AccountingNow: Better Understanding Of Job Costs

Accountingnow That We Have A Better Understanding Of Job Costing Let

Imagine these products and services as businesses, in which you are the manager with several teenagers as your employees. In your initial post, define the “jobs” in job costing. Explain how you would measure direct materials cost, direct labor cost, and compute predetermined overhead rates. What are your actual manufacturing overhead costs, and why aren’t they traced to jobs, just as direct materials and direct labor are traced to jobs?

Give reasons why overhead might be under-applied or over-applied in a given year. What factors should be considered in selecting a base to be used in computing the predetermined overhead rate? Why?

Job costing is an essential accounting method used to determine the costs associated with individual jobs or projects within a business. It is particularly relevant in industries where products or services are unique or customized, such as construction, manufacturing, or service industries like catering and printing. In a hypothetical scenario where a manager oversees a small enterprise, such as a neighborhood lawn mowing service run by teenagers, understanding how to identify and assign costs to specific jobs becomes crucial for pricing, profitability analysis, and cost control.

In the context of job costing, the “jobs” refer to specific projects or units of work that the business undertakes for clients or customers. For example, in a neighborhood lawn mowing business, each lawn that is mowed can be considered a separate job. Alternatively, in a craft fair setting, each craft item or booth setup might be viewed as a distinct job. Recognizing these jobs allows the business to accumulate direct costs attributable to each specific task, which helps in determining the profitability of individual jobs and in setting appropriate pricing strategies.

Measuring direct materials cost involves tracking the raw materials directly used in completing each job. In the case of a lawn mowing service, direct materials might include gasoline, mower blades, or fertilizers, depending on the services offered. These costs are accumulated based on receipts, invoices, or tracking the specific quantities of materials consumed per job. For craft sales, direct materials could be fabric, paint, or other supplies specific to each craft item.

Direct labor costs are calculated by assigning wages and benefits of employees directly involved in the execution of the job. For example, teenagers hired to mow lawns or produce crafts are paid either hourly or per task, and their wages are directly attributable to the respective jobs. In practice, time-tracking tools such as timesheets or job tickets are used to attribute labor hours precisely, ensuring that labor costs are accurately applied to each job.

Predetermined overhead rates are established before the period begins, based on estimated overhead costs and an appropriate allocation base—commonly direct labor hours, direct labor costs, or machine hours. The rate is calculated by dividing the estimated total manufacturing overhead by the estimated total units of the chosen base.

Actual manufacturing overhead costs include expenses such as rent, utilities, depreciation of equipment, and indirect labor costs—expenses that support production but are not directly traceable to a specific job. They are not traced directly to jobs because doing so would be inefficient and often impossible—these costs benefit multiple jobs and are incurred regardless of the number of units produced. Instead, overhead is allocated to jobs using predetermined rates, which simplifies accounting and provides timely cost estimates.

Overhead can be under-applied when the allocated overhead during the period is less than the actual overhead incurred. Conversely, over-applied overhead occurs when the allocated amount exceeds actual costs. Under-application may result from underestimating overhead costs or overestimating the activity base, leading to insufficient allocation. Over-application might happen due to overestimation of overhead or a decline in activity levels, causing excess overhead to be allocated to jobs.

When selecting a base for computing the predetermined overhead rate, several factors should be considered: the relationship between the base and overhead costs, the stability of the base, and the ease of measurement. For instance, direct labor hours may be suitable in labor-intensive industries, while machine hours might be more appropriate in manufacturing heavily reliant on machinery. The chosen base should have a strong causal link to the incurrence of overhead costs to ensure accurate cost allocation.

Choosing an appropriate base helps in assigning overhead costs more accurately to each job, which improves costing accuracy, profitability analysis, and pricing decisions. It also helps prevent significant under- or over-apportioning of overhead, thus reflecting the true costs associated with each product or service. Proper selection of the base, combined with periodic review and adjustment of rates, ensures effective overhead management and financial control within the business.
