How to Read a Profit and Loss (P&L) Statement

A profit and loss (P&L) statement is a financial report that shows whether a business made or lost money over a specific period by comparing total revenue against total expenses. It's different from a balance sheet, which shows what a business owns and owes at a single point in time, and different from a cash flow statement, which tracks the actual movement of cash. If you're staring at your own P&L right now and aren't sure what half the lines mean, this guide walks you through how to read a profit and loss statement the way we would in a client meeting: top to bottom, in the order the numbers actually tell the story.

What a P&L Statement Includes

A P&L statement has four blocks: revenue, cost of goods sold, operating expenses, and net income, in that order. Every P&L follows the same basic sequence: revenue at the top, expenses in the middle, and profit at the bottom.

• Revenue. Everything the business earned from sales.
• Cost of goods sold. The direct cost of producing whatever was sold.
• Operating expenses. The cost of running the business day to day.
• Net income. What's actually left over.

These four blocks build on each other in sequence. Revenue minus cost of goods sold equals gross profit. Gross profit minus operating expenses equals net income.

Some statements add a line or two below operating expenses for interest, taxes, or one-time items. Those sit between operating expenses and net income, and we cover them further down.

Once you know this order, reading any P&L, whether it's this month's or last year's, becomes a matter of finding these four numbers and understanding what sits between them.

Is Revenue the Same as Cash in the Bank?

Not necessarily. On an accrual-basis P&L, revenue is every dollar your business earned from sales during the period, whether or not the customer has paid yet.

Which basis your P&L uses matters here. Under the accrual method, a sale counts the moment it's invoiced or delivered, not the moment the payment clears. Under the cash method, which many small businesses use, revenue lands only when the money arrives. Most platforms can run the report either way, so it's worth confirming which basis yours is set to.

On an accrual basis, a landscaping company that invoices a client $1,000 for a project completed in June records that $1,000 as June revenue, even if the client doesn't actually pay the bill until July. (Under a cash-basis system, that $1,000 would not land on the P&L as revenue until the cash is officially received in July.)

That $1,000 sits as accounts receivable in the meantime, not as a hole in the P&L. If your revenue line looks strong but your bank account doesn't feel that way, the gap usually lives in unpaid invoices, not in a reporting error.

What Counts as COGS on a P&L?

Cost of goods sold, or COGS, is what your business spent directly to produce whatever it sold. Nothing else. For a product-based business, that means materials and the direct labor to manufacture or assemble the product. For a service-based business, it typically means the labor hours billed directly to a client project. Subtracting COGS from revenue gives you gross profit, and dividing gross profit by revenue gives you gross margin, expressed as a percentage.

We see business owners get tripped up on gross profit versus net income more than any other line item on the page, and the mix-up usually starts here. Rent, marketing spend, office software, and administrative salaries are not COGS. Those are operating expenses, and they sit lower on the statement.

If your COGS line includes rent or marketing spend, your gross margin is lying to you: it will look artificially thin, and it will make a genuinely profitable product line look like it's barely breaking even. This is one of the most common corrections we make when we take over bookkeeping from a business owner who's been categorizing expenses on their own.

What Counts as an Operating Expense on a P&L?

Operating expenses are the costs of running the business day to day, everything that keeps the doors open but isn't tied directly to producing what you sold. These sit below gross profit and above net income on the statement. Common examples include:

• Rent and utilities for office or retail space
• Payroll for administrative and management staff
• Marketing and advertising spend
• Software subscriptions and technology costs
• Insurance premiums
• Professional services, including legal and accounting fees

Most of these costs hold steady whether you have a strong month or a slow one, though some, like sales commissions or shipping, do move with volume. Tracking them separately from COGS is what lets you see whether a slow month is a revenue problem or an overhead problem. A business with flat operating expenses and rising revenue should see its margin improve month over month; if it doesn't, the issue usually sits in the COGS line, not here.

What Is Net Income and How Is It Different From Gross Profit?

Net income is what's left after every expense has been subtracted from revenue, the actual profit the business generated. The calculation is straightforward: gross profit minus operating expenses (and, where applicable, minus interest, taxes, or one-time expenses) equals net income. This is the number most people mean when they ask "did we make money this month?"

Gross profit and net income answer two different questions. Gross profit tells you whether the core product or service itself is profitable before overhead is factored in. Net income tells you whether the entire business, overhead included, is profitable. A business can have strong gross margins and still lose money at the net income line if operating expenses have grown faster than revenue. Watching both numbers, not just the bottom line, is how you catch that kind of drift before it becomes a real problem.

What Does a Profit and Loss Statement Example Look Like?

Here's what these terms look like on an actual statement. The figures below are illustrative only, not drawn from any client's real financials:

In this example, gross margin comes out to 60 percent ($72,000 divided by $120,000), which tells you the core business is priced and delivered efficiently. Net margin comes out to 15 percent ($18,000 divided by $120,000), which tells you overhead is eating a meaningful share of that gross profit before it reaches the bottom line. Reading both percentages side by side, not just the dollar figures, is what separates a surface-level glance at a P&L from an actual read of it.
