Packaging cost per order is the direct cost of preparing one order for shipment. It should usually include materials and the labor required to pack the order, while keeping product cost and carrier charges separate.
Packaging cost formula
Add the unit cost of the box or mailer, filler, tape, labels, inserts and any other packaging consumables. Then add direct labor: packing minutes ÷ 60 × hourly labor cost. The Packaging Cost Calculator handles this breakdown.
Example: $0.85 box + $0.18 filler + $0.08 tape + $0.06 label + $0.05 insert = $1.22 materials. If packing takes 2.5 minutes at $18/hour, direct labor is $0.75. Total packaging cost becomes $1.97 per order.
Why this metric matters
A cheaper carton can create higher total cost if it takes longer to assemble, needs more void fill or increases shipping dimensional weight. Likewise, premium packaging may be justified when it reduces damage or supports a higher-value customer experience.
Compare packaging choices on total economics
For each candidate pack format, compare material cost, labor, packed dimensions and expected damage risk. Use the DIM Weight Calculator when changing carton size.
Track by order type
One average is not enough if your catalog varies widely. Group orders by box family, SKU combination or channel. High-cost outliers often reveal where packaging redesign has the fastest payback.
For broader ecommerce economics, pair this metric with shipping cost per order. Keeping packaging and transportation separate makes it easier to see whether an improvement came from warehouse operations or carrier spend.
Packaging-cost breakdown for a typical order
| Component | Example cost | Share of $1.97 total |
|---|---|---|
| Box or mailer | $0.85 | 43% |
| Filler, tape, label, insert | $0.37 | 19% |
| Direct packing labor | $0.75 | 38% |
This example shows why procurement alone cannot control packaging cost. Labor can be as important as the material itself, especially for low-value orders or complex presentation packaging.
Calculate the labor component consistently
Use productive packing time rather than a vague warehouse average. If a worker spends 2.5 minutes actually packing an order at an $18 hourly loaded labor cost, the direct packing component is $0.75. If a new carton saves 30 seconds, that labor effect can be compared directly with the material-price difference.
Where packaging cost usually hides
- Void fill used because cartons are too large
- Multiple labels or inserts added manually
- Slow box assembly
- Special tape or protective materials for fragile SKUs
- Packaging inventory write-offs after a redesign
- Higher carrier cost caused by oversized packaging

Frequently asked questions
Should I include warehouse overhead in packaging cost per order?
Not in a direct packaging metric unless that is your stated methodology. Keep rent, management and broad overhead separate so the packaging KPI remains actionable.
Should branded inserts count?
Yes if they are part of the pack-out and you want the true direct packaging cost. Keep them as a separate line so marketing can see their incremental cost.
How should I compare a mailer with a box?
Compare material cost, labor, packed dimensions and expected damage risk. Our mailer vs box guide provides the decision framework.
What is a good packaging cost per order?
There is no universal target. Product value, fragility, brand requirements and order profile differ. Benchmark your own order families and focus on avoidable cost.
