What is the Contribution Margin Income Statement?
Contribution margin income statements refer to the statement which shows the amount of contribution arrived after deducting all the expenses that are variable in nature from the total revenue amount and further fixed expenses are deducted from the contribution to get the net profit/loss of the business entity.
It is a special format of the income statement that segregates the variable and fixed expenses involved in running a business. It shows the revenue generated after deducting all variable and fixed expenses separately. In simple words, this format expresses the revenue generated after paying all the variable costs.
- The Contribution Margin Income Statement format has fixed expenses as a part of overhead costs instead of production costs. To explain it in a better way, fixed expenses incur even if the sales volumes go up or down. Hence they are independent of what the sales are. However, the variable expenses tend to shoot as the production increases.
- All we need to do is deduct the variable expenses from revenue, which would give contribution margin as a result. From the contribution margin, when we deduct all fixed expenses, it concludes to Net Profit or Net Loss.
- It cannot be used for Generally Accepted Accounting Principles (GAAP) statements and is used by managers internally. This format is handy in decision making. It helps in understanding the cost behavior by separating the fixed and variable expenses.
Contribution Margin Income Statement Format:
Every dollar of revenue generated goes into either of Contribution Margin or Variable Costs. What’s left in contribution margin goes in covering Fixed Costs and remaining into the Net Profit / Loss.
Unlike a traditional income statement, the expenses are bifurcated based on how the cost behaves. Variable cost includes direct material, direct labor, variable overheads, and fixed overheads. It does not matter if your expenses are production expenses or selling and administrative expenses. If they are variable, they must be included in variable costs. The same thing goes with fixed expenses; if they are fixed, they must be included in fixed costs.

The contribution margin and the variable cost can be expressed in percentage of the Revenue. These are called the contribution margin ratio and variable cost ratio, respectively.
Examples of Contribution Margin Income Statement
Example #1
‘My Cake Shop’ is a cake and pastry business that you run. With the rising demand in customers asking for workshops for baking their cakes, you started weekend workshops for the same. The revenue generated for the month was $7,500, which included direct sales of $6,000, and income from conducting Weekend Cake Workshops was $1,500. Wages paid were $2,000, and the expense incurred in procuring materials summed up to a total of $1,500. Rent of $1,000 was paid, and the insurance premium payment of $200 was also made. The contribution margin income statement would look like this:
Example #2
Last month, Vienna Inc. sold its product for $2,000 per unit. The fixed production costs were $3,000, and fixed selling and administrative costs were $50,000. Variable production costs were $1,000 per unit, and variable selling and administrative costs were $500 per unit. Vienna Inc. sold 500 units for the previous month.
Prepare a contribution margin income statement.
Calculation:
- Sales = Selling price per unit x No. of units sold =$2,000 x 500 =$1,000,000
- Cost of Goods Sold = $1,000 x No. of units sold =$1,000 x 500 =$500,000
- Selling and administrative costs = $500 x No. of units sold =$500 x 500 =$250,000
Contribution Margin Ratio
Contribution Margin Ratio = (250,000 / 1,000,000) x 100
Contribution Margin Ratio = 25%
Variable Cost Margin Ratio
Variable Cost Margin Ratio = (750,000 / 1,000,000) x 100
Variable Cost Margin Ratio = 75%
