**Activity 1 : Profit and Rate of Return of Cake Shop **

**Step 1: **

** Unit ** **contribution =**

### =

### Unit selling price – Unit variable costs

### $10 - $6 = $4

*Unit contribution is the revenue remaining after deducting variable costs. Unit * *contribution measures the contribution made by each unit of product sold to cover the * *fixed costs and generate profit. *

**Step 2: **

**Fixed Cost per month **

### Rent = $10,000

### Wages ($8,000 x 2) = $16,000 Operating expenses = $4,000

### = $30,000

**Step 3: **

**Profit for each month ** = Sales – Variable costs – Fixed costs

### = Contribution – Fixed costs

### = Units of sales x unit contribution – Fixed costs

### = 10,000 units x $4 - $30,000

**Activity 3 :Case Study - Part III ** **1. Step 1: **

**Unit contribution ** = Unit selling price – Unit variable cost

### = $11 - $7.5 =$3.5 **Step 2: **

**Profit for each month ** = Contribution – Fixed costs

### = 10,000 units x $3.5 - $30,000

### = $5,000

**Profit for each year ** = $5,000 x 12 months = $60,000 **Rate of return per annum ** = $60,000 / $600,000 = 10%

### The fixed costs of $30,000 per month remain unchanged.

**Margin of safety ** = Sales volume – break-even volume (in units) for each month = 10,000 units – 8,571 units

### = 1,429 units

### (in %) = 1,429 units / 10,000 units

### = 14.29%

*The company has a margin of safety of 14.29%, which means the business will incur a * *loss if the sales volume is decreased by 14.29% or worse than that. As Mary says all * *are loyal customers, there is low possibility that the sales volume will drop by this * *amount and the margin is still comfortable even when the unit contribution is * *decreased. *

**3. **

*When the unit contribution is decreased by $0.5, the rate of return for this investment * *is 10% which is still a reasonable return. *

**4. **

**Recommendation **

### There is an 80% chance that the annual profit is $120,000 and the rate of return is 20%, and a 20% chance that the annual profit is $60,000 and the rate of return is 10%.

### Even in the second situation, the investment is sound as the return is reasonable and the risk is low, therefore, it is recommended that Eric acquires the business.

**Suggested answers **

**Activity 4 : Acceptance of a proposal **

**Eric mixes up variable costs with fixed costs and draws an incorrect conclusion. **

**A variable cost is a cost that varies with some measure of output or activity, whereas a ** **fixed cost is a cost that, in total, remains constant for a specified time period. The ** **fixed cost $30,000 per month will not increase even if the sales volume is ** **increased by 10,000 units. **

**Correct approach **

### The relevant cost is the variable cost which will increase as the sales volume increases.

### The correct approach is to compare the increase in contribution with the additional expenditure.

### Additional contribution = 10,000 units * $4 = $40,000

### = $40,000

### Additional expenditure = $10,000

**Incremental profit ** = Additional contribution – Additional expenditure

### = $40,000 - $10,000

### = $30,000

**Conclusion **

### As there is an increase of $30,000 in the profit, the proposal should be implemented.

### Topic A10: Cost-Volume-Profit Analysis Topic Overview P.10

### BAFS Learning & Teaching Examples As at April 2009

**Activity 5: Solving Business Problem ** **Step 1: **

**Increase in fixed cost per month ** = $10,000 * 20% = $2,000 New fixed cost per month = $30,000 + $2,000

### = $32,000

**Step 2: **

**Profit for each month ** = Contribution – Fixed costs

### = 10,000 units x $4 - $32,000

### = $8,000

**Profit for each year ** = $8,000 x 12 months = $96,000 **Rate of return per annum ** = $96,000 / $600,000 = 16%

**Step 3: **

### $32,000 **Break-even point (units) **

**for each month ** = $4

### = 8,000 units

**Margin of safety ** = Sales volume – break-even volume (in units) for each month = 10,000 units – 8,000 units

### = 2,000 units

### (in %) = 2,000 units / 10,000 units

### = 20%

**Recommendation **

*The company has a 20%, margin of safety which means the business will incur a loss if * *the sales volume is decreased by 20% or worse than that. As Mary says there are * *many loyal customers, there is a low possibility that the sales volume will drop by this * *amount and the margin is comfortable. *

