For each direct labor hour worked on a job, $4.00 of factory overhead will be

applied to the job.

Journal Entries

Page 21: Ch 05 Job Costing

Handout 5(a) Job order costing; overhead allocation; journal entries Deltoid Exercise Apparati, Inc. installs weight training equipment in health

clubs and private homes. The firm uses job order costing, and applies overhead

to specific jobs using a predetermined overhead rate (“normal” costing).

Deltoid uses direct labor dollars as a basis for setting a predetermined overhead

rate for the period. The firm has budgeted total direct labor costs of $1,200,000

and budgeted total overhead costs are $2,400,000. The firm had no beginning

inventories and experienced the following transactions and events in the current

period.

Provide journal entries to reflect the following events.(Note that the

predetermined overhead rate is 200% of direct labor dollars.)

Page 22: Ch 05 Job Costing

(a) The firm purchased materials for $1,200,000. Of this amount, $800,000

was charged to job cards as direct materials, and $200,000 was charged

as indirect materials to factory overhead.

Page 23: Ch 05 Job Costing

(a) The firm purchased materials for $1,200,000. Of this amount, $800,000 was

charged to job cards as direct materials, and $200,000 was charged as indirect

materials to factory overhead.

Dr. Materials inventory $1,200.000

Cr. Accounts payable $1,200,000

Dr. Work in process (direct materials) $800,000

Dr. Overhead control $200,000

Cr. Materials inventory $1,000,000

Page 24: Ch 05 Job Costing

(b) Total payroll expenses for the period were $2,400,000,

comprised of $1,600,000 of direct labor charged to job cards,

and $800,000 of indirect labor charged to factory overhead.

Page 27: Ch 05 Job Costing

(a) Direct labor costs of $400,000 are included in the ending work-in-process

inventory, and direct labor costs of $200,000 are included in the ending

finished goods inventory.

This information implies that the remaining direct labor costs of

$1,000,000 are included in cost of goods sold. In addition,

applied overhead equal to 200% of direct labor is included in

each of these three accounts (ending work in process, finished

goods and cost of goods sold).

(b) Direct material costs of $200,000 are included in the ending work-in-process

inventory, and direct material costs of $100,000 are included in the ending

finished goods inventory.

This information implies that $500,000 of direct materials are included in cost of goods sold.

Page 28: Ch 05 Job Costing

Because there were no beginning inventories, and we know the amounts of direct materials, labor, and applied overhead during the period, as well as the ending balances in the inventories and cost of goods sold, we can determine the current manufacturing costs, cost of goods completed, over/ under applied overhead, and cost of goods sold. This information is shown in T- accounts below.

(h) Cost of sales is recognized before disposition of the overhead variance:

Dr. Cost of goods sold $3.500,000

Cr. Finished goods $3.500,000

Page 31: Ch 05 Job Costing

Disposition of the overhead variance:

(1) Assume that overhead variances are charged (or credited) to cost of

goods sold, and determine: (a) valuation of the ending inventories; (b) cost of goods

sold; and (c) gross margin for the period. Provide a journal entry to close the overhead

variance balance.

Page 32: Ch 05 Job Costing

Disposition of the overhead variance:

(1) Assume that overhead variances are charged (or credited) to cost of

goods sold, and determine: (a) valuation of the ending inventories; (b) cost of goods

sold; and (c) gross margin for the period. Provide a journal entry to close the overhead

variance balance.

If the entire overhead variance is credited to cost of goods sold, the

ending inventory valuations are as shown above (in the T-accounts),

and the cost of sales is reduced from $3,500,000 to $2,900,000.

Gross margin is $100,000 (sales of $3,000,000 less cost of sales of

$2,900,000).The journal entry is as follows:

Dr. Overhead control $600,000

Cr. Cost of goods sold $600,000

Page 33: Ch 05 Job Costing

Re-do the calculations required in part (2) above assuming that Deltoid’s overhead variances are pro-rated to inventories and cost of sales based upon the amounts of applied overhead in the ending balances in these accounts (before the variances and the revenue and expense accounts are closed).

2. Assume that the company develops separate plant-wide overhead rates for variable and fixed overheads. Determine the predetermined rates, the applied overheads, and the amounts of over-/under-applied overhead for both variable and fixed overhead.

