Note: ATO cost of sales figures exclude labour. If you've included delivery labour in direct costs above, your gross margin will sit lower than ATO-only benchmarks — this reflects your true delivery economics and is expected.

How to Use This Calculator
Follow these five steps to get your gross margin, net margin, and an industry benchmark comparison in under a minute.
Select Monthly or Annual using the toggle at the top. Monthly works best with accounting software figures. Annual works best with your end-of-year P&L.
Type your total revenue for the period: the top-line sales figure before any costs. Do not include GST.
Enter materials, stock, and delivery labour. Use “Break down my costs” to enter Labour, Materials, Subcontractors, and Other separately.
Optional – rent, utilities, admin wages, software, insurance. Leave blank to see gross margin only. Fill in to see your net margin.
Choose from the dropdown. The calculator compares your margin to ATO benchmarks and shows a green/amber/red health signal with plain-English advice.
Understanding Your Results
Knowing your margin percentage is only useful if you know what it means. Here’s a plain-English breakdown of the three figures this calculator produces, and why each one matters for your business.
Gross Profit Margin
Your gross profit margin shows how much revenue remains after subtracting the direct costs of delivering your product or service. It tells you how efficiently your business converts sales into profit before overheads are factored in.
If your gross margin is 55%, for every dollar of revenue, 55 cents remains to cover wages, rent, software, and profit. A weak gross margin is usually a pricing problem, a cost-of-goods problem, or both.
Net Profit Margin
Your net profit margin deducts all operating expenses: rent, admin wages, utilities, software, insurance from gross profit. The result is what the business actually earns after every cost is paid.
A business can have a healthy gross margin and a poor net margin. That combination usually means overheads are too high for the current revenue level.
Margin vs Markup
Markup is calculated as a percentage of your cost. If something costs $60 and sells for $100, your markup is 67%.
Margin is calculated as a percentage of your revenue. On that same transaction, your gross margin is 40%.
A 67% markup does not produce a 67% margin. It produces a 40% margin. Many businesses underprice because they confuse the two.
| Metric | What it measures | Formula | When to use |
|---|---|---|---|
| Gross margin | Profitability after direct costs | (Rev − DC) ÷ Rev | Pricing decisions, product viability |
| Net margin | Profitability after all costs | (Rev − All costs) ÷ Rev | Business health, sustainability |
| Markup | Price premium over cost | GP ÷ Direct costs | Setting prices from known cost |
Gross margin tells you whether your product or service is profitable. Net margin tells you whether the whole business is. Both matter, but for different reasons.
Australian Industry Profit Margin Benchmarks
Not all margins are created equal. A 15% gross margin that would be catastrophic for a consulting firm is perfectly normal for a supermarket. The benchmarks below come from the ATO’s Small Business Benchmark data (2022–23 financial year, updated March 2025). The same data the ATO uses to assess whether small business tax returns are consistent with industry norms.
| Industry | Healthy Gross Margin | Healthy Net Margin | Data source |
|---|---|---|---|
| Café / Hospitality | 55–65% | 2–8% | ATO 2022–23: Coffee Shops, Restaurants |
| Trades / Construction | 35–50% | 13–24% | ATO 2022–23: Plumbing, Electrical Services |
| Retail | 42–59% | 9–28% | ATO 2022–23: Clothing Retailing |
| Professional Services | 50–70% | 15–25% | CA ANZ 2024; ATO 2022–23 basis |
| Health / Allied Health | 55–75% | 15–25% | CA ANZ 2024; ABS health industry data |
| E-commerce | 35–60% | 5–15% | ABS; Unleashed Software AU GMI Q2 2025 |
| Other / General SME | 40–60% | 7–15% | ATO Taxation Statistics 2022–23 |

Benchmarks reflect the middle range of reported business performance and are directional guides only. The ATO reports cost of sales excluding labour. Margins calculated on total direct costs including labour will naturally sit lower.
Cafés often show strong gross margins (55–65%) but very thin net margins (2–5%). Labour, rent, and utilities consume most of what's left after food and beverage costs. A healthy gross margin in hospitality does not guarantee a healthy business. The net margin is the number that matters most.
How to Improve Your Profit Margin
If your margin is below benchmark, the instinct is often to chase more revenue. But revenue growth without margin improvement just scales a problem. Here are the four levers that actually move the needle, and the order in which to pull them.
Review Your Pricing
Pricing is the single highest-leverage change you can make to your margin. A 5% price increase on $1M of revenue produces $50,000 of additional gross profit with no additional cost. Most business owners undercharge because they haven’t reviewed rates recently, or fear losing clients. If your margins are below benchmark, a selective price increase is almost always less risky than the alternative.
Audit Your Direct Costs
If pricing isn’t the issue, look at what you’re spending to deliver. Renegotiate supplier terms. Review subcontractor rates. Identify waste in materials or labour. Even a 2–3% reduction in your cost of goods can meaningfully shift your gross margin. For trades and hospitality, food and materials cost are the most common culprits. For professional services, it’s often delivery labour running over on fixed-price work.
Control Your Overheads
A healthy gross margin paired with a poor net margin is almost always an overhead problem. Go through your operating expenses line by line. Software subscriptions, insurance renewals, and office costs often drift upward year on year without a corresponding increase in output. Target overheads at 15–25% of revenue. If you’re above that, there is almost certainly room to cut.
Improve Your Revenue Mix
Not all revenue is equally profitable. Identify your highest-margin work and deliberately shift more effort toward it. This doesn’t require winning more clients – it requires winning better work from the clients you already have. Even moving 20% of your capacity toward your most profitable work or product can add 3–5 percentage points to net margin without a single price increase.
If you’ve worked through these four levers and are still not sure where the problem is, that’s where a structured financial review helps. The numbers will tell you, but you just need someone to read them properly.