*An 20% increase in fixed costs will reduce the rate of return by 4 percent to 16% *

*resulting in a safety margin by 5 percentage points to 20%. The margin of safety is * *comfortable and the return is reasonable, so Eric should continue his business under * *the new situation. *

**Profit for each year ** = $8,800 * 12 months = $105,600 **Annual rate of return ** = $105,600 / $600,000 = 17.6%

**Recommendation **

### The annual profit is $9,600 ($105,600 - $96,000) higher if the plan is implemented.

### However, the margin of safety is 3.3% lower in percent points ($20 % - $16.7%). The 16.6% margin of safety is still a comfortable margin and it is recommended that Eric implement his plan.

CVP Analysis

BAFS Elective Part Learning and Teaching Example

**CVP Analysis**

The CVP analysis is a key in decision making, including choice of product lines, pricing of products, marketing strategies and utilisation of production facilities.

The CVP analysis is sometimes referred to as a break-even analysis. A break-even analysis shows the relationship among costs, volume, contribution and profits at various levels of activity. The sales volume which equates total revenue with related costs and results in neither profit nor loss is called the break-even point (BEP).

The CVP analysis uses the principles of marginal costing and is best suited for short run issues. It explores the relationship among costs, revenue, output levels and resulting profits and is more relevant where the proposed changes in the levels of activity are relatively small.

5.Unit contribution = Unit selling price – Unit variable costs 6.Sales volume * Unit contribution = Fixed costs + Profit

7.Volume to earn a target profit = (Fixed costs + Profit) / Unit contribution 8.Break-even sales volume would results in neither a profit nor loss, i.e.

Profit = 0

**Basic Assumptions**

z

### Within a relevant volume range and in a short run

### 1. The costs can be accurately divided into variable and fixed elements.

### 2. The unit selling price and unit variable costs remain constant throughout the whole range.

### 3. Fixed costs are costs, that in total, remain constant for a specified time period.

It is important to emphasise the basic assumptions as the analysis would be meaningless if the basic assumptions are not sustained.

**Case Study**

z

### Should Eric buy the cake shop ?

z

### Activity 1 : Please help Eric to figure out the annual profit and rate of return of the cake shop.

Brief description of the case:

Your friend Eric Chan has been approached by his best friend Mary Wong, and asked whether he is interested in buying her cake shop. It is a small cake shop selling one very special cake imported from Japan.

Mary is asking for $600,000 and she says that the annual profit and the rate of return on this investment are $120,000 and 20% respectively. Eric considers that the profit and the rate of return very attractive but he is weak in accounting. He asks you to show him how the figures of profit and rate of return are arrived at.

This is a typical case in which CVP analysis can be applied. Teacher asks students to follow the steps on the next slide in answering the questions from Eric.

**Activity 1 – Profit and Rate of ** **Return of the Cake Shop**

### 1. Calculate the contribution per unit of cake.

### 2. Identify the fixed costs and calculate the total fixed costs per month.

### 3. Calculate monthly profit and annual profit.

### 4. Calculate the investment rate of return.

Students can refer to student worksheets pp.1-2 for details and divide into groups to complete the case study

Unit contribution is the revenue remaining after deducting variable costs.

Unit contribution measures the contribution made by each product unit sold to cover the fixed costs and generate business profits. Calculating unit contributions is the first step in most CVP analyses.

Usually, we use the contribution approach in calculating profit.

Refer to the footnote in slide #4 for the formulae in calculating the above figures.

**Activity I – Key Points Learned**

### 1. Profit calculation

### 2. Rate of return calculation

One important factor to be considered in making an investment is its rate of return. But before calculating the rate of return, we have to calculate the profit and the amount of investment.

Rate of return = Profit / Investment

**Break-even Point**

### At the break-even point, there is no profit nor loss.

z

### It is the point where

z

### Sales revenue = Total costs

z

### Contribution = Fixed costs

Teacher explains the concept of break-even again before proceeding to Activity 2.

