Vending, Kiosk & Self-Service Equipment worked example

Rework Cost at 5.76% share of kiosks sent to rework: a worked example in vending, kiosk & self-service equipment

Here is what the math looks like when conditions slip. We hold every other input steady and drop share of kiosks sent to rework to 5.76%, then walk the calculation through step by step. Estimates rework cost on a vending and kiosk build, covering technician labor, replacement parts, and rework bay setup.

The inputs for this scenario

  • Kiosks built in the period: 400 machines (held at the documented default)
  • Rework labor plus parts per reworked kiosk: 145 $/machine (held at the documented default)
  • Share of kiosks sent to rework: 5.76 % (the input this scenario stresses; the baseline uses 8)
  • Fixed rework bay setup cost: 5,000 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Rework Cost = Machines Built x Rework Labor+Parts x Rework Incidence% + Rework Bay Setup.
  • Total rework cost works out to 8,341 $ at these inputs, and this is the headline figure for the scenario.
  • Rework cost per unit works out to 20.85 $ / piece at these inputs.
  • Variable rework cost works out to 3,341 $ at these inputs.
  • Fixed rework cost adder works out to 5,000 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where share of kiosks sent to rework sits at 8% and the headline result is 9,640 $, this scenario comes in 13.48% below the baseline at 8,341 $.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to share of kiosks sent to rework, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It uses a single average per-machine rework cost, so a run with a few catastrophic teardowns and many quick fixes will be mis-estimated unless you segment the incidence.

Results at a glance

  • Total rework cost: 8,341 $ (headline result)
  • Rework cost per unit: 20.85 $ / piece
  • Variable rework cost: 3,341 $
  • Fixed rework cost adder: 5,000 $