Frequently Asked Questions
A good net profit margin for an Australian small business is generally 10–15%. Below 5% is considered fragile — one bad quarter can create real pressure. Above 15% is strong, particularly for service businesses with low overhead. The right benchmark depends heavily on industry: a 5% net margin is acceptable for a café but would be a serious concern for a management consulting firm. Use the ATO's industry-specific benchmarks as your reference point, not a general average.
Gross profit margin measures what remains after subtracting the direct costs of delivering your product or service — materials, stock, and delivery labour. Net profit margin goes further, deducting all operating expenses including rent, admin wages, utilities, and software. Gross margin tells you whether your product or service is inherently profitable. Net margin tells you whether the whole business is. A business can have a healthy gross margin and still lose money if overheads are too high.
To calculate gross profit margin: subtract your direct costs from your revenue to get gross profit, then divide gross profit by revenue and multiply by 100. The formula is: (Revenue − Direct costs) ÷ Revenue × 100. For example, if your monthly revenue is $50,000 and your direct costs are $20,000, your gross profit is $30,000 and your gross margin is 60%. Use the calculator above to do this instantly and compare against Australian industry benchmarks.
Margin is gross profit expressed as a percentage of revenue. Markup is gross profit expressed as a percentage of cost. They measure the same dollar figure from different angles. If something costs $60 and sells for $100, the markup is 67% but the margin is 40%. This distinction matters in pricing: if you apply a 50% markup to all your products, your gross margin will be 33% — not 50%. Many businesses underprice precisely because they confuse the two.
Net profit margin is the percentage of revenue remaining after all costs — direct costs and operating expenses — have been deducted. It is the truest measure of business profitability. Revenue growth means nothing if net margin is thin or negative. For Australian small businesses, a net margin of 10–15% is considered healthy. The ATO uses net profit ratios alongside gross margin data when assessing whether a business's tax return is consistent with industry norms for its size and sector.
Revenue growth can mask a margin problem. If costs are growing faster than revenue — through additional staff, higher materials costs, or expanded premises — your margin will shrink even as your top line grows. The most common causes are: taking on lower-margin work to fill capacity, allowing overheads to drift upward without review, and underpricing new work to win volume. Check whether your wages-to-revenue ratio and overhead-to-revenue ratio are increasing year on year — that's usually where the answer sits.
The ATO publishes small business benchmarks for over 100 industries based on aggregated tax return data. If your gross margin is below the benchmark range for your industry and turnover, it can indicate one of three things: your direct costs are higher than typical peers (pricing or supplier issue), you are underreporting income (which the ATO flags), or your business model differs from the industry average in a legitimate way. Falling outside the range is not automatically a problem, but it warrants a review — and a clear explanation if you're ever asked.
Monthly is the right cadence for most small businesses. Reviewing margins quarterly risks missing cost spikes — a supplier price increase or an unexpected wages blowout — until they've already done damage. A monthly review doesn't need to be complex: pull your profit and loss from Xero or MYOB, calculate your gross and net margin, and compare against last month and last year. If either margin has moved more than 2–3 percentage points, investigate before it becomes a larger problem.
For cafés and coffee shops, the ATO's 2022–23 benchmarks show a healthy cost of sales (food and beverage costs) of 33–41% of turnover — implying a gross margin of 59–67%. For restaurants, the equivalent range implies a gross margin of 61–67%. These figures exclude labour. When delivery labour is included in direct costs, effective gross margins in hospitality typically sit at 40–55% for well-run businesses. If your margin is below 40% including labour, a menu pricing review is the likely priority.
Three levers move net margin without touching prices. First, reduce direct costs: renegotiate supplier terms, reduce materials waste, or tighten subcontractor rates. Second, audit overheads line by line — software subscriptions, insurance, and office costs often accumulate quietly and can typically be reduced 10–15% with a focused review. Third, shift your revenue mix toward higher-margin work or products. Even moving 20% of your effort toward your most profitable work or client type can add 3–5 percentage points to net margin without a single price increase.
