Question 1

A company is automating its factory. The new equipment will cause estimated annual fixed manufacturing overhead to increase from $300,000 to $500,000. Because fewer workers are needed, estimated annual direct labor hours are expected to decrease from 20,000 to 10,000. Variable overhead per direct labor hour is expected to remain the same at $5.00. The company uses direct labor hours as its allocation base. What will be the effect of these changes on the predetermined overhead rate?

  1. It will decrease by $5.00 per hour.
  2. It will remain the same.
  3. It will increase by $20.00 per hour.
  4. It will increase by $35.00 per hour. (correct answer)
Explanation: Calculate the POR before and after the change. Before: Total Estimated MOH = Fixed MOH + Variable MOH = $300,000 + (20,000 DLH * $5.00/DLH) = $300,000 + $100,000 = $400,000. Old POR = $400,000 / 20,000 DLH = $20.00 per DLH. After: Total Estimated MOH = $500,000 + (10,000 DLH * $5.00/DLH) = $500,000 + $50,000 = $550,000. New POR = $550,000 / 10,000 DLH = $55.00 per DLH. The effect is an increase of $55.00 - $20.00 = $35.00 per hour.

Question 2

For a particular job, Gemini Corp. incurred $4,000 in direct material costs and $6,000 in direct labor costs. The job required 300 machine hours to complete. The company's budget for the year included total manufacturing overhead of $500,000, total direct labor costs of $800,000, and total machine hours of 20,000. Gemini uses machine hours as its allocation base. What is the total manufacturing cost of this job?

  1. $13,750
  2. $17,500 (correct answer)
  3. $10,000
  4. $21,250
Explanation: First, calculate the POR using the specified allocation base (machine hours). POR = Estimated MOH / Estimated Machine Hours = $500,000 / 20,000 MH = $25 per MH. Second, apply this overhead to the job. Applied OH = $25/MH * 300 MH = $7,500. Third, calculate the total manufacturing cost of the job, which is the sum of direct materials, direct labor, and applied manufacturing overhead. Total Job Cost = DM + DL + Applied MOH = $4,000 + $6,000 + $7,500 = $17,500.

Question 3

A company is considering switching its overhead allocation base from 40,000 estimated direct labor hours to 25,000 estimated machine hours. Total estimated overhead is $200,000. A particular product, Job #88, requires 8 direct labor hours and 6 machine hours. What would be the difference in overhead allocated to Job #88 if the company switches from the direct labor hour base to the machine hour base?

  1. $8.00 increase (correct answer)
  2. $8.00 decrease
  3. $3.00 increase
  4. $2.00 decrease
Explanation: Step 1: Calculate the POR under both methods. DLH POR = $200,000 / 40,000 DLH = $5.00 per DLH. MH POR = $200,000 / 25,000 MH = $8.00 per MH. Step 2: Apply both rates to Job #88. OH on DLH basis = $5.00 * 8 DLH = $40. OH on MH basis = $8.00 * 6 MH = $48. Step 3: Find the difference. The switch results in an increase of $48 - $40 = $8.00.

Question 4

A company budgeted $450,000 of manufacturing overhead and 30,000 direct labor hours. Actual results were $472,000 of manufacturing overhead and 32,000 direct labor hours. A specific job completed during the period required 50 direct labor hours. How much more or less overhead would be allocated to this job if an actual overhead rate had been used instead of a predetermined rate?

  1. $12.50 more would be allocated
  2. $12.50 less would be allocated (correct answer)
  3. $25.00 more would be allocated
  4. $25.00 less would be allocated
Explanation: First, calculate the overhead allocated using the predetermined rate (Normal Costing). Predetermined Rate = Budgeted MOH / Budgeted DLH = $450,000 / 30,000 DLH = $15.00 per DLH. Overhead applied to the job = $15.00 * 50 DLH = $750.00. Second, calculate the overhead that would be allocated using an actual rate (Actual Costing). Actual Rate = Actual MOH / Actual DLH = $472,000 / 32,000 DLH = $14.75 per DLH. Overhead allocated to the job on this basis = $14.75 * 50 DLH = $737.50. The difference is $750.00 - $737.50 = $12.50. Therefore, $12.50 less would be allocated using an actual rate.

