Which of the following costs does not change with the level of output?

Fixed costs are expenses that remain constant regardless of the level of production or sales activity within a business. This means that even if a company produces more or fewer units, these costs do not fluctuate. Common examples of fixed costs include rent, salaries of permanent staff, and insurance.

In contrast, variable costs change in direct correlation to the level of output. These costs increase as production increases and decrease when production decreases. Examples include raw materials and hourly wages for temporary workers.

The cash flow statement is a financial document that tracks the cash inflow and outflow of a business, and while it can reflect changes in costs, it is not a type of cost. Break-even refers to the point at which total revenues equal total costs, and does not itself represent a category of cost.

Understanding these differences is essential for effective business management and financial planning. Fixed costs must be accounted for in any cost structure analysis, as they affect profitability even when production levels vary.
