How this calculator works
Profit can disappear when small transaction charges and acquisition costs are overlooked. This calculator provides a transparent per-sale contribution estimate and the price required to hit a target margin.
What the calculation does
Subtract product and fulfillment costs, fixed fees, ad spend, returns allowance, and the percentage-based processing fee from the selling price. Solve backwards for break-even and the requested target margin.
Important limitations
This is contribution profit per order, not accounting net profit. Taxes, overhead, advertising attribution, variable returns and marketplace-specific fees may require additional modeling.
Common questions
Is the profit after taxes?
No. This tool does not estimate sales tax, VAT or income tax.
Can I use any currency?
Yes. All amount inputs must use the same currency. Select the symbol for display only; no exchange-rate conversion occurs.
What if a target margin is impossible?
If target margin plus percentage transaction fees is 100% or more, no finite price reaches that target with positive fixed costs.
