What is the term for a detailed breakdown of the costs associated with a product or service?

The term that accurately describes a detailed breakdown of the costs associated with a product or service is "cost structure." Cost structure refers to the various types of costs that a business incurs while creating its products or services. This includes fixed and variable costs, production costs, and other expenses that contribute to the overall cost of delivering a product or service. Understanding the cost structure is vital for effective pricing, analysis of profitability, and strategic financial planning.

While cost analysis involves examining the costs and revenues of a given project, providing insights related to efficiencies and potential cost savings, it is a broader evaluation rather than a breakdown. An expense report is typically a document submitted to account for costs incurred by individuals or departments, detailing specific transactions rather than the overall structure of costs pertaining to a product or service. A budget overview offers a summary of expected revenues and expenditures over a specific period but does not provide the detailed breakdown inherent in a cost structure. Thus, "cost structure" stands out as the most precise term in this context.
