Profit and Loss (P&L)

A profit and loss statement — also called an income statement or P&L — is one of the three core financial statements every business needs. It answers the most basic question: did you make money or lose money during this period?

The structure is straightforward. Start with your total revenue (all money earned from sales and services). Subtract the cost of goods sold (COGS) — the direct costs of delivering your product or service. That gives you gross profit. Then subtract all your operating expenses — rent, payroll, marketing, insurance, utilities, software subscriptions, everything it costs to run the business. That gives you operating profit (or loss). Finally, account for interest, taxes, and any unusual items, and you get your net profit (or net loss) — the true bottom line.

A P&L is typically prepared monthly, quarterly, and annually. Monthly P&Ls help you spot trends and problems quickly. Quarterly P&Ls are useful for strategic planning and tax estimates. Annual P&Ls are what your CPA uses for tax preparation and what lenders want to see for loan applications. The P&L is an accrual-based report, meaning it records revenue when earned and expenses when incurred, regardless of when cash actually changes hands.

Your P&L is the scorecard for your business operations. It tells you not just whether you're profitable, but where the money is going. Is your gross margin healthy or are your direct costs too high? Are operating expenses growing faster than revenue? Which expense categories are eating into your profit? Without a regular P&L review, you're guessing. With one, you can make informed decisions about pricing, hiring, cutting costs, or investing in growth. Every CPA, lender, and potential buyer will ask for your P&L first — it's the universal language of business performance.
