Contribution margin ratio
Contribution margin ratio (CM ratio) is the ratio of contribution margin to net sales. It tells what percentage of sales revenue is available to cover fixed cost and generate profit.
Contribution margin ratio is calculated by dividing contribution margin figure by the net sales figure. The formula can be written as follows:
The ratio is also shown in percentage form as follows:
The numerator of the formula i.e., contribution margin can be calculated using simple contribution margin equation or by preparing a contribution margin income statement.
The total sales revenue of Black Stone Crushing Company was $150,000 for the last year. The fixed and variable expenses data of the last year is given below:
Marketing and administrative: $30,000
Marketing and administrative: $8,000
Required: Calculate contribution margin ratio and also express it in percentage form.
Contribution margin = $150,000 – ($60,000 + $30,000)
= $150,000 – $90,000
Contribution margin ratio = $60,000/$150,000
Contribution margin percentage = ($60,000/$150,000) × 100
The contribution margin is 40% which means 40% of the total net sales revenue generated during the year is available to cover all fixed expenses as well as generate profit for the business.
The Monster company manufactures and sells two products. The data relating to sales and expenses for the last six months is given below:
The total fixed expenses for the last six months were $60,000. Out of these fixed expenses, 50% were manufacturing and remaining 50% were related to marketing and administrative activities. There were no any beginning and ending inventories.
Required: Which product has the higher contribution margin ratio?
Product A’s contribution margin ratio is 0.42 or 42% where as product B’s contribution margin ratio is 0.5 or 50%. Product B is contributing more for covering fixed expenses and generating profit because its contribution margin ratio is higher than that of product A.
