A profit and loss statement shows your business income, expenses and resulting profit or loss over a period. To read it, start with revenue at the top, subtract cost of goods sold to get gross profit, then subtract operating expenses to reach net profit, comparing each line against prior periods and your budget.
How to Read Your Profit and Loss Statement (And Actually Use It)
Most business owners I meet have a profit and loss statement sitting somewhere in their accounting software. Some of them look at it occasionally. Very few of them actually use it to run their business.
That’s a problem — because your P&L is one of the most powerful tools you have. When you know how to read it and what to look for, it tells you exactly where your business is making money, where it’s leaking money, and what decisions you need to make. When you ignore it, you’re running blind.
This post is for business owners, not accountants. I’m going to explain what a profit and loss statement actually tells you — in plain language — and show you how to use it to make better decisions every month.
What a Profit and Loss Statement Actually Shows You
Your P&L (also called an income statement) summarises your business’s financial performance over a period of time — usually a month, a quarter, or a financial year. It answers a simple question: did your business make money, and where did it come from (or go)?
The basic structure works like this;
- Revenue (Sales) — the total money your business brought in
- Less: Cost of Goods Sold (COGS) — the direct costs of delivering your product or service
- = Gross Profit — what’s left after your direct costs
- Less: Operating Expenses — rent, wages, marketing, subscriptions, insurance — the overhead costs of running the business
- = Net Profit (or Net Loss) — what the business actually made after everything
That’s the skeleton. Now let’s talk about what it actually means for you.
Gross Profit Margin: The Number That Tells You If Your Pricing Is Right
Your gross profit margin is your gross profit expressed as a percentage of revenue. It tells you how much of every dollar you earn stays in the business before you pay your overheads.
For example: if you generate $500,000 in revenue and your COGS is $300,000, your gross profit is $200,000 — that’s a 40% gross margin.
Why does this matter? Because your gross margin is a direct reflection of your pricing and your direct cost control. If your gross margin is shrinking over time, one of two things is happening: your prices are too low, or your delivery costs are going up. Either way, you need to know about it during the year — not at tax time.
Every industry has a benchmark gross margin. If you’re well below yours, that’s the first conversation to have. At Pinnacle, one of the first things I do with a new client is look at their gross margin by service line — and for most of them, we find that some jobs or service types are barely profitable once you account for the actual cost of delivery.
Operating Expenses: Where Most Business Owners Stop Paying Attention
Below the gross profit line, you’ll see your operating expenses — all the fixed and semi-fixed costs of running the business. This is where a lot of money quietly disappears.
The discipline here is to review each expense line every month, not just the total. Ask yourself:
- Is this expense generating revenue or protecting the business? If not, does it need to be there?
- Are there subscriptions or services you’re paying for that you’re not actually using?
- Has any line item grown significantly compared to last month or last year? Why?
The business owners who do this regularly find savings almost every time. Not always big ones — sometimes it’s $200 a month in software nobody uses, or a supplier contract that auto-renewed at a higher rate. But across twelve months, small leaks become large losses.
Equally important: don’t just try to cut expenses. Some expenses are investments. Marketing that generates $10 in revenue for every $1 spent is an expense you should be increasing. The P&L is not a cost-cutting exercise — it’s a profitability exercise.
Net Profit vs Cash in the Bank: Understanding the Difference
Here’s the thing that trips up almost every business owner I work with for the first time: profit and cash are not the same thing.
Your P&L might show a healthy net profit — but your bank account might be nearly empty. How does that happen?
Several ways. You might have revenue that’s been invoiced but not yet collected (debtors). You might have bought stock or equipment (which doesn’t show up on your P&L as an expense in the way you’d expect — it’s a balance sheet movement). You might have loan repayments coming out of your account that aren’t shown on the P&L. Or your profit might be real, but the tax bill on it is about to arrive.
This is why a P&L alone doesn’t tell the whole story. You also need to look at your cash flow statement and your balance sheet. But starting with the P&L — and understanding it properly — is the foundation.
If you’d like to understand the full picture of management accounting for your business, that’s a conversation I have with my clients regularly.
How to Actually Use Your P&L Each Month
Reading your P&L shouldn’t be a passive exercise. Here’s a simple monthly routine that takes about 30 minutes and will genuinely improve how you run your business:
- Pull your P&L for the month and year-to-date. Most accounting software (Xero, MYOB, QuickBooks) can produce this in seconds.
- Compare to last month and the same month last year. Look for anything that’s moved more than 10% in either direction. Ask why.
- Check your gross margin. Is it stable? Is it improving or declining?
- Scan the expense lines. Any surprises? Any categories running higher than expected?
- Calculate your net profit margin. Net profit divided by revenue. Is it where you need it to be to pay yourself properly, service any debt, and have something left over?
- Make one decision based on what you see. It doesn’t have to be dramatic — but the numbers should be driving at least one action each month.
This is the difference between using your accounts as a management tool and using them purely for compliance. Compliance keeps you out of trouble with the ATO. Management accounting helps you actually build wealth.
When to Get Help Reading Your Numbers
If you look at your P&L and still aren’t sure what it’s telling you — that’s completely normal, and it’s fixable. This isn’t something you have to figure out alone.
Part of what I do with my clients is go through the numbers together, in plain English, until they actually understand their business financially. Not so they become accountants — but so they can make good decisions. Because the business owner who understands their margins, their expense ratios, and their profit trends makes fundamentally better decisions than one who doesn’t.
If you’ve been avoiding your numbers because they feel overwhelming, let’s change that. A one-hour conversation can go a long way.

Frequently Asked Questions
How do I read a profit and loss statement?
Start at the top with revenue, subtract cost of goods sold to get gross profit, then subtract operating expenses to reach net profit. Compare each figure against previous periods and your budget to see trends and spot where money is really being made or lost.
What is the difference between gross profit and net profit?
Gross profit is revenue less the direct cost of producing your goods or services. Net profit is what remains after all operating expenses, such as rent, wages and admin, are also deducted. Net profit is the true bottom line of the business.
What should I look for in my P&L?
Look at revenue trends, gross profit margin, major expense lines, and net profit compared with prior periods and budget. Sudden changes, shrinking margins or creeping costs are the signals that need investigation and often prompt action.
How often should I review my profit and loss?
Review your P&L monthly, not just at tax time. Monthly review lets you catch margin erosion, rising costs or falling sales early, while there is still time to respond. Waiting until year end means problems have already cost you money.
