Apply Job Order And Process Costing - CPA Bar

  1. A company produces Product X in batches of 10,000 identical units on a continuous assembly line and Product Y as a custom-engineered component with unique specifications for each client order. Which costing systems are most appropriate?
    Answer: Process costing for Product X and job-order costing for Product Y Process costing suits Product X because it is produced in homogeneous batches where costs are averaged across identical units. Job-order costing suits Product Y because each unit has unique specifications requiring separate cost accumulation per order. Option A incorrectly applies job-order to a homogeneous product. Option C incorrectly uses the shared facility as the basis for selecting the same system. Option D reverses the appropriate assignment.
  2. Under process costing, what is the primary purpose of calculating equivalent units of production?
    Answer: To express partially completed units as a number of fully completed units, allowing meaningful cost per unit calculations when some units are only partially processed Equivalent units convert partially completed work-in-process into a common unit of measure comparable to fully completed units. Without this conversion, it would be impossible to calculate a meaningful cost per unit when some units in the period have only received 40% or 60% of the required processing. Option B describes the physical flow of units, not the purpose of equivalent units. Option C describes account reconciliation, which is a result of the process costing report, not the purpose of equivalent units. Option D describes predetermined overhead rate calculation, which is unrelated to equivalent units.
  3. In process costing using the weighted-average method, equivalent units of production are calculated as which of the following?
    Answer: Units completed and transferred out plus the equivalent units represented by ending work-in-process Under the weighted-average method, equivalent units of production (EUP) = Units completed and transferred out + (Ending WIP units x Percentage of completion). This formula counts all units to which costs must be assigned - those fully completed and those partially completed in ending WIP. Option A is redundant because units transferred to finished goods are the completed units. Option C ignores the contribution of partially completed ending WIP units. Option D describes the flow of physical units but not the EUP calculation.
  4. Riverdale Co. has total conversion costs to account for of $280,000 and equivalent units of production for conversion of 20,000. What is the cost per equivalent unit for conversion costs?
    Answer: $14.00 Cost per equivalent unit = Total conversion costs / EUP = $280,000 / 20,000 = $14.00. Option A divides by an incorrect equivalent unit count of approximately 23,333. Option B and Option C result from arithmetic errors using incorrect denominators.
  5. Riverdale Co. has cost per EU: materials $18.00, conversion $14.00. Ending WIP is 4,000 units (100% complete for materials, 50% complete for conversion). What is the total cost assigned to ending WIP?
    Answer: $100,000 Materials cost in ending WIP = 4,000 x 100% x $18.00 = $72,000. Conversion cost in ending WIP = 4,000 x 50% x $14.00 = $28,000. Total ending WIP cost = $72,000 + $28,000 = $100,000. Option A treats ending WIP as 100% complete for conversion as well. Option B includes only the materials component. Option D includes only the conversion component.
  6. Pinecrest Manufacturing reports: beginning WIP $45,000, direct materials added $280,000, direct labor $195,000, overhead applied $165,000, ending WIP $62,000. What is the cost of goods manufactured for the period?
    Answer: $623,000 Cost of goods manufactured = Beginning WIP + Direct materials + Direct labor + Overhead applied - Ending WIP = $45,000 + $280,000 + $195,000 + $165,000 - $62,000 = $623,000. Option B omits the deduction for ending WIP. Option C omits beginning WIP from the calculation. Option D applies an incorrect ending WIP balance.
  7. Pinecrest Manufacturing has budgeted manufacturing overhead of $360,000 and budgeted direct labor hours of 24,000 for the year. What is the predetermined overhead rate?
    Answer: $15.00 per DLH Predetermined overhead rate = Budgeted overhead / Budgeted activity = $360,000 / 24,000 = $15.00 per DLH. Option A divides by 15,000 hours. Option B divides by 20,000 hours. Option D divides by 30,000 hours.
  8. Pinecrest Manufacturing uses job-order costing with a predetermined overhead rate of $15 per direct labor hour. Job #312 incurred direct materials of $4,200, direct labor of 180 hours at $20 per hour, and used 180 direct labor hours for overhead application. What is the total cost of Job #312?
    Answer: $10,500 Direct labor cost = 180 hours x $20 = $3,600. Applied overhead = 180 hours x $15 = $2,700. Total job cost = $4,200 + $3,600 + $2,700 = $10,500. Option A omits applied overhead entirely. Option C applies only part of the overhead. Option D applies an overhead rate higher than the predetermined rate.
