- A profit and loss statement shows whether your business made a profit or a loss over a set period by taking revenue and subtracting costs and expenses.
- Gross profit is revenue minus the cost of goods sold, while net profit is what remains after all operating costs, interest and tax.
- Reading your P&L monthly, not just at tax time, helps you catch margin and cost trends early and understand your true profit.
A profit and loss statement is one of the most useful reports you will ever run for your business, yet plenty of founders have never really sat down and read one. If you are a sole trader or run a small company, understanding your true profit shouldn’t feel like decoding a foreign language. This guide walks through what a P&L actually shows, the line items in plain English, and a worked Australian example you can follow line by line. Whether you keep your own books or work with a small business accountant, you will come away able to read yours with confidence.
What is a profit and loss statement?
A profit and loss statement (also called an income statement) is a financial report that summarises a business’s revenue, costs and expenses over a set period, such as a month, quarter or financial year, to show whether it made a profit or a loss. It is one of the three core financial statements alongside the balance sheet and cash flow statement. In Australia it is used to track performance, prepare your tax return, and understand your true net profit after all expenses.
Put simply, it answers one question: over this period, did more money come in than went out? A P&L measures performance across a stretch of time, so it always covers a period rather than a single date. That is what separates it from the balance sheet, which captures a moment. Together with the cash flow statement, the three make up the set of general purpose financial statements most businesses rely on.
What’s included in a P&L? The line items explained
A profit and loss statement follows a consistent order, working from your total sales at the top down to what you actually keep at the bottom. Reading it top to bottom tells a story about where your money goes.
The core lines, in order, are:
- Revenue (sales): the total income your business earned from its work before any costs.
- Cost of goods sold (COGS): the direct costs of delivering that work, such as materials, stock or subcontractors.
- Gross profit: revenue minus COGS. This is what’s left to cover everything else.
- Operating expenses: the running costs of the business, like wages, rent, software and marketing.
- Operating profit: gross profit minus operating expenses.
- Other income and expenses: items outside day to day trading, such as interest on a loan.
- Net profit before tax: operating profit adjusted for that other income and expense.
- Income tax: for a company, the tax due on its taxable income.
- Net profit after tax: the final figure the business keeps, often called the bottom line.
Each line builds on the one above it, so a change near the top ripples all the way down.
Gross profit vs net profit: what’s the difference?
The difference between gross profit and net profit trips up a lot of business owners, and it matters because they answer different questions.
Gross profit is revenue minus the direct cost of what you sold. It tells you how profitable your core product or service is before the overheads of running the business. Net profit is what remains after every other cost, including wages, rent, interest and tax. It tells you what the business genuinely earned.
You can have a healthy gross profit and still make a net loss if your overheads are too high. That gap is exactly why reading the whole statement, rather than glancing at sales, is worth the few minutes it takes.
A simple profit and loss statement example (Australian small business)
Here is an illustrative P&L for a fictional company, Brightpath Consulting Pty Ltd, for the year ended 30 June. The figures are examples only and are shown GST-exclusive, which is how a P&L is normally read.
| Line item | Amount (A$) |
|---|---|
| Revenue (sales) | 220,000 |
| Cost of goods sold | (66,000) |
| Gross profit | 154,000 |
| Wages and superannuation | (70,000) |
| Rent | (24,000) |
| Software and subscriptions | (6,000) |
| Marketing | (8,000) |
| Other operating costs | (12,000) |
| Operating profit | 34,000 |
| Interest expense | (2,000) |
| Net profit before tax | 32,000 |
| Income tax (25% base rate) | (8,000) |
| Net profit after tax | 24,000 |
Reading down the table, Brightpath earned A$220,000 in sales, spent A$66,000 delivering the work, and was left with A$154,000 of gross profit. After A$120,000 of operating expenses and A$2,000 of interest, net profit before tax came to A$32,000. Company tax at the 25% base rate entity rate takes A$8,000, leaving A$24,000 kept in the business. We will refer back to these same numbers below.
TIPBuild one sample P&L like this for your own business and keep it handy. Once you can name every line, reading a real statement each month becomes a five-minute habit rather than a chore.
How to read your P&L: the numbers that actually matter
You don’t need to study every line to get value from a profit and loss statement. A few numbers tell you most of what you need.
