Direct materials refer to any materials that are used in the production of a unit that makes it into the product itself. For example, wood is a direct material for the chair company, since the final chair is made of it. Wood is considered a variable cost because the price of it can change over time. The total variable cost for this order of 30 chairs would be $1,500, meaning the chair company’s gross profit for the order would be $900 ($2,400 – $1,500). Variable costs stand in contrast with fixed costs since fixed costs do not change directly based on production volume. It is determined by dividing the cost per unit by the number of units.
It is an aggregation of various variable expenses incurred by a business. Variable costs are expenses that vary in proportion to the volume of goods or services that a business produces. In other words, they are costs that vary depending on the volume of activity. The costs increase as the volume of activities increases and decrease as the volume of activities decreases. As the production output of cakes increases, the bakery’s variable costs also increase. When the bakery does not bake any cake, its variable costs drop to zero.
The higher the percentage of fixed costs, the higher the bar for minimum revenue before the company can meet its break-even point. In contrast, costs of variable nature are generally more difficult to predict, and there is usually more variance between the forecast and actual results. Of course, you don’t want to charge too much and risk losing business to better-priced competition. Using the variable cost formula will help you find the sweet spot between charging too much and too little, ensuring profitability for your business. Notice how the total variable cost goes up according to the number of contracts, much like in the previous example. The longer your production facility is actively operating, the more power and water it’s likely to use.

- For example, if no units are produced, there will be no direct labor cost.
- When the manufacturing line turns on equipment and ramps up production, it begins to consume energy.
- For example, Amy is quite concerned about her bakery as the revenue generated from sales are below the total costs of running the bakery.
- To determine total variable cost, simply multiply the cost per unit with the number of units produced.
Factors Influencing Variable Costs
After calculating variable expenses, it is applied to conduct a break-even analysis of a fed funds rate vs discount rate firm. Thus, when a firm starts a new project, it tries to gauge a ballpark figure of its future expenses. Your goal should be to reduce the cost of producing each item, while maintaining the same level of quality. And that can considerably offset any money you save by cutting costs.
When it’s time to wrap up production and shut everything down, utilities are often no longer consumed. As a company strives to produce more output, it is likely this additional effort will require additional power or energy, resulting in increased variable utility costs. The ingredients required for each cake—flour, sugar, eggs, and icing—are variable costs. If the bakery produces more cakes, it will need more ingredients, causing its variable costs to rise.
Conversely, if the bakery produces fewer cakes, it will require fewer ingredients, and its variable costs will fall accordingly. The steps you take to lower your variable cost per unit and increase your profit margin will depend on what kind of business you run. So, you’re taking variable cost per unit into account, you’re making $10 per mug.
Variable vs Fixed Costs in Decision-Making
A variable cost is any corporate expense that changes along with changes in production volume. As production increases, these costs rise and as production decreases, they fall. Common examples include raw materials, direct labor, and packaging. If companies ramp up production to meet demand, their variable costs will increase as well.
Variable costs, or “variable expenses”, are connected to a company’s production volume, i.e. the relationship between these costs and production output is directly linked. When you calculate your gross margin, net income, and net profit margin, you’ll need to factor your variable and fixed expenses into the formulas. Good variable expense analysis ensures you can calculate how scaling production up or down will impact the company’s bottom line.
If a business increases production or decreases production, rent will stay exactly the same. Although fixed costs can change over a period of time, the change will not be related to production, and as such, fixed costs are viewed as long-term costs. Examples of fixed costs are rent, employee salaries, insurance, and office supplies. A company must still pay its rent for the space it occupies to run its business operations irrespective of the volume of products manufactured and sold.
For instance, airlines have high fixed costs, such as paying for their aircraft. This means they have huge startup costs, but are much less vulnerable to competition once they’re up and running. However, variable costs have limitations, such as their unpredictability during sudden changes and potential neglect of long-term effects. One direct approach to manage variable costs is through negotiations with suppliers. This might mean reducing idle time, optimizing the use of raw materials, or improving production workflows.
Cost-Volume-Profit Analysis
Now that we understand the basics, formula, and how to calculate variable costs equation, let us also explore the practical application through the examples below. Watch this short video to quickly understand the main concepts covered in this guide, including what variable costs are, the common types of variable costs, the formula, and break-even analysis. For this reason, variable costs are a required item for companies trying to determine their break-even point. In addition, variable costs are necessary to determine sale targets for a specific profit target. Commissions are often a percentage of a sale’s proceeds that are awarded to a company as additional compensation.
Determining what constitutes a direct variable cost can sometimes be challenging. Electricity used in a production process might increase with production volume, but it’s hard to attribute a specific amount to each unit produced. For instance, sudden spikes in raw material prices or unforeseen changes in labor costs can significantly impact the variable costs of a business, affecting profitability.
Packaging and Shipping Costs
Factors like production volume, cost per unit, and economies of scale influence variable costs, impacting profitability. Let’s assume that it costs a bakery $15 to make a cake—$5 for raw materials such as sugar, milk, and flour, and $10 for the direct labor involved in making one cake. The table below shows how the variable costs change as the number of cakes baked varies.
The same goes for staffing more hourly wage workers (or having them work more hours) to meet increased production goals. Lastly, variable cost analysis is useful when determining your company’s expense structure. You’ll need variable cost data to make the right decision in this scenario, which will greatly impact profitability and leverage. Note how the total variable cost rises with the number of chairs produced, while the fixed cost remains the same regardless of production output. Variable cost per unit refers to the total cost of producing a single unit of your business’ product.
