Explanation:

Fixed costs consist of business expenses that remain constant throughout a financial period. The level of production does not influence these costs. Fixed costs are sometimes considered as the cost of staying in business. They have to be paid as long as the business is open.

For instance, administrative salaries have to be paid regardless of the level of production. Monthly rent to a store has to be paid even if no sales were made in a particular month. Other examples of fixed costs include depreciation, insurance premiums, and advertising.
