Which type of cost remains unchanged regardless of the level of goods or services produced?

Fixed costs are expenses that do not fluctuate with the level of production or sales. This means that whether a business produces one unit or thousands of units, the total fixed costs remain constant. Examples of fixed costs include rent, salaries of permanent staff, and insurance premiums. These costs are incurred regardless of the output level, making them a crucial aspect of financial planning and budgeting for businesses.

In contrast, variable costs change according to the level of production; as more goods are produced, variable costs increase. Direct costs are linked directly to the production of goods, whereas marginal costs refer to the cost of producing one additional unit. Understanding fixed costs is key to analyzing a business's overall financial health since they impact profitability depending on the volume of production and sales.
