: Contribution margin ratio and its uses in planning business operations

Answer to Problem 1Q

Solution: A contribution margin is the amount available for coverage of fixed expenses of the business operations. When the contribution margin is expressed in percentage of sales, it is called a contribution margin ratio. It is helpful in fixing a price for a product and analyzing the impacts of revenue at different level of unit sales.

Explanation of Solution

: In simple words, a contribution margin is the difference between the sales revenue and variable cost of the product. A contribution margin ratio represents the percentage of sales revenue for meeting the fixed expenses of business operations. A company can predict or estimate its operating income based upon the contribution margin ratio. A negative or low contribution margin indicates low opportunity for making profit and high risk of loss.

For Example, if the selling price per unit of a product is $10 and variable expenses per unit is $6, the contribution margin ratio will be:

  $$

  $\begin{array}{l}Contributionmarginratio=\frac{Contributionmarginperunit}{Sellingpriceperunit}\hfill \\ =\frac{\$4}{\$10}\hfill \\ =0.40or40\%\hfill \\ *Contributionmargin=Sellingpriceperunit–Variableexpensesperunit\hfill \\ =\$10-\$6\hfill \\ =\$4\hfill \end{array}$

Conclusion

: A contribution margin is computed by deducting the variable expenses from the sales revenue of the company. The contribution margin ratio is ascertained by dividing the contribution margin with sales revenue of the company. As the contribution margin is used for meeting the fixed expenses, hence, the higher the contribution margin ratio, there is a better chances that the company might make handsome income from operations.
