Shopify profit calculator for ecommerce stores
This Shopify Profit Calculator is for store owners who want to test whether a product can support paid traffic, shipping, packaging, and payment processing fees. It is useful for new product launches, ad testing, landing page pricing checks, and margin planning for direct-to-consumer brands.
How to use
Enter the selling price, product cost, shipping cost, transaction fee percentage, payment processing fee percentage, advertising cost, packaging cost, and other cost. The calculator estimates net profit, profit margin, ROI, total cost, and the break-even ROAS needed to stay profitable.
Formula
Total cost = product cost + shipping cost + transaction fees + payment processing fees + advertising cost + packaging cost + other cost. Net profit = selling price - total cost. Profit margin = net profit / selling price. ROI = net profit / total cost. Break-even ROAS = revenue / ad spend needed to cover the full cost structure.
Example
If a product sells for $59, costs $18 to source, $6 to ship, $12 to advertise, and another $3.50 to process and package, the calculator shows whether the product can survive paid acquisition and still leave room for discounting or returns.
Common mistakes
Common mistakes include ignoring shipping and packaging, using a target ROAS without checking total margin, and pricing products without enough room for refunds, fees, or higher acquisition costs during testing.
