Chapter 07 – Job Costing
7-12
(1) normal cost is the cost of a job determined by actual direct material and labor costs plus
overhead applied using a predetermined overhead rate and an actual allocation base,
(2) actual cost is the cost of a job determined by actual direct material and labor costs plus
overhead applied using an actual overhead rate and an actual allocation base, and
(3) standard cost is the cost of a job determined by standard (budgeted) direct material and
labor costs plus overhead applied using a predetermined overhead rate and a standard
(budgeted) allocation base.
• When over– and underapplied overhead is allocated using the overhead (or the
allocation base) in the individual accounts, the result approximates actual costing.
• Standard costing will be discussed in more detail in Chapter 16.
• The tradeoffs between actual and normal costing involve the speed, convenience, and
accuracy of the cost information. Actual costing requires management to wait until actual
costs are known but provides more current information. Normal costing is a reasonable
compromise that uses estimates only for indirect costs.
♦ The two-stage cost allocation process introduced in Chapter 6 can easily be applied to the job
costing problems in this chapter in which two or more allocation bases may be used to calculate
the associated predetermined overhead rates, one for each allocation base.
♦ In summary, a job cost is determined in six steps:
1. Select an allocation base for computing the predetermined overhead rate(s).
2. Estimate overhead for each overhead cost pool.
3. Calculate the predetermined overhead rate(s) by dividing the estimated overhead by the
estimated allocation base.
4. Record direct costs for each job as they are incurred.
5. Apply overhead using the predetermined rates as jobs are completed or when the
financial statements are prepared.
6. If there is over- or underapplied overhead, either write it off directly to Cost of goods
sold or allocate it to Cost of goods sold and ending inventory accounts.
