what is a variable cost

In contrast, costs of variable nature are generally more difficult to predict, and there is usually more variance between the forecast and actual results. The amount incurred is directly tied to sales performance and customer demand, which are variables that can be impacted by “random” factors (e.g. market trends, competitors, customer spending patterns). For instance, let’s say you make and sell hand-painted “World’s Best Boss” mugs. Material substitution, when done right, can be a strategic move to manage variable costs effectively.

High operating leverage can benefit companies since more profits are obtained from each incremental dollar of revenue generated beyond the break-even point. Thus, which costs are classified as variable and which as fixed depends on the time horizon, most simply classified into short run and long run, but really with an entire range of time horizons. An example of an indirect material would be sandpaper, which is necessary for creating the chairs, but doesn’t make it into the final product.

  1. In this case, suppose Company ABC has a fixed cost of $10,000 per month to rent the machine it uses to produce mugs.
  2. Since variable costs are tied to output, lower production volume means fewer costs are incurred, which eases the cost pressure on a company — but fixed costs must still be paid regardless.
  3. If companies ramp up production to meet demand, their variable costs will increase as well.

Are Variable Costs unit-based?

If the total variable expenses incurred were $100,000, the variable cost per unit is $100.00 per hour. If product demand (and the coinciding production volume) exceed expectations — in response, the company’s variable costs would adjust in tandem. Variable costs are directly tied to a company’s production output, so the costs incurred fluctuate based on sales performance (and volume). But even if it produces one million mugs, its fixed cost remains the same.

Understanding these factors can help businesses strategize better and maintain optimal operations. Fixed costs are normally independent of a company’s specific business activities. Variable costs increase as production rises and decrease as production falls. Understanding the difference between these costs can help a company ensure its fiscal solvency. One of the essential limitations of variable costing is that it does not comply with Generally Accepted Accounting Principles (GAAP) for external financial reporting or financial statements.

Examples of variable costs are sales commissions, direct labor costs, cost of raw materials used in production, and utility costs. Unlike fixed costs, these types of costs fluctuate depending on the production output (i.e. the volume) in a given period. Since costs of variable nature are output-dependent, the costs incurred increase (or decrease) given varying production volumes. Calculating variable costs can be done by multiplying the quantity of output by the variable cost per unit of output. Costs that vary directly in response to shifts in production or sales levels are known as variable costs.

These costs have a mix of costs tied to each unit of production and a fixed cost which will be incurred regardless of production volume. For instance, purchasing raw materials in bulk might result in discounts, thereby reducing the cost per unit. Similarly, streamlining production processes can also lead to decreased costs per item. Alternatively, advancements in technology or improved procurement strategies might lower the cost per unit, resulting in reduced variable costs.

In this guide, we’ll break down everything you need to know about variable costs. A variable cost is a type of corporate expense that changes depending on how much (or how little) your company produces or sells. Depending on how your sales or production rates are going, your variable costs can rise or fall—hence the name.

A member of the CPA Association of BC, she also holds a Master’s Degree in Business Administration from Simon Fraser University.

Essentially, if a cost varies depending on the volume of activity, it is a variable cost.

Regularly monitoring and adjusting to these shifts is crucial for maintaining profitability. For example, Amy is quite concerned about her bakery as the revenue generated from sales are below the total costs of running the bakery. Amy asks for your opinion on whether she should close down the business or not.

The longer your production facility is actively operating, the more power and water it’s likely to use. Utilities are a variable cost because they usually increase and decrease alongside your production. If your company accepts credit card payments from customers, you’ll have to pay transaction fees on each sale. This is a variable cost since it depends on how many sales you make (and what methods your customers use to pay). For instance, airlines have high fixed costs, such as paying for their aircraft.

Since a company’s total costs (TC) equals the sum of its variable (VC) and fixed costs (FC), the simplest formula for calculating a company’s variable costs is as follows. Marginal costs can include variable costs because they are part of the production process and expense. Variable costs change based on the level of production, which means there is also a marginal cost in the total cost of production. The contribution margin represents the sum of income that remains after covering variable costs. It is calculated by subtracting the total variable costs from total sales revenue. Once you have the VCU, you can calculate the total variable costs for various production or activity levels by multiplying it by the number of units.

This can fluctuate based on various factors such as the price of raw materials or changes in labor costs. 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. 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.

Your goal should be to reduce the cost of producing each item, while maintaining the same level of quality. To figure out variable costs for your product, you’ll need to do a little math. If the differences between the two still seem unclear, you should get a better sense of them with the examples of fixed vs. variable expenses below. Notice how the total variable cost goes up according to the number of contracts, much like in the previous example.

This may be particularly important in businesses with fluctuating production volumes or complex product lines. If you pay based on billable hours, commissions, or piece-rate labor rates (when workers are paid based on how many units they produce), these would be considered variable costs. The same goes for staffing more hourly wage workers (or having them work more hours) to meet increased production goals. Factors like production volume, cost per unit, and economies of scale influence variable costs, impacting profitability.

If you’re having trouble seeing how these techniques could apply to your business, consider hiring a business operations or managerial accounting consultant with experience in your industry. They may be able to find loopholes, shortcuts, and tricks of the trade that can help you reduce your variable costs. So, you’re taking variable cost per unit into account, you’re making $10 per mug. To calculate the variable cost of each item you sell, add up every expense directly related to creating it—the variable cost per unit. To better explain this concept and differentiate variable and fixed costs, we’ll use a few examples to help you understand how they may apply to your industry. In this example, the average variable cost formula simply works backward to arrive at our original cost per unit.

The facility and equipment are fixed costs, incurred regardless of whether even one shirt is made. An example of a variable cost per unit would be if a company makes chairs. Each chair costs $25 in direct labor and $25 in direct materials to produce. This would mean the total variable cost per unit of a single chair would be $50.
