## Contribution Margin Formula + Calculator

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.

Let’s examine how all three approaches convey the same financial performance, although represented somewhat differently. As mentioned above, contribution margin refers to the difference between sales revenue and variable costs of producing goods or services.

We would consider the relevant range to be between one and eight passengers, and the fixed cost in this range would be \$200. If they exceed the initial relevant range, the fixed costs would increase to \$400 for nine to sixteen passengers.

A low contribution margin can signal that a specific product is too expensive and not contributing to a company’s overall profits.

## Examples of Variable Expense Ratios

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.

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

• If they send nine to sixteen students, the fixed cost would be \$400 because they will need two vans.

The answer to this equation shows the total percentage of sales income remaining to cover fixed expenses and profit after covering all variable costs of producing a product. 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.

Product B is contributing more for covering fixed expenses and generating profit because its contribution margin ratio is higher than that of product A. 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.

It may seem reasonable to assume that since ABC has a higher contribution, it is a financially healthier company. The same percentage results regardless of whether total or per unit amounts are used. Here, we are calculating the CM on a per-unit basis, but the same values would be obtained if we had used the total figures instead.

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.

When used on an individual unit sale, the ratio expresses the proportion of profit generated on that specific sale. Using this contribution margin format makes it easy to see the impact of changing sales volume on operating income.
