3PL Cost Calculator

Pick-pack fees are only the visible part of the 3PL stack. Use this calculator to allocate storage, receiving, packaging, and postage across monthly order volume so the real fulfilment burden per order stops hiding in separate invoices.

Calculate 3PL cost

Enter monthly order volume, average items per order, pick-pack pricing, packaging, monthly storage, receiving, and average postage. The result shows what the 3PL really costs once fixed overhead is spread across the flow.

Monthly orders Needed to allocate storage and receiving per order. Average items per order Used for extra-item drag and cost per unit shipped. Pick fee per order Base pick-pack charge for the order. Additional item fee Applied to each item after the first one. Packaging cost per order Packaging, dunnage, or order materials cost. Storage cost per month Monthly storage invoice allocated across order volume. Receiving cost per month Monthly inbound receiving or check-in cost. Postage cost per order Average outbound postage or linehaul cost.

Three 3PL operating scenarios.

Formula

What the 3PL model includes

3PL cost per order = Pick-pack + Packaging + Postage + ((Storage + Receiving) / Monthly orders)

The point of this model is to stop treating storage and receiving as “background” charges that sit outside the order. If they are necessary to move the item, they belong inside the order economics when you judge margin, payout, and ROAS.

Where 3PL costs get misread

Low order volume makes storage and receiving much heavier per order.
Extra-item fees quietly punish multi-unit baskets.
Postage and packaging often get tracked outside the channel economics.

Useful next step

Once fulfilment is cleaned up, connect it back to landed cost, payout margin, and break-even ROAS to see whether the product can still support traffic profitably.
