Which of the following best describes 'cost of goods sold'?

The concept of 'cost of goods sold' (COGS) is essential in understanding a business's profitability. It specifically refers to the direct costs incurred in producing or acquiring the products that a business sells during a specific period. This includes costs such as materials, labor, and overhead that are directly tied to the production or procurement of those goods. Accurate calculation of COGS is important because it directly impacts gross profit—calculated as sales revenue minus COGS—and provides insight into how efficiently a business is managing its production or purchasing processes.

In contrast, the other options describe different aspects of financial performance or operations. Total revenue from merchandise sales refers to the income generated from selling products, without accounting for the costs involved, which means it does not reflect profitability. Overall expenses incurred in running a store include not just the cost of goods sold but also operating costs like rent, utilities, and salaries, making it a broader category that does not specifically define COGS. The profit margin achieved on merchandise is a profitability metric that is derived from revenue and COGS but does not define COGS itself. Thus, identifying COGS accurately is crucial for effective financial analysis and inventory management.
