Seasonal Back-To-School Ramp with back-to-school run quantity of 250 units: a worked example

Push back-to-school run quantity up to 250 units and the picture changes. This example computes every intermediate figure at that operating point. Use it when seasonal back-to-school ramp in office, school and institutional products is being quoted and you need a number you can defend on a phone call.

The inputs for this scenario

  • Back-to-school run quantity (binders, notebooks, lockers): 250 units (raised for this scenario; the documented default is 100)
  • Variable cost per unit (materials + direct run cost): 2.5 $ / unit (unchanged)
  • Fixed cost for the ramp (tooling change, line setup): 75 $ (unchanged)
  • Seasonal labor & overhead adder (overtime, temps): 25 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Total seasonal back-to-school ramp cost = seasonal back-to-school ramp quantity × variable seasonal back-to-school ramp cost + fixed seasonal back-to-school ramp cost + labor and overhead adder) to the inputs above produces each figure below.
  • At this operating point the engine returns 725 $ for total seasonal back-to-school ramp cost, the number this scenario is built around.
  • At this operating point the engine returns 2.9 $ / piece for cost per unit.
  • At this operating point the engine returns 625 $ for variable seasonal back-to-school ramp cost.
  • At this operating point the engine returns 100 $ for fixed seasonal back-to-school ramp adders.

How this compares with the baseline

  • Against the tool's baseline example, where back-to-school run quantity sits at 100 units and the headline result is 350 $, this scenario comes in 107% above the baseline at 725 $.
  • It sums variable run cost (quantity x per-unit cost) plus fixed setup and a seasonal labor/overhead adder, then divides by quantity for cost per unit. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.
