Packaging Protection Cost at 69% special-handling share: a worked example

What does the result look like when special-handling share reaches 69%? The full calculation is worked below with real intermediate numbers. A shipping coordinator prices compliant packaging for a magnet order destined for air freight.

The inputs for this scenario

  • Magnets packed: 600 pieces (unchanged)
  • Protective packaging rate: 3.2 $/piece (unchanged)
  • Special-handling share: 69 % (raised for this scenario; the documented default is 60)
  • Air-freight magnet declaration fee: 450 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Total packaging = magnets packed x packaging rate x special-handling share + declaration fee) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,775 $ for total packaging protection cost, the number this scenario is built around.
  • At this operating point the engine returns 2.96 $ / piece for packaging protection cost per unit.
  • At this operating point the engine returns 1,325 $ for variable packaging protection cost.
  • At this operating point the engine returns 450 $ for fixed packaging protection cost adder.

How this compares with the baseline

  • Against the tool's baseline example, where special-handling share sits at 60% and the headline result is 1,602 $, this scenario comes in 10.79% above the baseline at 1,775 $.
  • A figure at this level is achievable when special-handling share is genuinely sustained, not just peaked for a shift. It uses one blended packaging rate and a single special-handling share, so mixed magnet grades or sizes with very different shielding needs may need to be split into separate runs.

Results at a glance

  • Total packaging protection cost: 1,775 $ (headline result)
  • Packaging protection cost per unit: 2.96 $ / piece
  • Variable packaging protection cost: 1,325 $
  • Fixed packaging protection cost adder: 450 $
