Calculate net dropshipping profit, margin and break-even price with product, shipping, marketplace, payment, ads, returns, FX and fixed costs.
This is an independent technical guide and is not prepared, sponsored or approved by eBay, Shopify or Payoneer. Tax, company, customs and consumer-law obligations vary by country and business model. This section is not legal or tax advice.
The spread between selling price and supplier price is not real profit. This calculator combines product, shipping, marketplace, payment, ads, returns, FX and fixed operating costs. Fee rates remain user-entered because platform pricing changes by market, category, plan and provider.
Enter current official rates from your marketplace and payment provider.
Net contribution equals sale price minus product, shipping, percentage fees, fixed per-order fees and allocated monthly fixed costs.
eBay, Shopify and payment-provider fees can vary and change, so current official rates should be entered manually.
Use a percentage when you know ad cost as a share of revenue, or include per-order acquisition cost in fixed order cost.
A planning reserve helps model expected losses even when not every order is returned.
Margin alone does not describe cash flow; payout holds, supplier prepayment and refunds can create working-capital pressure.
Platform policies, payment methods and fees can change. Re-check the official sources below before taking action.
Use the current official fee pages for your marketplace, Shopify plan and payment provider.
You may model a reserve, but professional tax calculation depends on your jurisdiction.
