3 Estimated total manufacturing overhead cost for the coming period Estimated total units in the allocation base for the coming period POHR = The predetermined overhead rate (POHR) used to apply overhead to jobs is determined before the period begins. Application of Manufacturing Overhead Ideally, the allocation base is a cost driver that causes overhead.

4 Application of Manufacturing Overhead Overhead applied = POHR × Actual activity Actual amount of the allocation base such as units produced, direct labor hours, or machine hours incurred during the period. Based on estimates, and determined before the period begins.

5 Application of Manufacturing Overhead Recall the wooden crate example where: Overhead applied = $4 per DLH × 8 DLH = $32 Overhead applied = POHR × Actual activity

6 The Need for a Predetermined Manufacturing Overhead Rate Using a predetermined rate makes it possible to estimate total job costs sooner. Actual overhead for the period is not known until the end of the period.

7 Note If we wait until the end of the period, we will know the actual TOTAL overhead cost. However, still we won’t know the actual overhead cost of a particular job. Why? – Overhead consists of costs that are either difficult or impossible to trace to particular jobs. Difficult-to-trace costs include the cost of indirect materials like glue in a furniture factory. Impossible-to-trace costs include fixed common costs like the property taxes on the factory building and land.

8 PearCo applies overhead based on direct labor hours. Total estimated overhead for the year is $640,000. Total estimated labor cost is $1,400,000 and total estimated labor hours are 160,000. What is PearCo’s predetermined overhead rate per hour? Overhead Application Example

9 For each direct labor hour worked on a job, $4.00 of factory overhead will be applied to the job. Overhead Application Example POHR = $4.00 per DLH $640, ,000 direct labor hours (DLH) POHR = Estimated total manufacturing overhead cost for the coming period Estimated total units in the allocation base for the coming period POHR =

12 MCQs Test If the number of wooden crates in the order on the previous page is increased or decreased by one unit, what would you expect to happen to the total spending of PearCo? a. Total spending would probably change by less than $105. b. Total spending would probably change by about $105. c. Total spending would probably change by more than $105.

13 MCQs Test If the number of wooden crates in the order on the previous page is increased or decreased by one unit, what would you expect to happen to the total spending of PearCo? a. Total spending would probably change by less than $105. b. Total spending would probably change by about $105. c. Total spending would probably change by more than $105. Total spending would change by $105 only if all of the costs were variable with respect to the number of units produced. Direct materials is variable, but much of the overhead and perhaps even direct labor may be fixed.

14 MCQs Test Job WR53 at Pharmo Inc. required $200 of direct materials and 10 direct labor hours at $15 per hour. Estimated total overhead for the year was $760,000 and estimated direct labor hours were 20,000. What would be recorded as the cost of job WR53? a. $200. b. $350. c. $380. d. $730.

15 MCQs Test Job WR53 at Pharmo, Inc. required $200 of direct materials and 10 direct labor hours at $15 per hour. Estimated total overhead for the year was $760,000 and estimated direct labor hours were 20,000. What would be recorded as the cost of job WR53? a. $200. b. $350. c. $380. d. $730.

16 MCQs Test Job WR53 at Pharmo, Inc. required $200 of direct materials and 10 direct labor hours at $15 per hour. Estimated total overhead for the year was $760,000 and estimated direct labor hours were 19,000. What would be recorded as the cost of job WR53? a. $200. b. $350. c. $750. d. $730.

17 MCQs Test Job WR53 at NW Fab, Inc. required $200 of direct materials and 10 direct labor hours at $15 per hour. Estimated total overhead for the year was $760,000 and estimated direct labor hours were 19,000. What would be recorded as the cost of job WR53? a. $200. b. $350. c. $750. d. $730.

18 MCQs Test If overhead contains fixed costs, what will happen to the predetermined overhead rate if lower unit sales volume is expected? a. The predetermined overhead rate will likely increase. b. The predetermined overhead rate would be unaffected. c. The predetermined overhead rate will likely decrease.

19 MCQs Test If overhead contains fixed costs, what will happen to the predetermined overhead rate if lower unit sales volume is expected? a. The predetermined overhead rate will likely increase. b. The predetermined overhead rate would be unaffected. c. The predetermined overhead rate will likely decrease.

20 MCQs Test If overhead contains fixed costs and management set prices by marking up product costs by a preset percentage, what will happen to selling prices if lower unit sales volume is expected? a. Selling prices will likely increase. b. Selling prices would be unaffected. c. Selling prices will likely decrease.

21 MCQs Test If overhead contains fixed costs and management set prices by marking up product costs by a preset percentage, what will happen to selling prices if lower unit sales volume is expected? a. Selling prices will likely increase. b. Selling prices would be unaffected. c. Selling prices will likely decrease.

22 MCQs Test If selling prices increase, what will happen to unit sales volume? a. Unit sales volume will likely increase. b. Unit sales volume would be unaffected. c. Unit sales volume will likely decrease.