Question 5

Orion Industries calculates its predetermined overhead rate on an annual basis. For the current year, estimated total manufacturing overhead is $1,200,000, and estimated total machine hours are 60,000. In March, the company incurred actual manufacturing overhead of $105,000 and worked 5,200 machine hours. How much manufacturing overhead was applied to production during the month of March?

  1. $100,000
  2. $104,000 (correct answer)
  3. $105,000
  4. $108,333
Explanation: First, calculate the annual predetermined overhead rate. POR = Annual Estimated MOH / Annual Estimated Activity = $1,200,000 / 60,000 MH = $20 per MH. This rate is used for the entire year. To find the overhead applied in March, multiply this annual POR by the actual machine hours worked in March. Applied OH for March = $20/MH * 5,200 MH = $104,000. The actual overhead for March ($105,000) and any monthly calculations of the rate are irrelevant.

Question 6

Stellar Corp. uses a predetermined overhead rate of $18.50 per machine hour. The company's budget for the period was based on 10,000 machine hours. During the period, the company actually worked 11,000 machine hours and incurred actual manufacturing overhead costs of $205,000. What is the total manufacturing overhead applied to Work in Process during the period?

  1. $185,000
  2. $203,500 (correct answer)
  3. $205,000
  4. $223,500
Explanation: Applied overhead is calculated by multiplying the predetermined overhead rate by the actual amount of the allocation base incurred. The POR is $18.50 per machine hour, and the actual machine hours worked were 11,000. Therefore, Applied Overhead = $18.50 * 11,000 = $203,500. The budgeted machine hours (10,000) are used to calculate the POR, not to apply it. The actual manufacturing overhead cost ($205,000) is used to determine if overhead is over- or under-applied, but it is not the amount of overhead applied to production.

Question 7

Apex Manufacturing budgets the following costs for the upcoming year: Direct materials, $250,000; Direct labor, $400,000; Factory depreciation, $120,000; Factory utilities, $80,000; Indirect labor, $50,000; Sales commissions, $60,000; and Administrative salaries, $90,000. The company plans to operate at a level of 50,000 direct labor hours. What is the company's predetermined overhead rate per direct labor hour?

  1. $5.00 (correct answer)
  2. $6.20
  3. $8.00
  4. $20.00
Explanation: The predetermined overhead rate (POR) is calculated as: Estimated Total Manufacturing Overhead / Estimated Allocation Base. First, identify and sum the estimated manufacturing overhead (MOH) costs: Factory depreciation ($120,000) + Factory utilities ($80,000) + Indirect labor ($50,000) = $250,000. Sales commissions and administrative salaries are period costs, not product costs, so they are excluded. Direct materials and direct labor are also excluded as they are not overhead. The estimated allocation base is 50,000 direct labor hours. Therefore, the POR = $250,000 / 50,000 DLH = $5.00 per DLH.

Question 8

Over the last two years, Caspian Corp. has observed the following manufacturing overhead costs at two activity levels. In Year 1, at 10,000 machine hours, costs were $180,000. In Year 2, at 15,000 machine hours, costs were $230,000. The company plans to operate at 12,000 machine hours in the upcoming year and will use the high-low method to create a cost formula. What will be the predetermined overhead rate for the upcoming year?

  1. $10.00 per machine hour
  2. $15.33 per machine hour
  3. $16.67 per machine hour
  4. $17.50 per machine hour (correct answer)
Explanation: This is a multi-step problem. First, use the high-low method to find the cost formula. Variable rate = (High Cost - Low Cost) / (High Activity - Low Activity) = ($230,000 - $180,000) / (15,000 - 10,000) = $50,000 / 5,000 MH = $10 per MH. Fixed cost = Total Cost - Variable Cost = $230,000 - ($10 * 15,000) = $80,000. Second, use this formula to estimate total MOH for the budgeted activity level of 12,000 MH. Estimated MOH = $80,000 + ($10 * 12,000) = $210,000. Third, calculate the POR. POR = Estimated MOH / Estimated Activity = $210,000 / 12,000 MH = $17.50 per machine hour.