  9. A manufacturer uses process costing (FIFO method). Beginning WIP: 2,000 units, 40% complete for conversion. Units started: 21,000. Units completed: 20,000. Ending WIP: 3,000 units, 60% complete for conversion. What are equivalent units of production for conversion costs under FIFO?
    Answer: 21,000 equivalent units FIFO EUP = (Beginning WIP x % remaining) + (Units started and completed) + (Ending WIP x % complete). Units started and completed = 20,000 - 2,000 = 18,000. EUP = (2,000 x 60%) + 18,000 + (3,000 x 60%) = 1,200 + 18,000 + 1,800 = 21,000. Option B uses weighted-average logic by adding all completed units plus ending WIP at full percentage. Option C counts only units started and completed. Option D uses 100% for beginning WIP remaining work.
  10. A process costing company estimates ending WIP percentage of completion at exactly 50% every period regardless of actual production stage. Which concern does this practice raise?
    Answer: Using a fixed 50% estimate without regard to actual conditions will misstate equivalent units, cost per equivalent unit, and the cost assigned between completed units and ending WIP Equivalent units and the resulting cost per unit depend directly on the percentage of completion assigned to ending WIP. A fixed 50% applied regardless of actual conditions will overstate equivalent units in periods where WIP is less complete and understate them when WIP is more complete. This systematically distorts the cost split between completed units and WIP and affects the accuracy of inventory valuation and COGS. Option A has no analytical basis. Option B is incorrect; GAAP requires a reasonable estimate of actual completion, not a 50% rule. Option D is incorrect because the materiality conclusion depends on the dollar amount involved, not just the volume percentage.
  11. Riverdale Co. has a cost per equivalent unit of $18.00 for materials and $14.00 for conversion. What is the total cost assigned to the 18,000 units completed and transferred out?
    Answer: $576,000 Cost per completed unit = $18.00 + $14.00 = $32.00. Total cost transferred = 18,000 x $32.00 = $576,000. Option A applies only the conversion cost rate to all 18,000 units. Option C applies only the materials rate to all units. Option D applies an incorrectly higher combined rate.
  12. A company switches one product line from process costing to job-order costing. Which condition most justifies this change?
    Answer: The product line has shifted from standardized mass production to customized orders with significantly different resource requirements per unit The choice between costing systems should reflect the nature of the production process. When a product line transitions from homogeneous mass production to differentiated custom orders, the cost accumulation method should change accordingly - averaging costs across dissimilar jobs would distort product costs. Option A confuses profitability tracking with the basis for costing system selection. Option B incorrectly suggests job-order costing reduces administrative burden; it is typically more labor-intensive than process costing. Option C is incorrect; GAAP does not mandate a specific costing system.
  13. A job cost sheet shows: direct materials $15,000, direct labor $12,000, applied overhead $9,000 (total $36,000). The job sold for $48,000. At year-end, the company determines the entire year's $8,000 underapplied overhead is allocable to this job. What is the adjusted gross profit after the overhead correction?
    Answer: $4,000 The $8,000 underapplied overhead is added to COGS, increasing it from $36,000 to $44,000. Adjusted gross profit = $48,000 - $44,000 = $4,000. Option A is the unadjusted gross profit before the overhead correction. Option B represents the overhead adjustment alone, not the gross profit. Option D adds the overhead correction to revenue rather than subtracting it from profit.
  14. A process costing company uses the weighted-average method. Beginning WIP had 3,000 units with $18,000 of accumulated conversion costs. Current period conversion costs were $162,000. How does the weighted-average method treat these costs differently from the FIFO method?
    Answer: Under weighted-average, total conversion costs to account for are $180,000 (beginning WIP costs plus current period); FIFO uses only the $162,000 of current period costs to compute cost per equivalent unit The weighted-average method blends beginning WIP costs with current period costs. Total costs to account for = $18,000 + $162,000 = $180,000, and this combined figure is divided by weighted-average equivalent units. FIFO keeps the cost layers separate: beginning WIP costs ($18,000) are assigned to the first units completed using prior-period rates, and only current period costs ($162,000) are divided by FIFO equivalent units to compute the current period rate. This means FIFO preserves cost period purity while weighted-average smooths costs across periods. Option B reverses which method uses which amount. Option C is incorrect; FIFO uses only $162,000 for the rate calculation. Option D is incorrect; the two methods will diverge whenever beginning WIP carries a different cost per unit than current period inputs.
