Question

1) A construction company has 5 projects. The contract amount of each project is as follows: Project 1: $1,000,000 Project 2: $2,000,000 Project 3: $1,500,000 Project 4: $1,200,000 Project 5: $ 800,000 The total overhead of this company is $120,000. Determine the overhead allocated to each of the projects if the contract amount is the allocation base. (20 points)

2) The controller decides to interview key managers of the Manufacturing, Design, and Quality departments.

The results are:

54000

Details regarding the usage of cost drivers for 3 contracts are:

Department Cost driver A B C

Manufacturing Machine hours 560 450 290

Design Number of Drawing Sheet 80 70 100

Quality Number of Inspection 160 155 190

- What is the overhead cost rate for each department? (10 points)

- What is overhead costs allocated to each contract? (10 points)

Explanation / Answer

1.) Calculation of overhead costs allocated to each contract:

                    Total overhead costs of this company = $120,000

                   The contract amount from all projects = $ 1,000,000 + 2,000,000+ 1,500,000+ 1,200,000+800,000

                                                                           = $6,500,000

    Now, Overhead costs allocated to each project:

                          Project 1 = Contract from Project 1 * Total overhead costs/ Total contract amount of all projects

                                        = 1,000,000 * 120,000/6,500,000 = $18,462

                         Project 2 = 2,000,000 * 120,000/6,500,000 = $36,923

                         Project 3 = 1,500,000* 120,000/6,500,000 = $27,692

                         Project 4 = 1,200,000* 120,000/6,500,000 = $22,154

                        Project 5 = 800,000*   120,000/6,500,000 = $14,769

2.) Calculation of overhead costs rate department wise:

                   Department               Overhead cost

             Manufacturing =   overhead costs/ Total machine hours = 100000/ (560+450+290) = $76.92 per machine hr

              Design = overhead costs/ Total drawing sheets = 54,000/ (80+70+100) = $216 per drawing sheet

              Quality = overhead costs / Total inspections = 120,000/ (160+155+190) = $237.62 per Inspection

       Calculation of overhead costs allocated to each contract:

                    Contract               Manufacturing           Design                Quality              Total

                         A                           43,077               17,280                   38,020                 98,377

                                                   ( 560 * 76.92)       (80 * 216)           (237.62 * 160)

                        B                            34,615                 15,120                  36832                 86,657

                                                   ( 450 * 76.92)       (70 * 216)           (237.62 * 155)

                        C                            22,308                  21,600                 45,148                   89,056

                                                   ( 290 * 76.92)         (100 * 216)         ( 237.62 * 190)  

                                                    100,000                   54,000             120,000
