Plant Wide And Departmental Overhead Absorption Rates

departmental overhead rate formula

A second method, frequently referred to as the traditional two stage allocation approach, recognizes that there are service areas and producing areas in the plant. Usually, only one overhead rate is developed for each producing department, although the basis for these rates may differ between departments. The various producing departments might use direct labor hours, equivalent units, material costs or machine hours, as an allocation basis.

In the case of manufacturing overheads, employees would have roles such as maintenance personnel, manufacturing managers, materials management staff, and quality control staff. It would also include the set wages for janitorial staff members. Once again, the key difference lies in the nature of their respective jobs and the physical location in which their jobs are carried out. This includes the cost of hiring external law and audit firms on behalf of the company.

Predetermined Overhead Rate Formula

Let us take the example of ort GHJ Ltd which has prepared the budget for next year. The company estimates a gross profit of $100 million on total estimated revenue of $250 million. As per the budget, direct labor cost and raw material cost for the period is expected to be $40 million and $60 million respectively.

Although this rule largely differs depending on the size of the business, the business’s cash-flow, and the competitive nature of the business, it serves as a model rule for most small competitive businesses to operate on. Administrative overheads include items such as utilities, strategic planning, and various supporting functions. These costs are treated as overheads due to the fact that they aren’t directly related to any particular function of the organization nor does it directly result in generating any profits.


Although each product passes through both departments, the products do not consume the department resources in the same proportions. As indicated in Exhibit 6-14, X1 requires a larger proportion of cutting time, while X2 requires a larger proportion of assembly time. In managerial accounting, rather than using one overhead rate to allocate all of the overhead costs, overhead costs can be broken down by departments. Departmental overhead rates offer the flexibility to use a different activity or cost driver for each department. Often, some departments will rely heavily on manual labor while others require more machinery. Direct labor hours can be important to certain departments but machine hours might work better for others. A departmental overhead rate is a standard charge based on the units of activity produced by a business segment.

  • This lesson provides an explanation of the break-even point, how the break-even point is calculated and presents the break-even point formula.
  • Despite these costs occurring periodically and sometimes without prior preparation, they are usually one-off payments and are expected to be within the company’s budget for travel and entertainment.
  • Per unit labor hours can be calculated by dividing the total labor hours used to manufacture each product by the number of units manufactured.
  • You also need the total number of direct labor hours and the direct labor hours required to produce each product the plant manufactures.
  • Thus, the equations show that the total costs of a producing department includes the department’s direct cost , plus the allocations from the various service departments (i.e., the sum of []).

The following are common accounting tools which take account of business overheads. This will include company-paid business travels and arrangements. As well as refreshments, meals, and entertainment fees during company online bookkeeping gatherings. Despite these costs occurring periodically and sometimes without prior preparation, they are usually one-off payments and are expected to be within the company’s budget for travel and entertainment.

Single And Departmental Overhead Absorption Rates

Utility bills, raw materials, labor, employees, equipment and everything that factors into the production of a product will enter the predetermined overhead rate calculation. Historic overhead rates are useful for analyzing consistent expenses and expenses that spike seasonally. The prime cost is the sum of direct labor and direct material costs of a business.

Otherwise a single departmental rate will not provide accurate product costs. A third method, referred to as activity based product costing, also involves a two stage allocation process where the first stage is essentially the same as in the traditional departmental overhead rate formula two stage approach. However, in the second stage of the ABC approach, overhead costs are separated into cost pools so that different types of costs can be traced to products more accurately using different types of activity measures.

You are required to calculate the predetermined overhead rate. Calculate the cost of Job 845 using the plantwide overhead rate based on machine hours. Costs to manufacture a product include direct materials, direct labor and overhead. In this lesson, you’ll learn how overhead is allocated to finished products using absorption and marginal costing. Make a comprehensive list of indirect business expenses including items like rent, taxes, utilities, office equipment, factory maintenance etc.

