What is the contribution margin?
The Contribution Margin represents each unit’s contribution to the company’s profit, calculated as the selling price minus the variable cost per unit. These variable costs could include raw materials, fuel, and labor expenses per unit sold.
A business may have multiple product lines, and the CM is calculated for each product separately.
Contribution Margin of a company
Companies sell products or services, and businesses always aim to maximize their profit. Hence, the business needs to determine the profit it makes on the products or services it sells. Typically, every business’s expenses can be classified into fixed expenses, which it will incur even if there are no sales, and variable expenses, which will vary depending on the number of units sold. Knowing the exact value of these fixed and variable expenses will help companies control them and improve their profits.
How to calculate contribution margin
Contribution Margin Formula
Contribution Margin = P – V
P is the product’s sales price, V is the variable expenses for the specific product, and the margin is calculated in dollar terms. In an alternate formula, the contribution margin ratio may also be calculated as a percentage or a fraction of the sales price.
Contribution Margin Formula
The contribution margin can be calculated in two primary ways:
- Contribution Margin per Unit:
This tells you how much each unit sold contributes to covering fixed costs and generating profit. - Total Contribution Margin:
He gives the overall contribution margin for a period, showing how much revenue is available to cover fixed costs and contribute to profit.
Contribution Margin Ratio
The contribution margin ratio expresses the contribution margin as a percentage of sales revenue:
This ratio helps understand the proportion of sales revenue contributing to fixed costs and profit.
Example Calculation
Let’s walk through an example to illustrate these calculations:
- Determine the Selling Price per Unit and Variable Costs per Unit:
- Selling Price per Unit: $50
- Variable Cost per Unit: $30
- Calculate the Contribution Margin per Unit:
So, each unit sold contributes $20 towards covering fixed costs and profit. - Determine Total Sales Revenue and Total Variable Costs:
- Total Sales Revenue: $500,000
- Total Variable Costs: $300,000
- Calculate the Total Contribution Margin:
This means $200,000 is available to cover fixed costs and generate profit. - Calculate the Contribution Margin Ratio:
This indicates that 40% of each dollar of sales revenue contributes to covering fixed costs and profit.
Importance of Contribution Margin
- Pricing Decisions: Helps set prices by understanding how much profit is generated per unit.
- Cost Control: Identifies variable costs and their impact on profitability.
- Profitability Analysis: Assists in evaluating which products or services are most profitable.
- Break-Even Analysis: This is essential for determining the break-even point where total revenue equals total costs.
By regularly calculating and analyzing contribution margins, businesses can make more informed decisions to improve their financial performance.
How to calculate the contribution margin ratio
Unit contribution margin/Price = ( P – V) /P = Total contribution margin / Total revenues
After deducting the variable costs, the amount available will help offset the business’s fixed costs and contribute to the profit. The contribution margin determines the slope of the profit line, which is how many units must be sold to make a profit.
What is a Good Contribution Margin?
It is better if the contribution margin percentage or contribution margin ratio is close to 100%. The higher the contribution margin ratio, the more money is available to cover the business’s overhead expenses or fixed costs.
A business usually pays all its expenses and profits from its sales income. Some business expenses are directly proportional to the number of units of products or services being sold. Sales revenues also help cover the fixed expenses of the business, like the cost of land and machinery. The contribution margin is the amount in which the sale of each unit contributes to the company’s profit and helps the company pay for the fixed expenses for running the business.
Now, we have a practical question:
How is the contribution margin ratio helpful in planning business operations?
- It can be used in cost-profit calculations.
- It can be used in target profit analysis
- It can be used in break-even analysis
- It can quickly estimate the effects of a change in sales revenue on profits.
The contribution margin is used extensively in management accounting to determine the business’s break-even point. Companies periodically analyze the cost of each unit, the volume of units, and the profit they are making to calculate net income. This information is also used to fix the sales team’s targets and determine the structure of the bonuses or commissions for the sales team. In addition, the margin can be used to determine the prices for the services or products sold based on market conditions like demand.
The business can decide whether to retain or remove a product line based on its contribution margin. If a product line has a positive contribution margin, it is retained, even if there is a loss after considering fixed costs, since the product line helps to offset the fixed costs. On the other hand, most businesses will be forced to close a production line with a negative contribution margin for a long time since it adds to the business losses and is not sustainable in the long term.
The contribution margin analysis provides details of the company’s leverage since it sells goods or services. It indicates the relationship between the company’s sales increase sales and the growth in the business’s profit. For management accounting purposes, the income statement is reformatted to group the variable costs and fixed costs separately, and this statement is called the statement for contribution income. This statement will provide details of the contribution margin of each product or service sold. The contribution margin differs from the gross margin, which is calculated using accounting standards since the contribution margin is calculated after analyzing the nature of the expenses.
How to calculate the break-even point using the contribution margin:
Break-even point= Fixed expenses – Contribution margin per product
Other applications
In many countries, the tax authorities also check the contribution margin of the business while investigating whether the business is paying the due taxes. Companies with a higher contribution margin ratio than other companies in the same industry sector are often shortlisted for tax investigations to determine why the company is making more profit. Also, companies with a monopoly or near-monopoly in their sector often have a high contribution margin since there is little or no competition. Hence, the government may use competition law against these companies.
Services and products
It is usually observed that manufacturing companies have a high fixed cost since they have to invest large amounts in land, construction, machinery, and other equipment. Hence, they will price the products they are manufacturing at a price that gives them a high contribution margin. This margin is then used to cover the fixed expenses. On the other hand, the companies selling services usually do not have to invest a significant amount in machinery or property. Therefore, since the competition for service providers is high, these companies have a lower contribution margin, though it may vary depending on the specific service.
Conclusion
The Contribution Margin is an essential parameter for any business since it helps it decide whether it is making a profit on every unit sold. While the overall profit depends on both the fixed and variable expenses, the contribution margin determines whether it is viable for the business to make and sell it. If the contribution margin is low, the company may try to reduce the expenses for the product or increase the price of the product. The parameter is also essential for setting the sales target for the business to break even or make a profit.
