Period Costs
Overview of Period Costs
Definition of
Period Costs

What are Period Costs? Period Costs are all expenses that are not included in product costs (i.e., not directly tied to the manufacturing or acquisition of goods for sale). Instead, period costs are expensed on the income statement in the specific period in which they are incurred. They are typically associated with the passage of time rather than the production process itself. Common examples include selling expenses (like sales salaries, advertising) and general & administrative (SG&A) expenses (like office rent, administrative staff salaries, utilities for the office).

The Importance of
Period Costs
For small business owners, understanding Period Costs is essential for accurate financial reporting and profitability analysis. Since these costs are expensed in the period they happen, they directly affect the calculation of net profit on the income statement for that specific period. Distinguishing period costs from product costs (which are capitalized as inventory and expensed as COGS when sold) is crucial for correct inventory valuation and income measurement according to accrual accounting principles. Proper classification helps in effective expense tracking and control.

Not Product-Related
Period costs are not directly associated with the production or acquisition of goods intended for sale; they relate to general business operations.
Expensed When Incurred

Typically SG&A
