accurate decision-making can be affected, and historical costs do not always match current costs. The rate avoids collecting actual manufacturing overhead costs as part of the closing period. As you have learned, the overhead needs to be allocated to the manufactured product in a systematic and rational manner. This allocation process depends on the convention of conservatism use of a cost driver, which drives the production activity’s cost. Examples can include labor hours incurred, labor costs paid, amounts of materials used in production, units produced, or any other activity that has a cause-and-effect relationship with incurred costs. The overhead cost per unit from Figure 6.4 is combined with the direct material and direct labor costs as shown in Figure 6.3 to compute the total cost per unit as shown in Figure 6.5.
As explained previously, the overhead is allocated to the individual jobs at the predetermined overhead rate of $2.50 per direct labor dollar when the jobs are complete. When Job MAC001 is completed, overhead is $165, computed as $2.50 times the $66 of direct labor, with the total job cost of $931, which includes $700 for direct materials, $66 for direct labor, and $165 for manufacturing overhead. For example, the total direct labor hours estimated for the solo product is 350,000 direct labor hours. With $2.00 of overhead per direct hour, the Solo product is estimated to have $700,000 of overhead applied. When the $700,000 of overhead applied is divided by the estimated production of 140,000 units of the Solo product, the estimated overhead per product for the Solo product is $5.00 per unit.
Another way to view it is overhead costs are those production costs that are not categorized as direct materials or direct labor. A predetermined overhead rate is calculated at the start of the accounting period by dividing the estimated manufacturing overhead by the estimated activity base. The predetermined overhead rate is then applied to production to facilitate determining a standard https://www.kelleysbookkeeping.com/understanding-your-small-businesss-current-assets/ cost for a product. A predetermined overhead rate is an allocation rate that is used to apply the estimated cost of manufacturing overhead to cost objects for a specific reporting period. This rate is frequently used to assist in closing the books more quickly, since it avoids the compilation of actual manufacturing overhead costs as part of the period-end closing process.
The computation of the overhead cost per unit for all of the products is shown in Figure 6.4. Managers and accounting personnel should work together to analyze the historical overhead information to look for relationships between the total overhead and one of the specific allocation bases. A manager may notice https://www.kelleysbookkeeping.com/ that the overhead rate is usually about one and a half times the cost of direct labor for a given project. If this is consistent for many projects in that department over the past year, then predetermined overhead for that department would be computed by multiplying the estimated cost for direct labor by 150%.
