Product’s Contribution Margin Ratio: Product Contribution margin ratio is commonly expressed as a percentage of sales prices. It is the difference between a company’s sales and variable expenses, expressed as a percentage. It is one of the most important ratios for studying the profitability of operations of a business and establishes the relationship between contribution and sales. A higher ratio means a greater profitability and vice versa.

(Sales – Variable expenses) ÷ Sales