Start with your margins. Brightpath’s gross margin is A$154,000 divided by A$220,000, or 70%, and its net margin before tax is A$32,000 divided by A$220,000, about 15%. Watching how these move month to month shows whether your pricing and costs are holding up.
Then look at trends rather than single figures. Is revenue climbing while gross margin slips? That can signal rising delivery costs or discounting. Are operating expenses creeping up faster than sales? Comparing the same line across periods is where a P&L earns its keep, and it is where many avoidable accounting mistakes get caught early.
Profit and loss vs balance sheet vs cash flow statement
The three core statements answer different questions, and business owners often confuse them. This table shows what each one measures.
| Statement | What it measures | Period covered | Key question answered |
|---|---|---|---|
| Profit and loss | Revenue, costs and profit | Over a period | Did we make a profit? |
| Balance sheet | Assets, liabilities and equity | At a point in time | What do we own and owe? |
| Cash flow statement | Money moving in and out | Over a period | Where did the cash go? |
A profit and loss statement can show a healthy profit while your bank balance looks thin, because profit is not the same as cash. That is why the three work as a set. For the companion piece, see the balance sheet explainer.
Cash vs accrual: when does income and expense show up?
When a sale or cost lands on your P&L depends on your accounting method. Under the cash basis, you record income and expenses when money actually moves. Under the accrual basis, you record them when they are earned or incurred, even if payment comes later.
The method changes the timing of what appears on your statement, so the same business can show different monthly profit depending on which basis it uses. In Australia, businesses with an aggregated turnover under $10 million can generally choose either basis for GST, while most larger businesses must use the accrual (non-cash) method. For the full comparison, see cash vs accrual accounting.
How often should you review your profit and loss statement?
A once a year look at tax time is the most common habit, and it is the one that costs owners the most. By then the numbers are history and there is little you can do about them.
A monthly review is the sweet spot for most small businesses. It is frequent enough to catch a margin slip or a cost blowout while you can still act, without becoming a burden. Quarterly reviews tie in neatly with BAS preparation. However you space it, the point is to look while the information is still useful. Accounting software like Xero produces a P&L on demand, so the barrier is habit, not tools.
How Sleek helps you understand your profit and loss statement
Reading a P&L is one thing; getting an accurate one every month is another. Sleek runs bookkeeping and accounting as core Australian services, on Xero and at a fixed monthly fee, so your profit and loss statement is prepared, reconciled and ready to talk through rather than pieced together at year end. If you are a sole trader or freelancer, accounting for freelancers and sole traders covers the same ground at a scale that suits you.
The result is a monthly P&L you can actually read, from an accountant who can explain what each line means for your business.

Frequently Asked Questions
Is a profit and loss statement the same as an income statement?
Yes. The two terms describe the same report. “Income statement” is more common in the United States, while “profit and loss statement” or “P&L” is used more often in Australia. Both summarise revenue, costs and profit over a period.
How often should a small business do a P&L?
Monthly is ideal for most small businesses, with quarterly reviews aligned to BAS as a minimum. Accounting software can generate one at any time, so the constraint is usually how often you review it rather than how often it can be produced.
Does a sole trader need a profit and loss statement?
A sole trader is not legally required to file one, but a P&L is still worth keeping. It shows your true profit, supports your individual tax return, and is often requested when you apply for finance or a lease.
What is the difference between a P&L and a balance sheet?
A profit and loss statement shows performance over a period, while a balance sheet shows your financial position at a single point in time. The P&L answers “did we make a profit”; the balance sheet answers “what do we own and owe”.
Can I create a profit and loss statement in Xero?
Yes. Xero generates a profit and loss report from your reconciled transactions, and you can run it for any date range. The accuracy of the report depends on your bookkeeping being kept up to date.
Does the ATO require a profit and loss statement?
Companies generally need to prepare a P&L to complete their company tax return, and the figures feed your reported income and deductions. Sole traders report business income and expenses through the individual return, and a P&L is the practical way to arrive at those figures.
Why does my P&L show a profit when my bank account is low?
Profit is not the same as cash. A P&L can show earnings that customers have not paid yet, or exclude loan repayments and asset purchases that drain your account. Reading it alongside your cash flow statement gives the full picture.
