What is contribution margin? In accounting contribution margin is defined as revenues minus variable expenses. In other words, the contribution margin reveals how much of a company's revenues will be contributing (after covering the variable expenses) to the company's fixed expenses and net income.
To calculate breakeven in dollars, divide its fixed expenses by the contribution margin ratio of 60% ($60,000/.6 = $100,000). This means that the company has to make $100,000 in sales to breakeven. The contribution margin ratio is an important financial metric to calculate the profit potential for a business firm.If the dollar amount of sales increases by one dollar, in this example, the contribution margin increases by 60 cents.he contribution margin ratio is the contribution margin as a percentage of total sales. Use the following formula to calculate the contribution margin ratio: Contribution Margin Ratio = Contribution Margin/Sales. Here is an example using break-even analysis :
