Examples of Variable Costs


A crucial aspect of understanding business expenses is differentiating between fixed costs and variable costs. While fixed costs remain constant regardless of production or sales volume, variable costs fluctuate based on various factors. Variable costs play a significant role in determining a company’s profitability and decision-making process. In this article, we will explore examples of variable costs across different industries and provide insight into how they impact business operations.

1. Direct Labor

Direct labor represents the wages paid to employees directly involved in the production process. As production volume increases or decreases, the labor required changes, resulting in variable costs. For instance, a manufacturing company may need to hire additional workers during peak production periods to meet demand, leading to increased labor costs. Conversely, during slower periods, the company may reduce its labor force, reducing variable costs.

2. Raw Materials

Raw materials are essential components used in the production of goods. Depending on production needs, the amount of raw materials required varies, directly impacting costs. For example, a bakery’s variable costs for flour, sugar, and other ingredients fluctuate based on the number of baked goods produced. If the bakery experiences an increase in demand, it will need to purchase more raw materials, leading to higher variable costs.

3. Energy Consumption

Energy consumption represents a significant variable cost for many businesses. Companies that rely heavily on machinery and equipment, such as manufacturing plants or data centers, often experience varying energy needs. This can be influenced by factors like production output, seasonal variations, or changes in operating hours. Consequently, businesses may see fluctuations in their energy bills, making energy consumption a variable cost.

4. Packaging and Shipping

Companies that produce and distribute physical products incur variable costs associated with packaging and shipping. As the volume of goods sold changes, packaging materials and shipping expenses increase or decrease accordingly. For instance, an e-commerce retailer shipping more products during holiday seasons will experience higher variable costs due to increased packaging and shipping requirements.

5. Sales Commissions

Sales commissions are variable costs associated with compensating sales representatives based on their performance. As salespeople generate more revenue, their commissions increase. Conversely, during periods of low sales, commissions decrease. This incentivizes sales efforts and allows businesses to align costs with actual sales volume.

6. Advertising and Marketing

Advertising and marketing expenses can vary based on a company’s promotional activities. For instance, businesses may invest in television advertisements, digital marketing campaigns, or social media promotions to increase brand awareness and drive sales. These costs fluctuate depending on the intensity and scope of marketing efforts, making them variable costs.

7. Equipment Maintenance

Maintaining machinery and equipment is crucial for businesses operating in industries such as manufacturing, construction, or transportation. The frequency and extent of equipment maintenance depend on various factors, including usage, age, and environmental conditions. As maintenance needs fluctuate, businesses experience variable costs associated with servicing and repairing their equipment.

8. Research and Development

Research and development (R&D) costs are often variable, especially in industries driven by innovation. Companies that invest in developing new products or improving existing ones face fluctuating R&D expenses. Depending on the projects undertaken, businesses may need to allocate varying resources to research, prototyping, and testing, resulting in variable costs.

9. Inventory Holding Costs

Inventory holding costs are variable expenses incurred while storing and managing inventory. These costs include warehousing, insurance, depreciation, and obsolescence. As companies carry more inventory, these variable costs increase. Conversely, businesses with lower inventory levels experience reduced holding costs.

10. Outsourced Services

Businesses often rely on outsourced services for various functions, ranging from IT support to payroll processing. The costs of outsourced services can vary based on usage or the specific terms of service agreements. For instance, a company utilizing outsourced customer support might see variable costs tied to the number of customer inquiries handled by the service provider.

11. Training and Development

Training and development costs can fluctuate depending on a company’s workforce needs. When hiring new employees or promoting internal staff, businesses incur training expenses to equip individuals with necessary skills. The level of training required may vary, contributing to variable costs. For example, a company rapidly expanding its workforce will likely have higher training and development expenses.

12. Legal and Professional Fees

Legal and professional fees represent variable costs for businesses in various situations. Companies seeking legal advice or using professional services, such as accounting or consulting, may experience fluctuations in costs. The complexity and scale of specific projects or legal matters can influence the variable nature of these expenses.

13. Freight and Delivery Costs

Freight and delivery costs impact companies involved in transporting goods. These costs depend primarily on the distance, weight, and mode of transportation used. Factors such as fuel prices and carrier rates can also contribute to variable costs. Businesses with higher shipping requirements or complex supply chains often experience fluctuations in freight and delivery expenses.

14. Product Returns and Refunds

Product returns and refunds result in variable costs for businesses that offer warranties or have customer-friendly return policies. The volume of returned products and the associated costs of restocking, refurbishing, or replacing items directly impact overall expenses. These variable costs can increase if customers frequently return or exchange products.

15. Utilities

Utilities encompass various services required for daily business operations, including water, gas, heating, and internet. Depending on factors like seasonality, company size, or specific usage, utility expenses can fluctuate. For instance, retail businesses may experience higher utility costs during peak seasons due to increased heating or cooling demands.


Understanding variable costs is essential for effectively managing and forecasting expenses within a business. By recognizing the examples of variable costs, companies can make informed decisions to optimize their operations, improve profitability, and mitigate risks. Monitoring, analyzing, and adjusting variable costs become critical for maintaining financial stability and sustainable growth in today’s dynamic business environment.


1. What is the difference between fixed costs and variable costs?

Fixed costs remain constant regardless of production or sales volume, while variable costs fluctuate based on various factors, such as production levels, sales volume, or usage.

2. Why are variable costs important for businesses?

Variable costs directly impact a company’s profitability and decision-making process. Managing and analyzing variable costs allows businesses to adjust their expenses based on changing circumstances, optimizing operations and improving financial outcomes.

3. Can variable costs be controlled or reduced?

While certain factors influencing variable costs, such as external market forces, may be beyond a business’s control, companies can implement strategies to manage and reduce variable costs. This can include optimizing production processes, negotiating supplier contracts, or improving energy efficiency.

4. How do businesses determine variable costs?

Determining variable costs requires analyzing expenses that fluctuate with changes in production, sales volume, or usage. Tracking historical data, conducting cost-volume-profit analysis, and engaging in regular financial analysis can help businesses understand and forecast variable costs.

5. Are all costs that fluctuate considered variable costs?

No, not all costs that fluctuate are considered variable costs. Some expenses may exhibit variations but still remain fixed, such as rent or salaries for permanent employees. Variable costs specifically pertain to expenses directly influenced by changes in production or sales volume.
