How To Calculate Contribution Margin To Increase Revenue

how to calculate contribution margin

It is important to consider how successful the company is when you operate a company. Many managers look at the profit margin, which calculates the gross sales income exceeding costs. So, we will tell you how to calculate contribution margin so that you could understand the contribution of a particular product.
Contribution Margin Definition

The contribution margin is less than the variable cost of a company’s income. The donation dollars arising from this will be used to fund fixed expenses (such as rent), and any surplus is called earnings until it is included. The contribution margin can be seen as the overall sum, the amount per product line, the amount per product, or as the ratio or the percentages of net sales.

The margins are expressed at a percentage or absolute dollars. The contribution margin calculator is calculated with the help of unit variable expense. This metric also shows the overall profit of a company.

How to calculate contribution margin demonstrates the profit potential of an enterprise’s goods and the part of the revenue that helps to offset the firm’s fixed costs. The benefit earned is any residual income after the fixed costs are covered.

Total Contribution Margin Formula

Now let us learn contribution margin calculation. If you look at the financial way your company does, it is tentative to concentrate your attention on the “bottom line.” You turn a profit or not, in other words? If the response is yes, many business owners will stop, hit the back, and vow to do even more. But change is always possible. And you might not continue working the things you do now as the company develops.

One measure to keep an eye on is contribution margin, particularly for companies producing physical goods. To calculate the total contribution margin, we have to see the difference between a product’s purchase price and its manufacturing and sales process variable costs. The contribution margin equation is given as:

Contribution Margin = Net Sales Revenue – Variable Costs


Contribution Margin = Fixed Costs + Net Income

To calculate contribution margin percentage, the equation is given as:

(Net Sales Revenue- Variables Costs)/ (Sales Revenue)

We have learned the formula for contribution margin. Now let us go through the section of fixed cost vs. variable cost.

Fixed Cost Vs. Variable Cost

Fixed Cost Vs. Variable Cost

The one-time cost of goods such as equipment is a common example of the fixed cost, which is unchanged from the number of units sold, although the number of units sold is increasing, and a lower percentage of each unit’s cost. Resources and services that can come at a fixed cost and do not affect the number of units manufactured or distributed are more examples of marginal contribution to risk.

When the government provides unlimited power, for example, at a fixed monthly cost of $100, the production of electricity would cost 10 units or 10,000 units the same fixed cost. The hosting costs remain the same as we have seen in the equation for contribution margin, regardless of whether the customer sets up one or ten websites and whether the customer requires 100MB or 2GB of hosting space.

Such cases shall not include power and web-hosting costs as a fixed cost in the contribution margin formula. However, where the same cost of energy rises in proportion to demand, and the web host charges rise in proportion to the number of sites hosted and the amount of space used, the costs are called variable.

Contribution Margin Example

The fabrication of raw materials is paid for operating a single ink stylus machine and $0.3 is the workload for making the stylus. The variable costs per unit are these three elements in the contribution margin percentage calculator. A sum of $0.2 + $0.1 + $0.3 is the varying cost of production. If 100 inkstones are produced in total the total cost of the variable stones would be ($0.6 * 100 units) = $60, with a total cost of ($0.6 * 10,000 units) = $6,000 for producing 10,000 stones.

But it would not be possible to produce the ink pen without the $10,000 fixed cost manufacturing unit. The estimation of the contribution margin would not take these fixed costs into account. When the overall production costs of a total of 10,000 ink plumb on the unit vary from $6,000 to $10,000, the total production costs would amount to $16,000. The per-unit expense is calculated at 16,000 dollars/10,000 dollars = 1,6 dollars.

A key feature of the contribution margin is that, regardless of the number of units produced or sold, it remains constant on a per-unit basis. On the other hand, with the amount of sold units including the fixed costs, net profit per unit could increase/decrease non-linearly.

In the example above, if the total number of ink styles produced and sold twice as many as 20,000, the total cost (fixed + variable) ($10,000/20,000 + 0,6) = $1,1 per unit. In principle, twice the amount of units sold has raised net profit from 10 000 to 20 000. It offers another dimension for evaluating the amount of income that sales will achieve.

Uses Of Knowing How To Calculate Contribution Margin

The contribution margin will help the management of companies pick the same collection of manufacturing resources from various potential products competing. Tell that a business has a plumbing system that can produce both tin plumbing and ballpoint plumbing, and management must choose only one.

If the contribution margin is greater than the contribution margin for a ball pin, due to its higher profitability potential, the former is preferred to manufacturing. These decisions are common to firms producing a diverse product range and management must make the most effective allocation of resources available to their products.

This type of decision-making is common to businesses that produce a diversified product portfolio, and management needs to assign available capital to goods with the greatest profit potential in the most efficient manner. The contribution margin figure for blockbuster goods of a business can also be calculated by investors and analysts. For example, a drinking business may have 15 goods, but the majority of its profits can originate from one particular drink.

In addition to management, careful investors should track a high-performance product’s contribution margin relative to other goods to determine the company’s reliance on its star performer.

The business which focuses its attention on investing or expanding the production of the star product or on the emergence of the competitive product will show that it can influence the company’s profitability and eventually its share price. Very low or negative margin values of contribution suggest economically unviable goods be discarded for production and sales.

In labor-intensive businesses, such as manufacture, low contribution margin values may be observed as higher variable costs occur, while high contribution margins in capital-intensive sectors are prevalent.

The Contribution Margin principle applies to different production levels, markets, and product segments. For the whole company, a specific subsidiary, an individual division/unit, a specific central/facility, a distribution system or channel, or a product line, or individual goods, the figure can be calculated.

Mistakes People Commit Even After Knowing How To Calculate Contribution Margin

There are many mistakes that people commit even after they know about calculating contribution margin. Some managers are supposed to decrease the lowest margin of contribution items. But the margin of contribution or another indicator of benefit should not be used exclusively; you should also include the assignment of fixed costs. Take the cash cows of a business, a phrase coined by the Boston Consulting Group to describe goods that provide consistent revenue or benefit.

These goods generally need very little support; you don’t have to invest in sales or support research and development. But cash cows usually show a low contribution margin, as they can have high variable costs without drawing on the fixed costs of the business.

But, since you must weigh the cost of supporting a product and how much the business has fixed costs associated with the product, you would not want to reduce the cost. You generally should consider keeping the product around when you notice these goods with a low contribution margin fill a product line or are an obstacle to a competitor’s entry.

Looking at the margin for contribution in a vacuum, you can just be shown. You should also examine other benefit metrics before making any big business decisions.
