What is the term for a cost that remains unchanged regardless of production levels or sales revenue?

The term for a cost that remains unchanged regardless of production levels or sales revenue is "Fixed Cost." Fixed costs are expenses that do not fluctuate with production output and are incurred even if a company's output is zero. Common examples include rent, salaries of permanent staff, and depreciation. These costs are essential for businesses to understand because they impact financial planning, budgeting, and pricing strategies.

In contrast, variable costs change directly with the level of production, meaning as production increases, variable costs rise as well. Direct costs are specifically tied to the production of goods, while operating costs encompass both fixed and variable costs associated with running the business. Understanding fixed costs is crucial for businesses as it allows them to set a base level of expenses to cover before they can begin to generate profit.
