However, a more realistic scenario would provide actual activity levels that are different than estimated activity levels, thereby creating overapplied and underapplied overhead for each activity. We described the disposition of overapplied and underapplied overhead in Chapter 2 “How Is Job Costing Used to Track Production Costs?”. Notice that this information includes an estimate of the level of activity for each cost driver, which is needed to calculate a predetermined rate for each activity in step 4.

The notes to the table show how the overhead rates were calculated in each case. Under the single plantwide overhead rate method, total budgeted overhead costs are divided by the chosen allocation base, such as total direct labor hours, to arrive at a single plantwide overhead rate. This rate then is applied to assign overhead costs to all products based on their actual usage of the allocation base. Kinetic Company estimates that overhead costs for the next year will be $1,600,000 for indirect labor and $400,000 for factory utilities. The company uses direct labor hours as its overhead allocation base. If 50,000 direct labor hours are planned for this next year, then the plantwide overhead rate is $.025 per direct labor hour.

The proportions reflect all of the relationships in the reciprocal method, instead of only part of the relationships as in the step-down method. The reciprocal method is more accurate than the other two methods because it fully recognizes self services and reciprocal services between service departments. However, this method is more involved because it requires the solution to simultaneous equations. System designers must remember that cost allocations affect performance evaluations, which in turn affect performance. As indicated in Chapter 1, performance evaluation systems are interactive in that they simultaneously measure and influence the behavior of the participants within the system. Solve cost allocations problems using the dual rate and single rate methods.

• C.Each department has the same rate for the same activity pool.
• While some of the activity measures may be related to production volume, other non-production volume related activity measures are also used.
• Both production volume related and non-production volume related activity measures, e.g., number of purchase orders, number of setups, etc.
• The company has direct labor expenses totaling $5 million for the same period.
• Usually, only one overhead rate is developed for each producing department, although the basis for these rates may differ between departments.
• The first step in using the departmental overhead rate method requires that overhead be traced to each of the company’s departments.

However, it does not give managers an accurate picture of product costs because the application of overhead burden rates is arbitrary and applied equally to the cost of all products. Overhead costs are not allocated to the products that actually consume the overhead activities. In the sections above, several comments were made in reference to the decision of whether to sell raw chicken or fried chicken. Management decisions concerning whether to sell a product at the split-off point or to process the product further fall into a category referred to as relevant, differential or incremental cost decisions. The key to the correct decision is to only consider the differences between the alternative courses of action. Following this decision rule, the joint costs are not relevant because they will not be different regardless of the decision to sell at the split-off point or to process the products beyond this point.

It is easier to calculate for firms with a single product offering or for firms where all departments produce similar products or have uniform cost objects. Labor CostCost of labor is the remuneration paid in the form of wages and salaries to the employees. The allowances are sub-divided broadly into two categories- direct labor involved in the manufacturing process and indirect labor pertaining to all other processes. The calculation of the plantwide overhead rate first requires gathering the following information. The production activities in the first stage and the unit of product in the second stage.

If your overhead rate is 20%, it means the business spends 20% of its revenue on producing a good or providing services. More accurate product costing, fewer cost objects, and a direct correlation to production volume. Departmental overhead rate method bookkeeping and cost pool overhead rate method. Volume-based costing system have served well since the inception of cost accounting. How­ever, remarkable changes have taken place in production methods, organisational structure, cost behaviour and magnitudes.

What are three advantages of activity-based costing over traditional volume-based allocation methods? Ease of use, more accurate product Online Accounting costing, and more effective cost control. Fewer allocation bases, ease of use, and a direct correlation to production volume.

How Do You Calculate Overhead Cost?

Allocate overhead costs to products using the departmental overhead rate method. P2 Allocate overhead costs to products using the departmental overhead rate method. The departmental overhead rate method traces costs to each department and then determines an allocation base for each department. This approach involves allocating the joint costs to products in proportion to these estimated sales values. It provides an alternative to the previous approach when the products can not be sold at the split-off point, i.e., without further processing. The net realizable value method implies that the increase in sales value from the split-off point to the time of sale is only equal to the after split-off costs. Since this is not likely to be an accurate assumption concerning the values added by the separate joint and after split-off processes, the NRV estimates of values at the split-off point are likely to be misstated.

For example, the power department uses some power and the maintenance department requires some maintenance. Reciprocal services refer to situations where two or more service departments provide services to each other.

Managerial Accounting Ch 4

Producing more of one product in the group means producing more of all products in the group. The key characteristic is that the products cannot be obtained separately.

In addition, these allocations have some rather senseless implications from the decision perspective, e.g., the company would be more profitable if it produced chickens with only breasts and wings. The denominator for the proportions of service provided from S1 to P1 and P2 is 900, not 950 and the denominator for the proportions of service provided from S2 to P1 and P2 is 250 not 300. This is because the self service hours are ignored as well as the 20 hours provided to Power.

What Are The Major Limitations Of Activity Based Costing?

Conceptually, this is the same logical argument discussed in Chapter 4 under the heading of reasons for using a predetermined overhead rate. First stage allocations may include self services and reciprocal services between service departments, as well as services to producing departments. Self service refers to situations where service departments use some of their own service.

Steps For Using Activity

Given this information, the departmental overhead rate for Department B based on machine hours is $4 per machine hour. Although it is a time-consuming process, it increases the accuracy of the overall overhead allocation process. Thus, a trade-off between time and accuracy comes in the way of using a single plantwide overhead rate or usage of cost pools. Take a minute to look over the advantages and disadvantages of activity based costing. As with all cost information, managers must be able to interpret the data and must use caution when making management decisions. Activity-based costing uses more cost pools and activity rates than other methods.

For example, each unit may require that materials be cut, or components be assembled. As mentioned earlier in this retained earnings balance sheet presentation, one of the biggest challenges is to identify the activities which cause the costs to occur.

ABC differs from using multiple departmental rates in how overhead cost pools are identified and in how overhead cost in each pool is allocated. For example, Wintax Company creates 5,000 products with Variable Cost per unit being $60 direct materials, $110 direct labor, and $40 variable overhead. In addition to the per-unit costs, the fixed overhead is $100,000. Adding the overhead to the per-unit costs completes what is absorption costing per unit.

We can also fill in the original equations for the service departments to find the reciprocal transfers. The total producing department costs, after all allocations, is equal to the total direct costs budgeted, i.e., $500,000 (See the note at the bottom of Exhibit 6-4).

Since the Power Department has already been closed, no costs are allocated from Maintenance to Power. 3) Solve the equations developed in to determine the allocations to the producing departments. Describe five methods of treating joint costs in the accounting records. Provide conceptual definitions for joint products, by-products the cost object of the plantwide overhead rate method is: and joint costs. What are the four steps used to accumulate and allocate costs in an activity-based costing method. Notice that the total activity levels presented here match the estimated activity levels presented in step 4. This was done to avoid complicating the example with overapplied and underapplied overhead.
