Carton Cost Per Unit with total carton cost of 9,000 $: a worked example

What does the result look like when total carton cost reaches 9,000 $? The full calculation is worked below with real intermediate numbers. Use it to compare carton and corrugate cost across box sizes, board grades, or suppliers and to right-size cartons before they inflate freight.

The inputs for this scenario

  • Total carton cost: 9,000 $ (raised for this scenario; the documented default is 3,600)
  • Units shipped: 3,000 units (unchanged)
  • Unit conversion factor: 1 x (unchanged)

Working through the calculation

  • Applying the documented formula (Carton cost per unit = total carton cost รท units shipped) to the inputs above produces each figure below.
  • At this operating point the engine returns 3 $ / unit for carton cost per unit, the number this scenario is built around.
  • At this operating point the engine returns 3 $ / unit for cost per unit before conversion.
  • At this operating point the engine returns 1 x for unit conversion factor.
  • At this operating point the engine returns 3,000 units for units shipped.

How this compares with the baseline

  • Against the tool's baseline example, where total carton cost sits at 3,600 $ and the headline result is 1.2 $ / unit, this scenario comes in 150% above the baseline at 3 $ / unit.
  • A figure at this level is achievable when total carton cost is genuinely sustained, not just peaked for a shift. A blended average across SKUs with different case packs hides which products are over-boxed; split by case configuration when carton spend varies widely by SKU.

Results at a glance

  • Carton cost per unit: 3 $ / unit (headline result)
  • Cost per unit before conversion: 3 $ / unit
  • Unit conversion factor: 1 x
  • Units shipped: 3,000 units