Break-even point is when total revenue equals total costs incurred. It identifies activities required to cover costs but not generating any profits.

The break-even point in units is calculated by dividing total fixed costs by the contribution per unit.

**Case Study **

z

### Should Eric buy the cake shop ?

z

### Activity 2 : Please advise Eric whether he should buy the cake shop based on the rate of return and the margin of safety.

Teacher tells students that besides the rate of return, another important factor that must be considered is the investment risk.

Margin of safety tells us the “cushion” of losing sales before incurring a loss if the expected sales fails to materialise. If the Margin of safety is low, say below 10%, Eric should not buy the business as the business will incur a loss when there is a drop of sales volume by 10% or more, which is quite risky.

**Activity 2 – Breakeven Point ** **and Margin of Safety**

### 1. Calculate units of cakes to be sold per month to break even.

### 2. Calculate the margin of safety.

### 3. Recommendation.

Students stay with their groups and finish student worksheets p.2-3.

Margin of safety indicates by how much sales may decrease before a loss occurs. It represents the difference between the level of sales and the break-even point. It can be expressed in units, sales revenue and percentages. It is the “cushion” before incurring a loss if the expected sales fails to materialise.

Break-even point = Fixed costs / Unit contribution

Margin of safety = Expected sales volume – Break-even sales volume (in units)

Margin of safety = (Expected sales volume – Break-even sales volume) / Expected sales volume (in %)

z

### Acquire the business.

### 25%

### 20%

In this case, The company has a margin of safety of 25%, which means the business will incur a loss if the sales volume decrease by 25% or more.

As Mary states there are many loyal customers, there is a low possibility that the sales volume will drop by this substantial amount and the margin is comfortable.

As the risk of this investment is low and the rate of return is high, students should suggest Eric to acquire the business.

**Activity 2 – Key Points Learned**

z

### Break-even point

z

### Margin of safety as a measure of the risk of incurring a loss.

Return and risk are two important factors in making any investment decisions.

If the return is high but the corresponding risk is very high, most people will not make such an investment. Most investors would like to invest in a business of reasonable return and acceptable risk. There are many risk factors and one important factor is the decrease in sales. Margin of safety measures the risk in this aspect.

**Activity 3 – Another Situation **

There is a 20% chance that the supplier will increase the price of each cake from $6 to

$7.5, but in Mary’s opinion, the selling price can only be increased by $1 to maintain the existing sales volume.

Should I buy the cake shop in view of the new information?

Eric is now thinking of another situation. Students are required to follow the similar approach used in Activity 1 and 2 to make recommendations to Eric whether he should buy the cake shop or not.

There are changes in variable costs and the selling price, which leads to a change in unit contribution. Change in unit contribution will then lead to change in break-even point, monthly profit, margin of safety and the rate of return. Students are required to make recommendation based on the figures arrived at in student worksheets p.5-6.

z

### Recommendation

z

### Acquire the business.

If the supplier does not increase the price, which is high at an 80% chance, the rate of return and the margin of safety is 20% and 25% respectively.

This is a very good investment with high rate of return and the risk involved is low.

Even if the supplier does increase the price, which is low at a 20% chance, the rate of return and the margin of safety is 10% and 14.29% respectively.

This is still a good investment as the return is reasonable and the risk involved is acceptable with 14% on margin of safety.

**Activity 4 - Eric’s wrong ** **concept**

z

### Mixes up variable costs with fixed costs and draws a wrong conclusion.

z

### A variable cost is a cost that varies with some measure of output or activity.

z

### A fixed cost is a cost that, in total, remains constant for a specified time period.

This is a common mistake made by students.

The relevant cost is the variable cost which will increase as the sales volume increases. Fixed costs are period costs and will not increase when sales volume increases.

