Fixed cost(s)

The term fixed cost refers to the cost of a business expense that doesn't change even when there's an increase or decrease in the number of goods and services produced or sold. Fixed costs are commonly related to recurring expenses that aren't directly related to production, such as rent, interest payments, and insurance.
Fixed costs are generally indirect in that they are unrelated to a company's production of goods or services. Shutdown points are applied to reduce fixed costs. These costs are among two different types of business—the other being variable costs, which together result in their total costs [Investopedia].
As an example of a fixed cost, the rent on a building will not change until the lease runs out or is re-negotiated, irrespective of the level of activity within that building. Examples of other fixed costs are insurance, depreciation, and property taxes. Fixed costs tend to be incurred regularly, and so are considered to be period costs. The amount charged to expenses tends to change from period to period.
