About the Net & Gross Profit Margin Calculator
The Net & Gross Profit Margin Calculator Australia gives you a clear view of your business profitability at two levels. Gross profit margin shows how efficiently you produce or source your products, while net profit margin reveals your overall profitability after all expenses. Both numbers are essential for Australian business owners managing their tax obligations with the ATO. The RBA and ASIC both emphasise the importance of maintaining healthy profit margins as a buffer against economic downturns. This calculator helps you track both margins over time, identify trends, and benchmark against Australian industry standards. Whether you are pricing a new product or reviewing annual performance, these metrics are indispensable.
What is the Net & Gross Profit Margin Calculator?
This calculator computes two essential profitability ratios. Gross profit margin is (Revenue − Cost of Goods Sold) / Revenue × 100. It measures the percentage of revenue retained after covering direct production costs. Net profit margin is Net Profit / Revenue × 100. Net profit is revenue minus all expenses including COGS, operating expenses, interest, and tax. For Australian businesses, understanding the gap between gross and net margin is critical. A healthy gross margin can be eroded by high operating costs such as rent, wages, marketing, and ATO payments. The calculator helps you identify where margin is being lost so you can take corrective action. It also assists with BAS preparation by clarifying your profitability position before tax obligations.

Worked Australian Example
Practical Example
Consider Geelong Fashion Studio, a clothing boutique in Victoria. For the 2025–26 financial year, the business reports: Total revenue: $520,000 (GST-exclusive). Cost of goods sold: $210,000. Operating expenses: $195,000 including rent $48,000, wages $92,000, marketing $18,000, utilities $9,000, insurance $6,000, loan interest $12,000, depreciation $10,000. Tax expense: $28,000. Gross profit = $520,000 − $210,000 = $310,000. Gross profit margin = $310,000 / $520,000 × 100 = 59.6%. Net profit before tax = $520,000 − $210,000 − $195,000 = $115,000. Net profit after tax = $115,000 − $28,000 = $87,000. Net profit margin = $87,000 / $520,000 × 100 = 16.7%. For the Australian retail clothing sector, a gross margin around 55–60% and net margin around 10–15% is typical. The studio is performing well on both fronts. If the owner wants to improve net margin further, reducing rent through renegotiation or improving inventory turnover would be logical next steps.