Question 9

The total manufacturing cost for Job #123 was $8,400. Direct materials charged to the job were $2,000. The company applies manufacturing overhead at a rate of 150% of direct labor cost. What was the amount of manufacturing overhead applied to Job #123?

  1. $2,560
  2. $5,600
  3. $6,400
  4. $3,840 (correct answer)
Explanation: This problem requires algebra. Total Manufacturing Cost = Direct Materials (DM) + Direct Labor (DL) + Manufacturing Overhead (MOH). We are given: $8,400 = $2,000 + DL + MOH. We also know that MOH = 1.5 * DL. We can substitute this into the first equation: $8,400 = $2,000 + DL + (1.5 * DL). This simplifies to $6,400 = 2.5 * DL. Solving for DL: DL = $6,400 / 2.5 = $2,560. The question asks for the MOH applied, not the DL cost. MOH = 1.5 * DL = 1.5 * $2,560 = $3,840.

Question 10

Rocky Mountain Products uses a predetermined overhead rate based on direct labor dollars. The rate was set at 180% of direct labor cost based on estimated overhead of $648,000. During the current period, Job Alpha incurred direct labor costs of $5,400, Job Beta incurred $8,100, and Job Charlie incurred $3,600. If Jobs Alpha and Charlie were completed but only Job Alpha was delivered to the customer, what amount of applied overhead remains in Finished Goods inventory?

  1. $6,480 (correct answer)
  2. $9,720
  3. $14,580
  4. $30,780
Explanation: Applied overhead for each job: Alpha = $5,400 × 180% = $9,720; Beta = $8,100 × 180% = $14,580; Charlie = $3,600 × 180% = $6,480. Job Alpha was delivered (moved to COGS), Job Beta remains in WIP, and Job Charlie remains in Finished Goods. Therefore, applied overhead in Finished Goods = $6,480 (Job Charlie only). Choice B shows Job Alpha's overhead. Choice C shows Job Beta's overhead. Choice D shows total applied overhead for all jobs.

Question 11

At the end of the fiscal year, Galileo Corp. reported actual manufacturing overhead of $410,000 and actual direct labor hours of 20,000. The company's records show that manufacturing overhead was over-applied by $10,000 for the year. What predetermined overhead rate per direct labor hour was in effect during the year?

  1. $20.00
  2. $20.50
  3. $21.00 (correct answer)
  4. $21.50
Explanation: This problem requires working backwards from the over-applied overhead amount. Over-applied overhead means that the overhead applied to Work in Process is greater than the actual overhead incurred. The relationship is: Applied MOH - Actual MOH = Over-applied amount. We can find the Applied MOH: Applied MOH - $410,000 = $10,000, which means Applied MOH = $420,000. The formula for applied overhead is POR * Actual Activity. So, $420,000 = POR * 20,000 DLH. Solving for the POR: POR = $420,000 / 20,000 DLH = $21.00 per DLH.

Question 12

At the beginning of the year, Dalton Industries estimated manufacturing overhead would be $600,000 and the allocation base would be 40,000 machine hours. At the end of the year, actual manufacturing overhead was $635,000 and actual machine hours were 42,000. What was the status of manufacturing overhead at year-end?

  1. $5,000 over-applied
  2. $5,000 under-applied (correct answer)
  3. $35,000 over-applied
  4. $35,000 under-applied
Explanation: This is a three-step problem. Step 1: Calculate the POR. POR = Estimated MOH / Estimated Activity = $600,000 / 40,000 MH = $15.00 per MH. Step 2: Calculate applied overhead. Applied OH = POR * Actual Activity = $15.00 * 42,000 MH = $630,000. Step 3: Compare actual and applied overhead. Actual MOH ($635,000) > Applied MOH ($630,000). The difference is $5,000. Since actual overhead is greater than applied overhead, the overhead is under-applied by $5,000.

