Chapter 17 presented product costing, the schedule of cost of goods manufactured, and the an easy cost circulation of a manufacturer. In the preliminary presentation, most cost data (e.g., ending work in process inventory, etc.) were “given.” thing 18 proved how expense data are supplied in making important service decisions. How does one identify the price data for products and also services that are the end an outcome of fertile processes? The answer come this concern is complex.

Multiple persons, parts, and also processes might be necessary to bring about a deliverable output. Think about an automobile manufacturer; what is the dollar quantity of “cost” for the thousands of cars that space in various stages of perfect at the finish of a month? This chapter, and the next, will carry out a sense of how company information solution are offered to generate these important expense data. This chapter focuses on the project costing technique, and the following chapter will look more closely at process costing and other options.

Basic project Costing

Job costing (also dubbed job bespeak costing) is finest suited to those cases where goods and services are created upon receipt of a customer order, follow to client specifications, or in separate batches. For example, a delivery builder would most likely accumulate expenses for each ship produced. An plane manufacturer would discover this technique logical. Building and construction companies and home contractors would normally gravitate to a task costing approach. Each task is somewhat unique. Materials and also labor can be conveniently traced to every job, and also the price assignment logically follows.

Job Costing Example

Jack lock owns an electric contracting company, lock Electric. Jack offers a selection of products and services come clientele. Jack has four employees, a rented shop, a broad inventory of parts, and also a fleet the five business trucks. ~ above a common day, Jack will arrive in ~ the shop early and line out the day’s work assignments. About 8:00 a.m., his electricians arrive, and he provides them your assignments, and the necessary parts and equipment they will certainly need. They space then dispatched come the miscellaneous job sites.

One that Jack’s electricians is Donnie Odom. ~ above July 14, Donnie landed on the shop in ~ 8:00 a.m. He an initial spent 30 minutes acquiring his assignments and loading a organization truck with vital items to complete the day’s work. His three tasks for the day included:

Job A: Cleaning and reconnecting the electric connections and also replacing a flood irradiate atop a billboard (materials required encompass one lamp at $150).Job B: instead of the breakers on one old electrical distribution panel at an office building (materials required incorporate 20 breakers in ~ $20 each).Job C: Pulling wire for a new residence under construction (materials required include 500 feet of cable at $0.14 every foot).

Donnie effectively completed all three tasks. He spent one hour ~ above the billboard, two hrs on the electric panel, and three hrs on the residential installation. The other two hours of his 8-hour day were spent on indirect job management and travel. Throughout the day, Donnie likewise used a roll of electric tape ($3) and also a box of cable nuts (60 nuts in ~ $0.05 each). Donnie is payment $18 per hour. Donnie journey a truck and he provided a selection of tools, ladders, and other specialized equipment. Jack is paid $25 per hour, and he go not occupational on any details job. Instead, his time is spent doing inspections, acquiring permits, managing inventory, and other tasks.

How much did that “cost” to readjust the irradiate on the billboard? Obviously, the project cost had the
">direct costs
that the job; specifics Donnie’s direct labor time (one hour) and also the direct material (one lamp at $150). But, the job might not have obtained done without the shop, equipment, trucks, indirect labor time, tape, wire nuts, and also so forth. These latter items constitute the

">indirect costs
, or overhead. Exactly how are these expenses assigned to a specific job?

Tracking Labor

A logical beginning point is to particularly track job cost. Donnie, and the other electricians, fill the end a time report documenting time spent on every job, and also the time spent on other tasks:


Tracking Material

Jack keeps detailed records that the product released to each job. Once Donnie gathered up the irradiate bulbs, breakers, wire, tape, and also wire nuts on the morning of the 14th, some device needed to be in location to “check out” this material. The record that is offered for this process is dubbed a “materials request” or
">materials requisition form
. This kind will show what material is leave the easily accessible raw products stock and being put right into production. Periodically a separate kind is ready for every item, and sometimes a running list similar to the adhering to is used:


This kind provides important documentation to monitor inventory. It also reveals the the “direct material” because that the billboard task (Job A) was $150 (the light bulb). The cable nuts and also tape that could have been provided on the billboard will be faced as overhead, which is discussed later.

Although the illustrated type lists the product cost, that will not constantly be the case. Sometimes, a organization will no be particularly interested in letting employees see expense information, or price information may not be conveniently available. In one of two people case, the type will instead incorporate a part or serial number. A subsequent clerical job will be to determine the price of the certain parts that were put into production.

