About this calculator
This calculator is marketplace-agnostic: you enter your own prices, costs, and fees, and everything is computed in your browser. Nothing is sent to a server, and no live data or exchange rates are used.
How is this calculated?
Revenue = Selling price × Quantity
Percentage fees = Revenue × Fee % ÷ 100. Fixed fees = Fixed fee × Quantity.
Total cost = Product cost + Fulfillment + Fees + Advertising + Other costs
Gross profit = Revenue − Product cost
Net profit = Revenue − Total cost
Net profit margin = Net profit ÷ Revenue × 100
ROAS = Revenue ÷ Ad spend. ACoS = Ad spend ÷ Revenue × 100.
Break-even price = the selling price where net profit is zero, solved so that percentage-based fees are correctly included.
Understanding ecommerce profit
Ecommerce profit is what remains after every cost of selling a product is subtracted from the money you collect. It is easy to overestimate because small, recurring costs — payment fees, packaging, ad spend — add up per order.
Gross vs. net profit
Gross profit subtracts only the product cost, so it shows the raw markup on the item. Net profit subtracts everything else too, which is the number that tells you whether the sale actually makes money.
Which costs to include
Include product cost, shipping, packaging, other fulfillment, marketplace and payment fees, advertising, and any additional per-order costs. Fees can be a percentage of the sale or a fixed amount — the calculator supports both.
How advertising and break-even fit in
Advertising is a real per-order cost, and its effect is summarized by ROAS and ACoS. Your break-even selling price is the point where net profit reaches zero; pricing below it means each sale loses money once all costs are counted.
Frequently asked questions
What is an ecommerce profit calculator?
It is a tool that turns the economics of an order — selling price, product cost, fulfillment, fees, and advertising — into clear results like net profit, margin, and break-even price, so you can see whether a product is actually profitable.
How do I calculate ecommerce profit?
Start with revenue (selling price × quantity), then subtract every cost: product cost, shipping and packaging, marketplace and payment fees, advertising, and any other costs. What remains is your net profit.
What is the difference between gross and net profit?
Gross profit is revenue minus the product cost (cost of goods) only. Net profit subtracts all other costs too — fulfillment, fees, advertising, and other expenses — so it reflects what you actually keep.
What is a good ecommerce profit margin?
It depends heavily on your category, price point, and business model, so there is no single correct number. Use the calculator to compare scenarios and set a margin target that covers your overheads and leaves room to reinvest.
Does advertising affect ecommerce profit?
Yes. Advertising is a direct cost per order. This calculator lets you enter ad spend as a fixed amount per order or a percentage of revenue, and reports ROAS (revenue ÷ ad spend) and ACoS (ad spend ÷ revenue) so you can see the impact.
What costs should I include?
Include product cost, shipping, packaging, other fulfillment, marketplace/platform fees, payment processing fees, other transaction fees, advertising, and any additional per-order costs. Leaving costs out overstates your profit.
How do I calculate my break-even selling price?
Break-even is the selling price at which net profit equals zero. Because some fees are a percentage of the sale, it is not simply the sum of costs — the calculator solves for it while accounting for percentage-based fees and advertising.
