How to read a profit and loss statement, line by line
A profit and loss statement (P&L, or income statement) shows what a business earned and spent over a period, and what was left. Read it from the top: revenue, less the direct costs of delivering it, is gross profit; less operating expenses, the operating result; after other income, interest and tax, net income. Below, each line in turn, the margins to work out, what the statement leaves out, and a real example from a sample company's books.

What are the lines on a P&L, from top to bottom?
A P&L runs from revenue down to net income. Revenue minus cost of revenue gives gross profit. Gross profit minus operating expenses gives the operating result, often called EBIT. Other income and expenses, such as interest, come next, then tax. What is left after every cost is net income, the bottom line.
- Revenue (sales, turnover). What the business earned in the period from what it sells, usually split by product or service. On the accrual basis most businesses report on, it is counted when earned, not when the customer pays.
- Cost of revenue (cost of sales, cost of goods sold, direct costs). The costs that rise and fall with what you deliver: materials, hosting, payment fees, the people who do the work for customers.
- Gross profit = revenue - cost of revenue. Divided by revenue, it is the gross margin: how much of each dollar of sales is left to pay for everything else. See also gross profit.
- Operating expenses (overheads). The cost of running the business whatever the volume: salaries outside delivery, rent, software, marketing, insurance, professional fees. Often grouped, for example into research and development, sales and marketing, and general and administrative.
- Operating result (operating profit or loss, often called EBIT) = gross profit - operating expenses. Divided by revenue, it is the operating margin. Adding back depreciation and amortization gives EBITDA.
- Other income and expenses. Items outside day-to-day trading: interest received and paid, gains or losses on selling equipment, exchange differences.
- Tax on the profit, where the business pays it at company level.
- Net income (net profit, the bottom line). What is left after every cost. Divided by revenue, it is the net profit margin.
Worked example: Northbridge Analytics, September 2026
Northbridge Analytics is the sample company in Ataski's Financial Analyst workspace. This is the profit and loss in its sample monthly management report, built from one set of generated books, with each line shown as a share of revenue.
| Line | September 2026 | % of revenue |
|---|---|---|
| Revenue | ||
| Subscriptions — Starter | $13,920 | 8.5% |
| Subscriptions — Pro | $59,400 | 36.4% |
| Subscriptions — Enterprise | $77,650 | 47.6% |
| Implementation services | $9,000 | 5.5% |
| Usage overage | $3,186 | 2.0% |
| Total revenue | $163,156 | 100.0% |
| Direct costs (cost of revenue) | ||
| Cloud hosting and data warehouse | $19,306 | 11.8% |
| Payment processing fees | $2,260 | 1.4% |
| Support and solutions payroll | $22,436 | 13.8% |
| Total direct costs | $44,002 | 27.0% |
| Gross profit | $119,154 | 73.0% |
| Operating expenses | ||
| Research and development | $83,825 | 51.4% |
| Sales and marketing | $63,594 | 39.0% |
| General and administrative | $33,881 | 20.8% |
| Total operating expenses | $181,300 | 111.1% |
| Operating result | −$62,146 | −38.1% |
| Other income less other expenses | $0 | 0.0% |
| Net income | −$62,146 | −38.1% |
- Revenue $163,156 came from 5 lines; the largest, Subscriptions — Enterprise, is 47.6% of it. A business that depends on one line is exposed if that line slows.
- Gross profit $119,154 after $44,002 of direct costs: a gross margin of 73.0%.
- Operating expenses $181,300. The largest group, Research and development, alone equals 51.4% of revenue.
- Operating result −$62,146: an operating margin of −38.1%.
- Net income −$62,146. The sample's books carry no other income, other expenses, interest or tax, so net income equals the operating result.
One month means little on its own. The same report sets each total beside the prior month and the same month last year:
| Line | Sep 26 | Aug 26 | Sep 25 |
|---|---|---|---|
| Revenue | $163,156 | $144,547 | $117,890 |
| Direct costs | $44,002 | $43,162 | $35,967 |
| Gross profit | $119,154 | $101,386 | $81,923 |
| Operating expenses | $181,300 | $182,701 | $159,359 |
| Operating result | −$62,146 | −$81,315 | −$77,436 |
What should you compare a P&L against?