**Activity 4 - Correct approach**

z The fixed cost $30,000 per month will not increase even if the sales volume is increased by 10,000 units.

z Correct approach

z compare the additional contribution with the additional expenditure.

z Incremental profit

z = Additional contribution – Additional expenditure

z = 10,000 units * $4 - $10,000 = $30,000 z Recommendation : Implement the proposal

A fixed cost is a cost, that in total, remains constant for a specified time period and will not be affected by the change in sales volume. Here the shopkeepers’ salary, the monthly rental and other fixed costs will remain the same when the sales volume increases by 10,000 units.

The relevant cost is the variable costs which varies linearly with the change in sales volume. The correct approach is to compare the incremental contribution with incremental expenditure to determine whether there is incremental profit or not.

**Activity 4 – Key Points Learned**

z

### Different behavior of Variable costs and Fixed costs.

z

### Comparing additional contributions with additional expenditures in making a decision.

Students should be aware that only the variable costs, but not fixed costs, are the relevant costs for decision making in this case.

Most of the time, as the variable cost varies with the change in sales volume, we should compare incremental contributions with incremental expenditures in order to determine the profit or loss for decision making.

Teacher concludes the lesson by reviewing the key points learned.

Key points learned include:

1. CVP analysis concerns with analysis within a relevant range and for short run.

2. Costs can be divided into variable and fixed elements.

3. The unit selling price and unit variable cost remain constant.

4. A fixed cost is a cost, that in total, remains constant for a specified time period.

5. The different cost behavior of variable cost and fixed cost.

6. The formulae in calculating profit and break-even point.

To prepare for the next lesson, students must study the questions and answers distributed in this lesson and ask the teacher to clarify areas they do not understand. The case in lesson 1 will continue in lesson 2 and the thorough understanding of the materials in lesson 1 is vital for them to answer questions in lesson 2.

### 2. Calculate revised monthly break-even point 3. Calculate revised margin of safety in units & % 4. Calculate revised annual profit

### 5. Calculate revised annual rate of return 6. Determine the risk of the business and the

### reasonableness of the return in the new situation

### 7. Make your recommendation

This is a very straight forward question and it serves as a warm up exercise for students.

Teacher should encourage students to complete these questions to evaluate how much they have learned in lesson one.

Fixed cost is changed which leads to a change in break-even point, margin of safety, contribution, profit earned and rate of return.

**Activity 6 –**

**Adding chocolate mix topping on the cake**

z

### Eric has a plan to develop his business by selling a new style cake with chocolate topping.

z

### Selling price, unit variable costs, monthly fixed costs and sales volume will be changed.

z

### Advise Eric whether he should carry out his plan.

This is a complicated CVP analysis with changes in all the elements, i.e.

selling price, sales volume, unit variable costs and monthly fixed costs.

Teacher asks students to follow the steps on the next slide in solving this business problem. Students can also refer to student worksheets p.12-14 for details.

**Steps for Activity 6**

### 1. Calculate the new variable cost and monthly fixed cost for the new product if it is launched.

### 2. Calculate the break-even point, margin of safety in units and in percent, annual profit and rate of return if the new product is launched.

### 3. Compare results to results arrived at in Activity 5.

### 4. Make recommendations to Eric.

For Step 1

Teacher asks students to think whether the chocolate mix, baker’s salary and the cost of flyers are variable costs or fixed costs, and then calculate the unit contribution and the monthly fixed costs.

For Step 3

Teacher asks students that annual profit, rate of return and margin of safety should be compared.

### Eric phones you one day and says that he would like to earn the same amount of profit as last year’s ($120,000) and plans to boost sales more by staying in the cake shop on weekends.

z

### Advise Eric

Students can refer to student worksheet p.15 for details.

In this situation, to determine the required sales units to maintain a certain profit, students should add the target profits with the fixed costs to determine the total amount. Then, they divide this amount by the unit contribution to find out the sales units.

### Qualitative factors to be considered before making decisions.

Teacher concludes this lesson by reviewing the key points.

Teacher should emphasise that the CVP analysis uses the principles of marginal costing and is best suited to short run problems; it explores the relationship which exists among costs, revenue, output levels and resulting profit and is more relevant where the proposed changes in the levels of activity are relatively small.
