Is your Shopify product actually leaving you a healthy margin? Check it below.
Profit margin is what's left as a percentage of the sale price after every cost — and on Shopify the processing fee quietly eats into it on every order. Enter your price, product cost, and shipping, pick your plan, and the calculator shows your margin % per sale after Shopify's fee. A product that looks profitable on revenue can have a thin real margin once the fee and cost of goods come out.
This free calculator shows your net profit per sale on one product. The full Shopify Profit Calculator compares all 5 plans side by side, models third-party gateways, runs your whole catalog via bulk CSV, and shows ROI, break-even, and a fee breakdown chart — 100% offline, one-time purchase, no subscription, no login.

Most Shopify sellers track gross margin. Here's why that number is dangerously misleading.
Shopify's analytics subtract only your product cost from revenue. They don't include platform fees, payment processing, refunds, or ad spend.
True net margin subtracts everything: COGS, all Shopify fees, shipping, fulfillment, refunds, ad spend, and prorated plan cost. This is what you actually keep.

Questions
15–20% net margin is considered healthy for most Shopify merchants. Under 10% is risky — one fee change or ad cost increase can eliminate profitability. Above 25% provides strong scaling potential.
