A profit margin measures how much of your revenue you keep as profit, expressed as a percentage. The two key margins are gross margin (revenue less direct costs) and net margin (revenue less all costs). Understanding and tracking them shows whether your business is truly profitable, not just busy.
Margin is also routinely confused with markup, and that single mix-up quietly costs trade businesses thousands. If you price jobs by adding a percentage to cost, read our guide to markup vs margin for tradies.
One overhead that now sits directly inside your margin is card acceptance. From 1 October 2026 the card surcharge ban means you can no longer pass card fees to customers, so they have to be built into your pricing.
Your business turned over $800,000 last year. Sounds impressive, right? But if you walked away with $40,000 after all the costs were paid, you’re running on a 5% net profit margin — and that’s a problem worth understanding before it becomes a crisis.
Many small business owners focus almost entirely on revenue. They celebrate hitting a turnover milestone while quietly ignoring the question that actually matters: how much of that revenue are you keeping?
Profit margin is the metric that answers that question. In this guide, we’ll explain exactly what profit margin is, the critical difference between gross and net margin, what healthy margins look like across different Australian industries, and — most importantly — what you can do to improve yours.
What Is a Profit Margin?
A profit margin is a percentage that tells you how much profit your business makes for every dollar of revenue it earns. It’s one of the most fundamental measures of business health — and one of the most commonly misunderstood.
Here’s the basic idea: if your business earns $100 in revenue and spends $80 to produce that revenue, your profit is $20 and your profit margin is 20%.
Simple enough — but there are two distinct types of profit margin that every business owner needs to understand. Confusing them leads to some very costly misreads of your financial position.
Gross Profit Margin vs Net Profit Margin
This is where most business owners either switch off or get confused. Let’s make it clear.
Gross Profit Margin
Gross profit margin measures how much profit you make after deducting your direct costs — also called the Cost of Goods Sold (COGS). These are the costs that go directly into delivering your product or service: materials, direct labour, stock, and manufacturing costs.
Formula:
Gross Profit Margin = (Revenue – COGS) ÷ Revenue × 100
Example: A Melbourne café turns over $500,000 per year. Their Cost of Goods Sold — coffee beans, food supplies, barista wages — totals $200,000.
- Gross Profit = $500,000 – $200,000 = $300,000
- Gross Profit Margin = $300,000 ÷ $500,000 × 100 = 60%
A 60% gross margin means the café keeps 60 cents of every revenue dollar after covering its direct costs. That’s a strong gross margin for the food and beverage industry.
Net Profit Margin
Net profit margin goes further — it measures what’s left after ALL costs are paid: COGS, overheads, rent, utilities, insurance, salaries, marketing, accountant fees, interest on loans, and tax.
Formula:
Net Profit Margin = Net Profit After Tax ÷ Revenue × 100
Back to our café: After paying rent ($80,000), utilities ($15,000), management wages ($90,000), marketing ($10,000), insurance ($5,000), and tax, the net profit comes to $60,000.
- Net Profit Margin = $60,000 ÷ $500,000 × 100 = 12%
A 60% gross margin but only a 12% net margin. This is extremely common — and it illustrates why looking at gross margin alone can give you a dangerously flattering picture of your business.
The gap between gross and net margin is your overhead burden. Too wide a gap and you’re working incredibly hard for a very thin slice of the pie.
What’s a Good Profit Margin for a Small Business?
This depends heavily on your industry. There’s no single “good” profit margin number — but there are typical ranges you can benchmark against.
| Industry | Typical Gross Margin | Typical Net Margin |
|---|---|---|
| Professional Services (accounting, legal, consulting) | 60–80% | 20–40% |
| Trades (plumbing, electrical, construction) | 30–50% | 10–20% |
| Retail | 30–50% | 5–15% |
| Food & Beverage / Hospitality | 55–70% | 3–12% |
| E-commerce | 20–45% | 5–15% |
| Healthcare / Allied Health | 50–70% | 15–25% |
If your margins are consistently below the low end of your industry range, that’s a red flag worth investigating. If you’re not sure where your business sits, that’s exactly the kind of conversation worth having with a business adviser.
You can also find general business performance data through the ATO’s small business benchmarks — they publish industry-specific financial ratios that let you see how your numbers compare to similar businesses across Australia.
Why Profit Margin Matters More Than Revenue
Revenue is easy to talk about. “We turned over $1.2 million this year” sounds impressive. But it tells you almost nothing about whether the business is actually healthy.
Consider two Melbourne plumbing businesses:
- Business A: $1.2 million revenue, 8% net margin → $96,000 net profit
- Business B: $700,000 revenue, 22% net margin → $154,000 net profit
Business B earns $58,000 more in profit despite turning over $500,000 less. Which business would you rather own?
This is the fundamental insight at the heart of this business planning series. In Part 1 of this series, we worked backwards from your personal income need to calculate the exact revenue target your business must hit. But that revenue target is entirely dependent on your profit margin:
Revenue Needed = Required Profit ÷ Profit Margin %
If your required profit is $150,000 and your net margin is 15%, you need $1,000,000 in revenue. If you could improve that margin to 25%, you’d only need $600,000 to achieve the same outcome — with significantly less stress, fewer clients to manage, and more time back in your week.
Margin isn’t just a financial metric. It’s a measure of your leverage. High-margin businesses can scale, invest, and weather economic downturns. Low-margin businesses are always running just to stand still.

