4-33 Job costing; actual, normal, and variation from normal costing. Cheney & Partners,
a Quebec-based public accounting partnership, specializes in audit services. Its job-costing
system has a single direct-cost category (professional labor) and a single indirect-cost pool
(audit support, which contains all costs of the Audit Support Department). Audit support
costs are allocated to individual jobs using actual professional labor-hours. Cheney &
Partners employs 10 professionals to perform audit services.
Budgeted and actual amounts for 2017 are as follows:
Required:
1. Compute the direct-cost rate and the indirect-cost rate per professional labor-hour for 2017
under (a) actual costing, (b) normal costing, and (c) the variation from normal costing that
uses budgeted rates for direct costs.
2. Which job-costing system would you recommend Cheney & Partners use? Explain.
3. Cheney’s 2017 audit of Pierre & Co. was budgeted to take 170 hours of professional labor
time. The actual professional labor time spent on the audit was 185 hours. Compute the cost
of the Pierre & Co. audit using (a) actual costing, (b) normal costing, and (c) the variation
from normal costing that uses budgeted rates for direct costs. Explain any differences in the
job cost.

Solutions designs Web pages for clients in the education sector. The company’s job-costing
system has a single direct cost category (Web-designing labor) and a single indirect cost pool
composed of all overhead costs. Overhead costs are allocated to individual jobs based on direct
labor-hours. The company employs six Web designers. Budgeted and actual information
regarding Creative Solutions follows:
Required:
1. Compute the direct-cost rate and the indirect-cost rate per Web-designing labor-hour for 2017
under (a) actual costing, (b) normal costing, and (c) the variation from normal costing that
uses budgeted rates for direct costs.
2. Which method would you suggest Creative Solutions use? Explain.
3. Creative Solutions’ Web design for Greenville Day School was budgeted to take 86 direct
labor-hours. The actual time spent on the project was 79 hours. Compute the cost of the
Greenville Day School job using (a) actual costing, (b) normal costing, and (c) the variation
from normal costing that uses budgeted rates for direct costs.

Proration of overhead. The Ride-On-Wave Company (ROW) produces a line of non-motorized
boats. ROW uses a normal-costing system and allocates manufacturing overhead using direct
manufacturing labor cost. The following data are for 2017:
Inventory balances on December 31, 2017, were as follows:
Required:
1. Calculate the manufacturing overhead allocation rate.
2. Compute the amount of under or overallocated manufacturing overhead.
3. Calculate the ending balances in work in process, finished goods, and cost of goods sold if
under or overallocated manufacturing overhead is as follows:
a. Written off to cost of goods sold
b. Prorated based on ending balances (before proration) in each of the three accounts
c. Prorated based on the overhead allocated in 2017 in the ending balances (before
proration) in each of the three accounts

4. Writing off all of the underallocated manufacturing overhead to Cost of Goods Sold (COGS)
4-36 Job costing, accounting for manufacturing overhead, budgeted rates. The Solomon
Company uses a job-costing system at its Dover, Delaware, plant. The plant has a machining
department and a finishing department. Solomon uses normal costing with two direct-cost
categories (direct materials and direct manufacturing labor) and two manufacturing overhead
cost pools (the machining department with machine-hours as the allocation base and the
finishing department with direct manufacturing labor costs as the allocation base). The 2017
budget for the plant is as follows:
Required:
1. Prepare an overview diagram of Solomon’s job-costing system.
2. What is the budgeted manufacturing overhead rate in the machining department? In the
finishing department?
3. During the month of January, the job-cost record for Job 431 shows the following:
Compute the total manufacturing overhead cost allocated to Job 431.
4. Assuming that Job 431 consisted of 400 units of product, what is the cost per unit?
5. Amounts at the end of 2017 are as follows:
Compute the under- or overallocated manufacturing overhead for each department and for
the Dover plant as a whole.
6. Why might Solomon use two different manufacturing overhead cost pools in its job-costing
system?

in labor relations and employee-related work. It employs 30 professionals (5 partners and 25
associates) who work directly with its clients. The average budgeted total compensation per
professional for 2017 is $97,500. Each professional is budgeted to have 1,500 billable hours to
clients in 2017. All professionals work for clients to their maximum 1,500 billable hours
available. All professional labor costs are included in a single direct-cost category and are traced
to jobs on a per-hour basis. All costs of Kidman & Associates other than professional labor costs
are included in a single indirect-cost pool (legal support) and are allocated to jobs using
professional labor-hours as the allocation base. The budgeted level of indirect costs in 2017 is
$2,475,000.
Required:
1. Prepare an overview diagram of Kidman’s job-costing system.
2. Compute the 2017 budgeted direct-cost rate per hour of professional labor.
3. Compute the 2017 budgeted indirect-cost rate per hour of professional labor.
4. Kidman & Associates is considering bidding on two jobs:
a. Litigation work for Richardson, Inc., which requires 120 budgeted hours of professional
labor
b. Labor contract work for Punch, Inc., which requires 160 budgeted hours of professional
labor. Prepare a cost estimate for each job.
