Contribution Margin - Examples

Examples

Here's an example of a contribution format income statement:

Beta Sales Company Contribution Format Income Statement For Year Ended December 31, 201X
Sales $ 462,452
Less Variable Costs:
Cost of Goods Sold
Sales Commissions
Delivery Charges
$ 230,934
$ 58,852
$ 13,984
Total Variable Costs $ 303,770
Contribution Margin (34%) $ 158,682
Less Fixed Costs:
Advertising
Depreciation
Insurance
Payroll Taxes
Rent
Utilities
Wages
$ 1,850
$ 13,250
$ 5,400
$ 8,200
$ 9,600
$ 17,801
$ 40,000
Total Fixed Costs $ 96,101
Net Operating Income $ 62,581

The Beta Company's contribution margin for the year was 34 percent. This means that, for every dollar of sales, after the costs that were directly related to the sales were subtracted, 34 cents remained to contribute toward paying for the indirect (fixed) costs and later for profit.

Contribution format income statements can be drawn up with data from more than one year's income statements, when a person is interested in tracking contribution margins over time. Perhaps even more usefully, they can be drawn up for each product line or service. Here's an example, showing a breakdown of Beta's three main product lines:

Line A Line B Line C
Sales $120,400 $202,050 $140,002
Less Variable Costs:
Cost of Goods Sold $70,030 $100,900 $60,004
Sales Commissions $18,802 $40,050 $0
Delivery Charges $ 900 $ 8,084 $ 5,000
Total Variable Costs $ 89,732 $ 149,034 $ 65,004
Contribution Margin $ 30,668 $ 53,016 $ 74,998
percentage 25% 26% 54%

Although this shows only the top half of the contribution format income statement, it's immediately apparent that Product Line C is Beta's most profitable one, even though Beta gets more sales revenue from Line B(which is also an example of what is called Partial Contribution Margin - an income statement that references only variable costs). It appears that Beta would do well by emphasizing Line C in its product mix. Moreover, the statement indicates that perhaps prices for line A and line B products are too low. This is information that can't be gleaned from the regular income statements that an accountant routinely draws up each period.

Famous quotes containing the word examples:

    Histories are more full of examples of the fidelity of dogs than of friends.
    Alexander Pope (1688–1744)

    It is hardly to be believed how spiritual reflections when mixed with a little physics can hold people’s attention and give them a livelier idea of God than do the often ill-applied examples of his wrath.
    —G.C. (Georg Christoph)

    In the examples that I here bring in of what I have [read], heard, done or said, I have refrained from daring to alter even the smallest and most indifferent circumstances. My conscience falsifies not an iota; for my knowledge I cannot answer.
    Michel de Montaigne (1533–1592)
