How is a cost that remains constant regardless of output levels classified?

A cost that remains constant regardless of output levels is classified as a fixed cost. This type of cost does not change with the volume of goods or services produced. For example, rent or salaries of permanent staff are considered fixed costs because they must be paid regardless of how much or how little is produced.

In contrast, variable costs fluctuate with production levels, increasing when output rises and decreasing when production falls. Marginal cost refers to the cost added by producing one additional unit, and average cost is calculated by dividing total costs by the number of units produced. Therefore, fixed costs are distinct in that they are stable and do not vary with production output, making them crucial for businesses in budgeting and forecasting.
