Battery Pack Assembly Takt Cost at 72% program share of takt cost: a worked example

This worked example runs the battery pack assembly takt cost numbers for a tougher week than the baseline: 72% program share of takt cost instead of the typical 100%. Estimate the labor and overhead cost tied to a battery pack assembly takt plan.

The inputs for this scenario

  • Planned battery packs: 420 packs (held at the documented default)
  • Cost per pack takt slot: 185 $ / pack (held at the documented default)
  • Program share of takt cost: 72 % (the input this scenario stresses; the baseline uses 100)
  • Fixed pack launch/setup cost: 6,500 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable pack takt cost = planned battery packs × cost per pack takt slot × program share.
  • Total pack takt cost works out to 62,444 $ at these inputs, and this is the headline figure for the scenario.
  • Cost per planned pack works out to 149 $ / pack at these inputs.
  • Variable pack takt cost works out to 55,944 $ at these inputs.
  • Fixed pack launch/setup cost works out to 6,500 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where program share of takt cost sits at 100% and the headline result is 84,200 $, this scenario comes in 25.84% below the baseline at 62,444 $.
  • Use it when allocating a shared takt-paced pack assembly line to a single battery program, or when quoting a build to confirm the per-pack cost covers both line time and launch. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Total pack takt cost: 62,444 $ (headline result)
  • Cost per planned pack: 149 $ / pack
  • Variable pack takt cost: 55,944 $
  • Fixed pack launch/setup cost: 6,500 $
