Glass Breakage Cost at 110% glass breakage scope included: a worked example

This scenario runs the glass breakage cost calculation on the strong side: 110% glass breakage scope included, with every other input held at its documented default. prioritizing glass handling improvements and remake allowances

The inputs for this scenario

  • broken glass lites or IGUs: 31 lites (unchanged)
  • average cost per broken lite or IGU: 118 $ / lite (unchanged)
  • glass breakage scope included: 110 % (raised for this scenario; the documented default is 100)
  • fixed breakage handling and remake cost: 760 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable glass breakage cost = broken glass lites or IGUs × average cost per broken lite or IGU × glass breakage scope included) to the inputs above produces each figure below.
  • At this operating point the engine returns 4,784 $ for total glass breakage cost, the number this scenario is built around.
  • At this operating point the engine returns 154 $ / piece for breakage cost per lite or igu.
  • At this operating point the engine returns 4,024 $ for variable glass breakage cost.
  • At this operating point the engine returns 760 $ for fixed breakage handling and remake cost.

How this compares with the baseline

  • Against the tool's baseline example, where glass breakage scope included sits at 100% and the headline result is 4,418 $, this scenario comes in 8.28% above the baseline at 4,784 $.
  • Use it when costing a breakage event or monthly breakage trend, building a business case for handling improvements, or charging back transit damage. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • total glass breakage cost: 4,784 $ (headline result)
  • breakage cost per lite or IGU: 154 $ / piece
  • variable glass breakage cost: 4,024 $
  • fixed breakage handling and remake cost: 760 $
