The Profit and Loss statement — also called the P&L or income statement — is the financial report that tells you whether your business is actually making money. Many small business owners avoid looking at their P&L because it feels intimidating. In reality, once you understand its structure, it’s one of the most useful tools you have for making smart business decisions.
What Is a P&L Statement?
A Profit and Loss statement summarizes your business’s revenues, costs, and expenses over a specific time period — typically a month, quarter, or year. At the most basic level, it answers one question: Did you make money or lose money during this period?
Understanding your P&L empowers you to spot trends, identify where money is being lost, evaluate the impact of pricing decisions, and make informed choices about where to invest or cut back.
The Basic Structure
Every P&L follows the same fundamental structure, working from the top down:
Revenue (or Sales)
This is the total money your business earned from selling products or services before any expenses are deducted. Also called the “top line,” revenue is the starting point of every P&L.
Cost of Goods Sold (COGS)
These are the direct costs of producing your products or delivering your services — materials, direct labor, shipping, manufacturing. For a service business, COGS might include contractor costs or supplies used directly in delivering the service.
Gross Profit
Revenue minus COGS equals gross profit. This tells you how much money you’re making before accounting for operating expenses. Gross profit margin (gross profit divided by revenue, expressed as a percentage) is one of the most important metrics in your business.

Operating Expenses
These are the costs of running the business that aren’t directly tied to production — rent, utilities, insurance, marketing, salaries, software subscriptions, and professional services. Operating expenses are sometimes divided into selling expenses and general and administrative expenses.
Operating Income (EBIT)
Gross profit minus operating expenses equals operating income — also called Earnings Before Interest and Taxes (EBIT). This is what your business earned purely from operations, before accounting for financing costs and taxes.
Net Income (The Bottom Line)
After subtracting interest expenses, taxes, and any other non-operating costs, you’re left with net income — the famous “bottom line.” This is what your business actually kept after all expenses.
What to Look For When Reading Your P&L
Revenue trend: Is it growing, flat, or declining compared to previous periods?
Gross margin: Is it consistent or shrinking? Declining gross margins indicate that your costs of delivery are rising faster than your prices.
Expense ratios: What percentage of revenue goes to each expense category? Are any categories growing disproportionately?
Net profit margin: What percentage of every dollar of revenue ultimately becomes profit?

Common P&L Mistakes Small Business Owners Make
- Looking at revenue alone and ignoring margins
- Not reviewing the P&L regularly (monthly is ideal)
- Mixing personal expenses with business expenses
- Misclassifying costs (putting COGS in operating expenses distorts your margins)
- Not comparing to prior periods (a single snapshot has limited meaning without context)
Making Your P&L Work For You
Review your P&L every month, even if it’s uncomfortable. The discomfort usually signals something you need to address. Compare current month to prior month, and current month to the same month last year.
Use what you find to ask better questions: Why did gross margin drop this month? What’s driving the increase in operating expenses? Is revenue growth translating into proportional profit growth?
