Order Fulfillment Cost Calculator
Calculate the true total cost to fulfill a single customer order, covering labor, packaging, shipping, and overhead. Use it to set profitable pricing or benchmark fulfillment efficiency.
About this calculator
The total cost to fulfill one order has four components: the labor cost of picking items from shelves, the materials and labor cost of packing and boxing them, the carrier shipping charge, and a share of warehouse overhead allocated as a percentage of order value. The formula is: Total Cost = pickingCost + packingCost + shippingCost + (orderValue × overheadRate). The overhead rate is expressed as a decimal (e.g., 0.05 for 5%) and captures rent, utilities, management salaries, and technology costs spread across all orders. Understanding this number helps e-commerce and 3PL operators identify which cost driver—labor, materials, or overhead—has the biggest impact on margin. Benchmarks suggest a healthy cost-to-order-value ratio is below 15–20% for most e-commerce operations.
How to use
Imagine an order with a $45 average order value. Picking labor costs $1.20, packing and box materials cost $0.80, and the average shipping cost is $6.50. The warehouse overhead allocation rate is 8% (0.08). Total Cost = $1.20 + $0.80 + $6.50 + ($45 × 0.08) Total Cost = $8.50 + $3.60 = $12.10 This means fulfilling each order costs $12.10, or about 26.9% of the order value. If your gross margin is below that, you are losing money on fulfillment. Adjust the overhead rate or shipping cost to model improvements.
Frequently asked questions
What is a good cost per order for e-commerce fulfillment?
Industry benchmarks vary by sector, but most e-commerce businesses aim for a fulfillment cost between $3 and $10 per order excluding shipping, and a total fulfillment-to-revenue ratio below 15–20%. High-SKU, low-weight products like apparel tend to sit at the lower end, while bulky or fragile items drive costs higher. Third-party logistics (3PL) providers typically charge $2–$5 for pick-and-pack plus materials. Regularly recalculating your cost per order helps you spot when labor rates or packaging costs are eroding margins.
How should I calculate the overhead allocation rate for fulfillment?
Divide your total annual warehouse overhead (rent, utilities, equipment depreciation, management salaries, WMS software) by your total annual order revenue or order volume. For example, $500,000 in overhead across $10,000,000 in order value gives a 5% overhead rate. Using order value as the denominator ties overhead to the economic weight of each transaction. Revisit this rate quarterly, especially if you add warehouse space or change order mix, because it directly affects your reported cost per order.
Why does fulfillment cost matter more than just shipping cost?
Shipping cost is the most visible line item, but picking and packing labor, packaging materials, and overhead can together exceed the carrier charge—especially for low-value orders. Ignoring these hidden costs leads businesses to underprice products or underestimate the minimum viable order value for profitability. For subscription boxes or high-SKU operations, labor alone can be $2–$5 per order. Tracking all four cost components lets you run accurate contribution margin analysis and make smarter decisions about free shipping thresholds and SKU rationalization.