The good news: profit margin is something you can actively manage. Here are six practical strategies that work across most business types.
1. Increase Your Prices
This is the most powerful lever most business owners are afraid to pull. A 10% price increase on a $500,000 turnover adds $50,000 in revenue — and because your costs don’t change, almost all of that flows straight to profit.
Many small businesses haven’t raised prices in years, even as their own costs have risen. If you haven’t reviewed your pricing since before 2022, you’re almost certainly undercharging. Clients who genuinely value your work rarely leave over a 5–10% adjustment. Those who do are often your least profitable clients anyway.
2. Reduce Your Cost of Goods Sold
Review what you’re paying for materials, stock, and direct service delivery. Can you renegotiate supplier contracts? Are you ordering in volumes that attract better pricing? Could you substitute materials without compromising quality?
A 5% reduction in COGS on a 40% gross margin business can translate to a meaningful jump in net margin — without winning a single new client.
3. Cut Waste and Overhead Creep
Every business has overhead creep — subscriptions nobody uses, insurance policies that haven’t been reviewed in years, duplicate software tools, and staff time spent on tasks that don’t generate revenue.
A quarterly overhead review of your Profit & Loss statement can reveal surprising savings. This is especially valuable when done with a business adviser who can spot patterns you can’t see from inside your own business.
4. Upsell and Improve Your Client Mix
Not all revenue is created equal. A client paying $500/month for a simple, well-systemised service is often far more profitable than one paying $2,000 for complex, time-intensive work that requires constant management.
Look at which services or product lines carry your highest margins and deliberately grow those. Consider whether your lowest-margin work is worth keeping — or whether that capacity could be deployed more profitably elsewhere.
5. Improve Productivity and Eliminate Rework
Time is your most expensive resource. Rework, inefficient processes, and manual tasks that could be automated eat into your margin without showing up clearly on your P&L.
Systemising recurring work, improving staff onboarding, and investing in the right tools often produces the same bottom-line result as winning more business — but with far less effort.
6. Stop Discounting to Win Work
Discounting is one of the quickest ways to destroy your margin. If your gross margin is 40% and you offer a 10% discount to close a deal, you’ve surrendered 25% of your profit from that job before you’ve lifted a finger.
Build confidence to hold your pricing. Add value instead of cutting price — better service delivery, faster turnaround, stronger guarantees. The clients worth having will recognise it.

