The controller of the Gertrude Radio Company wants to develop a predetermined overhead rate, which she can use to apply overhead more quickly in each reporting period, thereby allowing for a faster closing process. A later analysis reveals that the actual amount that should have been assigned to inventory is $48,000, so the $2,000 difference is charged to the cost of goods sold. A predetermined overhead rate, also known as a plant-wide overhead rate, is a calculation used to determine how much of the total manufacturing overhead cost will be attributed to each unit of product manufactured. The rate is determined by dividing the fixed overhead cost by the estimated number of direct labor hours.
How To Calculate
Typically, accountants estimate predetermined overhead at the beginning of each reporting period. The predetermined overhead rate is found by taking the total estimated overhead costs and dividing by the estimated allocation base. That probably makes little sense so let us look at a summary of steps and then apply it to an example. The predetermined overhead rate can be either overapplied or underapplied, depending on how accurate the company estimated the manufacturing overhead. The manufacturing overhead could be spread across all three accounts to be more accurate, but this is more time consuming.
Determining Estimated Overhead Cost
The allocation base (also known as the activity base or activity driver) can differ depending on the nature of the costs involved. Also, if the rates determined are nowhere close to being accurate, the decisions based on those rates will be inaccurate, too. Different businesses have different ways of costing; some use the single rate, others use multiple rates, and the rest use activity-based costing. This example helps to illustrate the predetermined overhead rate calculation. Departmental overhead rates are needed because different processes are involved in production that take place in different departments.
- The allocation base includes direct labor costs, direct labor dollars, or the number of machine-hours.
- This material has been prepared for informational purposes only, and should not be relied upon for tax, legal, or investment purposes.
- The predetermined overhead rate formula is calculated by dividing the estimated manufacturing overhead cost by the allocation base.
- 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.

You can envision the potential problems in creating an overhead allocation rate within these circumstances. The predetermined overhead rate is set at the beginning of the year and is calculated as the estimated (budgeted) overhead costs for the year divided by the estimated (budgeted) level of activity for the year. This activity base is often direct labor hours, direct labor this is the new tax filing deadline for 2020 returns costs, or machine hours. Once a company determines the overhead rate, it determines the overhead rate per unit and adds the overhead per unit cost to the direct material and direct labor costs for the product to find the total cost. As you’ve learned, understanding the cost needed to manufacture a product is critical to making many management decisions (Figure 6.2).
Examples of overhead costs include rent, utilities, office supplies, and administrative salaries. Now that all parts of the equation are determined let’s calculate the predetermined overhead rate. Figure 4.18 shows the monthly manufacturing actual overhead recorded by Dinosaur Vinyl.
If sales and production decisions are being made based in part on the predetermined overhead rate, and the rate is inaccurate, then so too will be the decisions. Company B wants a predetermined rate for a new product that it will be launching soon. Its production department comes up with the details of how much the overheads will be and what other costs will be incurred.
Manufacturing decisions may be influenced by what the predetermined overhead rate, rather than the true production, needs. If the predetermined overhead rate is overapplied or underapplied, the potential product demand may be miscalculated as well. Until now, you have learned to apply overhead to production based on a predetermined overhead rate typically using an activity base. An activity base https://www.kelleysbookkeeping.com/nostro-account-definition/ is considered to be a primary driver of overhead costs, and traditionally, direct labor hours or machine hours were used for it. For example, a production facility that is fairly labor intensive would likely determine that the more labor hours worked, the higher the overhead will be. As a result, management would likely view labor hours as the activity base when applying overhead costs.
To calculate the predetermined overhead, the company would determine what the allocation base is. The allocation base could be direct labor costs, direct labor dollars, or the number of machine-hours. The company would then estimate what the predetermined overhead cost would be and divide them to determine what the manufacturing overhead cost would be. The application rate that will be used in a coming period, such https://www.kelleysbookkeeping.com/ 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.
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. With 150,000 units, the direct material cost is $525,000; the direct labor cost is $1,500,000; and the manufacturing overhead applied is $750,000 for a total Cost of Goods Sold of $2,775,000. Overhead for a particular division, product, or process is commonly linked to a specific allocation base. Allocation bases are known amounts that are measured when completing a process, such as labor hours, materials used, machine hours, or energy use. The more consistency there is between the total overhead and the allocation base, the more accurate the estimate of predetermined overhead will be. Let’s assume a company has $32,000 as manufacturing overhead costs and 7,000 as machine hours.
This allocation can come in the form of the traditional overhead allocation method or activity-based costing.. To calculate the predetermined overhead rate using direct labor costs, the estimated manufacturing overhead costs would be divided by the allocation base which would be, in this case, the direct labor costs. The result of this calculation will be the predetermined overhead rate based upon the direct labor costs. 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.
It is also possible (and often recommended) for a company to use different methods depending on the specific products, processes, and services within the organization. As the predetermined overhead rate is an estimate of what the company believes will be the cost for manufacturing the product, the actual costs could be different than what they estimated. When the predetermined overhead rate is not exactly what the company estimated, the rate would be either overapplied or underapplied. This is determined by applying the actual costs of manufacturing, once known, against the estimated manufacturing costs, and the difference will determine if the predetermined overhead rate was overapplied or underapplied. Ahead of discussing how to calculate predetermined overhead rate, let’s define it. A predetermined overhead rate(POHR) is the rate used to determine how much of the total manufacturing overhead cost will be attributed to each unit of product manufactured.
After reviewing the product cost and consulting with the marketing department, the sales prices were set. The sales price, cost of each product, and resulting gross profit are shown in Figure 6.6. Small companies typically use activity-based costing, while large organizations will have departments that compute their own rates. The production hasn’t taken place and is completely based on forecasts or previous accounting records, and the actual overheads incurred could turn out to be way different than the estimate.
This can be avoided to some extent by regularly adjusting the predetermined overhead rate to align with actual costs. Larger organizations may employ a different predetermined overhead rate in each production department, which tends to improve the accuracy of overhead application by employing a higher level of precision. However, the use of multiple predetermined overhead rates also increases the amount of required accounting labor. For example, the recipe for shea butter has easily identifiable quantities of shea nuts and other ingredients.
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.
