Which of the following is NOT typically used in the calculation of gross profit?

Gross profit is calculated using the formula: Gross Profit = Revenue - Cost of Goods Sold (COGS). This means that the relevant components of the formula are specifically revenue and costs directly associated with the production or procurement of the goods sold, which are articulated as COGS.

Operating expenses, which include costs such as salaries, rent, utilities, and other operational costs not directly tied to the product sold, are not subtracted when calculating gross profit. Instead, they are accounted for when determining net profit, which comes after gross profit and accounts for all operating costs.

Therefore, operating expenses are the correct element that does not participate in the calculation of gross profit, making this the right choice. By understanding which components contribute to gross profit, it becomes clearer how businesses assess their profitability directly related to their sales activities.
