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. Sales of each product have been strong, and the total gross profit for each product is shown in Figure 6.7. Using the Solo product as an example, 150,000 units are sold at a price of $20 per unit resulting in sales of $3,000,000. The cost of goods sold consists of direct materials of $3.50 per unit, direct labor of $10 per unit, and manufacturing overhead of $5.00 per unit.

How to calculate the predetermined overhead rate: Example 3

There are several concerns with using a predetermined overhead rate, which include are noted below. Small companies typically use activity-based costing, while large organizations will have departments that compute their own rates. Different businesses have different ways of costing; some use the single rate, others use multiple rates, and the rest use activity-based costing. After reviewing the product cost and consulting with the marketing department, the sales prices were set.

Nonetheless, ignoring overhead costs, like utilities, rent, and administrative expenses that indirectly contribute to the production process of these gadgets, would result in underestimating the cost of each gadget. The predetermined overhead rate formula can be used to balance expenses with production costs and sales. For businesses in manufacturing, establishing and monitoring an overhead rate can help keep expenses proportional to production volumes and sales. It can help manufacturers know when to review their spending more closely, in order to protect their business’s profit margins. If the job in work in process has recorded actual material costs of 4,640 for the accounting period then the predetermined overhead applied to the job is calculated as follows.

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. This allocation can come in the form of the traditional overhead allocation method or activity-based costing.. 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 cost for a product.

The predetermined overhead rate formula is calculated by dividing the total estimated overhead costs for the period by the estimated activity base. 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. The computation of the overhead cost per unit for all of the products is shown in Figure 6.4.

In order to estimate the predetermined overhead rate it is first necessary to to decide on an activity base on which to apply overhead costs to a product. This is related to an activity rate which is a similar calculation used in Activity-based costing. A pre-determined overhead rate is normally the term when xero reviews using a single, plant-wide base to calculate and apply overhead. Overhead is then applied by multiplying the pre-determined overhead rate by the actual driver units. Any difference between applied overhead and the amount of overhead actually incurred is called over- or under-applied overhead. The predetermined overhead rate is used to price new products and to calculate variances in overhead costs.

Materials Cost Example

A business can calculate its actual costs periodically and then compare that to the predetermined overhead rate in order to monitor expenses throughout the year or see how on-target their original estimate was. This comparison can be used to monitor or predict expenses for the next project (or fiscal year). Using the predetermined overhead rate formula and calculation provides businesses with a percentage they can monitor on a quarterly, monthly, or even weekly basis. Businesses monitor relative expenses by having an idea of the amount of base and expense that is being proportionate to each other. This can help to keep costs in check and to know when to cut back on spending in order to stay on budget.

Overhead costs are then allocated to production according to the use of that activity, such as the number of machine setups needed. In contrast, the traditional allocation method commonly uses cost drivers, such as direct labor or machine hours, as the single activity. 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. However, the difference between the actual and estimated amounts of overhead must be reconciled at least at the end of each fiscal year.

In addition while manufacturing overheads might vary seasonally throughout the year, the use of a constant predetermined rate avoids a similar variation in unit product cost. Prior to the start of the accounting year, JKL Corp calculates the predetermined annual overhead rate to be used in the new year. JKL’s profit plan for the new year includes $1,200,000 as the budgeted amount of manufacturing overhead. JKL allocates the manufacturing overhead based on the normal and expected number of production machine hours which are 20,000 for the new year.

1. But determining the exact overhead costs is not easy, as the cost of electricity needed to dry, crush, and roast the nuts changes depending on the moisture content of the nuts upon arrival.
2. 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.
3. The estimated manufacturing overhead cost applied to the job during the accounting period will be 1,494.
4. Depending on the size of the business the predetermined overhead rate might be calculated for the whole business or, for a larger business, separate rates might be calculated for each department using a suitable basis.

The use of previous accounting records to derive the amount of manufacturing overhead may not always be the best, because prices increase all the time, and customer expectations and industry trends are constantly changing. As a result, there is a high probability that the actual overheads incurred could turn out to be way different than the estimate. At the end of the accounting period the applied overhead is compared to the actual overhead and any difference is posted to the cost of goods sold or, if significant, to work in process. The use of historical information to derive the amount of manufacturing overhead may not apply if there is a sudden spike or decline in these costs. This is a particular concern in highly competitive industries where production rates may vary dramatically, based on the popularity of the latest round of product releases. Hence, you can apply this predetermined overhead rate of 66.47 to the pricing of the new product X.

These overhead costs involve the manufacturing of a product such as facility utilities, facility maintenance, equipment, supplies, and labor costs. Whereas, the activity base used for the predetermined overhead rate calculation is usually machine hours, direct labor hours, or direct labor costs. Added to these issues is the nature of establishing an overhead rate, which is often completed months before being applied to specific jobs. Establishing the overhead allocation rate first requires management to identify which expenses they consider manufacturing overhead and then to estimate the manufacturing overhead for the next year. Manufacturing overhead costs include all manufacturing costs except for direct materials and direct labor.

The estimate is made at the beginning of an accounting period, before the commencement of any projects or specific jobs for which the rate is needed. Therefore, this predetermined overhead rate of 250 is used in the pricing of the new product. The activity base for applying manufacturing overhead is normally a unit quantity which relates to the manufacturing process such as the following. Companies need to make certain the sales price is higher than the prime costs and the overhead costs. In some industries, the company has no control over the costs it must pay, like tire disposal fees. To ensure that the company is profitable, an additional cost is added and the price is modified contra asset account as necessary.

The application rate that will be used in a coming period, such as the next year, is often estimated months before the actual overhead costs are experienced. Often, the actual overhead costs experienced in the coming period are higher or lower than those budgeted when the estimated overhead rate or rates were determined. At this point, do not be concerned about the accuracy of the future financial statements that will be created using these estimated overhead allocation rates. You will learn in Determine and Disposed of Underapplied or Overapplied Overhead how to adjust for the difference between the allocated amount and the actual amount. Therefore, in simple terms, the POHR formula can be said to be a metric for an estimated rate of the cost of manufacturing a product over a specific period of time. That is, a predetermined overhead rate includes the ratio of the estimated overhead costs for the year to the estimated level of activity for the year.

For example, the costs of heating and cooling a factory in Illinois will be highest in the winter and summer months and lowest in the spring and fall. If the overhead rate is recomputed at the end of each month or each quarter based on actual costs and activity, the overhead rate would go up in the winter and summer and down in the spring and fall. As a result, two identical jobs, one completed in the winter and one completed in the spring, would be assigned different manufacturing overhead costs. To avoid such fluctuations, actual overhead rates could be computed on an annual or less-frequent basis. However, if the overhead rate is computed annually based on the actual costs and activity for the year, the manufacturing overhead assigned to any particular job would not be known until the end of the year. For example, the cost of Job 2B47 at Yost Precision Machining would not be known until the end of the year, even though the job will be completed and shipped to the customer in March.

If the predetermined overhead rate calculated is nowhere close to being accurate, the decisions based on this rate will definitely be inaccurate, too. That is, if the predetermined overhead rate turns out to be inaccurate and the sales and production decisions are made based on this rate, then the decisions will be faulty. When there is a big difference between the actual and estimated overheads, unexpected expenses will definitely be incurred. Also, profits will be affected when sales and production decisions are based on an inaccurate overhead rate. If a job is in work in process and has recorded actual direct labor hours of 600 during an accounting period then the predetermined overhead applied to the job is calculated as follows.
