Example calculation
What is a good net profit margin?
Net profit margin is one of the most important financial metrics because it measures how much of your revenue becomes actual profit after every expense has been paid.

Your business has little room for unexpected expenses. Improving pricing or reducing costs should be a priority.

The business is profitable, but improving operational efficiency could significantly increase earnings.
Strong
A healthy net profit margin for many ecommerce businesses, providing room for sustainable growth.

- Net profit reflects the real money your business earns.
- Healthy net margins provide cash for growth, hiring and marketing.
- Monitoring net profit over time is more useful than reviewing a single month.
- MarginLab automatically tracks profit trends across every product and order.
Common net profit mistakes
Net profit is often lower than expected because businesses forget to include all real expenses. These are the most common mistakes when calculating net profit.
Ignoring operating expenses
Rent, salaries, software, marketing and admin costs all reduce net profit and must be included in the calculation.
Forgetting refunds
Refunds directly reduce revenue and profit. Excluding them can make your business look more profitable than it really is.
Underestimating shipping costs
Shipping, fulfillment and packaging can significantly reduce net profit, especially on low-priced or heavy products.
Using incomplete product costs
If product costs are missing or outdated, your net profit calculation becomes unreliable.
Why net profit matters for Shopify stores
Revenue alone doesn’t tell you whether your Shopify store is actually making money. Net profit reveals what remains after product costs, operating expenses, discounts, refunds and shipping have all been deducted.
What reduces net profit?
- Operating expenses continue to grow as the business scales.
- Refunds and discounts reduce the final amount you keep.
- Shipping and fulfillment costs are often underestimated.
- Marketing costs can absorb a large share of revenue.
- Small profit leaks across many orders quickly become significant.
