Question 1

Sunrise Products' ABC analysis determines that Product X consumes $360,000 of the $480,000 total overhead. Product X production is 2,000 units. What is the ABC overhead cost per unit for Product X?

  1. $240 per unit
  2. $120 per unit
  3. $200 per unit
  4. $180 per unit (correct answer)

Explanation: ABC overhead per unit for Product X = $360,000 / 2,000 units = 180perunit.OptionAisthetraditionalcostingoverheadperunitforProductX(180 per unit. Option A is the traditional costing overhead per unit for Product X (80 x 3 DLH). Option B is the ABC overhead per unit for Product Y ($120,000 / 1,000 = $120). Option C applies an incorrect denominator.

Question 2

Clearwater Manufacturing's ABC rates are: machine setups $300 per setup, quality inspections $300 per inspection, materials handling $300 per move. Product Alpha requires 5 setups, 8 inspections, and 4 material moves. Direct materials cost $1,200 and direct labor costs $800. What is the total ABC manufacturing cost for one batch of Product Alpha?

  1. $7,100 (correct answer)
  2. $5,100
  3. $3,900
  4. $8,300

Explanation: ABC overhead = (5 x $300) + (8 x $300) + (4 x $300) = $1,500 + $2,400 + $1,200 = $5,100. Total cost = Direct materials + Direct labor + Overhead = $1,200 + $800 + $5,100 = $7,100. Option B reports only the overhead component without adding direct materials and labor. Option C omits some overhead pools from the calculation. Option D applies incorrect driver quantities.

Question 3

Ridgemont Co. uses ABC with two pools: machine setups (360,000total,600setups)andengineeringsupport(360,000 total, 600 setups) and engineering support (180,000 total, 600 engineering hours). The Standard product uses 200 setups and 400 engineering hours. What is the total ABC overhead allocated to the Standard product?

  1. $360,000
  2. $300,000
  3. $240,000 (correct answer)
  4. $180,000

Explanation: Setup rate = $360,000 / 600 = $600 per setup. Engineering rate = $180,000 / 600 = $300 per hour. Standard overhead = (200 x $600) + (400 x $300) = $120,000 + $120,000 = $240,000. Option A is the full setup pool cost, not Standard's share. Option B is the overhead allocated to the Deluxe product. Option D is the full engineering pool cost.

Question 4

Ridgemont Co. produces 1,000 units of Standard (ABC overhead $240,000) and 500 units of Deluxe (ABC overhead $300,000). What is the ABC overhead cost per unit for each product?

  1. Standard $240 per unit; Deluxe $600 per unit (correct answer)
  2. Standard $300 per unit; Deluxe $360 per unit
  3. Standard $480 per unit; Deluxe $360 per unit
  4. Standard $200 per unit; Deluxe $500 per unit

Explanation: Standard overhead per unit = $240,000 / 1,000 = $240. Deluxe overhead per unit = $300,000 / 500 = $600. Option B divides total overhead equally across units regardless of product. Option C reverses the division logic for Standard. Option D uses incorrect denominator amounts.

Question 5

A company has an order processing cost pool of $280,000 and expects 4,000 customer orders for the period. Customer A places 15 orders during the year. What is the total order processing cost assigned to Customer A under ABC?

  1. $700
  2. $1,050 (correct answer)
  3. $1,400
  4. $875

Explanation: Cost driver rate = $280,000 / 4,000 orders = $70 per order. Customer A cost = 15 orders x $70 = $1,050. Option A applies the rate to 10 orders rather than 15. Option C applies the rate to 20 orders. Option D applies the rate to 12.5 orders using an incorrect order count.

Question 6

A manufacturer uses ABC with three pools: machine maintenance (180,000,9,000machinehours),productdesign(180,000, 9,000 machine hours), product design (120,000, 400 design changes), and packaging ($60,000, 500 shipments). Product Omega uses 600 machine hours, 20 design changes, and 30 shipments. What is the total ABC overhead assigned to Product Omega?

