The answers could also have been determined by preparing a statement of profit or loss. Using the
first table (row 1) above:
Sales (5000 × $40)
Less: Variable costs
Contribution margin
Fixed costs
Profit
$200 000 (given)
Not given
Not given
60 000 (given)
40 000 (given)
To calculate contribution margin we would need to add fixed costs and profit. Why would we
do this? Because we know that contribution margin is equal to fixed costs in the first instance,
with any additional contributing towards profits. Therefore, the contribution margin is $100 000
($60 000 + $40 000). To calculate the variable costs we know that sales less contribution margin
are equal to variable costs. In our example, if sales are $200 000 with a contribution margin of
$100 000 then variable costs are $100 000, and given that 5000 units were sold, the variable cost
per unit is $20 ($100 000/5000 units).
10.2 Sigrid Enterprises operates a single-product entity. Data relating to the product for 2016 are as follows.

Required
a. Calculate total fixed costs and total variable costs per unit.
b. Calculate the break-even units for 2016.
c. Changes in marketing strategy are planned for 2017. This would increase variable marketing
and distribution costs by $4 per unit, and reduce fixed non-manufacturing costs by $60 000 per
year. Calculate the break-even units for 2017 under the new marketing strategy.
