Contribution margin definition


Contribution margin allows the company to evaluate the profitability of individual products. In other words, this ratio determines how much each sale contributes to fixed expenditures. Data to calculate this ratio is collected from the income statement and additional management accounting statement (if such is used).

Contribution margin is mostly used by company’s management while making a decision whether to launch a new product or not.
