Revenue gets the attention, but profit margin is the number that tells you whether a business is actually healthy. You can be busy, grow sales, and still go backwards if your margin is too thin. Here is what margin means and what “good” looks like.
The three margins to know
- Gross margin is revenue minus the direct cost of what you sell, as a percentage of revenue. It tells you how much each sale contributes before overheads.
- Operating margin takes off your running costs (rent, software, salaries) too. It shows how well the core business runs.
- Net margin is what is left after everything, including tax and interest. It is your true bottom line.
So what is a good margin?
It depends heavily on your industry. A software business can run very high margins because it has low cost per sale. A retailer or a trade with lots of materials and labour runs much thinner. The honest answer is that “good” is relative to your sector, so the most useful comparison is against businesses like yours and against your own trend over time.
What matters more than a magic number:
- Is your margin stable or slipping? A falling margin is an early warning, even if sales are up.
- Do your prices keep pace with your costs? When suppliers or wages rise and your prices do not, your margin quietly erodes.
- Which products or services carry the business? Often a few high-margin lines subsidise the rest.
Work out your margin quickly
You do not need a spreadsheet to see where you stand. Our free profit margin calculator turns your cost and price into a clear margin figure so you can price with your eyes open.
Protect your margin with clean billing
Margin also leaks in the small stuff: unbilled expenses, forgotten costs, and slow payments that cost you in cash flow. Logging expenses against each job and billing them back, and getting paid on time, protects the margin you worked for. See how Billbooks helps small businesses keep the money side tight.
The short version
- Know your three margins: gross, operating, net.
- “Good” is relative to your industry and your own trend.
- Watch the trend, not just the number.
- Keep prices in step with costs, and bill every expense.
Margin is the number that quietly decides whether a business lasts. Check it often.
