The above procedure results in high overhead costs for labor intensive jobs with high direct labor-hour content and low overhead costs for capital intensive jobs with low direct labor-hour content.

The above procedure results in high overhead costs for capital intensive jobs which require heavy machine processing and low overhead costs for labor intensive jobs which require low machine processing.
Production OverheadAbsorption Base Machine-Hours
5
Blanket Overhead Rate• Direct labor or machine-hours has often used as
the absorption base for calculating the blanket predetermined overhead rate.
• Such absorption bases used are based on time spent in production cost centres (the higher the output, the higher the labor-hours/machine-hours, the higher the overhead applied).
• They fail to reflect many overhead cost items are not driven by the time spent in production cost centres ( i.e. product design, product planning, processing production orders, supervisor’s salary).

Activity-Based Costing (“ABC”)
7
Activity-based costing is an attempt to more accurately assign manufacturing overhead costs to products based on the activities required to products and the resources consumed by those activities.
Activity-Based Costing (“ABC”)
ABC is based on the principle that:
Products cause Activities; Activities cause Costs

Activity-Based Costing (“ABC”)
In practical terms, an ABC costing system consists of five steps:
1) Identify activities involved in the manufacture of the product
2) Calculate the total cost of each activity (the ‘cost pool’)
3) Determine what causes each activity (the ‘cost driver’)
4) Calculate the average cost per driver (the ‘cost driver rate’)
5) Assign costs to products on the use made of the activity (applying the ‘cost driver rate’).

Two products, X and Y, are made using similar equipment and methods. The data for an accounting period is as follows:
X Y
Units produced 6,000 8,000
Machine hours per unit 4 2
Production set-ups 15 45
Orders handled 12 60
The production overheads for the period can be analysed as follows:
£
Production set-ups 179,000
Order handling 30,000
Machine running costs 55,000
264,000
Seminar Question 1

1) Calculate the overheads to be absorbed by each product using a traditional machine hour rate:

Total Absorption Costing (or Absorption Costing) is referring a costing method in which all manufacturing costs are absorbed or included into a finished unit of product.

Absorption Costing vs. Marginal Costing
Cost Object
(Job)
Marginal Costing is referring a costing method in which only variable costs are included into a finished unit of product.
Under marginal costing, fixed production overheads are considered to be period costs and treated as expenses for the period.

The characteristics of businesses using the three methods are as follows:
Total absorption: Low production overheads compared with direct costs; fairly limited product range; used extensively in smaller businesses where there is some variation to the main product line e.g. printing
Marginal costing: Direct costs a high proportion of the production cost; used by businesses involved in fast moving consumer goods (fmcg) where pricing decisions are critical e.g. food industry
ABC: High production overheads; diverse product range; products using very different amounts of overheads e.g. medical equipment manufacturers

Process and Job-Order Costing
ProcessCosting
Job-OrderCosting
• Many different products are produced each period. • Products are manufactured to order.• Cost are traced or allocated to jobs.• Cost records must be maintained for each distinct
product or job.

Process and Job-Order Costing
• Produces many units of a single product for long periods.
• Products are homogeneous.• Cost are accumulated in a process unit and then
evenly allocated to each product.• Products flow through the production process on a
continuous basis.

SALES MARGIN
&
MARK-UP COSTING
29
SALES MARGIN
The product is priced to achieve a standard margin based on the SELLING PRICE
For example:Cost £1.60
Sales margin required 20%Selling price = £1.60 x 100 = £2.00
80to get back to cost = £2.00 x 80% = £1.60
30
COST PLUS (MARK-UP)
Where the product is priced to achieve a standard mark-up on COST
For example:Cost £1.20
Mark-up required 25%Selling price = £1.20 x 125 = £1.50
100to get back to cost = £1.50 x 100/125 =
£1.20
31
PREFERRED METHOD?
As a general rule:
Sales margin method is used by manufacturers
Cost plus method is used by retailers
32
What costs are covered?

SEMINAR QUESTION 2
(a) Calculate the total unit cost. (b) Calculate the selling price to the cycle shop if the company
wishes to achieve a sales margin of 10%
(c) On the basis of the answer arrived at in (b), calculate the retail price to the general public if the cycle shop’s policy is to mark-up 25% on cost to cover overheads and profit.
The unit production cost of a Crusader Mountain Bike is £232 and the company has budgeted £400,000 for selling, distribution and
administration costs, based on annual sales of 40,000 cycles per year.
34
SEMINAR QUESTION 3 Try the following……….
If sales are £280 and the sales margin is 30%, calculate the cost of sales:
If sales are £390 and the mark-up is 30%, calculate the cost of sales:
