For Predicting Cost Behavior: Variable

Cost vs Fixed Cost

Behavior of Cost (within the relevant range)

Cost In Total Per Unit

Variable Total variable cost changes Variable cost per unit remains

as activity level changes. the same over wide ranges

of activity.

Fixed Total fixed cost remains Average fixed cost per unit goes

the same even when the down as activity level goes up.

activity level changes.

Page 11: Revision for Final Exam

Slide 11

For Decision Making: Differential Cost,

Opportunity Cost and Sunk Cost

Differential cost: differ among

alternatives.

Opportunity cost: potential benefit

given up when selecting one

alternative over another.

Sunk cost: already incurred and

cannot be changed now or in the

future.

Part 02 - Chapter 3

Page 14: Revision for Final Exam

Slide 14

Types of Product Costing Systems

Process

Costing

Job-order

Costing

A company produces many units of a single product.

One unit of product is indistinguishable from other units of product.

The identical nature of each unit of product enables assigning the same average cost per unit.

Page 15: Revision for Final Exam

Slide 15

Types of Product Costing Systems

Process

Costing

Job-order

Costing

Many different products are produced each period.

Products are manufactured to order.

The unique nature of each order requires tracing or allocating costs to each job, and maintaining cost records for each job.

Page 16: Revision for Final Exam

Slide 16

Why Use an Allocation Base?

Manufacturing overhead is applied to jobs that are

in process.

Common allocation base: direct labor hours, direct

labor dollars, or machine hours.

We use an allocation base because:

1. Impossible or difficult to trace MOH to particular jobs.

2. MOH consists of many items like the grease or production

manager’s salary.

3. Many types of MOH are fixed even though output fluctuates during

the period.

Page 17: Revision for Final Exam

Slide 17

Using the Predetermined OverHead Rate (POHR):

Manufacturing Overhead Application

Estimated total MOH for the coming period

Estimated total units in the allocation base

POHR =

Applied Overhead = POHR × Actual DLHs

Page 18: Revision for Final Exam

Slide 18

Problems of MOH Application

The difference between applied MOH and actual

MOH: Underapplied or Overapplied overhead.

Underapplied OH

Applied MOH < Actual MOH

Overapplied OH

Applied MOH > Actual MOH

Slide 23

Equivalent Units of Production

Equivalent units are the product of the number of partially completed units and the percentage

completion of those units.

We need to calculate equivalent units because a

department usually has some partially completed units

in its beginning and ending inventory.

Page 24: Revision for Final Exam

Slide 24

Equivalent Units – The Basic Idea

Two half completed products are

equivalent to one complete product.

Eg: 10,000 units 70% complete

are equivalent to 7,000 complete units.

+ = 1

Page 25: Revision for Final Exam

Slide 25

Calculating Equivalent Units

Using the Weighted-Average Method

Page 26: Revision for Final Exam

Slide 26

Weighted-Average – An Example

Smith Company reported the following activity in

the Assembly Department for the month of June:

Percent Completed

Units Materials Conversion

Work in process, June 1 300 40% 20%

Units started into production in June 6,000

Units completed and transferred out 5,400

of Department A during June

Work in process, June 30 900 60% 30%

Page 27: Revision for Final Exam

Slide 27

Materials Conversion

Units completed and transferred

out of the Department in June 5,400 5,400

Work in process, June 30:

900 units × 60% 540

900 units × 30% 270

Equivalent units of Production in

the Department during June 5,940 5,670

Equivalent units of production always equals:

Units completed and transferred

+ Equivalent units remaining in work in process

Cost to be accounted for:

Work in process, June 1 10,039$ 6,119$ 3,920$

Cost added in Assembly 199,751 118,621 81,130

Total cost 209,790$ 124,740$ 85,050$

Equivalent units 5,940 5,670

Cost per equivalent unit 21.00$ 15.00$

Compute and Apply Costs

Here is a schedule with the cost and equivalent

unit information.

$124,740 ÷ 5,940 units = $21.00 $85,050 ÷ 5,670 units = $15.00

Cost per equivalent unit = $21.00 + $15.00 = $36.00

Slide 40

Cost Structure and Profit Stability

There are advantages and disadvantages to

high fixed cost and low fixed cost structures.

An advantage of a high fixed

cost structure is that income

will be higher in good years. A disadvantage of a high fixed

cost structure is that income

will be lower in bad years.

Companies with low fixed cost structures enjoy greater

stability in income across good and bad years.

Page 41: Revision for Final Exam

Slide 41

Key Assumptions of CVP Analysis

Selling price is constant.

Costs are linear and can be accurately divided

into variable and fixed elements.

In multiproduct companies, the sales mix is

constant.

In manufacturing companies, inventories do not

change (units produced = units sold).

Summary of Key Insights

Page 47: Revision for Final Exam

Slide 47

Advantages of Variable Costing and the Contribution Approach

Advantages

Management finds it more useful.

Consistent with CVP analysis.

Net operating income is closer to

net cash flow.

Profit is not affected by changes in inventories.

Consistent with standard costs and flexible budgeting.

Impact of fixed costs on profits emphasized.

Easier to estimate profitability of products and segments.

Page 48: Revision for Final Exam

Slide 48

Major criticism of Absorption Costing

Profits will depend not only on sales,

but on changes in inventories.

By increasing production and building up inventory,

profits increased without any increase in sales

or reduction in costs

Slide 65

Standard Costs

Standards are benchmarks for

measuring performance.

Two types of standards are commonly used.

Quantity standards

specify how much of an

input should be used to

make a product or

provide a service.

