Job-Order Costing

A job order costing system is used when a company produces a product or provides a service that is unique-that is, the cost of one product or service is different than that of another.

A job order costing system must be able to identify each individual job and accumulate its costs separately from the costs of other jobs. In manufacturing, the jobs may be for a single item or a batch of similar items. The flowchart illustrates the flow of costs into Work in Process and Finished Goods in a job order costing system.

Materials are recorded to jobs based on a materials requisition and labor is charged to jobs based on a timecard, or labor accumulation system.

The rate may be based on direct labor hours, machine hours, or another activity. It may be a dollar amount or a percentage.

Assume the company has estimated overhead costs for the coming year of $1,138,800 and expected activity is 94,900 direct labor hours.

The formula for calculating the overhead rate is:

Overhead rate =	Estimated overhead costs	=	$
	Activity		direct labor hours
			= $ per direct labor hour

Overhead is applied to jobs based on this rate. It is likely that the actual overhead costs and activity level will be different than the estimated overhead cost and estimated activity level. The result is an amount of over/under applied overhead that is expensed to cost of goods sold.

At the beginning of the year, Carentan Company estimated the following:

	Machining Department	Assembly Department	Total
Overhead	$372,400	$263,520	$635,920
Direct labor hours	110,000	164,700	274,700
Machine hours	186,200	-	186,200

Carentan uses departmental overhead rates. In the machining department, overhead is applied on the basis of machine hours. In the assembly department, overhead is applied on the basis of direct labor hours. Actual data for the month of January are as follows:

	Machining Department	Assembly Department	Total
Overhead	$28,556	$21,316	$49,872
Direct labor hours	8,240	12,400	20,640
Machine hours	14,860	-	14,860
