Order fulfillment cost per order is the total cost of picking, packing and shipping orders divided by the number of orders. Knowing it, and what it is made of, shows where the biggest savings are and what price or shipping fee covers your costs.

The formula
Cost per order = (labour + packaging + shipping + space + software and other + returns handling) / orders
Use a consistent period, such as one month, for all costs and for the order count. Allocate shared costs, such as rent for a warehouse that also stores stock for other uses, by a clear rule. If you offer free shipping, include the shipping cost you absorb, not the shipping fee you charge.
Worked example
5,000 orders a month with labour of $18,000, packaging of $6,000, shipping of $22,000, space of $9,000, software and other of $3,000 and returns of $2,000.
- Total cost = $60,000
- Cost per order = $60,000 / 5,000 = $12.00
- Shipping is the largest share at about 37%, then labour at 30%
Finding savings
Start with the largest items. Shipping can often be reduced by carrier negotiation, right-sized packaging and zone-aware warehouse placement. Labour cost depends on pick paths, batching and layout, which software and automation can improve. Look at cost per order alongside order accuracy and delivery time, since cutting cost at the expense of service is rarely a good trade.
Compare cost per order for different order profiles, such as single-item and multi-item orders, because averages hide them. See our warehouse and inventory guides and the pallet space calculator.
Common questions
What is a good cost per order?
There is no universal benchmark, because it varies with product size, order profile and shipping distance. Track your own trend over several months and compare against alternatives, such as a third-party logistics provider, using the same cost categories on both sides.
Should shipping be included in fulfillment cost?
Include the shipping you pay, net of what customers pay you, if you want the full cost to serve an order. Show it separately when you want to judge warehouse operations alone, since carrier rates and zones are driven by different factors than labour.
How can the result be compared with a 3PL quote?
Calculate your own figure with every category included, then compare it with the provider's total for the same volume: storage, receiving, pick and pack fees, packaging, returns and any minimums. Quotes that list only a pick fee understate the real cost.
How often should it be recalculated?
Monthly works for most operations, because it matches billing cycles and shows seasonal swings. Recalculate sooner after a change in carrier contract, layout, packaging or software, so you can see whether the change moved the number.
Why does cost per order rise when volume drops?
Part of the cost is fixed, mainly space, software and base staffing. When fewer orders share those costs, each order carries more of them. Look at the variable categories separately to tell volume effects from real efficiency problems.
