How this calculator works
Revenue is the selling price. Percentage fees are applied to the selling price, then the fixed fee is added. Net profit = revenue − product − outbound shipping − packaging − advertising − other costs − platform/payment fees. Margin = profit ÷ revenue × 100. ROI = profit ÷ estimated costs × 100.
A $50 order with $18 product cost, $5 shipping, $2 packaging, $3 advertising, 10% platform fees, 3% payment fees and $0.30 fixed fees yields $15.20 estimated profit and 30.4% net margin.
Assumptions and limitations
All amounts must use the same currency. This model excludes taxes, currency-conversion charges, refunds and seller-specific fee rules unless you include them in other costs. Use the appropriate rates for your marketplace.
Frequently asked questions
Does this calculate net profit?
It estimates profit per order after the inputs you enter. Business overhead and taxes are not included unless you add them to other costs.
Can I use AED or INR instead of USD?
Yes. Enter every amount in the same currency; the on-screen dollar symbol is only the default display label. Currency conversion is not performed.
