Financial statements are prepared for various stakeholders (both internal and external) to gauge the financial performance as well as the entity’s financial health for a specific period. Financial statements largely consist of income statement, cash and fund flow statements and balance sheet. The income statement reports all the revenues and expenses of the business for the specific accounting period so as to arrive at the net profitability for the period. Revenues and expenses can be bifurcated in different manners such as fixed and variable, direct and indirect, department wise etc. The manner in which the revenues and expenses are presented in the income statement determines the type of income statement prepared.
The article “traditional vs contribution margin income statement” looks at meaning of and differences between two types of presentation of income statements – traditional income statement and contribution margin income statement.
Definitions and meanings
Traditional income statement
The traditional income statement is a profitability statement that bifurcates and reports revenues and expenses on the basis of their relation with production activity i.e., direct and indirect. It reports two levels of profit:
- Gross profit that reflects the difference between production related revenues and expenses; and
- Net operating income that reflects the residual profit after consideration of gross profit and other indirect revenues and expenses.
Effectively, this income statement can be bifurcated into a manufacturing or trading account which reports the gross profit and the profit and loss account which reports the net profit or net operating income.
The simplest format of a traditional income statement looks like the following:
Revenues realized during 2020:
- Units manufactured and sold during 2020: 2,000 units
- Sale price: $30 per unit
- Total sales revenue realized: (2,000 units × $30): $60,000
Expenses incurred during 2020:
- Variable manufacturing expenses: $12 per unit
- Variable selling and administrative expenses: $4 per unit
- Fixed manufacturing expenses: $6,000 per month
- Fixed marketing and administrative expenses: $2,000 per month
Roberts has no finished goods and work in process inventory.
The traditional income statement prepared for the above would be as follows:
The above is an example of a traditional income statement prepared in a columnar format. The same can also be prepared in ‘T’ form.
Contribution margin income statement
The contribution margin income statement is a profitability statement that reports the entity’s contribution margin and net operating income, by bifurcating expenses on the basis of their variability. The key point to note here is that the expenses are bifurcated into fixed and variable and accordingly reported in the income statement.
This statement reports two levels of profit:
- Contribution margin which is arrived at by deducting all variable expenses from the total revenue.
- Net operating income which is arrived at by deducting all fixed expenses from the contribution margin.
Below is the simplest format of a contribution margin income statement:
Continuing with the above revenue and expense data of Roberts Company, the contribution margin income statement can be prepared as follows:
While the net profit in this example is the same for both types of income statements, this may not always be the case. In circumstances where opening and closing inventory differ, the net profit reflected in both the income statements would also differ. This is on account of charge of fixed costs. While the entire fixed cost incurred in the period would be charged in the contribution margin statement, the same would be adjusted for opening and closing inventories in the traditional income statement.
