How the comparison works
- For each marketplace: (item price + local shipping) × exchange rate, plus the agent fee (China), weight (or volumetric weight, if larger) × rate per kg, and duty and VAT.
- For buying-agent orders, the US is duty-free up to 200 USD and others up to 150 USD.
- Profit is compared at the same price on Smart Store (Naver traffic, small-business tier) and Coupang (chosen category).
Exchange rates and per-kg shipping are examples. The closer they are to your real quotes, the more accurate the result.
