Contribution margin

Contribution margin

Knowing your company’s profitability is crucial while running one. Many business executives consider their profit margin, representing the overall margin by which sales income surpasses costs.  

But it would be best to look at the contribution margin to see how a product affects the company’s earnings. The incremental profit made on each sold unit of a product is represented by the contribution margin, which is the revenue from a product less the direct variable costs. 

What is contribution margin? 

The contribution margin describes how a rise in sales may impact a rise in profits. The margin is calculated by deducting variable costs from sales income; the remaining sum pays for fixed expenditures. Profit or earnings are any revenue that remains after fixed expenses. 

Depending on the calculation, a company’s contribution margin may be shown as a dollar figure or a ratio. The algorithm can examine margins for the entire business, particular product lines, or individual product units. Companies and investors use a variety of indicators to help them make data-driven decisions about their businesses. Contribution margins should not be seen in isolation, as with other numbers, but rather in the context of other indicators. 

Understanding contribution margin 

The contribution margin is usually used as a point of comparison for analysis when a business decides on the pricing of a product. As fixed costs are frequently substantial, a company’s contribution margin must be significant to meet its operating expenses.  

If a product line or business has a low or negative contribution margin, it may not be wise to continue producing it at the current sales price level unless it is a very high-volume item.  

Investors evaluate contribution margins to assess how efficiently a firm uses its revenues. An organisation is more likely to generate revenue than expenses if its contribution margin is large. 

Economically non-viable items whose production and sales consume a significant percentage of the revenues are those with extremely moderate or negative contribution margin values. 

At many production stages, business sectors, and product levels, contribution margin is a relevant concept. An entire company, a specific subsidiary, a corporate division or unit, a specific centre or facility, a specific channel for distribution or sales, a specific product line, or a specific product can all have their respective figures computed. 

Formula of contribution margin 

The following is the key formula for calculating contribution margins: 

Contribution margin = Net sales – total variable costs 

Where, 

• Net sales or revenue is a business’s money from selling goods or services. 

• Variable costs are manufacturing costs for goods or services that change according to labour, suppliers, and production volume. 

The formula for calculating the contribution margin ratio is:  

Contribution Margin Ratio = (net sales – total variable costs) / net sales 

The formula for calculating contribution margins can also be expressed as: 

Contribution margin = fixed costs – net income 

Where, 

• Fixed costs don’t change regardless of how the manufacturing process flows; even if production stops for a few weeks, the corporation still has to cover these costs. 
• Sales revenue is calculated after taking away the cost of products sold, operating expenditures (such as rent, marketing, and advertising), interest costs, and taxes. This gives you net income. 

Calculation of contribution margin 

Let’s use an example where an online retailer sells toys for US$ 25.00 with variable costs of US$ 10.00 for each item. The price of a toy is US$ 25. The variable cost per unit is US$ 10. 

The contribution margin would be determined using the following formula: 

Margin = US$ 25.00 – US$ 10.00 = US$ 15.00. 

The following formula is used to get the contribution margin ratio: 

Contribution margin ratio = US$ 15.00 / US$ 25.00 = 0.60, or 60% 

With a 60% ratio, the contribution margin is US$ 0.60 for every dollar of revenue earned.
