# Cost Assumptions

Cost Assumptions

1. Production of 1500 units, total sales DM 180,000

Selling price per unit =180,000/1500=120

Income statement

 Sales 180,000 Less Variable Costs 69,000 Contribution to Margin (Sales-variable costs) 111, 000 Less Fixed Costs 140, 000 Net Profit -29, 000

Total variable cost (31+15)*1,500=69,000)

1. There is a special order of 400 units to be sold at DM50.

Computation of the new income statement

Income statement

 Sales (180,000+20,000) 200,000 Less Variable Costs (1500+400*46) 87,400 Contribution to Margin (Sales-variable costs) 112,600 Less Fixed Costs 140, 000 Net Profit -27,4000

1. Compute the number of units the company should sell to achieve the targeted income

Sales to earn DM 30,000

= (fixed cost+ target profit) /contribution margin for each unit

Fixed costs=90,000+50,000=140,000

Target profit=30,000

Therefore, the number of units the company should sell to get a net income of  DM 30,000 is computed as follows; (fixed cost+ target profit) /contribution to margin for each unit

= (140,000+30,000)/ (120-46)

= 170,000/74

=2297.297 units

Therefore, the company should produce 2297 units to realize a net income of DM 30, 000

1. Explain what will happen when variable costs are increased or decreased

a). If the variable cost is increased, then more units will be required to achieve the targeted income. Let us assume that the variable cost is increased to 60.

The number of units will be as follows;

= (140,000+30,000)/ (120-60)

=170,000/60

=2833.33

The number of units that should be sold will be 2833 to realize a profit of DM30, 000.

B). On the other hand, if the variable costs are decreased, then less units will be sold to realize a profit of DM 30, 000 as shown below;

Lest assume the variable cost is decreased to say, 30

The number of units will be calculated as follows

(140,000+30,000)/ (120-30)

=170,000/90

=1888.88

Therefore, 1889 units should be sold to realize a profit of DM 30, 000.

1. What happens when the fixed costs are increased or decreased

When the fixed costs are decreased, then fewer units should be sold to realise the set target. The reverse is also true.

a). Let us assume the fixed costs are decreased to 120,000

The number of units will be calculated as follows

(120,000+30,000) / (120-46)

=2027.027

Therefore, 2027 units should be sold to have profits of DM 30, 000.

b). Lets assume that fixed cost are increased to 150, 000

The number of units will be calculated as follows

(150, 000+30, 000)/ (120-46)

=180, 000/74

=2432.43

Therefore, 2432 units should be sold

F). what happens when the selling price is increased by 10%, while other cost remain constant

 Sales (180,000+18,000) 198,000 Less Variable Costs (1500*46) 69,000 Contribution to Margin (Sales-variable costs) 129,000 Less Fixed Costs 140, 000 Net Profit -11,000

In this case, the loss goes down.

Limitation: It is assumed that the selling price and fixed costs are the same

G). Assume the capacity and sales are double to 4, 800 unit. Compute the net income if facilities costing 500, 000 DM are added at 5-year life

 Sales (4,800*120) 576,000 Less Variable Costs (4800*46) 220,800 Contribution to Margin (Sales-variable costs) 355,200 Less Fixed Costs (100,000+140000 240,000 Net Profit 115,200

The selling price is DM120 and the fixed cost has been increased by 100, 000 DM, which is calculated as follows;

The cost of the facilities/ life

=500,000/5

=DM 100,000
