= $1,862,000 − $1,715,000 = $147,000
There is no under- or overallocated overhead under actual costing because overhead is
allocated under actual costing by multiplying actual manufacturing labor costs and the actual
manufacturing overhead rate. This, of course equals the actual manufacturing overhead costs. All
actual overhead costs are allocated to products. Hence, there is no under- or overallocatead
overhead.

Normal costing enables Anderson to report a job cost as soon as the job is completed,
assuming that both the direct materials and direct labor costs are known at the time of use. Once
the 900 direct labor-hours are known for the Laguna Model (June 2007), Anderson can compute
the $187,726 cost figure using normal costing. Anderson can use this information to manage the
costs of the Laguna Model job as well as to bid on similar jobs later in the year. In contrast,
Anderson has to wait until the December 2007 year-end to compute the $180,526 cost of the
Laguna Model using actual costing.
Although not required, the following overview diagram summarizes Anderson
Construction’s job-costing system.

of May. M2’s manufacturing costs up to this point, $410,000, remain as a debit balance in the
Work-in-Process Inventory account at the end of May 2007.

All three costing systems use the actual professional labor time of 120 hours. The budgeted 110
hours for the Pierre Enterprises audit job is not used in job costing. However, Chirac may have
used the 110 hour number in bidding for the audit.
The actual costing figure of $12,720 exceeds the normal costing figure of $12,360
because the actual indirect-cost rate ($48) exceeds the budgeted indirect-cost rate ($45). The
normal costing figure of $12,360 is less than the variation of normal costing (based on budgeted
rates for direct costs) figure of $12,600, because the actual direct-cost rate ($58) is less than the
budgeted direct-cost rate ($60).

The point of this part is (a) to get the definitions straight and (b) to underscore that
overhead is allocated by multiplying the actual amount of the allocation base by the budgeted
rate.

A homogeneous cost pool is one where all costs have the same or a similar cause-and6.
effect or benefits-received relationship with the cost-allocation base. Solomon likely assumes
that all its manufacturing overhead cost items are not homogeneous. Specifically, those in the
Machining Department have a cause-and-effect relationship with machine-hours, while those in
the Finishing Department have a cause-and-effect relationship with direct manufacturing labor
costs. Solomon believes that the benefits of using two cost pools (more accurate product costs
and better ability to manage costs) exceeds the costs of implementing a more complex system.
