Customer Revision Cost at 86% billable revision capture: a worked example

Push billable revision capture up to 86% and the picture changes. This example computes every intermediate figure at that operating point. a sales engineer needs to decide whether a customer revision should be charged or absorbed

The inputs for this scenario

  • Revision hours or change line items: 3.5 hr or items (unchanged)
  • Revision engineering/CAD rate: 85 $ / hr or $ / item (unchanged)
  • Billable revision capture: 86 % (raised for this scenario; the documented default is 75)
  • Re-quote and re-setup charge: 40 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Captured revision value = revision hours or line items × revision service rate × billable capture) to the inputs above produces each figure below.
  • At this operating point the engine returns 296 $ for customer revision cost, the number this scenario is built around.
  • At this operating point the engine returns 84.53 $ / hr or $ / item for revision service rate.
  • At this operating point the engine returns 256 $ for captured revision value.
  • At this operating point the engine returns 40 $ for re-quote/setup charge.

How this compares with the baseline

  • Against the tool's baseline example, where billable revision capture sits at 75% and the headline result is 263 $, this scenario comes in 12.44% above the baseline at 296 $.
  • It computes the total chargeable revision cost by multiplying revision hours or change line items by your service rate and a billable-capture percentage, then adding a flat re-quote/setup charge. 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.
