What is gross profit margin?
Gross profit margin is a financial metric that measures the percentage of revenue a business retains after deducting the direct costs of producing its goods or services (known as Cost of Goods Sold, or COGS). It is expressed as a percentage and provides a clear picture of how efficiently a business is producing and selling its products.
The formula for gross profit margin is:
Gross Profit Margin = [(Revenue – COGS) ÷ Revenue] × 100
For example, if a business generates $100,000 in revenue and incurs $40,000 in COGS, the gross profit is $60,000, giving a gross profit margin of 60%.
What is a healthy gross profit margin?
A good gross profit margin varies significantly by industry. As a general guide:
- Retail and manufacturing businesses often target a gross profit margin of 50–70%
- Service-based businesses such as law firms or consultancies may achieve margins in the 80–90%+ range
- Food service and hospitality businesses typically operate on much tighter margins of 3–15%
Comparing your gross profit margin against industry benchmarks is more meaningful than applying a universal standard.
Why gross profit margin matters
Gross profit margin directly influences your business’s ability to cover operating expenses, invest in growth, and generate net profit. If your gross profit margin is shrinking over time, it may indicate rising production costs, pricing pressure, or inefficiencies in your supply chain.
Tracking gross profit margin regularly — and comparing it month-to-month or year-to-year — helps Australian business owners identify trends early, adjust pricing strategies, and make more informed operational decisions. It is also a key metric reviewed by lenders, accountants, and investors when assessing business health.
