About this tool
Coupang RocketGrowth Simulator builds a monthly P&L for sellers using or evaluating Coupang RocketGrowth fulfillment. Inputs: monthly volume, selling price, COGS, average days-in-storage, box size, and the consolidated category fee (4~10.9%). The tool applies 2026 inbound (small 600 / mid 1,800 / large 3,500 / non-standard 5,250 KRW per box), outbound (1,800 KRW per order), and storage (120 KRW per box per month) โ then compares RocketGrowth net profit vs in-house seller-ship. Inventory turn โฅ2/mo = optimal, โค0.5 = loss alert. Best for standard boxes + โค30-day storage + โฅ100 orders/mo.
Use cases
Scenario 1
New-entrant simulation
A 200-orders/mo seller with mid box (1,800 inbound) / 15-day storage / 8% category sees a 300k/mo profit gap RocketGrowth vs in-house.
Scenario 2
Turn 0.5 loss alert
50/mo + 60-day storage = 0.83x turn; the tool flags a loss alert from storage burden.
Scenario 3
Non-standard large box
Non-standard >250cm or >30kg at 5,250 KRW inbound โ see margin compression and decide on switching to in-house.
Scenario 4
Category 4% vs 10.9% impact
Same SKU in 4% (Appliances) vs 10.9% (Fashion) categories โ compare monthly profit gap.
Scenario 5
Coupang 4-tool synergy
Combine with coupangfee (margin), coupangads (ROAS), and coupangsp (bidding) for an integrated revenue / ad / logistics decision.
