Contribution margin

Contribution margin is a business’s sales revenue less its variable costs. The resulting contribution dollars can be used to cover fixed costs (such as rent), and once those are covered, any excess is considered earnings. Contribution margin (presented as a % or in absolute dollars) can be presented as the total amount, amount for each product line, amount per unit, or as a ratio or percentage of net sales.

What Is Contribution Margin?

The contribution margin can be stated on a gross or per-unit basis. It represents the incremental money generated for each product/unit sold after deducting the variable portion of the firm’s costs.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.It provides one way to show the profit potential of a particular product offered by a company and shows the portion of sales that helps to cover the company’s fixed costs. Any remaining revenue left after covering fixed costs is the profit generated.

Formula and Calculation of Contribution Margin

The contribution margin is computed as the difference between the sale price of a product and the variable costs associated with its production and sales process. This is expressed through the following formula:

C=R−V

Where is the contribution margin, is the total revenue, and represents variable costs.

It may also be useful to express the contribution margin as a fraction of total revenue. In this case, the Contribution Margin Ratio (CR) is expressed as the contribution margin, divided by total revenues in the same time period:

CR=(R−V)R

What Contribution Margin Can Tell You

The contribution margin is the foundation for break-even analysis used in the overall cost and sales price planning for products. The contribution margin helps to separate out the fixed cost and profit components coming from product sales and can be used to determine the selling price range of a product, the profit levels that can be expected from the sales, and structure sales commissions paid to sales team members, distributors, or commission agents.

Fixed Cost vs. Variable Cost

One-time costs for items such as machinery are a typical example of a fixed cost that stays the same regardless of the number of units sold, although it becomes a smaller percentage of each unit’s cost as the number of units sold increases.Other examples include services and utilities that may come at a fixed cost and do not have an impact on the number of units produced or sold. For example, if the government offers unlimited electricity at a fixed monthly cost of $100, then manufacturing 10 units or 10,000 units will have the same fixed cost towards electricity. In these kinds of scenarios, electricity will not be considered in the contribution margin formula as it represents a fixed cost. However, if the electricity cost increases in proportion to consumption, it will be considered a variable cost.

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.

Contribution Margin vs. Gross Profit Margin

The contribution margin is different from the gross profit margin, the difference between sales revenue and the cost of goods sold. While contribution margins only count the variable costs, the gross profit margin includes all of the costs that a company incurs in order to make sales.The contribution margin shows how much additional revenue is generated by making each additional unit product after the company has reached the breakeven point. In other words, it measures how much money each additional sale “contributes” to the company’s total profits.

Uses of Contribution Margin

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.

If the contribution margin for an ink pen is higher than that of a ball pen, the former will be given production preference owing to its higher profitability potential. Such decision-making is common to companies that manufacture a diversified portfolio of products, and management must allocate available resources in the most efficient manner to products with the highest profit potential.

How to Improve Contribution Margin

Based on the contribution margin formula, there are two ways for a company to increase its contribution margins; They can find ways to increase revenues, or they can reduce their variable costs.Variable costs tend to represent expenses such as materials, shipping, and marketing, Companies can reduce these costs by identifying alternatives, such as using cheaper materials or alternative shipping providers.Alternatively, the company can also try finding ways to improve revenues. For example, they can increase advertising to reach more customers, or they can simply increase the costs of their products. However, these strategies could ultimately backfire and result in even lower contribution margins.

FAQs

Why is Contribution Margin Important?

Contribution Margin is crucial for assessing the profitability of individual products or services. It helps in determining the amount available to cover fixed costs and contribute to the company’s profit.

What is the Significance of Contribution Margin Ratio?

The Contribution Margin Ratio is expressed as a percentage and is calculated by dividing the Contribution Margin by the Total Sales Revenue. It helps in analyzing the efficiency and profitability of the business.

Can Contribution Margin be Negative?

Yes, Contribution Margin can be negative if variable costs exceed total sales revenue. This indicates that the product or service is not covering its variable costs.
