4.7 Athena Ltd is an engineering business doing work for its customers to their particular requirements and specifications. It determines the full cost of each job taking a ‘job-costing’

approach, accounting for overheads on a cost centre (departmental) basis. It bases its prices to customers on this full cost figure. The business has two departments (both of which are cost centres): a Machining Department, where each job starts, and a Fitting Department, which completes all of the jobs. Machining Department overheads are charged to jobs on a machine hour basis and those of the Fitting Department on a direct labour hour basis.

The budgeted information for next year is as follows:

Heating and lighting £25,000 (allocated equally between the two departments)

Machine power £10,000 (all allocated to the Machining Department)

Direct labour £200,000 (£150,000 allocated to the Fitting Department and £50,000 to the Machining Department; all direct workers are paid £10 an hour)

Indirect labour £50,000 (apportioned to the departments in proportion to the direct labour cost)

Direct materials £120,000 (all applied to jobs in the Machining Department)

Depreciation £30,000 (all relates to the Machining Department)

Machine time 20,000 hours (all worked in the Machining Department)

Required:

(a) Prepare a statement showing the budgeted overheads for next year, analysed between the two cost centres. This should be in the form of three columns: one for the total figure for each type of overhead and one column each for the two cost centres, where each type of overhead is analysed between the two cost centres. Each column should also show the total of overheads for the year.

(b) Derive the appropriate rate for charging the overheads of each cost centre to jobs

(that is, a separate rate for each cost centre).

(c) Athena Ltd has been asked by a customer to specify the price that it will charge for a particular job that will, if the job goes ahead, be undertaken early next year. The job is expected to use direct materials costing Athena Ltd £1,200, to need 50 hours of machining time, 10 hours of Machine Department direct labour and 20 hours of Fitting Department direct labour. Athena Ltd charges a profit loading of 20 per cent to the full cost of jobs to determine the selling price.

Show workings to derive the proposed selling price for this job.