Question 13

Vanguard Machining applies overhead based on machine hours. The company's predetermined overhead rate is $22 per machine hour. During July, the company applied $187,000 in manufacturing overhead to its jobs. The company had budgeted 8,000 machine hours for July, but actual manufacturing overhead costs were $190,000. How many actual machine hours were worked in July?

  1. 8,000 hours
  2. 8,500 hours (correct answer)
  3. 8,636 hours
  4. 8,750 hours
Explanation: The formula for applied overhead is: Applied OH = POR * Actual Activity. We are given the Applied OH ($187,000) and the POR ($22 per machine hour). We can solve for the actual machine hours: Actual Machine Hours = Applied OH / POR = $187,000 / $22 = 8,500 hours. The budgeted hours (8,000) and actual overhead cost ($190,000) are distractors.

Question 14

A company has two production departments: Machining and Assembly. The Machining department bases its predetermined overhead rate on machine hours, while the Assembly department bases its rate on direct labor hours. Budgeted data for the year is as follows: Machining MOH $500,000, Machine Hours 25,000; Assembly MOH $300,000, Direct Labor Hours 20,000. Job #451 used 50 machine hours in Machining and 30 direct labor hours in Assembly. What is the total overhead applied to Job #451?

  1. $1,450 (correct answer)
  2. $1,600
  3. $1,750
  4. $2,050
Explanation: This requires calculating and applying two separate departmental rates. Machining POR = $500,000 / 25,000 MH = $20 per MH. Assembly POR = $300,000 / 20,000 DLH = $15 per DLH. Now, apply these rates to Job #451's activity: Machining OH Applied = $20/MH * 50 MH = $1,000. Assembly OH Applied = $15/DLH * 30 DLH = $450. Total OH Applied = $1,000 + $450 = $1,450.

Question 15

Triton Industries uses a flexible budget to estimate its manufacturing overhead costs, with the formula: Total MOH = $200,000 + $5.00 per direct labor hour. The company expects to operate at 80,000 direct labor hours for the upcoming year. What is the predetermined overhead rate per direct labor hour?

  1. $5.00
  2. $2.50
  3. $7.50 (correct answer)
  4. $6.25
Explanation: First, calculate the total estimated MOH at the expected activity level. Total Estimated MOH = $200,000 + ($5.00 * 80,000 DLH) = $200,000 + $400,000 = $600,000. Second, calculate the POR by dividing the total estimated MOH by the estimated activity level. POR = $600,000 / 80,000 DLH = $7.50 per DLH.

Question 16

A company has a theoretical capacity of 100,000 machine hours and a practical capacity of 80,000 machine hours per year. Budgeted annual manufacturing overhead is $500,000. The company's policy is to base its predetermined overhead rate on practical capacity. During the year, the company actually worked 78,000 machine hours. What was the total overhead applied during the year?

  1. $390,000
  2. $625,000
  3. $500,000
  4. $487,500 (correct answer)
Explanation: First, calculate the predetermined overhead rate using the specified capacity level. The policy is to use practical capacity. POR = Budgeted MOH / Practical Capacity = $500,000 / 80,000 MH = $6.25 per MH. The theoretical capacity is irrelevant information. Second, apply this rate to the actual machine hours worked. Applied Overhead = POR * Actual MH = $6.25 * 78,000 MH = $487,500.

Question 17

At the start of the year, a company established its predetermined overhead rate based on $800,000 of estimated overhead and 50,000 estimated machine hours. In June, a major new customer order caused the company to revise its annual estimates to $900,000 of overhead and 60,000 machine hours. For the year, the company's actual results were 58,000 machine hours. What is the total overhead applied for the year?

  1. $870,000
  2. $928,000 (correct answer)
  3. $900,000
  4. $880,000
Explanation: The predetermined overhead rate is established at the beginning of the year and is used throughout the year to maintain consistency. It is not changed mid-year due to revised estimates. The original POR = $800,000 / 50,000 MH = $16.00 per MH. This rate is applied to the actual machine hours for the year. Applied Overhead = POR * Actual Activity = $16.00/MH * 58,000 MH = $928,000. The revised estimates and other data are distractors.