  15. Sunset Industries uses job-order costing. During the period: Job #201 (cost $42,000) was completed and sold; Job #202 (cost $35,000) was completed and sold; Job #203 (cost $28,000) was completed but not yet sold; Job #204 (cost $19,000) remains in process. What is cost of goods sold for the period?
    Answer: $77,000 COGS includes only jobs completed and sold: Job #201 $42,000 + Job #202 $35,000 = $77,000. Option A includes Job #203 (finished goods, not sold). Option B includes Jobs 201, 202, and 203 minus Job 204. Option D includes all four jobs regardless of completion or sale status.
  16. Riverdale Co. has total direct materials costs of $396,000. Materials are added at the start of the process, so ending WIP is 100% complete for materials. Units completed and transferred: 18,000; ending WIP: 4,000 units. What is the cost per equivalent unit for direct materials?
    Answer: $18.00 EUP for materials = 18,000 + (4,000 x 100%) = 22,000. Cost per EU for materials = $396,000 / 22,000 = $18.00. Option B divides by 24,750, overstating equivalent units. Option C divides by 19,800. Option D divides by 18,000, treating ending WIP as having zero material content.
  17. Using the FIFO process costing data: current period conversion costs $189,000 and FIFO equivalent units for conversion of 21,000. What is the cost per equivalent unit for conversion under FIFO?
    Answer: $9.00 per equivalent unit Under FIFO, cost per EU = Current period costs only / FIFO equivalent units = $189,000 / 21,000 = $9.00. FIFO excludes beginning WIP costs from the rate calculation, preserving the prior-period cost in the beginning WIP layer. Option A divides by 23,625. Option C divides by 18,900. Option D divides by 25,200.
  18. A process costing company has beginning WIP of 5,000 units (70% complete for conversion), starts 40,000 units, completes and transfers out 38,000 units, and has ending WIP of 7,000 units (30% complete for conversion). Using the weighted-average method, what are equivalent units of production for conversion costs?
    Answer: 40,100 Weighted-average EUP = Units completed + (Ending WIP x % complete) = 38,000 + (7,000 x 30%) = 38,000 + 2,100 = 40,100. Option B treats ending WIP as fully complete (38,000 + 7,000 = 45,000 and then something else). Option C counts only completed units, ignoring ending WIP. Option D applies the wrong percentage to ending WIP (38,000 + 7,000 x 50% = 41,500).
  19. A company uses job-order costing. Job #445 had a beginning balance of $8,500. During the month, direct materials of $6,200 were requisitioned, 80 direct labor hours were worked at $25 per hour, and overhead is applied at $18 per direct labor hour. What is the ending balance on Job #445's cost sheet?
    Answer: $18,140 Direct labor = 80 hours x $25 = $2,000. Applied overhead = 80 hours x $18 = $1,440. Ending balance = $8,500 + $6,200 + $2,000 + $1,440 = $18,140. Option A omits applied overhead. Option B applies an incorrect overhead rate. Option C applies overhead to the beginning balance as well as current hours.
  20. A job-order costing company applies overhead using a single plantwide rate based on direct labor hours. Department A is labor-intensive (80% of total DLH) and Department B is machine-intensive (20% of DLH, with 60,000 machine hours and $600,000 of department-specific overhead). Which concern does the plantwide rate create?
    Answer: Jobs processed primarily through Department B are likely under-costed because the DLH plantwide rate does not capture the machine-intensive overhead consumption of that department Department B's overhead ($600,000) is driven by machine activity (60,000 hours), but the plantwide DLH rate allocates overhead based on labor hours. Because Department B uses few DLH relative to its machine-heavy overhead, jobs spending significant time in Department B will receive less overhead allocation than their actual resource consumption warrants. A departmental overhead rate using machine hours for Department B would produce more accurate costs. Option A makes an absolute claim without analytical basis. Option B is an operational suggestion unrelated to the costing accuracy question. Option C reverses the direction; Department A, which uses most of the DLH, would absorb a disproportionately high share of machine-related overhead.