  1. $18,000
  2. $24,000
  3. $21,600 (correct answer)
  4. $15,600

Explanation: Rates: Maintenance = $180,000 / 9,000 = $20 per machine hour; Design = $120,000 / 400 = $300 per change; Packaging = $60,000 / 500 = $120 per shipment. Product Omega overhead = (600 x $20) + (20 x $300) + (30 x $120) = $12,000 + $6,000 + $3,600 = $21,600. Option A uses only the maintenance pool. Option B applies incorrect rates to the driver quantities. Option D omits the design cost pool from the calculation.

Question 7

Using the same firm's ABC rates (client intake $150, case management $300 per hour, admin support $150 per hour), Client B required 1 intake event, 6 case hours, and 15 admin hours. What is the total ABC cost assigned to Client B?

  1. $4,200 (correct answer)
  2. $3,600
  3. $5,100
  4. $2,400

Explanation: Client B cost = (1 x $150) + (6 x $300) + (15 x $150) = $150 + $1,800 + $2,250 = $4,200. Option B omits the intake cost and applies only case management and admin. Option C applies an incorrect case hour rate. Option D omits the admin support component entirely.

Question 8

Sunrise Products' traditional costing assigns $240 per unit to Product X and $120 per unit to Product Y. ABC analysis produces $180 per unit for Product X and $160 per unit for Product Y. Which conclusion is best supported by this comparison?

  1. Traditional costing is more accurate because it assigns higher cost to Product X, a more complex product
  2. Traditional costing over-costs Product X and under-costs Product Y, a pattern consistent with a high-volume product subsidizing a low-volume, higher-overhead-consuming product (correct answer)
  3. ABC always produces lower overhead costs than traditional allocation for all products
  4. The ABC result is incorrect because Product X should carry more overhead per unit than Product Y under any valid costing system

Explanation: Under traditional direct-labor-hour allocation, Product X (3 DLH) absorbs more overhead per unit than Product Y (1.5 DLH) simply because of labor hour consumption. ABC reveals that Product X actually consumes less overhead per unit (180)thanthetraditionalrateimplies(180) than the traditional rate implies (240) - traditional over-costs X. Conversely, Product Y is significantly under-costed under traditional costing ($120 traditional vs. $160 ABC) - its complex batch and product-level activity consumption is not captured by a labor-hour driver. This classic pattern occurs when a volume-based driver over-allocates to high-labor-intensity products and under-allocates to products that drive disproportionate batch and product-level activity. Option A accepts inaccuracy as accuracy. Option C is incorrect; ABC produces higher costs for some products and lower for others depending on actual activity consumption. Option D assumes a fixed ordering that ABC specifically aims to challenge.

Question 9

An ABC analysis reveals that a particular product consumes a disproportionately large share of batch-level and product-sustaining overhead relative to its revenue contribution. Which response is most appropriate?

  1. Eliminate the product immediately because it consumes more overhead than the company average
  2. Revert to traditional costing because ABC reveals too many cost distortions
  3. Investigate whether the product's selling price adequately covers its true resource consumption before making a retention or repricing decision (correct answer)
  4. Reduce the batch-level cost pool by consolidating product lines to lower the overhead rate

Explanation: When ABC reveals that a product consumes disproportionate overhead, the analytically correct response is to determine whether the product's price compensates for its full cost of resources consumed. The product may be viable at a higher price or may warrant discontinuation if repricing is not feasible. Option A jumps to discontinuation without evaluating profitability at the correct cost basis. Option B treats the information as a problem rather than a management tool. Option D reduces the cost pool mechanically without addressing the underlying resource consumption issue.

Question 10

A hospital implements ABC and discovers that the cardiac care service line consumes 18% of overhead activity but had been allocated 35% under the prior square-footage-based system. Which interpretation is most appropriate?

  1. Cardiac care should be expanded because it is the highest-revenue service line
  2. Cardiac care was over-charged under the prior system; ABC reveals its true overhead consumption is substantially lower, which will increase its reported profitability (correct answer)
  3. The ABC result confirms that cardiac care is unprofitable and should be restructured
  4. The prior square-footage allocation was more accurate because it used a tangible, measurable driver

Explanation: The ABC analysis shows that cardiac care was bearing 35% of overhead but actually consuming only 18%. This over-allocation under the prior system artificially depressed cardiac care's reported profitability. Under ABC, overhead allocated to cardiac care drops by nearly half, improving its reported margin. Option A conflates revenue size with the insight that ABC provides. Option C reaches the opposite conclusion from what the data shows. Option D confuses physical measurability with causal accuracy; square footage has no causal relationship with the activities that actually drive overhead in a hospital.

