Why is JIT costing sometimes called backflush costing?

Short Answer

Expert verified

JIT is called backflush costing as it seems to work backward by assigning manufacturing costs to units sold and inventories when the output is completed.

Step by step solution

01

JIT costing

Just-in-time costing is a costing system that determines the cost of units after the completion of the production process. Under this system, a temporary account called “conversion” account and an inventory account named – “Raw and In-Process Inventory” account are prepared to determine the cost of finished units.

02

JIT costing as backflush costing

JIT costing is called backflush costing as the cost of finished units are determined at the end of the production process. Backflush is used to denote the backward working of JIT costing.

Under JIT costing the conversion cost and raw material cost are allocated to the finished product when the production is gets completed. The under or over-allocated conversion cost is transferred to the cost of goods sold account at the end of the period.

In this way, this system works backward.

What is a just-in-time management system?

Question:The Santos Shirt Company manufactures shirts in two departments: Cutting and Sewing. The company allocates manufacturing overhead using a single plantwide rate with direct labor hours as the allocation base. Estimated overhead costs for the year are\(500,000, and estimated direct labor hours are 200,000. In June, the company incurred 17,500 direct labor hours.

1. Compute the predetermined overhead allocation rate.

2. Determine the amount of overhead allocated in June.

The Santos Shirt Company has refined its allocation system by separating manufacturing overhead costs into two cost pools—one for each department. The estimated costs for the Cutting Department are \)200,000. They will be allocated based on directlabor hours, which are estimated to be 125,000 hours for the year. The estimated costs for the Sewing Department are $300,000.Those costs will be allocated based on machine hours, which are estimated to be 150,000 hours for the year. In June, the companyincurred 10,000 direct labor hours in Cutting and 12,500 machine hours in Sewing.

3. Compute the predetermined overhead allocation rates for each department.

4. Determine the total amount of overhead allocated in June.

Koehler (see Exercise E19-15) makes handheld calculators in two models—basic and professional—and wants to refine its costing system by allocating overhead using departmental rates. The estimated \(721,000 of manufacturing overhead has been divided into two cost pools: Assembly Department and Packaging Department. The following data have been compiled:

Assembly Packaging

Department Department Total

Overhead costs \) 456,500 \( 264,500 \) 721,000

Machine hours:

Basic Model 185,000 MHr 45,000 MHr 230,000 MHr

Professional Model 230,000 MHr 55,000 MHr 285,000 MHr

Total 415,000 MH 100,000 MHr 515,000 MHr

Direct labor hours:

Basic Model 20,000 DLHr 50,000 DLHr 70,000 DLHr

Professional Model 105,125 DLHr 280,625 DLHr 385,750 DLHr

Total 125,125 DLHr 330,625 DLHr 455,750 DLHr

Compute the predetermined overhead allocation rates using machine hours as the allocation base for the Assembly Department and direct labor hours for the Packaging Department. How much overhead is allocated to the basic model? To the professional model? Round allocation rates to two decimal places and allocated costs to whole dollars.

Explain how the work cell manufacturing layout increases productivity.

Harris Systems specializes in servers for workgroup, e-commerce, and ERP applications. The company’s original job costing system has two direct cost categories: direct materials and direct labor. Overhead is allocated to jobs at the single rate of \(22 per direct labor hour.

A task force headed by Harris’s CFO recently designed an ABC system with four activities. The ABC system retains the current system’s two direct cost categories. Overhead costs are reflected in the four activities. Pertinent data follow:

___________________________________________________________________

Activity Allocation Base Predetermined Overhead

Allocation Rate____

Materials handling Number of parts \) 0.85

Machine setup Number of setups 500.00

Assembling Number of assembling hours 80.00

Shipping Number of shipments 1,500.00_______

Harris Systems has been awarded two new contracts, which will be produced as Job A and Job B. Budget data relating to the contracts follow:

____________________________________________________________

Job A Job B__

Number of parts 15,000 2,000

Number of setups 6 4

Number of assembling hours 1,500 200

Number of shipments 1 1

Total direct labor hours 8,000 600

Number of units produced 100 10

Direct materials cost \( 220,000 \) 30,000

Direct labor cost \( 160,000 \) 12,000__

Requirements

1. Compute the budgeted product cost per unit for each job, using the original costing system (with two direct cost categories and a single overhead allocation rate).
