Pick and Pack Cost Calculator

Enter items per order and fees to find your pick-and-pack cost.

How it is calculated

The engine builds the order cost in two steps. First the labor: pick labor = base + (items − 1) × extra, where base is the fee that covers the first item and extra is the fee for every additional unit. Then cost per order = pick labor + materials, where materials is the packaging cost for the whole order (box, tape, void fill, label). Finally cost per item = cost per order ÷ items. If you leave base or extra blank the engine assumes 1.50 and 0.35; blank materials count as zero. Items must be at least 1. Amounts are shown in dollars, rounded to cents; use the same currency for every fee.

Worked example

An order of 3 items with a base fee of 2.50, an extra-item fee of 0.40 and 0.85 of packaging. Pick labor: 2.50 + (3 − 1) × 0.40 = 3.30, shown as $3.30. Add materials: 3.30 + 0.85 = $4.15 per order. Cost per item: 4.15 ÷ 3 = $1.38. Compare $4.15 with a 3PL quote for the same three-item order, remembering to check whether its quote includes packaging.

Common mistakes

  • Charging the base fee on every item. The base covers only the first item; the rest use the lower extra fee, and the formula multiplies the extra fee by items minus one.
  • Putting packaging cost per item into the materials box. It is a total for the whole order, so multiply first if you know a per-item figure.
  • Leaving base and extra empty and assuming they are zero; the engine silently fills in 1.50 and 0.35.
  • Comparing against a 3PL quote that excludes materials or receiving fees, so the totals are not like for like.
  • Entering a fractional average such as 2.5 items per order and expecting whole-order accuracy; use realistic single-order examples.

About this calculator

Pick-and-pack cost is the labor and materials expense a warehouse incurs to fulfill a single order, typically modeled as a base handling fee (covering picking the first item and packing the box) plus a per-extra-item fee for each additional SKU or unit, plus the cost of boxes, void fill, tape and labels. This calculator sums those three components to give a per-order fulfillment cost you can compare against what a 3PL charges or what you're actually spending in-house.

E-commerce sellers use it to check whether a third-party logistics provider's quote is competitive, while warehouse operations managers use the same breakdown to price internal fulfillment, set customer shipping thresholds, and spot line items — like packaging waste or excessive per-item fees on multi-SKU orders — that are eating into margin.

    Run the same fees at several basket sizes. With the default fees a one-item order costs 2.25 per item, while a five-item order costs 0.73 per item, because the base fee is spread across more units. That gap is what to compare when a third-party warehouse quotes by order rather than by item. What typical basket size do you ship?
