Overhead absorption rate is a rate charged to cost unit intended to account for the overhead at a predetermined level of activity. On the basis of direct labour hours, direct labour cost or machine hours, overhead is attributed to a product or service. If the number of units is a basis for determining overhead rate, the following formula is used. The first step in calculating overhead absorption rate is to identify all the indirect costs or overhead costs incurred by your business, or so-called company overheads. These costs may include rent, utilities, salaries and wages of support staff, depreciation, insurance, and other expenses that are not directly related to the production of goods or services. When a cost centre produces dissimilar units e.g., jobs to customer order, the volume of production must be expressed in a common measurement e.g., direct labour hours, machine hours etc.
- This method assumes that both the materials you use and the labour (i.e the wages) it takes to produce the product jointly lead to factory overheads.

- Generally machine operator’s wages area part of direct wages.
- There is a direct relationship between time factor and direct wages.
If the company has different products that take require different labour hours, the overhead absorption for each product will significantly differ for each product based on which basis it uses. Companies can also use a percentage of their costs as a basis when calculating their overhead absorption rates. These include direct material costs, direct wages or labour costs and prime costs.

Underabsorbed overhead is also known as underapplied overhead, while overabsorbed overhead is also known as overapplied overhead.

(iv) This method is not rational when part of the materials passes through all processes and part through only some processes.
(1) When material forms major part of total cost, time factor is ignored. An example of overhead absorption in the context of a manufacturing company. For each unit of product A, overhead of 8.75 is included in the total cost of the product, and for each unit of product B, overhead of 21.25 is included in the total cost. This method of overhead absorption is not commendable since its use leads to some absurd anomalies.
All products, jobs, or services pass through one or more producing cost centers. Failing to choose the most equitable and suitable method can result in misleading costing results. This simple, direct method only applies to single output industries manufacturing one product or a few grades of the same product. Not only does the company now have more affordable month-to-month expenses, but more predictable expenses that make it easier for the financial team to budget and forecast. Different companies can have different overheads depending on the nature of their industry and work. To estimate the overhead to be included in the cost of job order.
This overhead cost per unit is a blended standard of historical fixed, variable, and semi-variable costs and is especially useful for budgeting and forecasting. a freelancer’s guide to invoicing and getting paid Under this method, a machine hour rate is prepared for a group of machines. This method is followed if identical machines are used in a factory.
Sales Price Method:
(2) The total hours worked by each machine or group of machines. (1) This method cannot be used when machines are extensively used for production. (1) This method is suitable when production is carried on manually.
This method is highly suitable if the following conditions are satisfied. There is no difference between the time spent by the skilled labour and unskilled labour. This method can be easily adopted if proper records of time booking are maintained. The price fluctuation of material will not be accompanied by similar fluctuations in overhead.
( Direct Material Cost Method (Percentage on Direct Material Cost)
Under this method, the rate is calculated by expressing the overhead cost as a percentage of direct materials for the same period. Overhead absorption helps assign indirect costs to products or services in cost accounting. It has advantages, for example, being simple to use, helping with accurate product costing and pricing decisions, and improving financial reporting. However, it’s critical to consider the specific context of the business and use it alongside other methods for accurate cost allocation. The importance of overhead absorption in cost accounting lies in its ability to allocate indirect costs to products or services, facilitating accurate cost determination and decision-making. Overhead absorption helps companies include indirect costs in inventory, leading to more comprehensive financial reporting.
Direct Labour Hour Rate Method:
If so, the amount of overhead absorbed may differ from the amount of overhead actually incurred. For ease and simplicity, a common absorption rate for overheads may be used across a factory for all jobs and units of production, irrespective of the department in which they were produced. By their nature, variable costs may go down as business activity declines, but that’s not a desired outcome. Increasing profitability by trimming variable overhead costs tends to require changes in methods or increases in efficiency. Another option may be to consider a hybrid employee model in which employees work from home for part of the week, thereby cutting utility costs.
Suppose a business budgets its annual overhead at 75,000 for the accounting period. The business applies overhead to its products using direct labor hours as the absorption base, and budgets for 30,000 direct labor hours for the same accounting period. Overhead absorption is a process by which overheads are included in the total cost of a product. According to Terminology of Cost Accountancy overhead absorption is defined as “the charging overheads to cost units by means of rates separately calculated for each cost centre.
Blanket absorption rate is used in relation to the recovery or absorption of overheads. This method also assumes the predominance of direct labor and ignores all other production factors. Absorption of the overhead reflects the number of hours involving direct labor. In some industries, companies might want to calculate the overhead cost per employee, perhaps to make staffing decisions, analyze team profitability, set prices, or make budgeting decisions.