Price standards

specify how much

should be paid for

each unit of the

input.

Examples: Firestone, Sears, McDonald’s, hospitals,

construction and manufacturing companies.

Assume that Regal's manager invests in a $30,000 piece of equipment that increases sales by

$35,000, while increasing operating expenses by $15,000.

Let’s calculate the new ROI.

Regal Company reports the following:

Net operating income $ 50,000

Average operating assets $ 230,000

Sales $ 535,000

Operating expenses $ 485,000

Slide 92

Criticisms of ROI

In the absence of the balanced

scorecard, management may

not know how to increase ROI.

Managers often inherit many

committed costs over which

they have no control.

Managers evaluated on ROI

may reject profitable

investment opportunities.

Relevant Costs for Decision Making

Part 10 - Chapter 14

Page 95: Revision for Final Exam

Slide 95

Cost Concepts for Decision Making

A relevant cost is a cost that differs

between alternatives.

Page 96: Revision for Final Exam

Slide 96

Identifying Relevant Costs

An avoidable cost is a cost that can be eliminated,

in whole or in part, by choosing one alternative

over another. Avoidable costs are relevant costs.

Unavoidable costs are irrelevant costs.

Two broad categories of costs are never relevant

in any decision. They include:

Sunk costs.

Future costs that do not differ between the

alternatives.

Page 97: Revision for Final Exam

Slide 97

Identifying relevant costs

The Tolar Company has 400 obsolete desk

calculators that are carried in inventory at a total cost

of $26,800. If these calculators are upgraded at a

total cost of $10,000, they can be sold for a total of

$30,000. As an alternative, the calculators can be

sold in their present condition for $11,200.

Page 98: Revision for Final Exam

Slide 98

Identifying relevant costs

1. The sunk cost in this situation is:

A. $10,000

B. $26,800

C. $11,200

D. $0

Page 99: Revision for Final Exam

Slide 99

Identifying relevant costs

2. What is the net advantage or disadvantage to the

company from upgrading the calculators?

A. $8,800 advantage

B. $18,000 disadvantage

C. $20,000 advantage

D. $8,000 disadvantage

Page 100: Revision for Final Exam

Slide 100

Identifying relevant costs

3. Assume that Tolar decides to upgrade the

calculators. At what selling price per unit would the

company be as well off as if it just sold the calculators

in their present condition?

A. $8

B. $30

C. $53

D. $67

Page 101: Revision for Final Exam

Slide 101

Key Terms and Concepts

When a limited resource of

some type restricts the

company’s ability to satisfy

demand, the company is

said to have a constraint.

The machine or

process that is

limiting overall output

is called the

bottleneck – it is the

constraint.

Page 102: Revision for Final Exam

Slide 102

Utilization of a Constrained Resource

A company should not necessarily promote those

products that have the highest Unit CM.

Rather, total CM will be maximized by promoting

those products or accepting those orders that

provide the highest CM in relation to the

constrained resource.

Page 103: Revision for Final Exam

Slide 103

Utilization of a Constrained Resource: An

Example

Ensign Company produces two products and

selected data are shown below:

Product

1 2

Selling price per unit $ 60 $ 50

Less variable expenses per unit 36 35

Contribution margin per unit 24$ 15$

Current demand per week (units) 2,000 2,200

Contribution margin ratio 40% 30%

Processing time required

on machine A1 per unit 1.00 min. 0.50 min.

Page 104: Revision for Final Exam

Slide 104

Utilization of a Constrained Resource: An

Example

Machine A1 is the constrained resource and is being used at 100% of its capacity.

There is excess capacity on all other machines.

Machine A1 has a capacity of 2,400 minutes per week.

Should Ensign focus its efforts on Product 1 or Product 2?

Slide 105

Utilization of a Constrained Resource

Ensign can maximize its contribution margin

by first producing Product 2 to meet customer

demand and then using any remaining

capacity to produce Product 1. The

calculations would be performed as follows.

The key is the contribution margin per unit of the

constrained resource.

Product

1 2

Contribution margin per unit $ 24 $ 15

Time required to produce one unit ÷ 1.00 min. ÷ 0.50 min.

Contribution margin per minute 24$ 30$

Slide 106

Utilization of a Constrained Resource

Let’s see how this plan would work.

Alloting Our Constrained Resource (Machine A1)

Weekly demand for Product 2 2,200 units

Time required per unit × 0.50 min.

Total time required to make

Product 2 1,100 min.

Total time available 2,400 min.

Time used to make Product 2 1,100 min.

Time available for Product 1 1,300 min.

Time required per unit ÷ 1.00 min.Production of Product 1 1,300 units

Slide 107

Utilization of a Constrained Resource

According to the plan, we will produce 2,200

units of Product 2 and 1,300 of Product 1.

Our contribution margin looks like this.

Product 1 Product 2

Production and sales (units) 1,300 2,200

Contribution margin per unit 24$ 15$

Total contribution margin 31,200$ 33,000$

The total contribution margin for Ensign is $64,200.

Slide 108

Managing Constraints It is often possible for a manager to increase the capacity of a

bottleneck, which is called relaxing (or elevating) the constraint,

in numerous ways such as:

1. Working overtime on the bottleneck.

2. Subcontracting some of the processing that would be done

at the bottleneck.

3. Investing in additional machines at the bottleneck.

4. Shifting workers from non-bottleneck processes to the

bottleneck.

5. Focusing business process improvement efforts on the

bottleneck.

6. Reducing defective units processed through the bottleneck.

These methods and ideas are all consistent with the Theory

of Constraints.