Question 11

A company switches from traditional to ABC overhead allocation. Total overhead remains $600,000. Under traditional costing, Product M is unprofitable and Product N is highly profitable. Under ABC, Product M becomes profitable and Product N becomes unprofitable. Which statement best explains this reversal?

  1. ABC allocates more total overhead than traditional costing, inflating Product N's costs
  2. Traditional costing was more accurate for Product N and ABC should be recalibrated
  3. Under traditional costing, Product N was likely receiving a cost subsidy from Product M through an activity-unrelated volume driver; ABC corrects this by tracing costs to actual activity consumption (correct answer)
  4. The reversal indicates ABC is unreliable because it produces results inconsistent with the prior method

Explanation: This reversal is a classic sign of cross-subsidization under traditional costing. Product N was allocated disproportionately low overhead under the volume-based driver - likely because it uses fewer direct labor hours or machine hours despite driving significant batch and product-level activities. Product M, on the other hand, was over-burdened with overhead it did not actually cause. ABC corrects the allocation by tracing costs to actual activity drivers, revealing Product M's true profitability and Product N's true cost burden. Option A is incorrect; total overhead is the same under both methods. Option B assumes traditional costing is the standard rather than recognizing its known systematic biases. Option D treats inconsistency as a defect rather than recognizing it as the purpose of the ABC analysis.

Question 12

Ridgemont Co.'s ABC rates are $600 per setup and $300 per engineering hour. The Deluxe product uses 400 setups and 200 engineering hours. What is the total ABC overhead allocated to the Deluxe product?

  1. $240,000
  2. $180,000
  3. $360,000
  4. $300,000 (correct answer)

Explanation: Deluxe overhead = (400 setups x $600) + (200 engineering hours x $300) = $240,000 + $60,000 = $300,000. Option A applies the Standard product's allocation, not Deluxe's. Option B is the full engineering pool, not Deluxe's allocation. Option C is the full setup pool cost.

Question 13

A company's ABC analysis assigns $85 per unit of overhead to a standard product and $420 per unit to a specialty product. The specialty product sells at a 30% price premium over the standard product. Which conclusion is most analytically appropriate?

  1. The specialty product should be discontinued because it carries substantially higher ABC overhead
  2. The standard product is more strategically valuable because its ABC cost is lower
  3. A 30% price premium is always sufficient to offset a higher overhead cost per unit
  4. Whether the 30% price premium adequately covers the much higher overhead per unit depends on the full cost structure and resulting contribution margin of each product (correct answer)

Explanation: The specialty product's overhead is nearly five times higher per unit. Whether a 30% revenue premium compensates for this depends on the direct cost structure, the contribution margins, and volumes of each product. If the specialty product has substantially higher direct costs as well, the premium may be insufficient. Conversely, if direct costs are similar, the pricing might be adequate. Profitability analysis requires comparing full costs and revenues, not just overhead components. Options A and B reach conclusions from a single cost dimension without full information. Option C is incorrect; a fixed price premium cannot be evaluated against a cost differential without knowing the actual margins.

Question 14

A professional services firm uses ABC with three pools: client intake (45,000,300newclients),casemanagement(45,000, 300 new clients), case management (210,000, 700 case hours), and administrative support ($75,000, 500 admin hours). Client A required 1 intake event, 12 case hours, and 8 admin hours. What is the total ABC cost assigned to Client A?

  1. $3,750
  2. $5,400
  3. $4,200
  4. $4,950 (correct answer)

Explanation: Rates: Intake = $45,000 / 300 = $150; Case management = $210,000 / 700 = $300 per hour; Admin = $75,000 / 500 = $150 per hour. Client A cost = (1 x $150) + (12 x $300) + (8 x $150) = $150 + $3,600 + $1,200 = $4,950. Option A omits the case management component. Option B applies incorrect rates across all pools. Option C is the total for Client B (see next question), not Client A.

