Hayes, A. (2025, February 27). Cost accounting explained: Definitions, types, and practical examples. Investopedia. https://www.investopedia.com/terms/c/cost-accounting.asp

Hayes offers a thorough explanation of cost accounting, a branch of accounting focused on capturing a company's total cost of production by assessing both fixed and variable expenses. The article contrasts cost accounting with financial accounting, noting that the former is primarily an internal tool used for budgeting and price setting. Hayes details several key cost accounting methodologies, including standard costing, activity-based costing (ABC), lean accounting, and marginal costing. Each method is evaluated for its specific utility in different business contexts, such as manufacturing or service industries. The text also provides practical examples of how cost data helps managers identify where a company is losing money and how to improve profit margins. This resource is particularly valuable for understanding the granular level at which expenses are tracked to optimize the financial performance of specific products, processes, or departments.
