Which of the following is considered a fixed cost?

Rent for factory space is considered a fixed cost because it remains constant regardless of the level of production or sales volume. Fixed costs are expenses that do not change with the quantity of goods or services produced and must be paid regardless of business activity. In the case of rent, the payment amount is predetermined and does not vary month to month based on output.

In contrast, raw materials used in production and employee overtime wages are variable costs that fluctuate based on the level of production and operations. Similarly, utility costs are often variable; they typically vary with usage, meaning they can increase or decrease depending on how much energy or water is consumed, and thus are not fixed.
