Predetermined Overhead Rate Formula How to Calculate?

On the other hand, the machine hours were used to absorb overheads in a machine incentive environment. For instance, it has been the traditional practice retained earnings balance sheet to absorb overheads based on a single base. For instance, a business with a labor incentive environment absorbs the overhead cost with the labor hours. On the other hand, the business with the machine incentive environment absorbs overhead based on the machine hours.

How To Calculate

Hence, one of the major advantages of predetermined overhead rate formula is that it is useful in price setting. The estimated or budgeted overhead is the amount of overhead determined during the budgeting process and consists of manufacturing costs but, as you have learned, excludes direct materials and direct labor. Examples of manufacturing overhead costs include indirect materials, indirect labor, manufacturing utilities, and manufacturing equipment depreciation. Another way to view it is overhead costs are those production costs that are not categorized as direct materials or direct labor. The production manager has told us that the manufacturing overhead will be $ 500,000 for the whole year and the company expected to spend 20,000 hours on direct labor. The management concern about how to find a predetermined overhead rate for costing.

Divide budgeted overheads with the level of activity

• When monitoring and controlling overheads, businesses need some standard, to compare actual overheads with, to understand whether the budget is being properly followed.
• Its production department comes up with the details of how much the overheads will be and what other costs will be incurred.
• These calculations are performed at the beginning of the estimated period in which the analysis is to be made.
• Detailed cost analysis helps to estimate the cost of overheads with accuracy.

The overhead is then applied to the cost of the product from the manufacturing overhead account. The overhead used in the allocation is an estimate due to the timing considerations already discussed. It’s a simple step where budgeted/estimated cost is divided with the level of activity calculated in the third stage. It’s called predetermined because both of the figures used in the process are budgeted. Therefore, the result would say that the predetermined overhead rate equals the estimated cost of manufacturing divided by the units in the allocation base.

While it may become more complex to have different rates for each department, it is still considered more accurate and helpful because the level of efficiency and precision increases. This information can help you make decisions about where to cut costs or how to allocate your resources more efficiently. A good rule of thumb is to ask yourself if the cost will be incurred regardless of how much product you’re making.

For example, the office rent mentioned earlier can’t be directly linked to any one good or service produced by the business. Also, if the rates determined are nowhere close to being accurate, the decisions based on those rates will be inaccurate, too. Departmental overhead rates are needed because different processes are involved in production that take place in different departments. The allocation base (also known as the activity base or activity driver) can differ depending on the nature of the costs involved. Further, overhead estimation is useful in incorporating seasonal variation and estimate the cost at the start of the project.

Why Do We Need to Calculate Predetermined Overhead Rate?

Manufacturing overheads are predetermined overhead rate indirect costs which cannot be directly attributed to individual product units and for this reason need to be applied to the cost of a product using a predetermined overhead rate. The predetermined overhead rate, also known as the plant-wide overhead rate, is used to estimate future manufacturing costs. Traditionally, overheads have been absorbed in the product cost based on a single basis of apportionment. For instance, in a labor-intensive environment, labor hours were used to absorb overheads.

Predetermined Overhead Rate Basis

The business is labor-intensive, and the total hours for the period are estimated to be 10,000. This option is best if you’re just starting out and don’t have any historical data to work with. The best way to predict your overhead costs is to track these costs on a monthly basis. But before we dive deeper into calculating predetermined overhead, we need to understand the concept of overhead itself. Small companies typically use activity-based costing, while large organizations will have departments that compute their own rates. If the actual overhead at the end of the accounting period is 1,575 the overhead is said to be under applied by 125 (1,450 – 1,575).
