Formula: (Price - Cost) / Price × 100
Your profit margin tells you how much of every sale you actually keep. It's expressed as a percentage — and the higher it is, the more room you have to run ads, absorb refunds, and still turn a profit. For ecommerce and dropshipping store owners, understanding your margins is the difference between scaling a successful brand and running a charity.
The formula is straightforward: subtract your cost of goods sold from your selling price, divide by the selling price, and multiply by 100. If an item costs $100 and you sell it for $125, your gross profit is $25. Divide by $125, multiply by 100: you've got a 20% gross margin. That's the number to know before you set your price.
However, gross margin doesn't account for the hidden costs of doing business online. Customer acquisition cost (CAC), shipping fees, payment processor charges, and refund rates can quickly eat into your bottom line. This is why our calculator includes an optional CAC field — to give you a realistic view of your net profit margin. Always aim for a margin that allows you to reinvest in marketing while remaining profitable.
Let's explore some of the key terms you'll find in our profit margin calculator:
| Term | Definition |
|---|---|
| Revenue | What the customer pays (your selling price). |
| Cost of Goods Sold (COGS) | What you paid to source the product. |
| Gross Profit | Revenue minus cost of goods sold; also known as the operating profit. |
| Net Profit | What's left after all costs — COGS, shipping, ads, fees, etc. |
| Profitability | How well a product generates profit relative to its costs. |
| Markup | How much above cost you're charging, as a %. |
| Margin | The % of your selling price that's profit. |
A healthy dropshipping profit margin typically ranges between 15% and 30%. However, this can vary significantly based on your niche, average order value, and marketing costs. A 20% net margin is generally considered a solid benchmark for a sustainable dropshipping business.
Markup is the percentage difference between your cost and your selling price, calculated based on the cost. Profit margin is the percentage of the selling price that is profit. For example, if an item costs $10 and you sell it for $20, your markup is 100%, but your profit margin is 50%.
CAC is the cost of convincing a potential customer to buy your product (usually ad spend). It directly reduces your net profit. If your gross margin is 30% but your CAC eats up 20% of that, your net margin drops to 10%. Our calculator includes CAC to give you a realistic "net profit" figure.
Absolutely. While optimized for dropshipping and ecommerce, the core math behind profit margin is universal. Any business that buys a product at wholesale and sells it at retail can use this tool to determine their pricing strategy.
