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 × $1/unit. If you prep 2,000 units/month for Amazon FBA = $2,000.
FBM orders: orders shipped/month × $2.75/order. 500 FBM orders/month = $1,375. Postage is at cost on top, typically $4–7/order for 1lb items at zone 4 average.
Storage: pallets stored × $25 × 26 biweekly cycles. 10 pallets in storage = $6,500/year, or ~$542/month.

Worked example

Mid-size ecommerce brand: 3,000 FBA units/month + 800 FBM orders/month + 12 pallets average inventory.

FBA prep: 3,000 × $1 = $3,000. FBM pick-pack: 800 × $2.75 = $2,200 + ~$3,500 postage at cost = $5,700. Storage: 12 × $25 × 26 / 12 = $650/month. Total monthly: ~$9,350. 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.
