What will you actually keep? Net margin calculator
Net profit = order revenue − platform fees − payment fees − currency conversion − product and logistics costs − expected returns and chargeback losses − advertising. Most sellers overestimate margin because they skip the last three. Enter your order economics below; the breakdown shows exactly where each dollar goes.
You keep ≈ USD 11.03 per order (27.58% effective margin).

What changes this answer
- Return rate is usually the biggest hidden lever — a few points move net margin fast.
- Charging separately for shipping shifts fee base on most platforms (fees apply to shipping too).
- Cross-border currency conversion applies to the whole order, not just your margin.
The costs sellers most often forget
Three costs are missing from most margin spreadsheets: currency conversion (charged on the whole order, not your profit), expected return losses (rate × average loss, including outbound shipping you never recover), and chargebacks (fee plus lost goods).
Fees also apply to the shipping you charge the buyer on most platforms, so 'free shipping built into price' versus 'separate shipping line' changes your fee base, not just your conversion rate.
Common questions
- Should I use average or worst-case return rates?
- Use your trailing average per market. Cross-border apparel returns often run far higher than domestic; the expected-loss line scales linearly with the rate, so test both.