Applied overhead is a fixed charge assigned to a specific production job or department within a business. The related video shows an example problem and the calculations required. It also shows how plantwide overhead rates can skew the numbers.

Organizations that use this approach tend to have simple operations within each department but different activities across departments. One department may use machinery, while another department may use labor, as is the case with SailRite’s two departments. This assumption of a causal relationship is increasingly less realistic as production processes become more complex. The overhead is attributed to a product or service on the basis of direct labor hours, machine hours, direct labor cost etc. The overhead absorption rate is calculated to include the overhead in the cost of production of goods and services. It’s used to define the amount to be debited for indirect labor, material and other indirect expenses for production to the work in progress. In managerial accounting, rather than using one overhead rate to allocate all of the overhead costs, we can break up overhead costs by department.

Estimated Total Manufacturing Overhead Costs

An overhead rate, or predetermined overhead rate, is an equation that allocates a certain amount of manufacturing overhead to each direct labor or machine hour. This rate helps businesses allocate resources and set pricing. A plant-wide overhead rate is a single rate used to assign or allocate all of a company’s manufacturing overhead costs to its production output. Thus, only the products that use the expensive equipment in a specific department will be assigned a higher overhead rate of perhaps $70 per departmental machine hour. In allocating indirect costs to products, when will a plant wide overhead rate provide accurate product costs? The objective of this approach is to create equal gross profit percentages for all joint products.

Managerial accounting is the process of identifying, measuring, analyzing, interpreting and communicating information for the pursuit of an organization’s goals. Add up the overhead from each department to calculate the total overhead applied. It creates a bias toward direct labor reduction as a cost reduction technique rather than overall productivity improvement. Overheads now constitute the Largent share of cost, often greater than 50% and is typically applied to products as percentage of the smallest cost leading to serious distortion of product cost. This costing system is assumed not to be affected much by technology changes and production methods and products are subject to slow rate of changes. Balance sheet is a financial statement which outlines a company’s financial assets, liabilities, and shareholder’s equity at a specific time. Both assets and liabilities are separated into two categories depending on their time frame; current and long-term.

Support func­tions and their costs have shown increasing trends continually. Thus, at present, overheads normal balance are less affected by production volume , but more by range and complexity of products manufactured.

Some businesses use the simple method of a single overhead rate. Therefore, choosing the method that provides the most accurate results for a particular business can help the owners and managers remain competitive within a given industry.

This would not apply if company has own internal lawyers and audit plans. Due to regulations and necessary annual audits to ensure a satisfactory work place environment, these costs often cannot be avoided. Also, since these costs do not necessarily contribute directly to sales, they are considered as indirect overheads.

2 Approaches To Allocating Overhead Costs

The dual rate or flexible budget method refers to using separate rates, or allocations for fixed and variable service costs. The purpose of this method is to prevent the actual cost allocations to users from being influenced by the quantity of service consumed by other users. Allocating fixed and variable service costs using a single actual rate can result in a variety of cost distortions.

For example, if a machining department charges $30 of overhead per machining hour, and a job uses 2.5 hours of machine time, then the overhead allocation will be $75. The various functional areas within a manufacturing facility are usually separated into two types of departments. Producing departments convert raw, or direct materials into finished products. Service departments provide support services to the other departments in the plant.

From the « fairness and equity » perspective, one could argue that these costs should not be allocated at all, or if they are allocated to the various segments of a company, the « ability to bear » logic should be used. In such cases departmental overhead absorption of respective departments is applied to the jobs or units depending on the time spent in each department instead of single overhead absorption rate. Heurion Company is a job-order costing firm that uses a plantwide overhead rate based on direct labor hours. Overapplied overhead occurs when the actual overhead cost is less than the amount of overhead cost applied to jobs during the period.

Under this method, budgeted overheads are divided by the sale price of units of production. The rent is $600 per month, cable is normal balance $150 per month, and groceries are $450 per month. You decide to take the $1,200 cost and divide it evenly by the four of you.
