Formula breakdown
Gross profit margin equals revenue minus cost of goods sold, divided by revenue. Net profit margin equals revenue minus all costs, divided by revenue. Markup compares profit to cost, while margin compares profit to price.
- Margin answers: how much of the selling price remains?
- Markup answers: how much did we add on top of cost?
- Net margin is the better whole-business health metric.
Industry benchmarks
Healthy margins vary by industry. Service businesses may run higher gross margins than retailers, while restaurants and product companies often watch inventory, labor, waste, and supplier pricing closely.
- Professional services often target higher gross margins.
- Retailers need tight inventory and markdown discipline.
- Software and digital products can show strong gross margins but still need operating expense control.
Ways to improve margins
Improve margin by raising prices carefully, reducing waste, renegotiating supplier terms, increasing average order value, packaging services, automating repetitive work, and discontinuing low-margin offers.
- Review your bottom 20 percent of products or clients.
- Track margin by offer, not only company-wide.
- Use pricing tests instead of guessing.

Frequently Asked Questions
What is a good profit margin for a small business?
It depends on the industry, but the trend matters as much as the benchmark. Compare by offer and watch whether margins improve over time.
What is the difference between margin and markup?
Margin is profit divided by selling price. Markup is profit divided by cost.
Should I track gross or net margin?
Track both. Gross margin shows delivery economics; net margin shows whether the whole business model works.
Can a business have high revenue and low profit?
Yes. Revenue can grow while profit shrinks if costs, discounts, labor, or overhead rise faster than sales.
How often should I calculate margin?
Monthly is a good baseline. Product-heavy businesses may review margins weekly.
