What Is Pick-and-Pack Cost?
Pick-and-pack cost is the cost of finding items in inventory, preparing an order, and packing it for shipment, excluding postage. It includes labor, packaging materials, the expected cost of packing errors, and an allocated share of warehouse overhead.
Tracking cost per order helps you compare fulfillment methods and spot expenses that can shrink your margin. For postage by destination, use the Shipping Cost Calculator (Zone-Based); for a broader comparison of outsourced fulfillment expenses, use the 3PL Cost Calculator.
Pick-and-Pack Cost Formulas
Labor cost per order = Hourly labor rate ÷ Orders packed per hour
Materials cost per order =
Box or mailer cost + Void fill + Tape and labels
+ (Custom insert cost × Insert percentage)
Expected QC cost per order =
QC error rate × Rework cost per order
Overhead per order =
(Monthly rent per sq ft × Packing area sq ft + Monthly equipment cost)
÷ Monthly orders
Pick-and-pack cost per order =
Labor + Materials + Expected QC cost + Overhead
Enter the QC error rate and insert percentage as decimals in the calculations: for example, 2% becomes 0.02. This estimate allocates the stated packing area and equipment costs across monthly orders; it does not include postage, storage outside that area, or other overhead you have not entered.
How to Use This Calculator
- Enter Monthly Orders to allocate monthly rent and equipment costs across your expected fulfillment volume.
- Enter Avg Items per Order and Avg Order Value. Item count describes order complexity, while order value lets you compare fulfillment cost with sales revenue.
- Enter Labor Rate as the hourly cost of warehouse staff, including benefits, and Orders per Hour as the number one worker completes. Employer labor costs can include more than wages; the Bureau of Labor Statistics’ compensation data tracks wages and benefits separately.
- Enter Box Cost, Void Fill, and Tape/Labels Cost as average per-order material expenses. Use the USPS packaging guidance to review package preparation requirements for USPS shipments.
- Enter Custom Insert Cost and Insert Pct to account for inserts only on the share of orders that receive them.
- Enter QC Error Rate and Rework Cost per Order to estimate the expected cost of incorrect orders, including the labor and reshipping needed to fix them.
- Enter Rent per Sq Ft, Packing Area Sq Ft, and Equipment Monthly to allocate packing-area rent and equipment costs across orders. Change an input to compare the resulting cost and optimization potential.
Step-by-Step Example
Suppose a Shopify store packs 800 orders per month. Its average order contains 2.3 items, and its average order value is $55.
| Cost component | Calculation | Cost per order |
|---|---|---|
| Labor | $18 ÷ 25 orders per hour | $0.72 |
| Box or mailer | Entered average | $1.10 |
| Void fill | Entered average | $0.35 |
| Tape and labels | Entered average | $0.25 |
| Custom inserts | $0.40 × 100% of orders | $0.40 |
| QC rework | 2% × $12 | $0.24 |
| Rent | ($1.25 × 400 sq ft) ÷ 800 orders | $0.63 |
| Equipment | $150 ÷ 800 orders | $0.19 |
| Total | Add all per-order costs | $3.88 |
The unrounded total is $3.8725 per order. Monthly pick-and-pack cost is $3.8725 × 800 = $3,098, and the cost is $3.8725 ÷ $55 × 100 = 7.0% of order revenue. Postage is not included.
What Drives the Cost—and When to Outsource
Labor efficiency and materials are often the largest costs a store can change directly. Faster packing lowers labor cost per order, while choosing packaging that safely fits the product can reduce material expense and packing time. Packaging also affects billed postage: compare package dimensions with the Dimensional Weight Calculator before changing box sizes.
The result is a starting point for comparing in-house fulfillment with a 3PL, not a complete outsourcing quote. A 3PL may add receiving, storage, account fees, or other charges, while an in-house estimate may omit supervision, utilities, or space used outside the packing area. Compare equivalent services and include all recurring charges before switching.
For manual packing stations, layout affects both speed and worker strain. OSHA’s ergonomics guidance covers workplace factors that can contribute to musculoskeletal disorders; keep frequently used supplies within easy reach and assess repetitive tasks as you redesign a station.
Pick-and-Pack Benchmarks
Use these ranges as planning references, then compare them with your own order mix, packaging choices, and service requirements.
| Measure | Planning benchmark | How to interpret it |
|---|---|---|
| In-house pick-and-pack | $2–$6 per order | Excludes postage; multi-item orders can require more work. |
| 3PL pick-and-pack | $3–$8 per order | Check what the provider includes and what it bills separately. |
| Packer throughput | 20–35 single-item or 15–25 multi-item orders per hour | Batch picking, scanning, layout, and packaging complexity affect speed. |
| Pick-and-pack as share of revenue | Under 5–8% | A lower percentage generally leaves more revenue for product and operating costs. |
| Picking and packing error rate | Under 1% | Track errors alongside rework and reshipping expense. |
Cost per order alone can mislead: a higher-cost service may include labor or packaging that your own estimate excludes. For products with bulky packaging, review shipping dimensions as well as handling cost.
6 Tips to Reduce Pick-and-Pack Cost
- Test a faster station layout: Change the placement of your most-used mailers and tape so packers do not need to walk for supplies; compare orders per hour before and after.
- Separate single-item orders: Batch-pick simple orders separately from complex ones, then compare labor time for each group rather than averaging unlike workflows.
- Audit packaging by product: Test a mailer for a durable garment and a box for a fragile item. EPA’s sustainable packaging guidance can help you evaluate packaging choices alongside material use.
- Review insert coverage: Change an insert policy from every order to only repeat-customer or campaign orders, then calculate the material savings against the marketing purpose.
- Track rework by cause: Record whether each error came from a wrong item, quantity, or label; target the most frequent cause instead of applying a general fix.
- Compare free-shipping thresholds with fulfillment economics: Test a higher minimum order value using the Free Shipping Threshold Optimizer, and check whether the extra basket revenue offsets the shipping offer.
Frequently Asked Questions
How much does pick and pack cost per order?
Pick and pack typically costs $2–$6 per order in-house and $3–$8 through a 3PL, excluding postage in many comparisons. Labor commonly accounts for $0.50–$1.50, while boxes or mailers, void fill, tape and labels, and inserts make up the materials cost; multi-item orders and allocated overhead can raise the total.
How many orders can one person pack per hour?
A trained packer typically completes 20–35 single-item orders per hour or 15–25 multi-item orders per hour, with optimized operations sometimes exceeding 40. Batch picking, barcode scanning, warehouse layout, and packaging complexity all affect throughput, so use your own measured rate when estimating labor cost.
What percentage of revenue should pick and pack cost?
Pick and pack, excluding shipping, is commonly targeted below 5–8% of revenue; above 10% can indicate low average order value or an inefficient process. Compare the percentage by product category and order type, since a low-priced item can carry a high fulfillment-cost share even when its per-order cost is ordinary.
How do I reduce pick and pack errors?
Barcode scanning, photo verification, pick-to-light systems, clear pick lists, and daily quality spot checks can help prevent errors. An error rate under 1% is a useful benchmark, but measure the full cost of each mistake—including re-picking, repacking, reshipping, and customer service time—when prioritizing fixes.
Should I use poly mailers or boxes?
Poly mailers are generally less expensive and faster to pack, making them suitable for soft goods, clothing, accessories, and small flat items that do not need rigid protection. Use boxes for fragile products, multi-item orders, or goods that need more protection, and check carrier packaging rules for the service you use.
