How are fixed costs defined?

Fixed costs are defined as costs that do not change with the level of production or sales. This means that regardless of how much a company produces or sells, these costs remain constant over a specified period. Examples of fixed costs include rent, salaries, and insurance.

Understanding fixed costs is crucial for businesses because they impact how a company manages its finances and pricing strategies. These costs must be paid even if production is zero, making them a fundamental aspect of financial planning and analysis.

In contrast, other options describe different types of costs. Fluctuating costs relate to variable costs, which increase or decrease with production levels, while variable costs and avoidable costs do not fit the definition of fixed costs. Thus, the correct answer accurately captures the essence of fixed costs in the context of business finance.