Tracking Overhead

Jack would have a large task at hand if the tried to everyday trace every items the overhead. For instance:

How hard would it be to monitor the “indirect material”? How plenty of wire nuts were supplied on the billboard? How countless inches of electrical tape were used? What to be the expense of this items?What about indirect labor? have to the expense of Donnie’s two hours of travel and also administrative time be spread out over the three work equally, pro-rata based on hours, or top top some various other basis? What about Jack’s time? that is supervising four electricians. Need to the price of his time it is in allocated 1/4 come each, or based on some other formula?One must likewise consider the price of rent, trucks, and also so forth. Donnie essential a ladder to range the billboard. Just how much is the “ladder cost” because that one job?

Tracking overhead is tricky. One method this is done is by utilizing a predetermined overhead rate. I think Jack sat under at the beginning of the year with his accountant. Together they carefully considered every one of the manufacturing overhead that was anticipated during the year. This consisted of the expense of Jack’s time, rent, the cost of vehicles, insurance, taxes, utilities, indirect labor, indirect materials, depreciation that long-lived assets, and so forth.

The expected total came to around $150,000. Jack figures that his four electricians will occupational a full of around 7,500 direct labor hours during the year. By comparing these 2 numbers ($150,000 and 7,500 hours), it is now possible to “model” that overhead is $20 per direct labor hour. A logical
A rate used to use manufacturing overhead to output; estimated factory overhead for a period divided by the approximated application base
">overhead application rate
is for this reason determined.

Two things should be do clear. First, overhead application is arbitrary. Jack determined to apply overhead based upon direct labor hours; this is a usual choice, however not the only choice. Some various other systematic and rational technique could have been developed. Ordinarily, one would shot to develop some correlation between the applications base and also overall cost incurrence. For instance, feet that wire offered (instead of straight labor hours) might have to be selected as the applications base. But, feet of wire used would be difficult to defend since two the Donnie’s three work did no use any wire and would no be assigned any of the organization overhead.

The allude is that some logical method needs to be provided to affix overhead prices to output, however no single choice is absolute. Price allocation necessarily involves some level of arbitrary methodology; this is neither bad nor good, the is simply reality. In part ways, costing is more of one “art” than “science,” regardless of its external appearance of mathematical precision.

Second, intend differences in between the yes, really overhead and also the amount applied to production. For instance, Jack will certainly likely discover that actual overhead is more or less than $150,000. Jack will additionally find the his electricians will more than likely work much more or less than the guess 7,500 hours. Accounting for the difference between the quantity of overhead applied to manufacturing (i.e., direct labor hours X $20 per hour rate) and also the really amount invested will be presented later in the chapter.

Job expense Sheet

The details on the day-to-day time sheet and materials requisition form can be logically moved to suitable
">job price sheets




Note the type reference to the source documents (e.g., “DTS.07.14.X5.DO” to show “daily time paper of July 14, 20X5, because that Donnie Odom”). In similar fashion, Donnie’s materials requisition kind was offered as the source paper for compiling the straight material details for every job. Overhead was used directly to the job expense sheets based ~ above the predetermined overhead application plan of $20 per straight labor hour.

Database System

Jack can maintain some or every one of his job costing mechanism manually. Or, he could use an electronic spreadsheet to prepare reports comparable to those simply illustrated. However, the electronic

is a more powerful tool. A number of commercial packages space available.

Generalizing, data are gotten in via a user-friendly input kind that consists of a number of predetermined “slots” because that entering wanted information. Because that instance, below is a data entry type for start Donnie’s time and material because that the 14th:


The advantage of the database method is that information is only entered once; it need not be moved to various other forms. The computer files have the right to be queried in many ways and generate an ext than a basic job expense report.

For instance, Jack could use the customized reports attribute to uncover all work on i m sorry billboard light bulbs were used during the past 18 months, or recognize the full direct labor hours of any employee because that a selected time interval, or identify all jobs performed for a selected client, and also so forth. Together databases carry out a an effective management tool.

Example For larger Job

Thus far, the illustration has focused only ~ above Donnie’s activities. He had fairly simple assignments top top July 14 and also was maybe to finish three separate work by himself. But, remember that Jack has actually three other electricians and many various other jobs. Few of these work may call for multiple employees and also extend over number of days. One such task was the brand-new home of Aba Obekie. This task took two electricians (Andy Axon and also Bev Bentson) three complete days to complete. The result job price sheet appeared as follows:


Moving Beyond basic Concepts

Thus far, a an easy illustration has been used. What this stops working to take into consideration are components such as these:

The sophistication of the details systems the are provided to track task costs.The debits and also credits the are essential to monitor the accumulation and applications of costs within a company’s general ledger system.The can be fried disposition that the difference between applied and also actual overhead.
