2.1.4 Contribution margin

The contribution margin on the products we supply, or the services we provide, is the sell price less the variable cost, using the formula beneath:

Contribution margin = sell price - variable costs.

In the Creek Clothing example:

The contribution margin helps us to work out how much each unit sold contributes to profit, without taking into account the fixed costs. In order to work out how many pairs of socks need to be sold to break even you may use the formula beneath:

Break even units = Fixed Costs

Contribution Margin per unit

In the Creek Clothing example:

Break even = $1000 = 200

$5

In this case we would need to sell 200 pairs of socks to break even. This is the same figure that we obtained with the previous table.

You might also like to calculate how much revenue you need to earn to break even. This is obtained by multiplying the number of units that need to be sold by the sell price of those units, or by using the following formula:

Break even revenue = break even units x sell price per unit

In the Creek Clothing example:

200 Pairs X $6 Sell Price = $1200

This means that $1200 in sales is required before the business starts to earn profit.

Activity 2

  1. Explain the difference between contribution margin and Gross Profit

    The Creek Clothing Company accountant has given us the company results for the year and has asked you to do some work.

    Company Revenue $ 360,000
    Fixed Cost $ 195,000
    Variable Cost $ 180,000
    Total number of units produced = 90,000
  2. What is the contribution margin for each unit produced ?
  3. What is the Creek Clothing Company's break-even point in units?
  4. What is the Creek Clothing Company's break- even point in sales revenue $'s?
  5. Using this information to work on the graph over the page, complete the following:

    The Creek Clothing Company would like to upgrade their factory and production line to improve efficiency and reduce direct labour costs. From the initial research done by the engineers at Creek Clothing Company the upgrades will increase the fixed costs by $9000, however variable costs will be reduced by $1 per unit and sales revenue will remain at $360,000 (for 90,000 units).