Question 15

A company allocates $900,000 of overhead using direct labor hours. Product P is high-volume and simple; Product Q is low-volume, complex, and requires many setups and inspections. Under traditional costing, Product P shows an 8% profit margin and Product Q shows a 22% margin. Which outcome is most likely after implementing ABC?

  1. Both products' margins would increase because ABC identifies cost reduction opportunities
  2. Both products' margins would decrease because ABC allocates additional overhead to all products
  3. Both products' margins would remain unchanged because total overhead is the same under both methods
  4. Product P's margin would increase and Product Q's margin would decrease as ABC more accurately traces batch and product-level costs to each product (correct answer)

Explanation: Under traditional direct-labor-hour allocation, high-volume Product P absorbs a large share of overhead simply because it uses many total labor hours. ABC reveals that P's actual batch and product-level overhead consumption is proportionally lower than its labor hours suggest, raising its margin. Conversely, low-volume Product Q's complex profile drives disproportionate setups and inspections that ABC assigns back to it, reducing its margin. Options A and B mischaracterize how ABC redistributes existing overhead. Option C is technically true about total overhead but ignores the redistribution between products.

Question 16

Sunrise Products' ABC analysis assigns $120,000 of overhead to Product Y, which has 4,000 units of production. What is the ABC overhead cost per unit for Product Y?

  1. $30 per unit (correct answer)
  2. $120 per unit
  3. $60 per unit
  4. $45 per unit

Explanation: ABC overhead per unit for Product Y = $120,000 / 4,000 units = 30perunit.ThisissignificantlylowerthanProductY′straditionaloverheadperunit(30 per unit. This is significantly lower than Product Y's traditional overhead per unit (80 x 1.5 DLH = $120), indicating Product Y was over-costed under traditional allocation. Option B confuses the pool amount with a per-unit rate. Option C uses 2,000 units as the denominator. Option D uses an incorrect denominator.

Question 17

Clearwater Manufacturing has a machine setup cost pool of $240,000 with 800 expected setups during the period. What is the ABC cost driver rate for machine setups?

  1. $200 per setup
  2. $300 per setup (correct answer)
  3. $480 per setup
  4. $150 per setup

Explanation: Cost driver rate = Total pool cost / Total cost driver units = $240,000 / 800 setups = $300 per setup. Option A uses an incorrect denominator of 1,200. Option C divides the pool cost by 500 setups instead of 800. Option D divides by 1,600, doubling the actual driver quantity.

Question 18

Clearwater Manufacturing has a quality inspection cost pool of $150,000 with 500 expected inspections. What is the ABC cost driver rate for quality inspections?

  1. $500 per inspection
  2. $150 per inspection
  3. $300 per inspection (correct answer)
  4. $750 per inspection

Explanation: Cost driver rate = $150,000 / 500 inspections = $300 per inspection. Option A divides the pool cost by 300 instead of 500. Option B divides by 1,000, which doubles the driver quantity. Option D divides by 200, significantly understating the driver base.

Question 19

In activity-based costing, a batch-level activity is best described as which of the following?

  1. An activity performed once for each individual unit produced or sold
  2. An activity performed once per production run, with the cost independent of the number of units in the batch (correct answer)
  3. An activity performed to support the continued existence of a specific product line in the product portfolio
  4. An activity performed to sustain the overall production facility regardless of which specific products are manufactured

Explanation: A batch-level activity occurs each time a batch or production run is processed, and its total cost depends on the number of batches, not the number of units within each batch. Machine setups, purchase orders, and first-article inspections are classic batch-level activities. Option A describes a unit-level activity. Option C describes a product-sustaining activity. Option D describes a facility-sustaining activity.

Question 20

Sunrise Products has total manufacturing overhead of $480,000 and budgeted direct labor hours of 6,000. What is the predetermined overhead rate under traditional costing?

  1. $60 per DLH
  2. $80 per DLH (correct answer)
  3. $100 per DLH
  4. $48 per DLH

Explanation: Predetermined overhead rate = Total overhead / Total cost driver = $480,000 / 6,000 DLH = $80 per DLH. Option A divides by 8,000 DLH. Option C divides by 4,800 DLH. Option D divides by 10,000 DLH.
