Is rental revenue a product cost or period cost?

Rental revenue is typically considered a period cost, as it is associated with the cost of occupying a space over a specific time period rather than being directly tied to the production of goods or services. Period costs are expensed in the period they are incurred, unlike product costs, which are capitalized as inventory until sold. Therefore, rental revenue does not fall under product costs but rather aligns with expenses recognized in the income statement for that period.
