Pick-and-pack is the core warehouse fulfillment operation: picking items from storage locations and packing them into shipping containers for outbound delivery. A pick-pack cost calculator helps warehouse managers, e-commerce fulfillment directors, and operations teams measure the true cost per order of fulfillment operations, identify efficiency improvement opportunities, and benchmark performance against industry standards. Pick-pack cost has two primary components: picking cost (labor time to travel to each storage location and retrieve the item) and packing cost (labor time to verify, pack, label, and stage for shipment). Pick-pack also includes indirect costs: paper/packaging materials, packing supplies (bubble wrap, void fill, tape), carton costs, and a share of warehouse overhead. In e-commerce, pick-pack is typically the largest variable cost component of fulfillment after outbound shipping — averaging $2.50–$6.00 per order for most operations. Key productivity metrics are picks per man-hour (typically 60–150 in manual operations, 300–500 in voice-directed or RF-scanning operations, 600–2,000 in goods-to-person automated systems) and cost per pick. The calculator helps evaluate the ROI of technology investments: would adding voice picking or conveyor sortation reduce cost per pick enough to justify the capital expenditure?
Cost per Order = (Pick Labor Cost + Pack Labor Cost + Material Cost) / Orders Shipped Pick Labor Cost = (Orders × Lines per Order × Pick Time per Line × Labor Rate) / 60 Pack Labor Cost = Orders × Pack Time per Order × Labor Rate / 60 Picks per Man-Hour = Total Picks / Total Labor Hours Material Cost per Order = Carton Cost + Void Fill + Tape + Label + Packing Slip Total Pick-Pack Cost = Labor (pick + pack) + Materials + Overhead Share
- 1Enter daily or monthly order volume and average lines (SKUs) per order.
- 2Input average pick time per line in seconds: travel + locate + pick + scan (typically 20–45 seconds in manual operations).
- 3Input average pack time per order in minutes: verify, pack, label, seal, stage (typically 2–5 minutes).
- 4Enter labor rate (fully loaded: wage + benefits + supervision overhead).
- 5Add material costs per order: carton cost ($0.30–$2.00), void fill ($0.15–$0.60), tape, label, packing slip.
- 6Add warehouse overhead allocation per order (facility, equipment, WMS amortization).
- 7Sum all components and divide by orders to get total pick-pack cost per order.
At $3.33/order, daily fulfillment cost is $999. 103 picks/hour is decent for a manual paper-pick operation. Voice-directed picking could improve to 140+ picks/hour, saving $0.75/order ($225/day).
B2B orders with 8.5 lines per order are significantly more labor-intensive. High pick time investment per order means batch picking strategies (pick all orders for one SKU simultaneously) can dramatically reduce travel time.
Voice picking increases productivity 52.6%, saving $183/day. Against $24K annual system cost, the net benefit is $24K/year — a 30-month payback. Error reduction (1.5% to 0.3%) adds additional $40K in avoided return costs annually.
Very close economics — 3PL is marginally cheaper at this volume. At 2,000+ orders/day, in-house scales better. At lower volumes, 3PL's fixed-cost avoidance advantage grows significantly.

In the Pick Pack Cost Calc, this scenario requires additional caution when interpreting pick pack cost results. The standard formula may not fully account for all factors present in this edge case, and supplementary analysis or expert consultation may be warranted. Professional best practice involves documenting assumptions, running sensitivity analyses, and cross-referencing results with alternative methods when pick pack cost calculations fall into non-standard territory.
{'case': 'Kitting and Assembly', 'note': "Orders requiring assembly (kit building, gift wrapping, custom configuration) add $1–10+ per order in labor. Kitting stations should be purpose-designed with all components within arm's reach (lean 5S principles), reducing kit assembly time by 30–50%."}.

Conduct a 30-minute time study on 10 random orders being picked and packed. Break each into 5-second increments: travel, locate, reach, grasp, place, scan, move to next. You'll discover that 50–65% of pick time is travel — the single biggest improvement opportunity, addressable through slotting, zone design, and batch picking before any technology investment.

Amazon's fulfillment centers process over 1 million orders per day during peak season. Their Kiva robot systems (now Amazon Robotics) reduce pick-pack time by approximately 40% compared to traditional picking — saving Amazon an estimated $916 million annually in fulfillment labor costs. When Amazon acquired Kiva Systems in 2012 for $775M, it paid back the investment in under 1 year.
