Incident Response Cost at 86% incident scope included: a worked example

Push incident scope included up to 86% and the picture changes. This example computes every intermediate figure at that operating point. Use it when budgeting tabletop findings, OT response retainers, recovery exercises, or cyber incident cost scenarios.

The inputs for this scenario

  • OT response work packages: 24 work packages (unchanged)
  • Cost per response work package: 6,500 $ / work package (unchanged)
  • Incident scope included: 86 % (raised for this scenario; the documented default is 75)
  • Fixed incident coordination cost: 30,000 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable incident response cost = OT response work packages × cost per response work package × incident scope included) to the inputs above produces each figure below.
  • At this operating point the engine returns 164,160 $ for total incident response cost, the number this scenario is built around.
  • At this operating point the engine returns 6,840 $ / work package for cost per response work package.
  • At this operating point the engine returns 134,160 $ for variable incident response cost.
  • At this operating point the engine returns 30,000 $ for fixed incident coordination cost.

How this compares with the baseline

  • Against the tool's baseline example, where incident scope included sits at 75% and the headline result is 147,000 $, this scenario comes in 11.67% above the baseline at 164,160 $.
  • It estimates total incident response cost by scaling response work packages by their unit cost and the share of scope in play, then adding fixed coordination cost. 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.

Results at a glance

  • Total incident response cost: 164,160 $ (headline result)
  • Cost per response work package: 6,840 $ / work package
  • Variable incident response cost: 134,160 $
  • Fixed incident coordination cost: 30,000 $