Question 18

Hydra Corp. plans to produce 80,000 units of its product next year. Each unit requires 0.25 machine hours to produce. Budgeted manufacturing overhead for the year is $300,000. The company uses machine hours as its overhead allocation base. What is the predetermined overhead rate per machine hour?

  1. $3.75
  2. $4.00
  3. $15.00 (correct answer)
  4. $0.067
Explanation: This is a two-step problem. First, calculate the total estimated amount of the allocation base (machine hours). Total Estimated MH = 80,000 units * 0.25 MH/unit = 20,000 MH. Second, use this to calculate the predetermined overhead rate. POR = Estimated MOH / Estimated MH = $300,000 / 20,000 MH = $15.00 per machine hour. A common error is to divide the overhead by the number of units, which would give $3.75.

Question 19

Lyra Corp. estimates it will incur $750,000 in manufacturing overhead costs next year. The company's primary cost driver is direct labor cost. The budget includes 25,000 direct labor hours at an average wage rate of $24 per hour. What is Lyra's predetermined overhead rate?

  1. $30.00 per direct labor hour
  2. 125% of direct labor cost (correct answer)
  3. 80% of direct labor cost
  4. 3.125% of direct labor cost
Explanation: The allocation base is direct labor cost, not direct labor hours. First, calculate the total estimated direct labor cost for the year. Total DL Cost = 25,000 DLH * $24/DLH = $600,000. Second, calculate the predetermined overhead rate as a percentage of direct labor cost. POR = (Estimated MOH / Estimated DL Cost) * 100% = ($750,000 / $600,000) * 100% = 1.25 * 100% = 125% of direct labor cost.

Question 20

Southwest Fabrication calculated a predetermined overhead rate of $35 per machine hour based on estimated overhead of $875,000. During the year, 24,500 machine hours were actually used, and actual overhead costs were $847,500. At year-end, the Applied Overhead account shows a balance of $857,500. What was the estimated machine hour capacity used to calculate the predetermined overhead rate?

  1. 24,214 machine hours
  2. 25,000 machine hours (correct answer)
  3. 24,500 machine hours
  4. 25,071 machine hours
Explanation: This question tests your understanding of predetermined overhead rates and the relationship between estimated costs, estimated activity levels, and the calculated rate itself. When you see a predetermined overhead rate problem, remember the fundamental formula: Predetermined OH Rate=Estimated Overhead CostsEstimated Activity Level\text{Predetermined OH Rate} = \frac{\text{Estimated Overhead Costs}}{\text{Estimated Activity Level}} To find the estimated machine hour capacity, you need to rearrange this formula: Estimated Activity Level=Estimated Overhead CostsPredetermined OH Rate\text{Estimated Activity Level} = \frac{\text{Estimated Overhead Costs}}{\text{Predetermined OH Rate}} Substituting the given values: Estimated Machine Hours=$875,000$35 per machine hour=25,000 machine hours\text{Estimated Machine Hours} = \frac{\$875,000}{\$35 \text{ per machine hour}} = 25,000 \text{ machine hours} The correct answer is B) 25,000 machine hours. Now let's examine why the other options are incorrect. Choice A (24,214) might result from incorrectly dividing actual overhead costs (847,500)bythepredeterminedrate(847,500) by the predetermined rate (35). Choice C (24,500) is a trap—this represents the actual machine hours used during the year, not the estimated capacity used in the rate calculation. Choice D (25,071) could come from dividing the applied overhead balance ($857,500) by the predetermined rate. The key insight is that predetermined overhead rates are calculated at the beginning of the period using estimates, regardless of what actually happens during the year. When solving predetermined overhead rate problems, always identify which figures are estimates (used in rate calculation) versus actual results (used for variance analysis). Focus on the estimated amounts when working backward to find the original capacity assumption.
