Do not apply one fee rate
The Coupang result varies by category, market, campaign and service. Use the actual deduction line and divide it by the matching sales base.
This produces an effective period fee that can be compared with plan and prior periods.
Separate deductions by cause
Account for fulfillment: inventory is separated across Rocket Growth, Coupang warehouses and seller fulfillment. It changes logistics, storage and return-related lines.
- selling fee
- handling, delivery and reverse logistics
- storage, receiving and optional services
- penalties, reimbursements and adjustments
Compare like-for-like conditions
The Coupang focus includes broad catalog, Rocket delivery, fast turnover and local order economics. Compare SKUs within the same category, market and fulfillment model.
A higher deduction share may come from price, returns, dimensions or paid-service usage rather than a rate change.
