Packing is one of the final steps in the fulfillment process and a significant cost driver for ecommerce and direct-to-consumer operations. The total packing cost per order includes four components: labor (time to pack each order), box or packaging material, dunnage (void fill, bubble wrap, paper), and labels (shipping label, packing slip, return label).
This calculator sums these four components to produce a per-order packing cost. Knowing this number helps you benchmark against industry averages ($1.50-$4.00 per order for typical ecommerce), identify the largest cost drivers, and prioritize efficiency improvements like right-sized boxing, automated label application, or ergonomic station design.
Use This calculator when evaluating packing station productivity, comparing in-house versus 3PL fulfillment costs, or budgeting for new automation like auto-boxers or auto-baggers.
Use the result to compare operating scenarios, pressure-test assumptions, and rerun the model when volumes, rates, or service targets change.
Packing costs are often lumped into a general fulfillment cost per order, obscuring opportunities for improvement. By breaking the cost into labor, material, dunnage, and labels, you can see exactly where to focus. Reducing packing time by 30 seconds per order across 5,000 orders/day saves significant labor annually.
Packing Cost per Order = Labor + Material + Dunnage + Labels
Daily Packing Cost = Cost per Order รโ Daily Orders
Annual Packing Cost = Daily Cost รโ Working DaysResult: $2.60 per order ($7,800/day)
Per order = $1.25 + $0.85 + $0.35 + $0.15 = $2.60. Daily = $2.60 รโ 3,000 = $7,800. Annual (250 days) = $1,950,000. Labor represents 48% of the packing cost, making it the top optimization target.
Labor is typically the largest component at 40-55% of packing cost, followed by packaging material (25-35%), dunnage (10-20%), and labels (5-10%). The exact split varies by product type, packaging complexity, and automation level.
An ergonomic packing station puts all materials within arm's reach, uses adjustable-height surfaces, provides good lighting, and minimizes reaching and bending. Each second saved per order compounds dramatically at high volumes. Industrial engineering principles applied to packing stations yield 15-25% productivity gains.
Auto-boxers measure products and create fitted boxes in seconds, eliminating dunnage entirely. Auto-baggers seal poly mailers at speeds of 1,000+ per hour. Automated label print-and-apply systems eliminate manual label handling. Each technology targets a specific cost component and typically pays for itself in 6-18 months at high volumes.

For typical ecommerce operations, packing costs range from $1.50-$4.00 per order. Subscription boxes and gift packaging can run $3.00-$8.00+. High-volume, standardized operations may achieve under $1.50.
Divide the packer's hourly rate by their orders-per-hour rate. If a packer earns $18/hour and packs 30 orders/hour, the labor cost is $18 / 30 = $0.60 per order. Include benefits in the hourly rate for fully loaded cost.
Dunnage is the protective fill material placed inside a box to prevent product damage. Common types include air pillows, kraft paper, bubble wrap, foam peanuts, and molded inserts. Cost varies from $0.10-$1.00+ per order.
Use right-sized boxes to minimize void space, invest in auto-sizing carton machines, switch to lower-cost void fill (kraft paper versus bubble wrap), and evaluate whether some products need dunnage at all. Consult a professional for advice tailored to your specific situation.
Poly bags cost $0.10-$0.30 and require no dunnage for soft goods. They are appropriate for clothing, textiles, and flexible items. Boxes are required for fragile, rigid, or heavy items. A mixed approach optimizes both cost and protection.
Simple single-item orders can be packed at 40-80 per hour. Multi-item orders with dunnage typically run 20-40 per hour. Automated stations can achieve 100-200+ per hour depending on complexity.