How Profit Margin Connects to Your Revenue Target
This is where everything in this series ties together.
In Part 1 of this business planning series, we showed you how to work backwards from your personal income need to calculate exactly how much revenue your business must generate — factoring in tax, superannuation, and the profit your business needs to be financially sustainable.
Your gross profit margin is the linchpin of that calculation:
Revenue Target = Required Profit ÷ Net Profit Margin %
Knowing your profit margin isn’t just an accounting exercise — it’s the foundation of every meaningful business decision. Hiring a new team member? You need to know what margin that investment will dilute. Considering a new service line? You need to know whether it will carry the margin your business requires. Setting prices for next financial year? Margin is your starting point.
Our Virtual CFO service at Pinnacle is specifically designed to give small business owners this kind of ongoing financial clarity — not just at tax time. Understanding your margins, your benchmarks, and your improvement levers is exactly what strategic financial partnership delivers.
In Part 3 of this series, we go one level deeper: breaking down your fixed and variable costs and calculating your break-even point — the minimum revenue your business must generate before it starts making a profit. That number is one of the most important figures any business owner can know, and most have never calculated it.

What is gross profit margin and why does it matter?
Gross profit margin measures how much revenue remains after deducting your direct costs (Cost of Goods Sold). It tells you how efficiently you’re delivering your product or service before overheads are applied. A high gross margin gives your business room to absorb fixed costs and still make a profit — a low one means you’re already under pressure before the bills arrive.
What’s the difference between gross profit margin and net profit margin?
Gross profit margin accounts only for direct costs (COGS), while net profit margin accounts for all costs including overheads, rent, salaries, interest, and tax. Net profit margin is the true measure of what your business actually keeps from every dollar of revenue. It’s entirely possible to have a strong gross margin but a very weak net margin if your overhead structure is too heavy.
What is a good profit margin for a small business in Australia?
It depends on your industry. Professional services typically see net margins of 20–40%, trades 10–20%, and retail 5–15%. Hospitality often operates on very thin net margins of 3–12% despite strong gross margins. The key is to know your industry benchmark and understand why you’re above or below it. A business adviser familiar with your sector can put your numbers in proper context.
How do I calculate my profit margin?
For gross profit margin: subtract your Cost of Goods Sold from your revenue, divide by revenue, and multiply by 100. For net profit margin: take your net profit after all expenses and tax, divide by revenue, and multiply by 100. If you use accounting software like Xero, these figures will be available in your Profit & Loss report. Your accountant can also calculate and interpret them for you.
Can I improve my profit margin without raising prices?
Yes — but price increases are often the most effective lever. Alternatives include reducing your Cost of Goods Sold through better supplier terms, cutting unnecessary overhead, improving productivity, upselling higher-margin services, and eliminating discounting. In practice, businesses that improve margin fastest usually address both the revenue and cost sides simultaneously. Our tax planning service also ensures you’re not paying more tax than necessary — which directly impacts your net margin.
How does profit margin connect to my revenue target?
Your profit margin is the key variable in calculating your revenue target. As we explained in Part 1 of this series, your revenue target equals your required profit divided by your net profit margin percentage. The higher your margin, the less revenue you need to achieve the same income goal — which is why improving margin is often a smarter strategy than simply chasing more revenue.

Understanding your profit margin is step one. The next step is knowing exactly where your break-even point sits — and how much revenue you need to cross it.

Improving the margin is only half the job. The other half is collecting it, because on an accruals basis you are taxed on that margin whether or not the client pays. See our guide to debtor management for how to turn margin into cash.
Frequently Asked Questions
What is a profit margin?
A profit margin is the percentage of revenue you keep as profit after costs. Gross margin measures profit after the direct costs of goods or services, while net margin measures profit after all expenses. Margins show how efficiently your business turns sales into profit.
How do I calculate profit margin?
Divide profit by revenue and multiply by 100. For gross margin use gross profit (revenue less direct costs); for net margin use net profit (revenue less all costs). Tracking both over time reveals whether your profitability is improving or slipping.
What is a good profit margin?
It depends heavily on your industry, so compare against your own history and industry benchmarks rather than a single ideal number. What matters is understanding your margin, knowing what drives it, and watching whether it is stable, growing or shrinking.
How can I improve my profit margins?
Improve margins by raising prices where the market allows, reducing direct and overhead costs, focusing on your most profitable products or clients, and cutting waste. Small, consistent margin gains often lift profit far more than chasing extra sales.
