A Shopify profit calculator is a free ecommerce profit calculator that shows your real profit per order after every cost: product cost (COGS), shipping, payment processing fees, discounts, refunds, fixed overhead and advertising. Instead of guessing your margin, this product profit calculator gives you a clear, currency-formatted breakdown so you can price products and scale paid ads with confidence.
Start with your selling price, subtract discounts to get revenue after discount, then account for refunds to find expected revenue. Subtract product cost, shipping, payment fees and your share of monthly fixed costs to get profit before ads. Finally subtract your ad spend per order (CPA). What remains is your true net profit per order. This ecommerce profit calculator automates the entire flow.
Break-even ROAS is the return on ad spend at which you make zero profit on an order, after all non-ad costs. With this break-even ROAS calculator it is revenue after discount divided by your maximum CPA. If your campaigns run above break-even ROAS you are profitable; below it you are losing money on every sale.
Maximum CPA is the most you can spend to acquire a single order while still breaking even. Use this max CPA calculator value as a hard ceiling for your cost per acquisition targets in Meta, Google or TikTok ads. Spend less than your max CPA and every order is profitable.
Many founders calculate margin on the full selling price and forget that discounts reduce revenue, refunds erase entire orders, and payment processors take a percentage plus a fixed fee on every transaction. Ignoring these makes your Shopify margin calculator estimates dangerously optimistic. Including them reveals your true contribution margin.
Pricing on gross margin instead of net margin, ignoring fixed costs per order, forgetting payment fees, underestimating refund rates, and scaling ad spend above break-even ROAS are the most common ways stores lose money while appearing to grow. Always validate unit economics with an ecommerce ROAS calculator before increasing budgets.
This calculator provides educational estimates only and is not financial advice. Always validate figures with your own accounting and consult a qualified professional before making business decisions.
Healthy Shopify stores typically aim for a net margin of 15–30% after all costs including ads. Dropshipping stores often run thinner margins and rely on volume, while branded or private-label stores can exceed 30%.
Divide your revenue after discount by your maximum CPA (your profit before advertising). The result is the ROAS at which you neither make nor lose money. This tool computes it automatically.
Yes. Shipping and fulfillment are real per-order costs. Leaving them out inflates your margin and can lead you to overspend on ads.
Absolutely. A 5% refund rate means roughly 5% of your revenue disappears. Modeling refunds gives you a realistic expected revenue per order.
Maximum CPA is the highest amount you can pay to acquire an order while still breaking even. Keep your real CPA below this number to stay profitable.
No. While built around the Shopify cost structure, it works for any ecommerce platform such as WooCommerce, BigCommerce, or your own store.
It includes payment processing fees (percentage plus a fixed fee) which cover Shopify Payments-style charges. You can also fold subscription costs into your monthly fixed costs.
Yes. Enter your supplier product cost and shipping as your COGS and fulfillment, and the calculator will show your real dropshipping profit and break-even ROAS.
