How to read a profit and loss statement

A profit and loss statement, often called a P&L or an income statement, shows how much your business earned, how much it spent, and what was left over during a period of time. That period is usually a month, a quarter, or a year. It is one of the most useful reports a small-business owner can read, and it is less complicated than it looks. This guide walks through each part in plain language.

The main parts of a profit and loss statement

Most P&Ls follow the same order, from top to bottom.

Revenue

Revenue, also called sales or income, is the money your business earned from selling products or services during the period. It is the top line of the report. Depending on how your books are kept, it may include sales you billed but have not been paid for yet, or only the money you actually received.

Cost of goods sold

Cost of goods sold, often shortened to COGS, is the direct cost of what you sold. For a business that sells products, it includes things like inventory and materials. For some service businesses, it can include direct labor or subcontractors tied to specific jobs. Not every business has this section.

Gross profit

Gross profit is revenue minus cost of goods sold. It tells you how much is left from your sales after paying for what went directly into them. That money is what pays for everything else in the business.

Operating expenses

Operating expenses are the costs of running the business that are not tied to one specific sale. Rent, software, insurance, phone, advertising, office supplies, and many payroll costs usually belong here. On a well-kept P&L, these are grouped into clear categories so you can see where the money goes.

Net income

Net income is what remains after all expenses are subtracted from revenue. It is the bottom line. A positive number is a profit for the period. A negative number is a loss.

A simple example

Here is a short example. These are example figures, not a real client.

Say a business had $24,500 in revenue for the month. Its total expenses for the month, including cost of goods sold and operating expenses, were $17,250. Net income for the month is $24,500 minus $17,250, which is $7,250.

That one number already says something useful: the business kept a little under 30 cents of every dollar it brought in that month. But the more helpful questions come from looking at the parts. Which expenses make up the $17,250? Did any of them grow faster than sales? Is $7,250 typical, or was this an unusual month?

What to look for month over month

One P&L is a snapshot. Comparing several months side by side shows the story. A few things are worth watching:

Revenue trends. Is revenue growing, flat, or seasonal? Are certain months always slower?
Gross profit. If revenue goes up but gross profit does not keep pace, your direct costs may be rising.
Expense categories that jump. A category that suddenly doubles is worth a question. Sometimes it is a one-time purchase. Sometimes it is a cost that has been creeping up.
Net income over time. One weak month is normal. A steady downward trend deserves a closer look.
Anything that looks off. An empty category or a strange number can be a sign that a transaction was recorded in the wrong place.

Questions a P&L helps you ask

The real value of a P&L is the conversation it starts. Reading it each month can help you ask questions like these:

Are my prices covering my costs?
Which expenses could I reduce, and which ones help the business grow?
Can I afford to hire, buy equipment, or take on a new project?
Am I setting aside enough for taxes, based on what the business is earning?
Was this month normal, or did something change?

Keep in mind that profit is not the same as cash in the bank. A P&L can show a profit while cash feels tight, for example when customers have not paid yet or when you made a loan payment. That is one reason it helps to look at your reports with someone who can explain them.

A P&L is only as good as the books behind it

A profit and loss statement is built from your bookkeeping. If transactions are missing, miscategorized, or months behind, the report will not reflect what really happened. Regular, organized bookkeeping is what makes the P&L something you can trust and use.

With our monthly bookkeeping, we keep your books organized, prepare regular financial reports, and help you understand what the numbers mean for your business. Monthly bookkeeping starts at $200 per month, and the QuickBooks subscription is separate.

Questions about this topic

Is a profit and loss statement the same as an income statement?

Yes. They are two names for the same report, and many people also call it a P&L. It shows revenue, expenses, and net income for a period of time.

Why does my P&L show a profit when I don't have much cash?

Profit and cash are measured differently. Unpaid customer invoices, loan payments, inventory purchases, and money you take out of the business can all affect your cash without matching the profit on the P&L. Looking at the P&L together with your balance sheet and bank activity gives a fuller picture.

How often should I look at my profit and loss statement?

Monthly is a good habit for most small businesses. It lets you spot changes early and compare one month with another while the details are still fresh.

Can you explain my reports in Spanish?

Yes. Kirby speaks English and Spanish fluently, so you can ask questions and go over your reports in either language.
