Costing Approaches

• Actual Costing – allocates:– Indirect costs based on the actual indirect-cost rates

times the actual activity consumption• Normal Costing – allocates:

– Indirect costs based on the budgeted indirect-cost rates times the actual activity consumption

• Both methods allocate Direct costs to a cost object the same way: by using actual direct-cost rates times actual consumption

During the quarter ended 31 March, a company purchased 200 litres of liquid on the following dates:

1 February: 100 litres at RM1 per litre

1 March: 100 litres at RM2 per litre

On 30 March, 100 litres were issued to Job X. The liquid had been placed in a tank, and it would be impossible to determine which consignment had been used.

The liquid is suitable for resale in its purchased state at RM4 per litre. Assume no labour or overhead costs and opening stock.

Question: How to determine the value of closing stock ?

FIFO = RM200

LIFO = RM100

Average cost = RM150

• The most acceptable method of pricing stores issues for decision-making (Management Accounting) is replacement cost.

• Because it takes into consideration future costs.

Employee Time Ticket

Methods of Remuneration:

• Time related method

• Output related method

Accounting for Labour

Problems of Output Related Method:

• Quantity recorded on the job sheet is potentially open to abuse unless there is adequate supervision.

• Quality of the output may not be maintained as there is a temptation to produce more units in order to get higher pay.

Piece Rate (Output) with Guaranteed Pay:• This provides a security for the employees if they are

unable to achieve certain levels of output as a guaranteed minimum wage will be paid.

Differential Piecework:• In order to overcome the problem of employees slowing

down their work on reaching a certain level of earnings, an increased piece rate is offered at different level of production.

Premium Bonus Scheme

• It is a reward to the employees for any time saved on the production based on the standard time set.

• Employees will still receive normal pay in respect of the basic hours worked and the bonus is only applied to the time actually saved.

Halsey Scheme

• Time saved may be shared between employer and employees on an agreed basis.

• Formulae:

The employee receives 50% of the time saved.

Bonus = Time allowed – Time taken x Time Rate

2

Rowan Scheme

• Time saved is split on the ratio of time taken to time allowed.

• Formulae:

The proportion paid to the employee is based on the ratio of time taken to time allowed.

Bonus = Time taken x Time rate x Time saved

Time allowed

Group Bonus Scheme

• A reward to a group of employees where the bonus will be shared among the members of the group based on the pre-agreed basis.

• Advantages:• ‘Group loyalty’ may result in less absenteeism and

lateness.

Why Use an Allocation Base?

direct labor hours, direct labor dollars, or direct labor hours, direct labor dollars, or machine hours, is used to assign machine hours, is used to assign

manufacturing overhead to individual jobs.manufacturing overhead to individual jobs.

We use an allocation base because:

1. It is impossible or difficult to trace overhead costs to particular jobs.

2. Manufacturing overhead consists of many different items ranging from the grease used in machines to production manager’s salary.

3. Many types of manufacturing overhead costs are fixed even though output fluctuates during the period.

The predetermined overhead rate (POHR) used to apply overhead to jobs is determined before the period begins.

Defining Under- and Overapplied Overhead

The difference between the overhead cost applied to Work in Process and the actual overhead costs of a period is termed either underapplied or overapplied

overhead.

Underapplied overhead exists when the amount of overhead applied to jobs

during the period using the predetermined overhead rate is less than the total

amount of overhead actually incurred during the period.

Underapplied overhead exists when the amount of overhead applied to jobs

during the period using the predetermined overhead rate is less than the total

Specific orders - contract costing

• Contract costing is ‘a method of costing for specific orders in which costs are attributed to individual long-term contracts’ (Collis and Hussey, 2007, p. 262)

• Mainly used by businesses in the following sectors– Construction (eg large housing projects, office block and other

commercial/industrial premises)

– Civil engineering (eg roads, tunnels, bridges and dams)

Output Costing

Service / function Costing

Exercise 1

In a particular period, for the whole production process at Factory W, a total of 15,000 direct machine hours and 12,000 direct labour hours were used with total budgeted overhead amounted to RM120,000. Production involves a very machine intensive process. In order to complete Job X at Factory W, direct materials required is RM60 per unit. Direct labour rate per hour is RM30. Job X required 10 machine hours and 4 direct labour hours. Required: Calculate the cost of Job X.

Exercise 2

With reference to Exercise 1, if the production

process is labour intensive instead, what is the

new cost of Job X ?
