Order Fulfillment Cost at 72% cost allocation share to this channel: a worked example

Suppose cost allocation share to this channel falls to 72%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimates the all-in cost to fulfill a batch of orders including variable touch costs and facility overhead.

The inputs for this scenario

  • Orders Fulfilled per Period: 6,000 orders (held at the documented default)
  • Variable Pick-Pack-Ship Cost per Order: 5.5 $/order (held at the documented default)
  • Cost Allocation Share to This Channel: 72 % (the input this scenario stresses; the baseline uses 100)
  • WMS & Facility Fixed Overhead: 8,000 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Total fulfillment = orders x variable cost per order x allocation % + facility overhead.
  • Total order fulfillment cost works out to 31,760 $ at these inputs, and this is the headline figure for the scenario.
  • Order fulfillment cost per unit works out to 5.29 $ / piece at these inputs.
  • Variable order fulfillment cost works out to 23,760 $ at these inputs.
  • Fixed order fulfillment cost adder works out to 8,000 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where cost allocation share to this channel sits at 100% and the headline result is 41,000 $, this scenario comes in 22.54% below the baseline at 31,760 $.
  • It computes total fulfillment cost and cost per order from orders, a variable per-order cost, an allocation percentage, and a fixed facility overhead adder. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.
