The three numbers that drive your cost
For most ecommerce brands using KAK, monthly fulfillment cost breaks down to three line items:
- FBA prep: units prepped/month × $0.75/unit. If you prep 2,000 units/month for Amazon FBA = $1,500.
- FBM orders: orders shipped/month × $2.00/order. 500 FBM orders/month = $1,000. Postage is at cost on top, typically $4–7/order for 1lb items at zone 4 average.
- Storage: pallets stored × $25/month. 10 pallets in storage = $3,000/year, or $250/month.
Worked example
Mid-size ecommerce brand: 3,000 FBA units/month + 800 FBM orders/month + 12 pallets average inventory.
FBA prep: 3,000 × $0.75 = $2,250. FBM pick-pack: 800 × $2.00 = $1,600 + ~$3,500 postage at cost = $5,100. Storage: 12 × $25 = $300/month. Total monthly: ~$7,650. That’s everything — no setup fee, no monthly platform fee, no surcharges.
What other 3PLs charge for the same volume
Typical US 3PL pricing for the same brand: FBA prep at $1.30–1.80/unit (per-step) = $3,900–5,400. FBM at $3.50–5/order + postage = $6,300–7,500. Storage at $35–50/pallet/month = $420–600. Plus account-management fees, peak-season multipliers, fuel surcharges. Easily $11,500–14,500/month.