Read it against four things: the prior month, which shows direction; the same month last year, which removes seasonality; the budget, which shows whether the business is on plan; and revenue itself, where each line as a share of revenue shows whether a cost is growing faster than sales.
- The prior month shows direction: what grew, what shrank.
- The same month last year removes seasonality, and shows the revenue growth rate over a full year.
- The budget shows whether the business is on plan. The variance analysis guide covers how to explain the differences.
- Revenue itself. Each line as a share of revenue, as in the table above, shows whether a cost is growing faster than sales.
What does a P&L not show?
It does not show cash, or what the business owns and owes. Revenue is counted when earned and costs when incurred, not when money moves, so late payers, stock, loan repayments and equipment purchases use cash without appearing as costs. Receivables, stock, debt and equity are on the balance sheet; read the two together.
Cash. Revenue is counted when earned and costs when incurred, not when money moves. Customers paying late, stock building up, loan repayments and equipment purchases all use cash without appearing as a cost on the P&L. At Northbridge Analytics, cash moved by −$90,515 over the month, from $1,544,959 to $1,454,444: −$62,146 from the operating result and −$28,370 from working capital and timing, such as invoices not yet collected, bills not yet paid and payments received in advance. For the cash view, see operating cash flow and the 13-week cash flow forecast.
What the business owns and owes. Receivables, stock, debt and equity are on the balance sheet. Read the two together: a strong month on the P&L with receivables climbing fast is a cash problem in waiting.
Questions to ask of any P&L
- Is revenue growing, and from which lines?
- Is the gross margin steady, or are direct costs rising faster than sales?
- Which operating expenses grew faster than revenue, and was that planned?
- Is the result driven by a one-off item that will not repeat?
- Does the cash position tell the same story?
Xero and QuickBooks Online both produce the statement as a report called Profit and Loss. For the full monthly pack built around it, see the monthly management report template and the KPIs worth tracking every month.
Or have it written for you
Ataski's Financial Analyst reads the profit and loss from your accounting system every month and writes the management report around it: each line against the prior month, the same month last year and the budget, and each line that moved explained by the accounts that moved it.
- Your ledger. QuickBooks Online and Xero; NetSuite, Sage Intacct, Zoho Books and Business Central in beta.
- Every month on the 1st. The report is refreshed on the 1st of every month for the month just ended, as a draft that waits for your approval.
- History from day one. The first connection reads the trailing 24 months, so the first report already compares each month with the same month last year.
- Cash, 13 weeks out. A weekly cash forecast beside the open invoices and bills falling due.
- A second reviewer. A second, independent AI reviewer reads every monthly narrative, and an AI explanation that cites a source outside your books is discarded, not published.
Plans start at $599/mo. The first month is free, and no card is needed to start it.
Questions
What is the difference between gross profit and net profit?
Gross profit is revenue minus the direct costs of delivering it. Net profit, or net income, is what remains after every cost: direct costs, operating expenses, other items such as interest, and tax.
Is a profit and loss statement the same as an income statement?
Yes. Profit and loss statement, P&L, income statement and statement of operations are names for the same report: revenue and expenses over a period, and the profit or loss that results.
What is operating profit?
Gross profit minus operating expenses: what the business earns from its normal trading before other income and expenses, interest and tax. It is often called EBIT, earnings before interest and tax.
Why can a profitable business run out of cash?
Because the P&L counts revenue when it is earned and costs when they are incurred, not when cash moves. Customers paying late, stock building up, loan repayments and equipment purchases all use cash without appearing as costs. Read the P&L next to a cash flow statement or a cash forecast.
What period should a P&L cover?
Any period: a month, a quarter or a year. To run a business, a monthly P&L set against the prior month, the same month last year and the budget is the most useful view, with the year to date for the bigger picture.
