What is Contribution Margin Ratio? What is the formula and why it is important

Contribution margin ratio is an important concept that may seem complex but can be quite straightforward. It’s a key measure that reflects the core profitability of each product or service offered by a business and serves as an aid to understanding overall financial health. By taking into account both variable costs and fixed costs associated with making a sale, this measure helps identify if the cost structure of goods and services is sustainable in balance with their revenue stream.

What is the Contribution Margin Ratio?

The Contribution Margin Ratio (CMR) is a financial ratio that measures the amount of income left over after all variable costs have been paid for. It is calculated by dividing the total contribution margin by total sales revenue and expresses the percentage of each sale that contributes to fixed costs and profits. 

This ratio can be used to evaluate how efficiently companies can generate profits from sales. It can also be used to compare the performance of different business units or products within the same company. The higher the ratio, the more profitable a business is in relation to each sale made. CMR is an important indicator of a company’s profitability and should be monitored regularly by managers and investors. 

With this information, companies can make informed decisions about pricing, production levels, and marketing strategies. The Contribution Margin Ratio is an extremely useful tool for companies to measure their performance and identify opportunities for improvement.

How Can You Calculate Your Contribution Margin Ratio? 

The formula for calculating the contribution margin ratio:

For example, let’s say a company produces products with a total revenue of $800 and variable costs of $300. The contribution margin ratio would be calculated as follows:

Contribution Margin Ratio = ($800 – $300) / $800

            = 0.625 

In this example, the company’s contribution margin ratio is 0.625, which means that 62.5% of their total revenue is left to cover fixed costs and contribute to profits after variable costs are taken into account. 

What factors affect the Contribution Margin Ratio?

The following factors affect the contribution margin ratio:

1. Fixed Costs: 

Fixed costs, such as rent and salaries, do not change with the number of sales or production. When fixed costs are high, the contribution margin ratio will be lower. 

2. Variable Costs:

 Variable costs, such as materials and labor, vary with production or sales volume. When variable costs are high, the contribution margin ratio will be lower.

3. Price: 

The price at which a product is sold can have a large impact on the contribution margin ratio. A higher price allows for a higher contribution margin ratio, while a lower price reduces it. 

4. Product Mix:

 Different products have different cost structures and therefore affect the contribution margin ratio. If a company sells products with low contribution margins, the overall contribution margin ratio will be lower. 

5. Volume: 

The volume of sales or production affects the contribution margin ratio as well. When there is an increase in sales or production, the contribution margin ratio can be improved. 

6. Unit Costs:

 The cost of producing each unit affects the contribution margin ratio. When unit costs are high, the contribution margin ratio will be lower. 

7. Discounts and Promotions:

 Offering discounts or promotions can reduce the price of a product, which in turn lowers the contribution margin ratio. 

8. Operating Efficiency:

 A company’s operating efficiency is affected by its ability to minimize costs while maximizing sales. When operating efficiency is high, the contribution margin ratio will be higher. 

These are just a few of the factors that can affect the contribution margin ratio. It’s important for companies to understand these factors in order to properly manage their operations and achieve desired results.

What is a good Contribution Margin Ratio?

A good Contribution Margin ratio is one that meets your specific business goals. Generally, a higher Contribution Margin ratio means more profit per unit sold, so it can be beneficial to strive for a high ratio. However, a lower Contribution Margin may also work if you need to make large investments upfront in order to produce the product or service. 

Ultimately, the Contribution Margin ratio should be tailored to your business objectives and budget. For example, if you are planning to launch a new product, you may want a higher Contribution Margin in order to cover research and development costs.

On the other hand, if you already have an established product that is selling well, a lower Contribution Margin could still be beneficial if you want to drive more sales volume. Ultimately, the right Contribution Margin ratio can vary widely depending on your goals and resources. It is important to consider all of these factors when determining your optimal target.

What are examples of a Contribution Margin Ratio?

The Contribution Margin (CM) ratio for a company can be calculated by subtracting its cost of goods sold, variable expenses, and any other costs from its total revenue, then dividing the difference by the total revenue. 

For example, if a company has revenues of $50 million, its cost of goods sold is $20 million, marketing costs are $5 million, product delivery fees are $5 million and its fixed costs are $10 million, then its Contribution Margin dollars would be calculated as follows: CM Dollars = $50M –  $20M – $5M – $5M = $20 million.

The Contribution Margin ratio is then found by dividing the CM Dollars by the total revenue: CM Ratio = $20M / $50M = 40%. It is important to note that fixed costs are not included in the formula, however, it must be taken into account to ensure that the CM dollars are greater than the fixed costs, as this will indicate if a company is operating profitably. ​

Example number 2

The Monster company produces and sells two products. Over the past six months, they have incurred total fixed expenses of $60,000, split between 50% manufacturing costs and 50% marketing/administrative expenses. Analysis of the sales and expenditure data reveals which product has a higher contribution margin ratio: there were no beginning or ending inventories.

Product A has a contribution margin ratio of 0.42 (or 42%), whereas Product B has a higher contribution margin ratio of 0.5 (or 50%). This indicates that Product B will be more effective in covering fixed expenses and generating profit compared to Product A.
