Watch how the orange placement block shrinks as destinations increase while freight and handling grow — the cheapest option is wherever the stack is shortest.

A lower destination count can simplify an inbound shipment but may add a per-unit placement fee. Sending to more Amazon-assigned locations may reduce placement charges while increasing freight, labels, appointments, and handling.
The cheapest choice is the combined cost—not the option with the lowest placement fee or carrier quote in isolation.
Use the fee estimate shown while creating the shipping plan and obtain carrier quotes for the exact destinations. Include pallet preparation, carton labels, pickup minimums, liftgate charges, residential surcharges, and prep-center labor where applicable.
Destination availability and fees can change between plans, so save the assumptions used for each decision.
For each option, total cost equals placement fees plus transportation plus incremental handling for additional destinations. Cost per unit is the total divided by units shipped.
The model does not account for receiving-speed differences, inventory availability, shipment defects, or the operational value of simplicity. Use the lowest-cost result as a starting point.
When you build a shipping plan in Send to Amazon, the placement choices boil down to a trade: fewer destinations means Amazon does the redistribution (and charges you per unit for it); more destinations means you do the splitting and pay the freight. Each option tends to win in a different situation:
| Option | What it means | Placement fee | When it usually wins |
|---|---|---|---|
| Minimal split | Everything goes to one (sometimes two) Amazon-chosen locations; Amazon redistributes internally. | Highest per-unit fee | Small shipments, heavy or bulky items where extra freight legs are expensive, and sellers shipping direct from a factory who can't easily split cartons. |
| Partial split | You split across a middle number of destinations (typically 2–3). | Reduced per-unit fee | Mid-size shipments where one extra freight leg is cheap but four aren't — often the quiet winner, as in this tool's default numbers. |
| Amazon-optimized split | You ship to the full set of Amazon-assigned destinations (often 4+). | Often $0 | Large, light, high-unit-count shipments where the avoided fee (units × fee) dwarfs the extra freight — e.g. 5,000 units at $0.30 is $1,500 of avoided fees. |
The structure of the decision: placement fees scale with units, freight scales with shipments. Small shipment → pay the fee. Large shipment → do the split. The crossover point is exactly what this calculator finds for your numbers.
Using this tool's default inputs — 1,000 units, $0.50/unit minimal placement fee, $0.25/unit partial fee, and freight quotes of $450 / $650 / $900 with $35 handling per extra destination:
| Option | Placement | Freight | Handling | Total | Per unit |
|---|---|---|---|---|---|
| Minimal split (1 dest.) | $500 | $450 | $0 | $950 | $0.95 |
| Partial split (2 dest.) | $250 | $650 | $35 | $935 | $0.94 |
| Optimized split (4 dest.) | $0 | $900 | $105 | $1,005 | $1.01 |
Three lessons hide in this table. The spread between best and worst is only $70 — at this shipment size the decision barely matters, and taking the operationally simplest option is defensible. Double the units to 2,000, though, and the minimal option's placement fee doubles to $1,000 while freight barely moves — suddenly the optimized split wins by hundreds of dollars. And the "free" optimized option was never free: $205 of freight and handling replaced $250 of fees.
The comparison is only as good as its inputs, and several real costs routinely get left out of the freight quote:
If two options land within a few percent of each other, choose on operations — receiving speed and simplicity — rather than the modeled dollar difference.
Use the estimate Amazon displays for each available placement option while building the inbound plan.
Some qualifying Amazon-optimized shipment configurations may show no placement fee; use the actual options presented to your shipment.
No. It compares the costs of options Amazon makes available; it does not create or transmit a shipment.
They vary by size tier, weight, destination region, and the option you choose — typically a per-unit charge for minimal and partial splits, and often $0 for the Amazon-optimized split. Always use the exact per-unit estimates shown in your own shipping plan, since published rates change and your items' size tier drives the number.
Small shipments (roughly under a few hundred units), heavy or oversized items where each extra freight leg is expensive, and factory-direct shipments that are impractical to split. The fee scales with units, so the fewer units you send, the cheaper 'let Amazon redistribute' becomes.
Often yes — stock lands closer to buyers in multiple regions and check-in happens in parallel, so a backlog at one fulfillment center doesn't strand the whole replenishment. That availability benefit isn't in the cost model, and it's a legitimate reason to pick a slightly more expensive split before peak season.
