Fixed Cost

A fixed cost is a business expense that stays the same no matter how many goods or services a company sells. Along with variable costs, it falls under the umbrella of operating expenses, or the money required to operate a business.

While variable costs fluctuate with production or sales volumes, fixed costs do not. Even if a business has no sales to report during a month, it will still be required to pay its fixed costs. Common examples include rent, insurance premiums, and annual registration fees.

How fixed costs work

To calculate fixed costs, add up all costs that stay the same each month. Then, you can calculate the average fixed cost per unit by dividing the number of goods/services produced or sold from the total fixed cost. A financial statement’s fixed costs are usually included in the SG&A section. For example, a business that leases manufacturing equipment pays the same amount each month, whether the equipment runs at full capacity or sits idle. The cost is fixed to the time period, not to output.

Fixed costs can change over time: commercial leases may include annual rent increases at renewal, or an insurance policy may be renegotiated. The term "fixed" describes how the cost behaves within a specific operating period, not that the cost stays the same forever.

Why fixed costs matter

Fixed costs directly affect a business's break-even point, which is the amount of sales needed to cover costs before the business earns a profit. A business with high fixed costs must generate more revenue before it becomes profitable.

Fixed costs also influence pricing decisions. If fixed costs are not fully accounted for, a business may underprice its offerings and operate at a loss even when sales appear strong.

Businesses with lower fixed costs have greater financial flexibility during slow periods, which is especially relevant for small businesses that need to manage cash carefully.

Common examples of fixed costs

A company’s fixed costs differ depending on the industry or type of business, but here are six examples of common fixed expenses:

• Monthly rent or mortgage payments
• Some utilities
• Advertising costs
• Certain salaries
• Depreciation
• Business insurance

Fixed costs vs. variable costs

Variable costs change with production or sales volume. Common examples include raw materials, shipping expenses, and sales commissions. Fixed costs, by contrast, remain the same regardless of output during a given period.

Most businesses carry a mix of both. Understanding the ratio between fixed and variable costs helps owners assess financial risk, set pricing, and evaluate the impact of scaling. A business with mostly fixed costs may benefit more from higher sales volume because each additional sale contributes more to profit after the business covers its fixed obligations.

Fixed costs and business formation

When forming a new business, fixed costs begin accumulating immediately. State filing fees, registered agent fees, and business insurance are among the first fixed costs an LLC or corporation will encounter.

Understanding these costs upfront helps entrepreneurs build realistic financial projections and choose an appropriate business entity status. The ratio of fixed to variable costs helps owners assess financial risk, set prices, and evaluate the impact of scaling.

FAQs about fixed costs

How do you calculate total fixed costs?

Choose a time period, list the expenses that stay the same during that period, and add them together. Common examples include rent, certain salaries, insurance premiums, subscriptions, and recurring service fees. You can also estimate fixed costs by subtracting total variable costs from total costs.

Can a fixed cost become a variable cost?

Yes. A business can change how it pays for a resource. For example, a flat monthly software subscription is a fixed cost, but a usage-based plan may become variable because the cost changes with activity. Some costs can also be mixed, with both fixed and variable parts.

Is labor a variable cost?

Labor may or may not be a variable cost; it depends on the type of labor. Salaries that are based on commission are considered variable because they increase or decrease along with the number of goods or services sold. Administrative salaries, on the other hand, typically would not be considered a variable expense because they stay the same no matter the production or sales volume.
