Fixed Costs: Business Expenses That Stay the Same Regardless of Output

In business and economics, fixed costs are the expenses that do not change with the level of production or sales.
Whether a company produces one unit or a thousand, these costs remain constant over a given period.

In simple terms, fixed costs are the bills a business must pay no matter how much it produces.

Core Idea

Fixed costs represent the baseline expenses a company must cover to operate, regardless of how much it sells or manufactures.
They differ from variable costs, which rise or fall depending on output (like raw materials or shipping costs).

Because fixed costs remain steady, they are a key factor in determining a company’s break-even point — the level of sales needed to cover all expenses.

In Simple Terms

Fixed costs are the everyday running costs that don’t depend on how busy a company is.
Even if no products are sold, the company still needs to pay for rent, insurance, and salaries.

Example

A small manufacturing business pays the following monthly expenses:

Factory rent: $5,000

Salaries for permanent staff: $10,000

Equipment depreciation: $2,000

Insurance: $500

These costs total $17,500 per month, and they must be paid whether the factory produces 10 or 10,000 units.
However, costs for raw materials or packaging — which change with production volume — are variable costs, not fixed.

Real-Life Application

Fixed costs are important for budgeting, pricing, and profit planning.
Businesses use them to:

Calculate the break-even point (where total revenue equals total costs).

Decide whether to scale production up or down.

Measure operating leverage, or how profits change when sales fluctuate.

A company with high fixed costs (like an airline or factory) must maintain a higher sales volume to stay profitable, while one with low fixed costs (like an online service) can adjust more easily to demand changes.

Common Misconceptions and Mistakes

“Fixed costs never change.” They can change over time due to rent increases, new contracts, or inflation — but they don’t fluctuate with output in the short term.

“Salaries are always fixed.” Some salaries (like sales commissions) vary with performance and are therefore variable costs.

“All overheads are fixed.” Many overheads include both fixed and variable components.

“Fixed costs are bad.” Not necessarily — they can provide stability and predictability, especially for long-term planning.

Summary

Fixed costs are expenses that remain constant regardless of production or sales levels, such as rent, salaries, and insurance.
They form the foundation of a company’s cost structure and are crucial for understanding profitability, break-even analysis, and financial stability.
While predictable, high fixed costs can increase business risk if sales decline.
