Hull Test Laboratories does heat testing (HT) and stress testing (ST) on materials and operates at capacity. Under its current simple costing system, Hull aggregates all operating costs of $1,120,000 into a single overhead cost pool. Hull calculates a rate per test-hour of $14 ($1,120,000/ 80,000 total test-hours). HT uses 54,000 test-hours, and ST uses 26,000 test-hours. Gary Lawler, Hull's controller, believes that there is enough variation in test procedures and cost structures to establish separate costing and billing rates for HT and ST. The market for test services is becoming competitive. Without this information, any miscosting and mispricing of its services could cause Hull to lose business. Lawler divides Hull's costs into four activity-cost categories. (Click the icon to view the activity-cost categories.) Read the requirements. a. Direct labor Cost Item b. Equipment-related costs (rent, maintenance, energy, etc.) c. Setup costs d. Costs of designing tests Cost-type Output unit-level Output unit-level Batch-level Service-sustaining Output unit-level costs are related to the number of units tested; required for each unit tested. Batch-level costs are related to a group of units of the service. They are not related to the number of units tested. Service-sustaining costs are costs used to support individual services regardless of the number of units or batches tested. Facility-sustaining costs are costs that can not be traced to individual services but support the company as a whole. Requirement 2. Calculate the cost per test-hour for HT and ST. Explain briefly the reasons why these numbers differ from the $14 per test-hour that Hull calculated using its simple costing system. First, determine the formula used to calculate the cost for each activity in each test type. Activity rate Cost per activity Activity hours per test type = Calculate the cost of each activity and the total cost of the heat testing and stress testing. i Data Table - a. Direct-labor costs, $294,500. These costs can be directly traced to HT, $229,500, and ST, $65,000. b. Equipment-related costs (rent, maintenance, energy, and so on), $320,000. These costs are allocated to HT and ST on the basis of test-hours. c. Setup costs, $360,000. These costs are allocated to HT and ST on the basis of the number of setup-hours required. HT requires 14,600 setup-hours, and ST requires 3,400 setup-hours. d. Costs of designing tests, $280,000. These costs are allocated to HT and ST on the basis of the time required to design the tests. HT requires 2,500 hours, and ST requires 2,500 hours. Print Done Heat Test (HT) Total Cost Direct labor 229,500 Equipment Setup Design Total
