Customer Revision Cost at 54% billable revision capture: a worked example

This worked example runs the customer revision cost numbers for a tougher week than the baseline: 54% billable revision capture instead of the typical 75%. Estimate cost for customer-driven CAD revisions, re-quotes, file repair, and quote updates.

The inputs for this scenario

  • Revision hours or change line items: 3.5 hr or items (held at the documented default)
  • Revision engineering/CAD rate: 85 $ / hr or $ / item (held at the documented default)
  • Billable revision capture: 54 % (the input this scenario stresses; the baseline uses 75)
  • Re-quote and re-setup charge: 40 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Captured revision value = revision hours or line items × revision service rate × billable capture.
  • Customer revision cost works out to 201 $ at these inputs, and this is the headline figure for the scenario.
  • Revision service rate works out to 57.33 $ / hr or $ / item at these inputs.
  • Captured revision value works out to 161 $ at these inputs.
  • Re-quote/setup charge works out to 40 $ at these inputs.

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 23.74% below the baseline at 201 $.
  • Use it the moment a customer requests a geometry, material or finish change after a quote has been issued or a build has been scheduled. 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
