Frequently Asked Questions
Clear answers on profit and loss statements, operating margins, COGS vs. OPEX, and business tax calculations.
An Income Statement—commonly called a Profit and Loss (P&L) statement—is a financial summary showing how much money your business earned and spent over a specific window of time, such as a month, quarter, or full year. It starts with your total sales (Gross Revenue), subtracts your direct production expenses and operating overhead, and ends at your bottom line: Net Operating Income. If revenue is higher than total expenses, you made a net profit; if expenses exceed sales, you ran at a net loss.
An income statement behaves like a video recording of your cash flow over a duration of time, while a balance sheet is a single snapshot taken on a specific calendar date. Your P&L tracks the incoming revenue and outgoing expenses accumulated between the first and last day of the month. In contrast, your balance sheet reveals what your company owns (assets) and owes (liabilities) at one frozen moment in time, proving your business's overall net worth.
Across most commercial industries, a 10% net profit margin is considered healthy, while a margin of 20% or higher represents strong financial performance. Acceptable margins vary significantly by business model: low-overhead service firms, freelancers, and software-as-a-service (SaaS) businesses frequently achieve 30% to 50% net margins, whereas physical retail stores, restaurants, and inventory-heavy e-commerce brands often operate between 3% and 8% due to high supplier and shipping costs.
Cost of Goods Sold (COGS) covers direct expenses tied directly to producing or delivering your product, such as raw materials, wholesale inventory, manufacturing labor, and packaging. Operating Expenses (OPEX) cover the everyday overhead required to run your company regardless of sales volume, including office rent, accounting software, team payroll, internet access, and marketing campaigns. Separating the two helps you pinpoint whether pricing issues stem from production costs or high overhead.
It depends on your business entity structure. For sole proprietorships, single-member LLCs, and general partnerships, owner draws or distributions are not considered operating expenses on a P&L; they are equity withdrawals taken from the company's net profits. However, if your business is structured as an S-Corporation or C-Corporation and you receive formal W-2 payroll salary with payroll taxes withheld, that specific salary is reported as a valid operating expense under personnel costs.
