That is it does not include any deductions like sales return and allowances. Thus, the total variable cost of producing 1 packet of whole wheat bread is as follows. Contribution margin calculation is one of the important methods to evaluate, manage, and plan your company’s profitability.

Cost accountants, FP&A analysts, and the company’s management team should use the contribution margin formula. CM is used to measure product profitability, set selling prices, decide whether to introduce a new product, discontinue selling a product, or accept potential customer orders with non-standard pricing. If all variable and fixed costs are covered by the selling price, the breakeven point is reached, and any remaining amount is profit. That can help transform your labor costs from a variable expense to a fixed expense and allow you to keep those expenses under tighter control. As a result, your variable expenses will go down and your contribution margin ratio will go up.

The companies that operate near peak operating efficiency are far more likely to obtain an economic moat, contributing toward the long-term generation of sustainable profits. The calculation of the contribution margin ratio is a three-step process. When comparing any two common size ratios, it is important to make sure that they are computed by using the same base figure. Common size ratios can be very useful when trying to get a better understanding of a business.

Product B is contributing more for covering fixed expenses and generating profit because its contribution margin ratio is higher than that of product A. A company has revenues of $50 million, the cost of goods sold is $20 million, marketing is $5 million, product delivery fees are $5 million, and fixed costs are $10 million. The financial reports that accounting ratios are based on represent much of the core essence of a business. They paint a picture of where a company came from, how they are doing currently, and where they are going into the future. The ratios may seem simple at first, but they are incredibly nuanced and can be difficult to calculate once one is attempting to analyze and quantify Fortune 500 companies. The same methodology can also be applied to the business’ other financial statements in order to get a different perspective.

You can also consider various pricing methods to increase your contribution margin without losing customers. Unfortunately, increasing your prices and investing more in marketing can result in lower contribution margins if you’re not careful. For instance, if you spend too much on advertising without any growth in sales, you’ll have a lower contribution margin. Fixed costs are often considered sunk costs that once spent cannot be recovered. These cost components should not be considered while taking decisions about cost analysis or profitability measures. Thus, it will help you to evaluate your past performance and forecast your future profitability.

However, this strategy could ultimately backfire, and hurt profits if customers are unwilling to pay the higher price. The contribution margin can help company management select from among several possible products that compete to use the same set of manufacturing resources. Say that a company has a pen-manufacturing machine that is capable of producing both ink pens and ball-point pens, and management must make a choice to produce only one of them.

How to Calculate Contribution Margin

That is, it refers to the additional money that your business generates after deducting the variable costs of manufacturing your products. The contribution margin reflects a company’s profitability on each unit sold. A contribution margin is important because it shows how much money is available to pay the fixed costs such as rent and utilities, that must be paid even when production or output is zero. The contribution margin (CM) ratio is the ratio of the total contribution margin to total sales revenue. It is used in target profit and break-even analysis and can be used to quickly estimate the effect on profits of a change in sales revenue.

The contribution margin is computed as the selling price per unit, minus the variable cost per unit. Also known as dollar contribution per unit, the measure indicates how a particular product contributes to the overall profit of the company. Consider the following contribution margin income statement of XYZ private Ltd. in which sales revenues, variable expenses, and contribution margin are expressed as percentage of sales. A contribution margin ratio of 40% means that 40% of the revenue earned by Company X is available for the recovery of fixed costs and to contribute to profit.


Many companies have fixed and variable costs that change from product to product and month to month. Knowing how your costs affect your profits is crucial to understanding your business’s financial health. To calculate contribution margin, a company can use total revenues that include service revenue when all variable costs are considered. For each type of service revenue, you can analyze service revenue minus variable costs relating to that type of service revenue to calculate the contribution margin for services in more detail.

Therefore, the unit contribution margin (selling price per unit minus variable costs per unit) is $3.05. The company’s contribution margin of $3.05 will cover fixed costs of $2.33, contributing $0.72 to profits. The Contribution Margin Ratio is a measure of profitability that indicates how much each sales dollar contributes to covering fixed costs and producing profits. It is calculated by dividing the contribution margin per unit by the selling price per unit. The contribution margin ratio is the difference between a company’s sales and variable costs, expressed as a percentage. This would increase the variable costs by $1 per unit, bringing the variable cost per unit to $5.

Formula of CM Ratio (Contribution Margin Ratio Formula):

Profit margin is calculated using all expenses that directly go into producing the product. Say, your business manufactures 100 units of umbrellas incurring a total variable cost of $500. Accordingly, the Contribution Margin Per Unit of Umbrella would be as follows. Fixed costs are the costs that do not change with the change in the level of output. In other words, fixed costs are not dependent on your business’s productivity. In 2022, the product generated $1 billion in revenue, with 20 million units sold, alongside $400 million in variable costs.

You need to calculate the contribution margin to understand whether your business can cover its fixed cost. Also, it is important to calculate the contribution margin to know the price at which you need to sell your goods and services to earn profits. The first step to calculate the contribution margin is to determine the net sales of your business. Net sales refer to the total revenue your business generates as a result of selling its goods or services. Contribution margin is used to plan the overall cost and selling price for your products.
