Profit Margin Calculator FAQs
What is profit margin?
Profit margin is the percentage of revenue that remains as profit after all costs are deducted. It shows how much money you actually keep from every dollar of sales. In ecommerce, knowing your profit margin helps you price products effectively and ensure your business stays profitable. High profit margins can give you more flexibility to invest in marketing, inventory, or growth, while low margins might mean you need to rethink your pricing or reduce costs.
How do you calculate profit margin?
To calculate profit margin, subtract the total cost of a product from its selling price. Then divide that number by the selling price and multiply by 100 to get a percentage. The formula looks like this: (Selling Price - Cost) ÷ Selling Price × 100 = Profit Margin. A higher percentage means you’re earning more per sale. It's important to include all costs, such as product manufacturing, shipping, transaction fees, and even marketing costs, for an accurate calculation.
How do you calculate gross profit margin?
Gross profit margin measures the amount of money left after covering the direct costs of making or sourcing your product, but before other business expenses like marketing or payroll. To calculate it, subtract the cost of goods sold (COGS) from total revenue, then divide that number by the total revenue and multiply by 100. Formula: (Revenue - COGS) ÷ Revenue × 100 = Gross Profit Margin. It shows how efficiently you produce or source your products.
What is gross profit margin?
Gross profit margin is the percentage of revenue that remains after deducting the cost of goods sold (COGS), such as manufacturing and shipping expenses. It does not account for other expenses like salaries, rent, or marketing. A higher gross profit margin indicates that a business is efficiently producing or sourcing products at a lower cost compared to their selling price, which can lead to stronger financial health if operating costs are well managed too.
What is net profit margin?
Net profit margin shows how much actual profit you make after all expenses are paid — not just the direct product costs, but also operating costs, taxes, loan interest, and marketing expenses. It’s calculated as (Net Income ÷ Revenue) × 100. Net profit margin provides the most complete view of your business’s profitability. Even if you have a high gross profit margin, a low net profit margin can signal that your operating expenses are too high and need attention.
What is a good profit margin?
A good profit margin varies by industry, but for ecommerce businesses, a typical range is between 20% and 50%. Higher-margin products like jewelry or beauty products can exceed 60%, while more competitive categories like electronics may operate with lower margins around 10%-20%. The “right” profit margin depends on your business goals, customer expectations, and how much value your product offers. Always aim for a margin that covers your costs and funds business growth.
Why is profit margin important for ecommerce stores?
Profit margin is critical for ecommerce stores because it determines how much money you actually make after covering costs. Understanding your margins helps you set profitable prices, withstand market fluctuations, offer discounts strategically, and reinvest in your business. If you’re not closely monitoring your profit margins, you risk selling products at a loss, especially after factoring in shipping, marketing, returns, and platform fees like Shopify, Amazon, or Etsy charges.
How can I improve my profit margin?
You can improve your profit margin by either increasing revenue or reducing costs — ideally both. Raise your prices where possible without hurting sales, find more cost-effective suppliers, negotiate better shipping rates, bundle products, or optimize your marketing spend to lower customer acquisition costs. Improving product pages to boost conversion rates and offering subscriptions or loyalty programs can also grow revenue per customer, lifting your margins without major cost increases.
What costs should I include when calculating profit margin?
When calculating profit margin, include all direct costs like the cost of goods sold (COGS), shipping, packaging, transaction fees, and any other variable costs tied to the product. For a more complete view, also consider overhead expenses such as salaries, rent, marketing, and software subscriptions. Leaving out hidden or overlooked costs can lead to inaccurate margins, causing you to underprice products and erode your profitability over time.
