Warehouse Labor Cost per Order at 92% productive labor utilization: a worked example

What does the result look like when productive labor utilization reaches 92%? The full calculation is worked below with real intermediate numbers. A fulfillment manager uses it to benchmark labor cost per order against a 3PL quote.

The inputs for this scenario

  • Orders Picked & Shipped: 5,000 orders (unchanged)
  • Direct Labor Cost per Order: 3.2 $/order (unchanged)
  • Productive Labor Utilization: 92 % (raised for this scenario; the documented default is 80)
  • Supervision & Indirect Labor: 4,500 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Total labor = orders x labor cost per order x utilization % + indirect labor) to the inputs above produces each figure below.
  • At this operating point the engine returns 19,220 $ for total warehouse labor cost per order cost, the number this scenario is built around.
  • At this operating point the engine returns 3.84 $ / piece for warehouse labor cost per order cost per unit.
  • At this operating point the engine returns 14,720 $ for variable warehouse labor cost per order cost.
  • At this operating point the engine returns 4,500 $ for fixed warehouse labor cost per order adder.

How this compares with the baseline

  • Against the tool's baseline example, where productive labor utilization sits at 80% and the headline result is 17,300 $, this scenario comes in 11.1% above the baseline at 19,220 $.
  • A figure at this level is achievable when productive labor utilization is genuinely sustained, not just peaked for a shift. It treats indirect labor as a fixed block over the period entered, so at very low or very high volumes the per-order figure can mislead unless you recalculate at realistic throughput.