Variable overhead: PVOHR = Budgeted variable overhead / Budgeted DLH = $800,000 / 200,000DLH = $4.00 Applied VOH = PVOHR x Actual DLH = $4.00 x 220,000DLH = $880,000 Under/over applied variable overhead = Actual VOH – Applied VOH = $900,000 - $880,000 = $20,000 under-applied

Fixed overhead: PFOHR = Budgeted fixed overhead / Budgeted DLH = $600,000 / 200,000DLH = $3.00 Applied FOH = PFOHR x Actual DLH = $3.00 x 220,000DLH = $660,000 Under/over applied fixed overhead = Actual FOH – Applied FOH = $600,000 - $660,000 = $60,000 over-applied

Note: The under-applied variable overhead of $20,000 plus the over-applied fixed overhead of $60,000 add

up to the total over-applied overhead of $40,000 determined using the combined rate in part 1, above.

4. Contrast the total amounts of applied overheads and over-/under absorbed overheads that you determined in answering the questions above. Which amounts provide more useful information to managers?

Note that the actual total overhead for the two departments combined is

$1,500,000, and the total applied overhead is $1,225,000. The total under-applied

overhead is therefore $275,000. This reveals a significantly more negative variance

than was apparent using a single plant-wide rate to absorb overhead. The underlying

reason for the disparate measurements is because the overhead rates differ

substantially between the departments, and the department with the higher rate had

lower production (fewer labor hours) than were budgeted. Consequently, that higher-

rate department should have had a large reduction in variable overhead spending, but

that reduction apparently was not realized.

5. Assume that the company is developing a bid price for a special customer order. The project is estimated to require 20,000 direct labor hours. Determine the total variable overhead that would be estimated for the project based on plant-wide and departmental overhead rates, under each of the following assumptions:

(a) The 20,000 required direct labor hours would consist of

16,000 hours in Department A and 4,000 hours in Department B. Explain any difference between the overhead assignments using plant-wide vs. departmental rates.

Determine the total variable overhead that would be estimated for the project based on plant-wide and departmental overhead rates, under each of the following assumptions:

(a) The 20,000 required direct labor hours would consist of

16,000 hours in Department A and 4,000 hours in Department B. Explain any difference between the overhead assignments using plant-wide vs. departmental rates.

First, we determine that the departmental variable overhead rate is $1.25 in Department A ($200,000 / 160,000DLH), and is $15.00 in Department B ($600,000 / 40,000DLH).

Dept. A Dept. B Plant-wide Budgeted amounts at the start of the year: Fixed overhead $ 200,000 $ 400,000 $ 600,000 Variable overhead Direct labor hours

$ 200,000 160,000DLH

$ 600,000 40,000DLH

$ 800,000 200,000DLH

Actual amounts determined at the end of the year: Fixed overhead $ 200,000 $ 400,000 $ 600,000 Variable overhead Direct labor hours

Determine the total variable overhead that would be estimated for the project based on plant-wide and departmental overhead rates, under each of the following assumptions:

(a) The 20,000 required direct labor hours would consist of

16,000 hours in Department A and 4,000 hours in Department B. Explain any difference between the overhead assignments using plant-wide vs. departmental rates.

First, we determine that the departmental variable overhead rate is $1.25 in Department A ($200,000 / 160,000DLH), and is $15.00 in Department B ($600,000 / 40,000DLH).

Plant-wide rate: 20,000DLH x $4.00 = $80,000 Departmental rates: A: 16,000DLH x $1.25 = $20,000 B: 4,000DLH x $15.00 = $60,000 TOTAL = $80,000 There is no difference in the two estimates of variable overhead because the required labor

hours are distributed across the two departments in the same proportions as are the plant-wide

labor hours. Note that 80% (20%) of the plant-wide total labor hours are budgeted for

Department A (B). The special customer order also requires 80% (20%) of its labor hours in

Department A (B).

Page 49: Ch 05 Job Costing

(b) The 20,000 required direct labor hours would consist of 10,000 hours in Department A and 10,000 hours in Department B. Explain any difference between the overhead assignments using plant-wide vs. departmental rates.

