8 20: Contribution Margin Ratio Business LibreTexts

The contribution margin ratio is used by finance professionals to analyze a company’s profitability. It is often used for building a break-even analysis, which helps companies determine at what point a new business project will reach enough sales to cover the costs. However, ink pen production will be impossible without the manufacturing machine which comes at a fixed cost of $10,000. This cost of the machine represents a fixed cost (and not a variable cost) as its charges do not increase based on the units produced. Such fixed costs are not considered in the contribution margin calculations. The contribution margin is computed as the selling price per unit, minus the variable cost per unit.

Contribution margin vs. gross margin

As production levels increase, so do variable costs and vise versa. However, this implies that a company has zero variable costs, which is not realistic for most industries. As such, companies should aim to have the highest contribution margin ratio possible, as this gives them a higher likelihood of covering its fixed costs with the money remaining to reach profitability.

How is contribution margin calculated?

• The contribution margin ratio refers to the difference between your sales and variable expenses expressed as a percentage.
• You can see how much costs can affect profits for a company, and why it is important to keep costs low.
• Now, it is essential to divide the cost of manufacturing your products between fixed and variable costs.
• Thus, to arrive at the net sales of your business, you need to use the following formula.
• Looking at contribution margin in total allows managers to evaluate whether a particular product is profitable and how the sales revenue from that product contributes to the overall profitability of the company.

Contribution margin ratio is a calculation of how much revenue your business generates from selling its products or services, once the variable costs involved in producing and delivering them are paid. This can be a valuable tool for understanding how to price your products to ensure your business can pay its fixed costs, such as salaries and office rent, and still generate a profit. The break even point (BEP) is the number of units at which total revenue (selling price per unit) equals total cost (fixed costs + variable cost).

If the selling price per unit is more than the variable cost, it will be a profitable venture otherwise it will result in loss. All you have to do is multiply both the selling price per unit and the variable costs per unit by the number of units you sell, and then subtract the total variable costs from the total selling revenue. Let’s examine how all three approaches convey the same financial performance, although represented somewhat differently.

Formula to Calculate Contribution Margin Ratio

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

As mentioned above, the per unit variable cost decreases with the increase in the level of production. Sales revenue refers to the total income your business generates as a result of selling goods or services. Furthermore, sales revenue can be categorized into gross and net sales revenue. 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 general, the higher the contribution margin ratio, the better, with negative numbers indicating a loss on every unit produced. This demonstrates that, for every Cardinal model they sell, they will have $60 to contribute toward covering fixed costs and, if there is any left, toward profit. Every product that a company manufactures or every service a company provides will have a unique contribution margin per unit. In these examples, the contribution margin per unit was calculated in dollars per unit, but another way to calculate contribution margin is as a ratio (percentage).

You can use the contribution margin calculator using either actual units sold or the projected units to be sold. This means Dobson books company would either have to reduce its fixed expenses by $30,000. On the other hand, net sales revenue refers to the total receipts from the sale of goods and services after deducting sales return and allowances. As you can see, the net profit has increased from $1.50 to $6.50 when the packets sold increased from 1000 to 2000. However, the contribution margin for selling 2000 packets of whole wheat bread would be as follows. Thus, you need to make sure that the contribution margin covers your fixed cost and the target income you want to achieve.

In other words, your contribution margin increases with the sale of each of your products. Remember, that the contribution margin remains unchanged on a per-unit basis. Whereas, your net profit may change with the change in the level of output.

Any remaining revenue left after covering fixed costs is the profit generated. For variable costs, the company pays $4 to manufacture each unit and $2 labor per unit. That said, most businesses operate with contribution margin ratios well below 100%. The difference between the selling price and variable cost is a contribution, which may also be known as gross margin.