Plant-wide rate: 20,000DLH x $4.00 = $80,000 Departmental rates: A: 10,000DLH x $1.25 = $ 12,500 B: 10,000DLH x $15.00 = $150,000 TOTAL = $162,500

In this case, the required labor hours are disproportionately incurred in the

higher-cost department. Because of this feature, the use of departmental rates

will provide a substantially higher estimate of variable overhead. Use of a plant-

wide overhead rate would result in an under-estimate of variable overhead in the

amount of $82,500 ($162,500 - $80,000).

6. Assume that the company has entered a “cost plus” contract with the U.S. government that provides re-imbursement of full (i.e., fixed plus variable) costs plus a mark-on of 25% above cost. The contract is expected to require 40,000 direct labor hours. Determine the total overhead reimbursement that would be received for this contract based on plant-wide and departmental overhead rates, under each of the following assumptions:

(a) The 40,000 required direct labor hours would consist of 32,000 hours in

Department A and 8,000 hours in Department B. Explain any difference between the overhead assignments using plant-wide vs. departmental rates.

Dept. A Dept. B Plant-wide Budgeted amounts at the start of the year: Fixed overhead $ 200,000 $ 400,000 $ 600,000 Variable overhead Direct labor hours

$ 200,000 160,000DLH

$ 600,000 40,000DLH

$ 800,000 200,000DLH

Actual amounts determined at the end of the year: Fixed overhead $ 200,000 $ 400,000 $ 600,000 Variable overhead Direct labor hours

$ 300,000 190,000DLH

$ 600,000 30,000DLH

The contract is expected to require 40,000 direct labor hours. Determine the total overhead reimbursement that would be received for this contract based on plant-wide and departmental overhead rates, under each of the following assumptions:

(a) The 40,000 required direct labor hours would consist of 32,000 hours in

Department A and 8,000 hours in Department B. Explain any difference between the overhead assignments using plant-wide vs. departmental rates.

(a) The 40,000 required direct labor hours would consist of 32,000 hours in Department A and 8,000 hours in Department B. Explain any difference between the overhead assignments using plant-wide vs. departmental rates.

Plant-wide rate: 40,000DLH x $7.00 = $280,000 Departmental rates: A: 32,000DLH x $2.50 = $80,000 B: 8,000DLH x $25.00 = $200,000 TOTAL = $280,000 There is no difference in the two estimates of overhead because the required labor

hours are distributed across the two departments in the same proportions as are the

plant-wide labor hours. Note that 80% (20%) of the plant-wide total labor hours are

budgeted for Department A (B). The government contract also requires 80% (20%) of

its labor hours in Department A (B).

Page 52: Ch 05 Job Costing

(b) The 40,000 required direct labor hours would consist of 15,000 hours in Department A and 25,000 hours in Department B. Explain any difference between the overhead assignments using plant-wide vs. departmental rates.

Plant-wide rate: 40,000DLH x $7.00 = $280,000 Departmental rates: A: 15,000DLH x $2.50 = $37,500 B: 25,000DLH x $25.00 = $625,000 TOTAL = $662,500

In this case, the required labor hours are disproportionately incurred in the higher-

cost department. Because of this feature, the use of departmental rates will provide

a substantially higher application of overhead to the government contract. Use of a

plant-wide overhead rate would result in a lower application of overhead in the

amount of $382,500 ($662,500 - $280,000). Because costs are reimbursed at a 25%

mark-up, the company would receive a lower reimbursement in the amount of

$478,125 ($382,500 x 125%) if the plant-wide overhead rate were used to cost the

contract.

3. Darrow Company uses a predetermined overhead rate based on direct labor-hours to apply manufacturing overhead to jobs. Last year, the company worked 10,000 direct labor-hours and incurred $80,000 of actual manufacturing overhead cost. If overhead was underapplied by $2,000, the predetermined overhead rate for the company for the year must have been: A. $7.80 B. $8.00 C. $8.20 D. $8.40

3. Darrow Company uses a predetermined overhead rate based on direct labor-hours to apply manufacturing overhead to jobs. Last year, the company worked 10,000 direct labor-hours and incurred $80,000 of actual manufacturing overhead cost. If overhead was underapplied by $2,000, the predetermined overhead rate for the company for the year must have been: A. $7.80 B. $8.00 C. $8.20 D. $8.40

Actual overhead of $80,000 is underapplied by $2,000 so applied overhead is $78,000. The activity is 10,000dlh, implying a POHR of $7.80 ($78,000 / 10,000).
